Android 6.0动态申请权限

Android 6.0动态申请权限

在android 6.0以下，开发者只需要在配置清单中说明，用户安装APP同意APP所申请的所有权限才能进行安装，而在android 6.0以上，开发者不仅要在配置清单中说明，对于一些危险权限还需要代码动态申请。这些危险权限在用户授权后才可以使用，比如调用摄像头、读取通讯录、定位等。

1. 需要动态申请的权限

以下为需要动态申请的权限，共有9组，每一组只有任何一个权限申请成功了，就默认整组的权限都可以使用。

group:android.permission-group.CONTACTS //通讯录

permission:android.permission.WRITE_CONTACTS //写入通讯录

permission:android.permission.GET_ACCOUNTS //访问GMail账户列表

permission:android.permission.READ_CONTACTS //读取通讯录

group:android.permission-group.PHONE //手机

permission:android.permission.READ_CALL_LOG //读取通话记录

permission:android.permission.READ_PHONE_STATE //读取电话状态

permission:android.permission.CALL_PHONE //拨打电话

permission:android.permission.WRITE_CALL_LOG //写入通话记录

permission:android.permission.USE_SIP //允许程序使用SIP视频服务

permission:android.permission.PROCESS_OUTGOING_CALLS //允许程序监视，修改或放弃播出电话

permission:com.android.voicemail.permission.ADD_VOICEMAIL//允许应用程序添加系统中的语音邮件。

group:android.permission-group.CALENDAR //系统日历

permission:android.permission.READ_CALENDAR //读取用户的日程信息

permission:android.permission.WRITE_CALENDAR //写入用户的日程信息

group:android.permission-group.CAMERA //摄像头

permission:android.permission.CAMERA //允许调用摄像头

group:android.permission-group.SENSORS //手机传感器

permission:android.permission.BODY_SENSORS//允许获取传感器数据

group:android.permission-group.LOCATION //定位权限

permission:android.permission.ACCESS_FINE_LOCATION //获取精准定位，通过GPS芯片

permission:android.permission.ACCESS_COARSE_LOCATION//通过wifi或基站获取粗略定位

group:android.permission-group.STORAGE //存储权限

permission:android.permission.READ_EXTERNAL_STORAGE //允许读取外部存储

permission:android.permission.WRITE_EXTERNAL_STORAGE //允许写入外部存储

group:android.permission-group.MICROPHONE //录音权限

permission:android.permission.RECORD_AUDIO //允许通过麦克风来录音

group:android.permission-group.SMS //短信权限

permission:android.permission.READ_SMS //允许读取短信

permission:android.permission.RECEIVE_WAP_PUSH//允许接收WAP PUSH信息

permission:android.permission.RECEIVE_MMS //允许接收彩信

permission:android.permission.RECEIVE_SMS //允许接收短信

permission:android.permission.SEND_SMS//允许发送短信

permission:android.permission.READ_CELL_BROADCASTS //获取小区广播

2. 危险权限申请步骤

2.1 在配置清单中添加所需要申请的权限

如 在配置清单中添加:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

2.2 申请权限步骤

2.2.1 检查权限

if (PackageManager.PERMISSION_GRANTED != PermissionChecker.checkCallingOrSelfPermission(context, Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
//没有授权
}else{
//已经授权过了
}

或者通过以下方式检查是否授权了

if (PackageManager.PERMISSION_GRANTED!=ContextCompat.checkSelfPermission(activity,
Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
//没有授权
}else{
//已经授权过了
}

2.2.2 请求权限申请

通过ActivityCompat.requestPermissions(final @NonNull Activity activity, final @NonNull String[] permissions, final @IntRange(from = 0) int requestCode) 方法申请权限，通过第二个参数可以看出一次可以申请多个权限。

2.2.3 申请权限回调

在Activity中重写如下函数

/**
*
* @param requestCode  请求码
* @param permissions 请求的权限数组
* @param grantResults 请求每个权限的状态:允许还是拒绝。对应于每个权限
*/
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == WRITE_PERMISSION_REQ_CODE){
for (int i = 0; i < grantResults.length; i++) {
if (grantResults[i] != PackageManager.PERMISSION_GRANTED){
//如果拒绝了
//改方法主要用于给用户一个申请权限的解释，该方法只有在用户在上一次已经拒绝过
//你的权限申请。
boolean isTip =ActivityCompat.shouldShowRequestPermissionRationale(this,permissions[i]);
if (isTip){
//表明用户没有彻底禁止弹出请求权限
}else {
//表面用户彻底禁止了弹出请求权限，可以提示用户然后跳到设置中打开权限
}

}else{
//允许了
}

}
}
}

通过在Activity中调用该类的某个静态方法来请求检测权限。如有需要可以重写 public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) ;方法来提示用户。
