contentprovide例子(一)
- ContentProvider示例一：联系人数据库在Android开发中，我们经常会需要访问设备的联系人信息。
这时就可以使用ContentProvider来提供联系人数据库的访问功能。
首先，我们需要在文件中声明READ_CONTACTS权限。
然后，我们可以通过ContentResolver类来获取联系人信息，实现对联系人数据库的访问。
我们可以通过以下步骤来实现对联系人数据库的访问：1. 首先，我们需要创建一个继承自ContentProvider的子类，例如ContactsProvider。
在ContactsProvider中，我们需要重写query、insert、update和delete方法，这些方法分别对应了查询、插入、更新和删除操作。
2. 在query方法中，我们可以构建合适的SQL语句，然后通过ContentResolver的query方法来执行查询操作，从而获取联系人信息。
3. 在insert方法中，我们可以通过ContentResolver的insert方法来执行插入操作，向联系人数据库中添加新的联系人信息。
4. 在update方法中，我们可以通过ContentResolver的update方法来执行更新操作，更新联系人数据库中的联系人信息。
5. 在delete方法中，我们可以通过ContentResolver的delete方法来执行删除操作，从联系人数据库中删除指定的联系人信息。
用中获取、添加、更新和删除联系人信息。
- ContentProvider示例二：媒体文件访问除了联系人数据库之外，我们还可以使用ContentProvider来实现对媒体文件的访问。
例如，我们可以访问设备上的音乐文件、视频文件和图片文件。
通过ContentProvider，我们可以实现对媒体文件的查询、插入、更新和删除操作。
要实现对媒体文件的访问功能，我们可以按照以下步骤进行操作：1. 首先，我们需要创建一个继承自ContentProvider的子类，例如MediaProvider。

AndroidN7.0中报错：a...
AndroidN7.0中报错：a...发现问题最近在Android N 上安装Apk时报错：android.os.FileUriExposedException: file:///storage/emulated/0/Download/appName-2.3.0.apk exposed beyond app through Intent.getData()，通过查找相关的资料终于找到了解决的⽅法，下⾯分享给⼤家，话不多说了，来⼀起看看详细的介绍吧。
解决⽅法1、在AndroidManifest.xml中添加如下代码<provider android:name="android.support.v4.content.FileProvider"android:authorities="app的包名.fileProvider"android:grantUriPermissions="true"android:exported="false"><meta-dataandroid:name="android.support.FILE_PROVIDER_PATHS"android:resource="@xml/file_paths" /></provider>注意：authorities：app的包名.fileProvidergrantUriPermissions：必须是true，表⽰授予 URI 临时访问权限exported：必须是falseresource：中的@xml/file_paths是我们接下来要添加的⽂件2、在res⽬录下新建⼀个xml⽂件夹，并且新建⼀个file_paths的xml⽂件（如下图）3、打开file_paths.xml⽂件添加如下内容<?xml version="1.0" encoding="utf-8"?><paths><external-path path="Android/data/app的包名/" name="files_root" /><external-path path="." name="external_storage_root" /></paths>path：需要临时授权访问的路径（.代表所有路径）name：就是你给这个访问路径起个名字4、修改代码适配Android NIntent intent = new Intent(Intent.ACTION_VIEW);//判断是否是AndroidN以及更⾼的版本if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);Uri contentUri = FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".fileProvider", apkFile);intent.setDataAndType(contentUri, "application/vnd.android.package-archive");} else {intent.setDataAndType(Uri.fromFile(apkFile), "application/vnd.android.package-archive");intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);}startActivity(intent);1、⾸先我们对Android N及以上做判断；2、然后添加flags，表明我们要被授予什么样的临时权限3、以前我们直接 Uri.fromFile(apkFile)构建出⼀个Uri,现在我们使⽤FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".fileProvider", apkFile);4、BuildConfig.APPLICATION_ID直接是应⽤的包名总结以上就是这篇⽂章的全部内容了，希望本⽂的内容对⼤家的学习或者⼯作具有⼀定的参考学习价值，如果有疑问⼤家可以留⾔交流，谢谢⼤家对的⽀持。

To use it effectively, you must have:●A solid understanding of fundamental Cocoa development tools and techniques●A basic grasp of blocks●A basic understanding of key-value coding and key-value observing●For playback,a basic understanding of Core Animation(see Core Animation Programming Guide)7Relevant Chapters: “Time and Media Representations” (page 51)Representing and Using Media with AV FoundationThe primary class that the AV Foundation framework uses to represent media is AVAsset.The design of theframework is largely guided by this representation.Understanding its structure will help you to understandhow the framework works.An AVAsset instance is an aggregated representation of a collection of one ormore pieces of media data(audio and video tracks).It provides information about the collection as a whole,such as its title,duration,natural presentation size,and so on.AVAsset is not tied to particular data format.AVAsset is the superclass of other classes used to create asset instances from media at a URL(see“UsingAssets” (page 11))and to create new compositions(see“Editing” (page 9)).Each of the individual pieces of media data in the asset is of a uniform type and called a track.In a typicalsimple case,one track represents the audio component,and another represents the video component;in acomplex composition,however,there may be multiple overlapping tracks of audio and video.Assets mayalso have metadata.A vital concept in AV Foundation is that initializing an asset or a track does not necessarily