android读写文件权限流程
Android读写文件权限流程概述在A nd ro id开发中，应用程序需要获取特定的权限以便能够读取和写入设备上的文件。
本文将介绍An dr oi d中读写文件权限的流程，帮助开发者了解如何正确处理文件访问权限相关的问题。
为什么需要文件权限A n dr oi d系统为了保护用户的隐私和数据安全，对应用程序的文件访问进行了限制。
如果应用程序想要读取或写入设备上的文件，必须首先获取相应的权限。
否则，在没有权限的情况下进行文件操作将会引发安全异常。
文件读取权限步骤1：在A n d r o i dM a n i f e s t.x m l中声明权限要读取设备上的文件，首先需要在应用的清单文件（A nd ro id Ma ni fe st.xm l）中声明文件读取权限。
可以使用以下代码将读取权限添加到清单文件中：<u se s-p e rm is si on an dr oid:na me="an dr oi d.p e rm is si on.R EA D_E X TE RN AL_ S T OR AG E"/>这个权限允许应用程序读取外部存储（如S D卡）上的文件。
步骤2：检查权限在代码中进行文件读取操作前，需要先检查应用是否已经获得了文件读取权限。
可以使用以下代码来检查权限：i f(C on te xt Co mp at.c he ck Se lf Pe rm iss i on(c on te xt,M ani f es t.p e r mi ss io n.RE AD_EX T ER NA L_ST OR AG E)!=Pa ck ag eM an ag er.P ER MI SS I O N_G RA NT ED){//没有读取权限，请求权限}e ls e{//已经有读取权限，进行文件读取操作}步骤3：请求权限如果在步骤2中检查到没有读取权限，应该向用户请求获取该权限。
android读写文件权限流程
android读写文件权限流程
一、 Android读写文件权限介绍
Android SDK提供了文件 I/O 的功能，它使开发人员可以使用简单
的API操作本地文件系统。
在Android 6.0 及更高版本中，对文件I/O，
用户必须显式地获取权限才能继续进行操作。
Android针对本地文件读写，提供了相应的权限控制，主要有类似的
内容：
1、读取外部存储文件权限：
2、写入外部存储文件权限：
二、Android文件读写权限流程
Android读写文件权限的整个流程如下：
1、应用开发者在AndroidManifest文件中声明
“android.permission.READ_EXTERNAL_STORAGE”和
“android.permission.WRITE_EXTERNAL_STORAGE”权限；
2、当用户启动应用的时候，系统会检测应用是否声明了需要申请的
权限；
3、如果声明了需要申请的权限，系统就会向用户发出权限请求提示；
4、用户选择同意或拒绝；
5、如果用户同意，系统会授予该应用相应的权限；
6、如果用户拒绝，应用就无法使用该权限。
三、Android文件读写权限的注意事项
1、在Android 6.0及更高版本中，开发者需要在AndroidManifest 中声明需要申请的权限；
2、在申请权限的时候，要确保用户理解其申请的权限；
3、如果用户拒绝权限，应用就无法使用该权限；。

version="1.0" encoding="utf-8"?><paths><!-- name随便起--><external-pathname="camera_photos"path="/"/></paths>2.配置系统需要⽤到的系统权限<!-- 向SD卡写⼊数据权限 --><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/><uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/><uses-permissionandroid:name="android.permission.WRITE_SETTINGS"tools:ignore="ProtectedPermissions"/>3.编写申请动态权限⽅法，在onCreate()⽅法中调⽤//申请权限private boolean getPermission(Activity activity){boolean rs=false;// 声明⼀个集合，在后⾯的代码中⽤来存储⽤户拒绝授权的权List<String> permissionList = new ArrayList<>();String[] permissions = new String[]{Manifest.permission.READ_EXTERNAL_STORAGE,//读取内存卡Manifest.permission.WRITE_EXTERNAL_STORAGE,//写⼊内存卡// Manifest.permission.MOUNT_UNMOUNT_FILESYSTEMS,//允许挂载和反挂载⽂件系统可移动存储// Manifest.permission.READ_PHONE_STATE,//读取⼿机状态和⾝份/* Manifest.permission.ACCESS_WIFI_STATE,//获取使⽤Wi-Fi等WLAN⽆线⽹络Manifest.permission.CHANGE_WIFI_STATE,//允许程序改变Wi-Fi连接状态Manifest.permission.ACCESS_NETWORK_STATE,//允许程序访问有关GSM⽹络信息Manifest.permission.CHANGE_NETWORK_STATE,//允许程序改变⽹络连接状态Manifest.permission.INTERNET,//访问⽹络连接，可能产⽣GPRS流量Manifest.permission.BLUETOOTH,//允许程序连接到已配对的蓝⽛设备Manifest.permission.CAMERA,//相机Manifest.permission.WRITE_SETTINGS,//允许程序读取或写⼊系统设置*/};permissionList.clear();for (int i = 0; i < permissions.length; i++) {if (ContextCompat.checkSelfPermission(activity, permissions[i]) != PackageManager.PERMISSION_GRANTED) {Log.e(TAG,"权限未允许："+permissions[i]+"....");permissionList.add(permissions[i]);}}if (permissionList.isEmpty()) {//未授予的权限为空，表⽰都授予了Log.e(TAG,"已经获取到了所有权限");return true;} else {//请求权限⽅法String[] spermissions = permissionList.toArray(new String[permissionList.size()]);//将List转为数组ActivityCompat.requestPermissions(activity, spermissions, 1);}return rs;}4.