Android6.0动态申请权限那些坑--以及避免用户选择不再提示后无法获取权限的问题

Android 6.0 为了保护用户隐私，将一些权限的申请放在了应用运行的时候去申请，比如以往的开发中，开发人员只需要将需要的权限在清单文件中配置即可，安装后用户可以在设置中的应用信息中看到：XX应用以获取****权限。用户点击可以选择给应用相应的权限。此前的应用权限用户可以选择允许、提醒和拒绝。在安装的时候用户是已经知道应用需要的权限的。但是这样存在一个问题，就是用户在安装的时候，应用需要的权限十分的多（有些开发者为了省事，会请求一些不必要的权限或者请求全部的权限），这个时候用户在安装应用的时候也许并没有发现某些侵犯自己隐私的权限请求，安装之后才发现自己的隐私数据被窃取。其实Android6.0 动态权限一方面是为了广大用户考虑，另一方面其实是Google为了避免一些不必要的官司。下面就说一下Android6.0对权限的分割：

这类权限需要在需要的时候，需要我们动态申请，比如：当我们需要打开相机拍摄照片的时候需要我们通过代码的方式在需要的地方去申请权限。Android6.0中权限问题中我们需要注意的是：

具体的权限分组情况如下表：

group:android.permission-group.CONTACTS

permission:android.permission.WRITE_CONTACTS

permission:android.permission.GET_ACCOUNTS

permission:android.permission.READ_CONTACTS

group:android.permission-group.PHONE

permission:android.permission.READ_CALL_LOG

permission:android.permission.READ_PHONE_STATE

permission:android.permission.CALL_PHONE

permission:android.permission.WRITE_CALL_LOG

permission:android.permission.USE_SIP

permission:android.permission.PROCESS_OUTGOING_CALLS

permission:com.android.voicemail.permission.ADD_VOICEMAIL

group:android.permission-group.CALENDAR

permission:android.permission.READ_CALENDAR

permission:android.permission.WRITE_CALENDAR

group:android.permission-group.CAMERA

permission:android.permission.CAMERA

group:android.permission-group.SENSORS

permission:android.permission.BODY_SENSORS

group:android.permission-group.LOCATION

permission:android.permission.ACCESS_FINE_LOCATION

permission:android.permission.ACCESS_COARSE_LOCATION

group:android.permission-group.STORAGE

permission:android.permission.READ_EXTERNAL_STORAGE

permission:android.permission.WRITE_EXTERNAL_STORAGE

group:android.permission-group.MICROPHONE

permission:android.permission.RECORD_AUDIO

group:android.permission-group.SMS

permission:android.permission.READ_SMS

permission:android.permission.RECEIVE_WAP_PUSH

permission:android.permission.RECEIVE_MMS

permission:android.permission.RECEIVE_SMS

permission:android.permission.SEND_SMS

permission:android.permission.READ_CELL_BROADCASTS

普通权限的总结：

ACCESS_LOCATION_EXTRA_COMMANDS 定位权限

ACCESS_NETWORK_STATE 网络状态权限

ACCESS_NOTIFICATION_POLICY 通知 APP通知显示在状态栏

ACCESS_WIFI_STATE WiFi状态权限

BLUETOOTH 使用蓝牙权限

BLUETOOTH_ADMIN 控制蓝牙开关

BROADCAST_STICKY 粘性广播

CHANGE_NETWORK_STATE 改变网络状态

CHANGE_WIFI_MULTICAST_STATE 改变WiFi多播状态，应该是控制手机热点（猜测）

CHANGE_WIFI_STATE 控制WiFi开关，改变WiFi状态

DISABLE_KEYGUARD 改变键盘为不可用

EXPAND_STATUS_BAR 扩展bar的状态

GET_PACKAGE_SIZE 获取应用安装包大小

INTERNET 网络权限

KILL_BACKGROUND_PROCESSES 杀死后台进程

MODIFY_AUDIO_SETTINGS 改变音频输出设置

NFC 支付

READ_SYNC_SETTINGS 获取手机设置信息