mean that it isready for use. It may require some time to calculate even the duration of an item (an MP3 file, for example,may not contain summary information). Rather than blocking the current thread while a value is beingcalculated, you ask for values and get an answer back asynchronously through a callback that you defineusing a block.Relevant Chapters: “Using Assets” (page 11)“Time and Media Representations” (page 51)PlaybackAVFoundation allows you to manage the playback of asset in sophisticated ways.To support this,it separatesthe presentation state of an asset from the asset itself.This allows you to,for example,play two differentsegments of the same asset at the same time rendered at different resolutions.The presentation state for anasset is managed by a player item object;the presentation state for each track within an asset is managedby a player item track ing the player item and player item tracks you can,for example,set thesize at which the visual portion of the item is presented by the player,set the audio mix parameters andvideo composition settings to be applied during playback,or disable components of the asset during playback.You play player items using a player object, and direct the output of a player to Core Animation layer. OniOS 4.1 and later, you can use a queue player to schedule playback of a collection of player items in sequence. 8Representing and Using Media with AV FoundationRelevant Chapters: “Playback” (page 19)Reading,Writing,and Reencoding AssetsAV Foundation allows you to create new representations of an asset in several ways. You can simply reencode an existing asset, or—on iOS 4.1 and later—you can perform operations on the contents of an asset and save the result as a new asset.You use an export session to reencode an existing asset into a format defined by one of a small number of commonly-used presets. If you need more control over the transformation, on iOS 4.1 and later you can use an asset reader and asset writer object in tandem to convert an asset from one representation to another. Using these objects you can,for example,choose which of the tracks you want to be represented in the output file,specify your own output format,or modify the asset during the conversion process.To produce a visual representation of the waveform,you use an asset reader to read the audio track of an asset.Relevant Chapters: “Using Assets” (page 11)ThumbnailsTo create thumbnail images of video presentations,you initialize an instance of AVAssetImageGenerator using the asset from which you want to generate thumbnails.AVAssetImageGenerator uses the default enabled video track(s)to generate images.Relevant Chapters: “Using Assets” (page 11)Media Capture and Access to CameraRecording input from cameras and microphones is managed by a capture session.A capture session coordinates the flow of data from input devices to outputs such as a movie file.You can configure multiple inputs and outputs for a single session,even when the session is running.You send messages to the session to start and stop data flow.In addition,you can use an instance of preview layer to show the user what a camera is recording. Relevant Chapters: “Media Capture” (page 29)EditingAV Foundation uses compositions to create new assets from existing pieces of media(typically,one or more video and audio tracks).You use a mutable composition to add and remove tracks,and adjust their temporal orderings.You can also set the relative volumes and ramping of audio tracks;and set the opacity,and opacity Representing and Using Media with AV Foundation9ramps,of video tracks.A composition is an assemblage of pieces of media held in memory.When you exporta composition using an export session, it's collapsed to a file. On iOS 4.1 and later, you can also create anasset from media such as sample buffers or still images using an asset writer.AV Foundation’s Audio-Related ClassesThere are two facets to the AV Foundation framework—API related just to audio, which was available priorto iOS 4; and API introduced in iOS 4 and later. The older audio-related classes provide easy ways to dealwith audio. They are described in Multimedia Programming Guide,not in this document.