处理授权回调@Overridepublic void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {super.onRequestPermissionsResult(requestCode, permissions, grantResults);if(requestCode==1){if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {boolean request_rs=true;for(int i=0;i<grantResults.length;i++){if (grantResults[i] != PackageManager.PERMISSION_GRANTED) {request_rs=false;}}if(request_rs){Log.e("软件获取权限结果：","获取软件权限成功");init();}else{Toast.makeText(this, "您拒绝了软件应⽤权限，因此⽆法使⽤该软件！", Toast.LENGTH_LONG).show(); showDialogTipUserGoToAppSettting();}}}}若未获取的权限，则提醒⽤户⼿动开启权限/*** 提⽰⽤户去应⽤设置界⾯⼿动开启权限*/private void showDialogTipUserGoToAppSettting() {new AlertDialog.Builder(this).setTitle("存储权限不可⽤").setMessage("请在-应⽤设置-权限-中，允许应⽤使⽤存储权限来保存⽤户数据").setPositiveButton("⽴即开启", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {// 跳转到应⽤设置界⾯goToAppSetting();android.os.Process.killProcess(android.os.Process.myPid());}}).setNegativeButton("取消", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {android.os.Process.killProcess(android.os.Process.myPid());}}).setCancelable(false).show();}/*** 跳转到当前应⽤的设置界⾯*/private void goToAppSetting() {Intent intent = new Intent();intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);Uri uri = Uri.fromParts("package", getPackageName(), null);intent.setData(uri);startActivityForResult(intent, 123);}⼆、调⽤应⽤打开本地⽂件第⼀种，根据⽂件类型⾃动选取应⽤打开⽂件1.创建⽂件类型数组/*** -- MIME 列表 --*/public static final String[][] MIME_MapTable = {// --{后缀名， MIME类型} --{".3gp", "video/3gpp"},{".3gpp", "video/3gpp"},{".aac",

详解Android权限管理之RxPermission解决Android6.0适配问题
详解Android权限管理之RxPermission解决Android6.0适配问题前⾔：上篇重点学习了Android 6.0的运⾏时权限，今天还是围绕着Android 6.0权限适配来总结学习，这⾥主要介绍⼀下我们公司解决Android 6.0权限适配的⽅案：RxJava+RxPermission。
这⾥不再介绍Android 6.0运⾏时权限了，直接看下如何使⽤RxPermission。
RxPermission：⽤于适配Android 6.0新的权限模型的开源框架。
下载地址：如何使⽤？1.）在app module的build.gradle中添加如下配置使⽤该开源框架minSdkVersion 必须⼩于9repositories {jcenter() // If not already there}dependencies {compile 'com.tbruyelle.rxpermissions:rxpermissions:0.9.0@aar'}如果使⽤的RxJava2的话使⽤下⾯的配置与RxJava不同的是包名变成了com.tbruyelle.rxpermissions2，不过说实话RxJava2我还没使⽤过。
dependencies {compile 'com.tbruyelle.rxpermissions2:rxpermissions:0.8.2@aar'}2.）直接申请权限使⽤RxPermissions.getInstance(this)是以单例的形式使⽤的，这⾥以申请拍照权限为例RxPermissions.getInstance(this).request(permissions).subscribe(new Action1<Boolean>() {@Overridepublic void call(Boolean granted) {if (granted) { // 在android 6.0之前会默认返回true// 已经获取权限String jpgPath = getCacheDir() + "test.jpg";takePhotoByPath(jpgPath, 2);} else {// 未获取权限Toast.makeText(MainActivity.this, "您没有授权该权限，请在设置中打开授权", Toast.LENGTH_SHORT).show();}}});这⾥直接返回是否授权，我们可以根据这个值进⾏不同的处理。
安卓手机权限设置
Android 是开放式的系统，G1自带的一部分程序可以删除（前提是手机要有ROOT权限），有的坚决不能删除，注意：手机删除自带程序后有的系统可能会失去硬启功能，如果系统出问题只能刷机解决，（如果备份了系统，可以进行系统恢复），想删除自带程序的朋友必须学会刷机。
我们要用到Root Explorer （高级资源管理器，百度中可以下载到），这个软件要求手机有权限，Root Explorer 的软件安装后，打开会弹出提示，这时候选择“总是同意”如何出现文件夹（没出现，就要重启，应该重启一次，我的就是）接着在文件目录中找到“system”文件夹和“data”文件夹并点击进入。
进入“system”文件夹后再进入“APP”文件夹这时候大家就会看到这里有很多以APk结尾的文件；首先要先点击下右上角的Remount as R/W ，点击后这个按钮就会变成Remount as R/O。
这就说明我们已经获取读写权限了！以系统自带的平衡球游戏—Teeter为例。
我们要先找到Teeter.apk。
然后长按文件名就会弹出对话框，选择Delete就可以删除该程序了，当程序弹出对话框件，选择Y es ，用同样的方法进入“data”文件夹里的“data”文件夹删除Teeter.odex文件。
（记住删除俩个哦）当Teeter.apk与Teeter.odex这两个文件都被删除，system”里还有个media文件夹，media文件夹里还有四个文件夹，是铃声，短信，闹钟，相机声音文件夹，我可以把四个文件夹复制到SD的根目录下（复制到卡后，可以保留几闹钟音和相机声音，其他的铃音删除后，把自己喜欢的放进来OK,提醒：相机声音会很小，几乎听不见，其他还可以，），然后可以把整个media文件夹删除，这样大家就可以把自己喜欢的mp3歌曲当铃声了（记得你要先把那四个文件复制到sdcard里啊）退出时注意：我们还要再点击下Remount as R/O把读取权限改为只读，以免误操作！重启手机，看看是不是有变化。
Android设备开发文档说明书