READ_SYNC_STATS 数据统计

RECEIVE_BOOT_COMPLETED 监听启动广播

REORDER_TASKS 创建新栈

REQUEST_INSTALL_PACKAGES 安装应用程序

SET_TIME_ZONE 允许应用程序设置系统时间区域

SET_WALLPAPER 设置壁纸

SET_WALLPAPER_HINTS 设置壁纸上的提示信息，个性化语言

TRANSMIT_IR 红外发射

USE_FINGERPRINT 指纹识别

VIBRATE 震动

WAKE_LOCK 锁屏

WRITE_SYNC_SETTINGS 改变设置

SET_ALARM 设置警告提示

INSTALL_SHORTCUT 创建快捷方式

UNINSTALL_SHORTCUT 删除快捷方式

以上这些只是普通权限，我们开发的时候，正常使用就行了，需要的权限在清单文件配置即可。

申请步骤

1. 将targetSdkVersion设置为23，注意，如果你将targetSdkVersion设置为>=23，则必须按照Android谷歌的要求，动态的申请权限，如果你暂时不打算支持动态权限申请，则targetSdkVersion最大只能设置为22.
2 在AndroidManifest.xml中申请你需要的权限，包括普通权限和需要申请的特殊权限。
3.开始申请权限，此处分为3部。
- （1）检查是否由此权限checkSelfPermission()，如果已经开启，则直接做你想做的。
- （2）如果未开启，则判断是否需要向用户解释为何申请权限shouldShowRequestPermissionRationale。
- （3）如果需要（即返回true），则可以弹出对话框提示用户申请权限原因，用户确认后申请权限requestPermissions()，如果不需要（即返回false），则直接申请权限requestPermissions()。

单个权限申请.png

/**

* Requests permission.

*

* @param activity

* @param requestCode request code, e.g. if you need request CAMERA permission,parameters is PermissionUtils.CODE_CAMERA

*/

public static void requestPermission(final Activity activity, final int requestCode, PermissionGrant permissionGrant) {

if (activity == null) {

return;

}

Log.i(TAG, "requestPermission requestCode:" + requestCode);

if (requestCode < 0 || requestCode >= requestPermissions.length) {

Log.w(TAG, "requestPermission illegal requestCode:" + requestCode);

return;

}

final String requestPermission = requestPermissions[requestCode];

//如果是6.0以下的手机，ActivityCompat.checkSelfPermission()会始终等于PERMISSION_GRANTED，

// 但是，如果用户关闭了你申请的权限(如下图，在安装的时候，将一些权限关闭了)，ActivityCompat.checkSelfPermission()则可能会导致程序崩溃(java.lang.RuntimeException: Unknown exception code: 1 msg null)，

// 你可以使用try{}catch(){},处理异常，也可以判断系统版本，低于23就不申请权限，直接做你想做的。permissionGrant.onPermissionGranted(requestCode);

// if (Build.VERSION.SDK_INT < 23) {

// permissionGrant.onPermissionGranted(requestCode);

// return;

// }

int checkSelfPermission;

try {

checkSelfPermission = ActivityCompat.checkSelfPermission(activity, requestPermission);

} catch (RuntimeException e) {

Toast.makeText(activity, "please open this permission", Toast.LENGTH_SHORT)

.show();

Log.e(TAG, "RuntimeException:" + e.getMessage());

return;

}

if (checkSelfPermission != PackageManager.PERMISSION_GRANTED) {

Log.i(TAG, "ActivityCompat.checkSelfPermission != PackageManager.PERMISSION_GRANTED");

if (ActivityCompat.shouldShowRequestPermissionRationale(activity, requestPermission)) {

Log.i(TAG, "requestPermission shouldShowRequestPermissionRationale");

shouldShowRationale(activity, requestCode, requestPermission);