●To play sound files,you can use AVAudioPlayer.●To record audio,you can use AVAudioRecorder.You can also configure the audio behavior of your application using AVAudioSession;this is described inAudio Session Programming Guide.Concurrent Programming with AV FoundationCallouts from AV Foundation—invocations of blocks,key-value observers,or notification handlers—are notguaranteed to be made on any particular thread or queue.Instead,AV Foundation invokes these handlerson threads or queues on which it performs its internal tasks.You are responsible for testing whether thethread or queue on which a handler is invoked is appropriate for the tasks you want to perform.If it’s not(for example,if you want to update the user interface and the callout is not on the main thread),you mustredirect the execution of your tasks to a safe thread or queue that you recognize,or that you create for thepurpose.If you’re writing a multithreaded application,you can use the NSThread method isMainThread or[[NSThread currentThread] isEqual:<#A stored thread reference#>]to test whether theinvocation thread is a thread you expect to perform your work on.You can redirect messages to appropriatethreads using methods such as performSelectorOnMainThread:withObject:waitUntilDone:andperformSelector:onThread:withObject:waitUntilDone:modes:.You could also use dispatch_asyncto“bounce”to your blocks on an appropriate queue,either the main queue for UI tasks or a queue you haveup for concurrent operations.For more about concurrent operations,see Concurrency Programming Guide;for more about blocks,see Blocks Programming Topics.10AV Foundation’s Audio-Related ClassesUsing AssetsAsset can come from a file or from media in the user’s iPod Library or Photo library.Simply creating an assetobject,though,does not necessarily mean that all the information that you might want to retrieve for thatitem is immediately available.Once you have a movie asset,you can extract still images from it,transcodeit to another format,or trim the contents.Creating an Asset ObjectTo create an asset to represent any resource that you can identify using a URL,you use AVURLAsset.Thesimplest case is creating an asset from a file:NSURL *url = <#A URL that identifies an audiovisual asset such as a movie file#>;AVURLAsset *anAsset = [[AVURLAsset alloc] initWithURL:url options:nil];Options for Initializing an AssetAVURLAsset’s initialization methods take as their second argument an options dictionary.The only key usedin the dictionary is AVURLAssetPreferPreciseDurationAndTimingKey.The corresponding value is aboolean(contained in an NSNumber object)that indicates whether the asset should be prepared to indicatea precise duration and provide precise random access by time.(Strictly,this and other dictionaries mentionedin this section can use an NSValue object to represent a boolean,however they’re typically represented byan NSNumber object.Recall that NSNumber inherits from NSValue.)Getting the exact duration of an asset may require significant processing ing an approximateduration is typically a cheaper operation and sufficient for playback.Thus:●If you only intend to play the asset,either pass nil instead of a dictionary,or pass a dictionary thatcontains the AVURLAssetPreferPreciseDurationAndTimingKey key and a corresponding value ofNO(contained in an NSNumber object).●If you want to add the asset to a composition(AVMutableComposition),you typically need preciserandom access.Pass a dictionary that contains the AVURLAssetPreferPreciseDurationAndTimingKeykey and a corresponding value of YES(contained in an NSNumber object):NSURL *url = <#A URL that identifies an audiovisual asset such as a movie file#>;NSDictionary *options = [NSDictionary dictionaryWithObject:[NSNumbernumberWithBool:YES]forKey:AVURLAssetPreferPreciseDurationAndTimingKey];AVURLAsset *anAssetToUseInAComposition = [[AVURLAsset alloc] initWithURL:urloptions:nil];Creating an Asset Object112010-11-15 | © 2010 Apple Inc. All Rights Reserved.Accessing the User’s AssetsTo access the assets managed the iPod Library or by the Photos application,you need to get a URL of theasset you want.