1) What is Android?It is an open-sourced operating system that is used primarily on mobile devices, such as cell phones and tablets. It is a Linux kernel-based system that’s been equipped with rich components that allows developers to create and run apps that can perform both basic and advanced functions.2) What Is the Google Android SDK?The Google Android SDK is a toolset that developers need in order to write apps on Android enabled devices. It contains a graphical interface that emulates an Android driven handheld environment, allowing them to test and debug their codes.3) What is the Android Architecture?Android Architecture is made up of 4 key components:- Linux Kernel- Libraries- Android Framework- Android Applications4) Describe the Android Framework.The Android Framework is an important aspect of the Android Architecture. Here you can find all the classes and methods that developers would need in order to write applications on the Android environment.5) What is AAPT?AAPT is short for Android Asset Packaging Tool. This tool provides developers with the ability to deal with zip-compatible archives, which includes creating, extracting as well as viewing its contents.6) What is the importance of having an emulator within the Android environment?The emulator lets developers “play” around an interface that acts as if it were an actual mobile device. They can write and test codes, and even debug. Emulators are a safe place for testing codes especially if it is in the early design phase.7) What is the use of an activityCreator?An activityCreator is the first step towards the creation of a new Android project. It is made up of a shell script that will be used to create new file system structure necessary for writing codes within the Android IDE.8 ) Describe Activities.Activities are what you refer to as the window to a user interface. Just as you create windows in order to display output or to ask for an input in the form of dialog boxes, activities play the same role, though it may not always be in the form of a user interface.9) What are Intents?Intents displays notification messages to the user from within the Android enabled device. It can be used to alert the user of a particular state that occurred. Users can be made to respond to intents.10) Differentiate Activities from Services.Activities can be closed, or terminated anytime the user wishes. On the other hand, services are designed to run behind the scenes, and can act independently. Most services run continuously, regardless of whether there are certain or no activities being executed.11) What items are important in every Android project?These are the essential items that are present each time an Android project is created:- AndroidManifest.xml- build.xml- bin/- src/- res/- assets/12) What is the importance of XML-based layouts?The use of XML-based layouts provides a consistent and somewhat standard means of setting GUI definition format. In common practice, layout details are placed in XML files while other items are placed in source files.13) What are containers?Containers, as the name itself implies, holds objects and widgets together, depending on which specific items are needed and in what particular arrangement that is wanted. Containers may hold labels, fields, buttons, or even child containers, as examples.14) What is Orientation?Orientation, which can be set using setOrientation(), dictates if the LinearLayout is represented asa row or as a column. Values are set as either HORIZONTAL or VERTICAL.15) What is the importance of Android in the mobile market?Developers can write and register apps that will specifically run under the Android environment. This means that every mobile device that is Android enabled will be able to support and run these apps. With the growing popularity of Android mobile devices, developers can take advantage of this trend by creating and uploading their apps on the Android Market for distribution to anyone who