android 6.0 内部SD卡权限管理的方法

android 6.0以后，权限的管理方法就不仅局限于androidManifest.xml了，APK 如果需要权限，必须要在代码里实现权限的申请。

下面是实时查看权限的许可情况和实时撤销权限许可的命令（不用每次都去: 设置->应用->xxx应用->应用信息->权限->权限列表，修改权限的许可）的方法

Use the adb tool to manage permissions from the command line:
List permissions and status by group: 这个只是列出设备的所有的危险权限，并没有命令来显示某个应用的权限的许可情况（这点不好）

$ adb shell pm list permissions -d -g

Grant or revoke one or more permissions:

$ adb shell pm [grant|revoke] <permission-name> ...

Analyze your app for services that use permissions.

查看内部SD权限的读取权限

group:android.permission-group.STORAGE

  permission:android.permission.READ_EXTERNAL_STORAGE

  permission:android.permission.WRITE_EXTERNAL_STORAGE

权限的申请判断代码如下：

/***
group:android.permission-group.STORAGE
permission:android.permission.READ_EXTERNAL_STORAGE
permission:android.permission.WRITE_EXTERNAL_STORAGE
***/
private static final int REQUEST_EXTERNAL_STORAGE = 1;
private static String[] PERMISSIONS_STORAGE = {
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.WRITE_EXTERNAL_STORAGE };
private boolean verifyStoragePermissions(Activity activity) {

if(Util.SDK_INT < 23) /*******below android 6.0*******/
{
return true;
}

// Check if we have write permission
int permission = ActivityCompat.checkSelfPermission(activity,
Manifest.permission.READ_EXTERNAL_STORAGE);
if (permission != PackageManager.PERMISSION_GRANTED) {
// We don't have permission so prompt the user
ActivityCompat.requestPermissions(activity,PERMISSIONS_STORAGE,
REQUEST_EXTERNAL_STORAGE);
return false;
}
else
{
return true;
}
}

如果verifyStoragePermissions 返回时false，那么需要实现权限的申请处理，实现onRequestPermissionResult

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case REQUEST_EXTERNAL_STORAGE: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
/×××do request function(into apk)×××××/
} else {

Toast.makeText(getApplicationContext(),
"storage permission denied,it will exit apk",
Toast.LENGTH_LONG).show();

/×××do request function(exitapk)×××××/
finish();
}
}
break;
default:
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
break;
}
}
}


如果verifyStoragePermissions返回true则直接进入APK或Activity.