●To access the iPod Library,you create an MPMediaQuery instance to find the item you want,then getits URL using MPMediaItemPropertyAssetURL.For more about the Media Library,see Multimedia Programming Guide.●To access the assets managed by the Photos application,you use ALAssetsLibrary.The following example shows how you can get an asset to represent the first video in the Saved PhotosAlbum.ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];// Enumerate just the photos and videos group by using ALAssetsGroupSavedPhotos.[library enumerateGroupsWithTypes:ALAssetsGroupSavedPhotosusingBlock:^(ALAssetsGroup *group, BOOL *stop) {// Within the group enumeration block, filter to enumerate just videos.[group setAssetsFilter:[ALAssetsFilter allVideos]];// For this example, we're only interested in the first item.[group enumerateAssetsAtIndexes:[NSIndexSet indexSetWithIndex:0]options:0usingBlock:^(ALAsset *alAsset, NSUInteger index, BOOL*innerStop) {// The end of the enumeration is signaled by asset ==nil.if (alAsset) {ALAssetRepresentation *representation = [alAssetdefaultRepresentation];NSURL *url = [representation url];AVAsset *avAsset = [AVURLAsset URLAssetWithURL:urloptions:nil];// Do something interesting with the AV asset.}}];}failureBlock: ^(NSError *error) {// Typically you should handle an error more gracefullythan this.NSLog(@"No groups");}];[library release];12Creating an Asset Object2010-11-15 | © 2010 Apple Inc. All Rights Reserved.Preparing an Asset for UseInitializing an asset(or track)does not necessarily mean that all the information that you might want toretrieve for that item is immediately available.It may require some time to calculate even the duration of anitem(an MP3file,for example,may not contain summary information).Rather than blocking the currentthread while a value is being calculated,you should use the AVAsynchronousKeyValueLoading protocolto ask for values and get an answer back later through a completion handler you define using a block.(AVAsset and AVAssetTrack conform to the AVAsynchronousKeyValueLoading protocol.)You test whether a value is loaded for a property using statusOfValueForKey:error:.When an asset isfirst loaded,the value of most or all of its properties is AVKeyValueStatusUnknown.To load a value for oneor more properties,you invoke loadValuesAsynchronouslyForKeys:completionHandler:.In thecompletion handler,you take whatever action is appropriate depending on the property’s status.You shouldalways be prepared for loading to not complete successfully,either because it failed for some reason suchas a network-based URL being inaccessible,or because the load was canceled..NSURL *url = <#A URL that identifies an audiovisual asset such as a movie file#>;AVURLAsset *anAsset = [[AVURLAsset alloc] initWithURL:url options:nil];NSArray *keys = [NSArray arrayWithObject:@"duration"];[asset loadValuesAsynchronouslyForKeys:keys completionHandler:^() {NSError *error = nil;AVKeyValueStatus durationStatus = [asset statusOfValueForKey:@"duration"error:&error];switch (durationStatus) {case AVKeyValueStatusLoaded:[self updateUserInterfaceForDuration];break;case AVKeyValueStatusFailed:[self reportError:error forAsset:asset];break;case AVKeyValueStatusCancelled:// Do whatever is appropriate for cancelation.break;}}];If you want to prepare an asset for playback,you should load its tracks property.For more about playingassets,see“Playback” (page 19).Getting Still Images From a VideoTo get still images such as thumbnails from an asset for playback,you use an AVAssetImageGeneratorobject.You initialize an image generator with your asset.Initialization may succeed,though,even if the assetpossesses no visual tracks at the time of initialization,so if necessary you should test whether the asset hasany tracks with the visual characteristic using tracksWithMediaCharacteristic:.AVAsset anAsset = <#Get an asset#>;if ([[anAsset tracksWithMediaCharacteristic:AVMediaTypeVideo] count] > 0) {AVAssetImageGenerator *imageGenerator =[AVAssetImageGenerator assetImageGeneratorWithAsset:anAsset];Preparing an Asset for Use132010-11-15 | © 2010 Apple Inc.