wants to download it.16) What do you think are some disadvantages of Android?Given that Android is an open-source platform, and the fact that different Android operating systems have been released on different mobile devices, there’s no clear cut policy to how applications can adapt with various OS versions and upgrades. One app that runs on this particular version of Android OS may or may not run on another version. Another disadvantage is that since mobile devices such as phones and tabs come in different sizes and forms, it poses a challenge for developers to create apps that can adjust correctly to the right screen size and other varying features and specs.17) What is adb?Adb is short for Android Debug Bridge. It allows developers the power to execute remote shell commands. Its basic function is to allow and control communication towards and from the emulator port.18) What are the four essential states of an activity?- Active – if the activity is at the foreground- Paused – if the activity is at the background and still visible- Stopped – if the activity is not visible and therefore is hidden or obscured by another activity- Destroyed – when the activity process is killed or completed terminated19) What is ANR?ANR is short for Application Not Responding. This is actually a dialog that appears to the user whenever an application have been unresponsive for a long period of time.20) Which elements can occur only once and must be present?Among the different elements, the and elements must be present and can occur only once. The rest are optional, and can occur as many times as needed.21) How are escape characters used as attribute?Escape characters are preceded by double backslashes. For example, a newline character is created using ‘\\n’22) What is the importance of settings permissions in app development?Permissions allow certain restrictions to be imposed primarily to protect data and code. Without these, codes could be compromised, resulting to defects in functionality.23) What is the function of an intent filter?Because every component needs to indicate which intents they can respond to, intent filters are used to filter out intents that these components are willing to receive. One or more intent filters are possible, depending on the services and activities that is going to make use of it.24) Enumerate the three key loops when monitoring an activity- Entire lifetime – activity happens between onCreate and onDestroy- Visible lifetime – activity happens between onStart and onStop- Foreground lifetime – activity happens between onResume and onPause25) When is the onStop() method invoked?A call to onStop method happens when an activity is no longer visible to the user, either because another activity has taken over or if in front of that activity.26) Is there a case wherein other qualifiers in multiple resources take precedence over locale?Yes, there are actually instances wherein some qualifiers can take precedence over locale. There are two known exceptions, which are the MCC (mobile country code) and MNC (mobile network code) qualifiers.27) What are the different states wherein a process is based?There are 4 possible states:- foreground activity- visible activity- background activity- empty process28) How can the ANR be prevented?One technique that prevents the Android system from concluding a code that has been responsive for a long period of time is to create a child thread. Within the child thread, most of the actual workings of the codes can be placed, so that the main