} else {

Log.d(TAG, "requestCameraPermission else");

ActivityCompat.requestPermissions(activity, new String[]{requestPermission}, requestCode);

}

} else {

Log.d(TAG, "ActivityCompat.checkSelfPermission ==== PackageManager.PERMISSION_GRANTED");

Toast.makeText(activity, "opened:" + requestPermissions[requestCode], Toast.LENGTH_SHORT).show();

//得到权限的时候，就可以在回调里面做你想做的事情了

permissionGrant.onPermissionGranted(requestCode);

}

备注！！！

（1）checkSelfPermission：检查是否拥有这个权限

（2）requestPermissions：请求权限，一般会弹出一个系统对话框，询问用户是否开启这个权限。

（3）shouldShowRequestPermissionRationale：Android原生系统中，如果第二次弹出权限申请的对话框，会出现“以后不再弹出”的提示框，如果用户勾选了，你再申请权限，则shouldShowRequestPermissionRationale返回true，意思是说要给用户一个解释，告诉用户为什么要这个权限。然而，在实际开发中，需要注意的是，很多手机对原生系统做了修改，比如小米，小米4的6.0的shouldShowRequestPermissionRationale 就一直返回false，而且在申请权限时，如果用户选择了拒绝，则不会再弹出对话框了。。。。所以说这个地方有坑，我的解决方法是，在回调里面处理，如果用户拒绝了这个权限，则打开本应用信息界面，由用户自己手动开启这个权限。

（4）每个应用都有自己的权限管理界面，里面有本应用申请的权限以及各种状态，即使用户已经同意了你申请的权限，他也随时可以关闭

注意事项

API问题

由于checkSelfPermission和requestPermissions从API 23才加入，低于23版本，需要在运行时判断或者使用Support Library v4中提供的方法

ContextCompat.checkSelfPermission
ActivityCompat.requestPermissions
ActivityCompat.shouldShowRequestPermissionRationale

多系统问题

当我们支持了6.0必须也要支持4.4，5.0这些系统，所以需要在很多情况下，需要有两套处理。比如Camera权限

[java] copy ?

if
{

两个特殊权限

特殊权限，顾名思义，就是一些特别敏感的权限，在Android系统中，主要由两个

SYSTEM_ALERT_WINDOW，设置悬浮窗，进行一些黑科技
WRITE_SETTINGS 修改系统设置

关于上面两个特殊权限的授权，做法是使用startActivityForResult启动授权界面来完成。

请求SYSTEM_ALERT_WINDOW

[java] copy ?

private REQUEST_CODE = ;
private requestAlertWindowPermission() {
Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION);
+ getPackageName()));
@Overrideprotected onActivityResult( requestCode, resultCode, Intent data) {
.onActivityResult(requestCode, resultCode, data);
(requestCode == REQUEST_CODE) {
(Settings.canDrawOverlays()) {

上述代码需要注意的是

使用Action Settings.ACTION_MANAGE_OVERLAY_PERMISSION启动隐式Intent
使用"package:" + getPackageName()携带App的包名信息
使用Settings.canDrawOverlays方法判断授权结果

请求WRITE_SETTINGS

[java] copy ?

private REQUEST_CODE_WRITE_SETTINGS = ;
private requestWriteSettings() {
Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS);
+ getPackageName()));
@Overrideprotected onActivityResult( requestCode, resultCode, Intent data) {
.onActivityResult(requestCode, resultCode, data);
(requestCode == REQUEST_CODE_WRITE_SETTINGS) {
(Settings.System.canWrite()) {

上述代码需要注意的是

使用Action Settings.ACTION_MANAGE_WRITE_SETTINGS 启动隐式Intent
使用"package:" + getPackageName()携带App的包名信息
使用Settings.System.canWrite方法检测授权结果

注意：关于这两个特殊权限，一般不建议应用申请。