All Rights Reserved.Reading and Writing AssetsYou can easily transcode a movie from one format to another,and trim a movie,using anAVAssetExportSession object. On iOS 4.1 and later, you can also use asset reader and writer objects ifyou need more control over the reading and writing operations.●You use an AVAssetReader object when you want to perform an operation on the contents of an asset.For example,you might read the audio track of an asset to produce a visual representation of thewaveform.●You use an AVAssetWriter object to produce an asset from media such as sample buffers or still images.●You can use an asset reader and asset writer object in tandem to convert an asset from one representationto another with more control over the conversion than you do with AVExportSession.Using an Export SessionAn export session is a controller object that manages asynchronous export of an asset.You initialize thesession using the asset you want to export and the name of a export preset that indicates the export optionsyou want to apply(see allExportPresets).You then configure the export session to specify the outputURL and file type,and optionally other settings such as the metadata and whether the output should beoptimized for network use.You can check whether you can export a given asset using a given preset usingexportPresetsCompatibleWithAsset:as illustrated in this example:AVAsset *anAsset = <#Get an asset#>;NSArray *compatiblePresets = [AVAssetExportSessionexportPresetsCompatibleWithAsset:anAsset];if ([compatiblePresets containsObject:AVAssetExportPresetLowQuality]) {AVAssetExportSession *exportSession = [[AVAssetExportSession alloc]initWithAsset:anAsset presetName:AVAssetExportPresetLowQuality];// Implementation continues.}You complete configuration of the session by providing the output URL(the URL must be a file URL)andsetting the the output file type using outputFileType..You can also specify additional properties such asthe time range,a limit for the output file length,whether the exported file should be optimized for networkuse,and a video composition.The following example illustrates how to use the timeRange property to trimthe movie:exportSession.outputURL = <#A file URL#>;exportSession.outputFileType = AVFileTypeQuickTimeMovie;CMTime start = CMTimeMakeWithSeconds(1.0, 600);16Reading and Writing Assets2010-11-15 | © 2010 Apple Inc.