thread runs with minimal periods of unresponsive times.29) What role does Dalvik play in Android development?Dalvik serves as a virtual machine, and it is where every Android application runs. Through Dalvik, a device is able to execute multiple virtual machines efficiently through better memory management.30) What is the AndroidManifest.xml?This file is essential in every application. It is declared in the root directory and contains information about the application that the Android system must know before the codes can be executed.31) What is the proper way of setting up an Android-powered device for app development? The following are steps to be followed prior to actual application development in an Android-powered device:-Declare your application as "debuggable" in your Android Manifest.-Turn on "USB Debugging" on your device.-Set up your system to detect your device.32) Enumerate the steps in creating a bounded service through AIDL.1. create the .aidl file, which defines the programming interface2. implement the interface, which involves extending the inner abstract Stub class as well as implanting its methods.3. expose the interface, which involves implementing the service to the clients.33) What is the importance of Default Resources?When default resources, which contain default strings and files, are not present, an error will occur and the app will not run. Resources are placed in specially named subdirectories under the project res/ directory.34) When dealing with multiple resources, which one takes precedence?Assuming that all of these multiple resources are able to match the configuration of a device, the ‘locale’ qualifier almost always takes the highest precedence over the others.35) When does ANR occur?The ANR dialog is displayed to the user based on two possible conditions. One is when there is no response to an input event within 5 seconds, and the other is when a broadcast receiver is not done executing within 10 seconds.36) What is AIDL?AIDL, or Android Interface Definition Language, handles the interface requirements between a client and a service so both can communicate at the same level through interprocess communication or IPC. This process involves breaking down objects into primitives that Android can understand. This part is required simply because a process cannot access the memory of the other process.37) What data types are supported by AIDL?AIDL has support for the following data types:-string-charSequence-List-Map-all native Java data types like int,long, char and Boolean38) What is a Fragment?A fragment is a part or portion of an activity. It is modular in a sense that you can move around or combine with other fragments in a single activity. Fragments are also reusable.39) What is a visible activity?A visible activity is one that sits behind a foreground dialog. It is actually visible to the user, but not necessarily being in the foreground itself.40) When is the best time to kill a foreground activity?The foreground activity, being the most important among the other states, is only killed or terminated as a last resort, especially if it is already consuming too much memory. When a memory paging state has been reach by a foreground activity, then it is killed so that the user interface can retain its responsiveness to the user.41) Is it possible to use or add a fragment without using a user interface?Yes, it is possible to do that, such as when you want to create a background behavior for a particular activity. You can do this by using