Android13_IPC方式之ContentProvider
Android13_IPC⽅式之ContentProviderContentProvider是安卓提供的专门⽤于不同应⽤间进⾏数据共享的⽅式；它天⽣适合进程间通信；和Messenger⼀样，ContentProvider的底层实现同样也是Binder；ContentProvider还是四⼤组件之⼀；其实ContentProvider的使⽤涉及的细节还是很多的；⼀般来讲ContentProvider⽤于对应⽤的数据库进⾏增删改查；我们可以访问跨应⽤地其他应⽤提供的ContentProvider，也可以⾃定义⼀个ContentProvider；⾃⼰实现ContentProvider要⾃定义⼀个类继承⾃ContentProvider并实现六个抽象⽅法：onCreate、query、update、insert、delete、getType；1、⾸先在Manifest中注册ContentProvider组件：android:autorities 是作为标识，⼀般⽤完整包名加类名android:permission 表⽰权限，其他应⽤想要⽤这个ContentProvider时，继续声明该权限才可以，否则外界应⽤会异常终⽌；android:process 这⾥为了演⽰⽅便，直接在同⼀个应⽤中开启多进程模式，MainActivity⼀个进程，ContentProvider⼀个进程；2、编写DbOpenHelper类这个类⽤于管理数据的创建、升级、降级package com.example.learncontentprovider;import android.content.Context;import android.database.sqlite.SQLiteDatabase;import android.database.sqlite.SQLiteOpenHelper;import android.util.Log;//利⽤SQLiteHelper来管理数据库的创建、升级、降级public class DbOpenHelper extends SQLiteOpenHelper {private static final String TAG = "DbOpenHelper";private static final String DB_NAME = "book_provider.db";public static final String BOOK_TABLE_NAME="book";public static final String USER_TABLE_NAME="user";private static final int DB_VERSION = 1;//建表语句图书和⽤户信息表private String CREATE_BOOK_TABLE = "CREATE TABLE IF NOT EXISTS "+BOOK_TABLE_NAME+"(_id INTEGER PRIMARY KEY,"+"name TEXT)";private String CREATE_USER_TABLE="CREATE TABLE IF NOT EXISTS "+USER_TABLE_NAME+"(_id INTEGER PRIMARY KEY,"+"name TEXT,"+"sex INT)";public DbOpenHelper(Context context){super(context,DB_NAME,null,DB_VERSION);}@Overridepublic void onCreate(SQLiteDatabase db) {Log.d(TAG,"onCreate");db.execSQL(CREATE_BOOK_TABLE);db.execSQL(CREATE_USER_TABLE);}//⽤于对数据库进⾏升级的，是否执⾏该⽅法要看DbOpenHelper构造函数传⼊的version是否⽐之前更⼤。
Chroma8000问题搜集
Chroma8000问题搜集Chroma8000问题搜集在台湾电源论坛上看到关于Chroma 8000的问题讨论，觉得对我们熟悉Chroma 8020有较大的帮助，故整理如下。
1 关于CHROMA 8000的问题提问(1)8000软件打不开,屏幕显示“Unrecognized database format d://….// Usermanage .mdb”.对此,我每次在其它ATE上COPY其文档.有时可以打开8000,但有时却不能,仍显示上述出错信息.这样只能重装软件,造成大量资料丢失吗?(2) 6011抓取时间不良,测量Turn on &Sequence Test 与Hold up & Sequence Test 时抓取不到时间值,但产品起机正常.(3)6011测量Noise 时常出现警报信息,如“Error On Calling Test Command “Get All 6011_Noise ”! Read All 6011_Noise (Vpp_Nosie_temp=0.000000,0.000000)Device Message: Time out expired before operation completed!” 附图如下:比较模糊,呵呵…(4)8000自检时,出现“ NO Listeners condition is detected (bo th NRFD and NDAC are deasserted .”与“Identification query failed.”这两个是什么意思呢?为什么出现这种情况呢?(5)测量Nosie时,采用TI: Nosie Test 时可以通过,但采用TI: Total Regulation With Nosie Test 时却不能通过,它们的NOISE读值往往相差几十个mv.难道是后者测量NOISE 时不稳定造成的吗?这两个TI从效率、准确度、稳定性等方面来讲,用那一个好一些呢?(6)针对同一产品,若OLP测试OK,则Short Circuit Test 一定可以通过吗?主要是以节省时间而言!即同时存在两项测试,可以删掉后者吗?(7)若编写的TI 要求同时测试两个产品, 其Short Circuit Test 中其Pin读值准确吗?因其PA只有一个Channel ,当其中一颗UUT短路时,其另一颗却正常输出.这种测量方式合理吗?(8)Short Circuit Test 中,设定有时是空载,有时是吃载(轻载与满载).它们的区别是什么呢?8000中应当设定为那种呢?其Trigger点呢?如果采用手动测试短路时的输入功率其吃载量呢?而且实际测量时功率分析仪显示示值不太稳定,且跳动较大.(9)同一产品,其空载时电压跳动,为什么在8000中测量不出来呢?附产品规格:5V 5当264V, 0A时,其输出为4.3V左右,明显FAIL!!!(手测时)(10)在一个程式中,当short ,olp, ovp测试时,其电压均不能回复,不能进行下一步测试,但每一个TI单独测试时OK!调整其TIME OUT & DELAY TIME 后情况还是一样!( UUT 为200w)(11)在测试5W系列小产品时,设定为115V,100% LOAD,但有时6334只出现电压示值显示,而无电流显示.DOWN机处理后出现同样问题!(12)用两台ATE在测试Total Regulation With Nosie Test时,其NOISE读值为什么相差有10mv左右,(同一产品,同一程式)从而造成不能判断该产品是否存在杂讯不良.(13)测量Hold up 时间,其Compare Point 一般设定为百分之多少呢?如95%,97%;但针对240W产品时,其输出为24V,10A要求关机时间大于60ms,设定为99%可以吗?但实际测试时,往往不能通过.(14)用6334组合平台单独进行开机测试时,为什么输出端反接(如DC 线材焊反)时,6334不报警呢?(15)63030其额定功率为300W,但测试240W产品时,为什么其会出现OPP呢?这样就只好并联电子负载了!(规格:24V,10A)(16)有一句英文,没看明白!呵呵,客户问我的!V1 is protected on hiccup mode. The SCP(Short Circuit Protected) is auto recovery.

Mobile应用开发中给自己的应用程序签名
Mobile应用开发中给自己的应用程序签名王永辉Windows Mobile 5开始，Pocket PC和Smartphone上都使用数字签名的方法对应用程序进行验证，减少系统被不明来源的程序危害的可能。
这样就给应用程序开发带来一些不便，如果不进行签名，在运行的时候将出现提示，或者一些驱动无法加载。
Windows Mobile 5 SDK中包含了一个能够安装到移动设备的证书以及对应这个证书的一系列签名，供开发者在调试程序的时候使用。
相关的文件都在？:\Program Files\Windows CE Tools\wce500\Windows Mobile 5.0 Pocket PC SDK\Tools这个目录下。
安装了Windows Mobile 5 SDK的用户可以很容易找到这个目录。
具体步骤：1.在设备上安装sdk certificates。
将该目录下的SdkCerts.cab复制到设备，并安装。
2.在开发过程中，设置工程的Authenticode Signing，将程序签名：(1)Project->...Properties或者其他方式(Alt+F7等等）打开工程属性设置页面。
(2)在Configuration Properties中选择Authenticode Signing，设置Authenticode Signature = YES；按下Certificate栏目右边的...，出现"Select Certificate"窗口，如果第一次使用，需要导入证书，按下"manage certificates"，然后按下"Import"，在Certificate Import Wizard"中，选择pfx类型的文件，Browse到？:\Program Files\Windows CE Tools\wce500\Windows Mobile 5.0 Pocket PC SDK\Tools目录，依据权限需求从3个证书种选择一个，然后导入到Personal下，这样退出Wizard后就可以看到刚才导入的证书，直接选择，Close，Certificate栏目就有了证书；Provision Device依据权限选择就可以。
contentprovider 使用实例
一、什么是contentproviderContentProvider是Android中的四大组件之一，用于管理应用程序的私有数据并提供对这些数据的访问权限。
通过ContentProvider，应用程序之间可以共享数据，并且可以实现数据的增删改查等操作。
二、ContentProvider的基本使用1. 创建ContentProvider要创建一个ContentProvider，需要继承自android.content.ContentProvider类，并实现其中的一些方法，包括onCreate(), query(), insert(), update(), delete()等方法。