add(Fragment,string) method to add a fragment from the activity.42) How do you remove icons and widgets from the main screen of the Android device?To remove an icon or shortcut, press and hold that icon. You then drag it downwards to the lower part of the screen where a remove button appears.43) What are the core components under the Android application architecture?There are 5 key components under the Android application architecture:- services- intent- resource externalization- notifications- content providers44) What composes a typical Android application project?A project under Android development, upon compilation, becomes an .apk file. This apk file format is actually made up of the AndroidManifest.xml file, application code, resource files, and other related files.45) What is a Sticky Intent?A Sticky Intent is a broadcast from sendStickyBroadcast() method such that the intent floats around even after the broadcast, allowing others to collect data from it.46) Do all mobile phones support the latest Android operating system?Some Android-powered phone allows you to upgrade to the higher Android operating system version. However, not all upgrades would allow you to get the latest version. It depends largely on the capability and specs of the phone, whether it can support the newer features available under the latest Android version.47) What is portable wi-fi hotspot?Portable Wi-Fi Hotspot allows you to share your mobile internet connection to other wireless device. For example, using your Android-powered phone as a Wi-Fi Hotspot, you can use your laptop to connect to the Internet using that access point.48) What is an action?In Android development, an action is what the intent sender wants to do or expected to get as a response. Most application functionality is based on the intended action.49) What is the difference between a regular bitmap and a nine-patch image?In general, a Nine-patch image allows resizing that can be used as background or other image size requirements for the target device. The Nine-patch refers to the way you can resize the image: 4 corners that are unscaled, 4 edges that are scaled in 1 axis, and the middle one that can be scaled into both axes.50) What language is supported by Android for application development?The main language supported is Java programming language. Java is the most popular language for app development, which makes it ideal even for new Android developers to quickly learn to create and deploy applications in the Android environment.Guru99 Provides FREE ONLINE TUTORIAL on Various courses likeJava MIS MongoDB BigData CassandraWeb Services SQLite JSP Informatica AccountingSAP Training Python Excel ASP Net HBase ProjectTest Management Business Analyst Ethical Hacking PMP ManagementLive Project SoapUI Photoshop Manual Testing Mobile TestingData Warehouse R Tutorial Tableau DevOps AWSJenkins Agile Testing RPA JUnitSoftware EngineeringSelenium CCNA AngularJS NodeJS PLSQL。
androind manifest 权限定义
androind manifest 权限定义
在AndroidManifest文件中，权限定义通常包括以下几个方面：
- Permission权限：指一系列“Android.Permission.*”对象。
在android.Manifest.permission.java类中可以找到Android定义的所有Permission权限。
如果应用程序需要访问Android通过“Permission”定义的内容，则该应用程序必须在AndroidManifest.xml中配置使用到的“Permission”，否则Android将会拒绝该应用程序访问。
- Root权限：指的是根权限，它允许应用程序执行一些需要超级用户权限的操作，例如修改系统设置或访问受保护的文件。
- Bootloader的解锁：指的是引导加载程序的解锁，它允许应用程序修改设备的引导加载程序，以便进行一些高级的操作，例如刷机或修改系统配置。
- Radio（基带）解锁：指的是基带的解锁，它允许应用程序修改设备的基带，以便进行一些高级的通信操作，例如修改信号强度或切换网络模式。
在定义权限时，开发者应该根据应用程序的需求和安全考虑，选择适当的权限，并在AndroidManifest文件中正确地声明它们。
这样可以确保应用程序的安全性和用户隐私得到保护。