在AndroidManifest.xml文件中需要注册ContentProvider，声明该Provider所管理的数据的URI。
2. 数据库操作在ContentProvider中，一般会使用SQLite数据库来存储数据。
在实现query(), insert(), update(), delete()等方法时，需要使用SQLiteOpenHelper来创建、打开、关闭数据库，并使用SQLiteDatabase对象进行数据的增删改查操作。
3. ContentResolver的使用在应用程序中，通过ContentResolver来访问ContentProvider提供的数据。
ContentResolver是一个用于访问ContentProvider的核心类，它可以通过ContentProvider所提供的URI来操作相应的数据。
4. 权限控制在ContentProvider中，可以通过权限控制来限制其他应用程序对数据的访问。
可以在AndroidManifest.xml中声明ContentProvider所需要的权限，并在ContentProvider的实现中对权限进行验证。
三、ContentProvider的使用示例下面以一个简单的学生信息管理系统为例，演示ContentProvider的基本使用。

ContentProvider的使用
知识解析
ContentProvider
什么是Content provider？它是Android应用程序的四大组成部分之一，是Android中的跨应用访问数据机制。
为何需要content provider？ Android中每一个app的资源是私有的，其他app不可访问它的数据，但可以通过content
provider和其他app共享私有数据。
ContentProvider通过URI来向其他的app提供访问路径。
URI的组成如下图所示。
A：标准前缀，用来说明一个Content
Provider控制这些数据，对于自定义ContentProvider来说，就是“content:/ /”，我们无法改变；
B：URI的标识，它定义了是哪个Content
Provider提供这些数据。
对于第三方应用程序，为了保证URI标识的唯一性，它必须是一个完整的、小写的包名+类名。
这个标识在<provider> 元素的authorities属性中说明：
<provider name=”.TransportationProvider”
authorities=”com.example.myproject.transportationprovi
der” . . . >
C：路径，Content
Provider使用这些路径来确定当前需要的是什么类型的数据，URI中可能不包括路径，也可能包括多层；通常这里对应的是某个表或者视图的名字
D：如果URI中包含，表示需要获取的记录的ID；如果没有ID，就表示返回全部；
由于URI通常比较长，而且有时候容易出错，且难以理解。
所以，对于Android 的内置App如通讯录等，定义了一些辅助类，并且定义了一些常量来代替这些长字符串，例如：ContactsContract.Contacts.CONTENT_URI
ContentResolver
ContentProvider可将Content分享至不同的应用程序之中，而ContentRes olver则是一个标准的方式来取得ContentProvider所提供的数据，也是用来修改数据的方法，但若牵涉到写入或修改数据的话，则要看目标的ContentProvi der是否允许用户对数据做存取的操作，若无此权限，则ContentResolver方法会失败。
ContentProvider通常会使用URI的方式来当作分享数据的依据，故在ContentR esolver要读取某一ContentProvider数据时则必须将要读取的URI当成参数来使用。
ContentResolver使用query()来对指定URI的ContentProvider进行查询，它的参数包括下表中列出的各项。
和SQLiteDatabase的query()基本类似，除了这里提供的是一个uri而不是表名。
它也包括对数据进行其他增、删、改的操作方法，如下表。
可以通过Context上的getContentResolver()来获得一个ContentResolver 对象。
Android自带的应用例如通讯录，也通过ContentProvider向外提供了数据访问接口，我们可以通过ContentREsolver访问它。
下面我们看一下和通讯录相关的ContentProvider信息：
联系人信息URI： ContactsContract.Contacts.CONTENT_URI
电话信息：
monDataKinds.Phone.CONTENT_URI：其中，ContactsC monDataKinds.Phone.CONTACT_ID是ContactsContract.Contacts. _ID的外键
邮件信息： monDataKinds.Email
聊天工具信息： monDataKinds.Im
网站： monDataKinds.Website
职业素质
ContentProvider：为存储和获取数据提供统一的接口。
可以在不同的应用程序之间共享数据。
Android已经为常见的一些数据提供了默认的ContentPr ovider。