Android应用程序的权限管理与隐私保护
Android应用程序的权限管理与隐私保护随着智能手机的普及，Android应用程序的使用越来越广泛。
然而，与此同时，我们也面临着隐私泄露的风险。
为了保护用户的隐私，Android系统引入了权限管理机制。
本文将探讨Android应用程序的权限管理与隐私保护。
一、权限管理的重要性权限管理是Android系统中的一项重要功能，它允许用户选择应用程序能够访问哪些资源和执行哪些操作。
例如，一个社交媒体应用程序可能需要访问用户的联系人列表和相册，而一个游戏应用程序可能需要访问用户的位置信息。
通过权限管理，用户可以控制应用程序对自己隐私的访问程度，从而保护个人信息的安全。
二、权限分类与授权机制Android系统将权限分为两类：普通权限和危险权限。
普通权限是指应用程序需要的一些基本权限，如访问网络、读取设备状态等。
这些权限在应用程序安装时自动授予，用户无需进行确认。
危险权限是指可能涉及用户隐私的权限，如读取联系人、获取位置信息等。
这些权限需要用户在应用程序运行时进行确认，用户可以选择授权或拒绝。
Android系统的权限授权机制使用了运行时权限模型。
当应用程序需要访问危险权限时，系统会弹出一个对话框，询问用户是否授权。
用户可以选择授权或拒绝。
如果用户选择拒绝，应用程序将无法访问相关权限，但仍可正常使用其他功能。
三、隐私保护的挑战尽管Android系统提供了权限管理机制，但隐私保护仍然面临一些挑战。
首先，一些应用程序可能滥用权限，收集用户的个人信息并用于商业目的。
其次，一些应用程序可能存在漏洞，导致用户的隐私信息被黑客攻击窃取。
此外，一些应用程序可能通过与其他应用程序共享数据，间接泄露用户的隐私。
为了应对这些挑战，用户需要保持警惕。
在安装应用程序时，应仔细阅读权限列表，并考虑应用程序所需权限是否合理。
此外，用户还可以通过安装安全软件来检测应用程序的行为，防止隐私泄露。
四、用户隐私保护的建议为了更好地保护用户隐私，除了权限管理外，我们还可以采取以下措施：1. 定期审查应用程序权限：在设置中，可以找到应用程序权限管理的选项。

Android权限列表permission说明
Android权限分的很细，但命名比较人性化，Android permission比Symbian Capabilities有了不少改进，下面就来看看权限许可都有哪些定义吧，发现还是比较繁多的，如果发现你的程序某个地方调试错误很可能是Android permission的访问控制在作怪，这也是为了安全防止手机成为病毒的场所。
Android开发网获取到的消息来看不用购买高昂的数字签名证书，权限许可权由用户决定而不是手机制造商和平台提供商，这一点不得不说明为Android开发人员着想，下面的信息都是需要添加在androidmanifest.xml文件中。
ACCESS_COARSE_LOCATION是有关错略的位置信息获取，比如说MyLocation API调用获取的Cellid等定位信息必需添加android.permission.ACCESS_COARSE_LOCATION这个声明ACCESS_FINE_LOCATION、ACCESS_LOCATION_EXTRA_COMMANDS、ACCESS_MOCK_LOCATION是有关GPS定位获取的信息使用GPS LocationProvider类的相关定位信息必需声明android.permission.ACCESS_FINE_LOCATION、android.permission.ACCESS_LOCATION_EXTRA_COMMANDS和android.permission.ACCESS_MOCK_LOCATIONACCESS_NETWORK_STATE是获取网络状态的权限控制，如果获取当前GSM网络相关信息必需在androidmanifest.xml中声明android.permission.ACCESS_NETWORK_STATE这句。
ACCESS_SURFACE_FLINGER是使用SurfaceFlinger底层API的令牌，必需声明android.permission.ACCESS_SURFACE_FLINGERACCESS_WIFI_STATE权限可以获取使用Wi-Fi等WLAN无线网络，加入android.permission.ACCESS_WIFI_STATE这句ADD_SYSTEM_SERVICE是系统服务数据库的管理权限，比如添加一个系统服务必需声明android.permission.ADD_SYSTEM_SERVICEBATTERY_STATS是获取Android平台上电池设备的权限令牌，必需声明android.permission.BATTERY_STATS才可以获得电池信息BLUETOOTH蓝牙信息类，获取相关的蓝牙信息必声明android.permission.BLUETOOTHBLUETOOTH_ADMIN是蓝牙管理权限包含了身份安全认证，必需添加android.permission.BLUETOOTH_ADMIN类BRICK"android.permission.BRICK"BROADCAST_PACKAGE_REMOVED是广播包移除类权限，可以移除指定的系统消息，必需声明android.permission.BROADCAST_PACKAGE_REMOVED这句BROADCAST_STICKY"android.permission.BROADCAST_STICKY"CALL_PHONE是允许Android手机拨打电话时使用的权限"android.permission.CALL_PHONE"CALL_PRIVILEGED"android.permission.CALL_PRIVILEGED"CAMERA是摄像头权限控制，可以管理照相功能的启用"android.permission.CAMERA"CHANGE_COMPONENT_ENABLED_STATE"android.permission.CHANGE_COMPONENT_ENABLED_STATE"CHANGE_CONFIGURATION是控制Android系统设置等敏感信息的权限，修改时必需有android.permission.CHANGE_CONFIGURATION声明。

android相机权限申请 文案
android相机权限申请文案在您使用Android设备的相机应用程序时，您可能会遇到需要申请相机权限的情况。
相机权限是一项重要的权限，它允许应用程序访问您的设备相机和拍摄照片。
在申请相机权限之前，让我们了解一下为什么应用程序需要这个权限。
Android相机权限是为了保障用户的隐私和安全而设计的。
当您使用相机应用程序时，它可能需要访问您的相机硬件，以便拍摄照片或录制视频。
这对于各种应用程序来说都是必要的，如社交媒体应用程序、照片编辑应用程序和视频通话应用程序。
然而，一些应用程序可能滥用相机权限来窃取用户的隐私。
因此，Android引入了权限系统，以使用户能够控制应用程序对其设备的访问权限。
当您首次打开一个应用程序并尝试使用相机时，您将被要求授予该应用程序相机权限。
您可以选择允许或拒绝该权限。
如果您选择拒绝相机权限，该应用程序将无法访问您的相机，并且您将无法使用该应用程序进行照片拍摄或视频录制。
请注意，您可以在稍后的时间更改权限设置。
如果您在以后决定授予相机权限，您可以按照以下步骤操作：1. 打开您的设备的设置应用程序。
2. 滚动并找到“应用程序”或“应用程序管理器”选项。
3. 在应用程序列表中找到您想要授予相机权限的应用程序。
4. 点击该应用程序以打开其详细信息页面。
5. 在详细信息页面中，找到“权限”选项。
6. 点击“权限”选项以查看该应用程序已经获得的权限。
7. 找到相机权限并启用它。
请记住，在授予权限之前，仔细考虑该应用程序是否真的需要相机权限。
如果您对应用程序或开发者不信任，或者担心他们会滥用您的相机权限，那么最好不要授予相机权限。
总而言之，相机权限是确保我们的设备安全和保护个人隐私的一项重要权限。
在使用Android设备的相机应用程序时，我们需要明智地管理相机权限，并只为可信任的应用程序授予权限。
这将确保我们的照片和视频只在受信任的环境中使用，并保护我们的个人信息免受滥用。
