我必须以编程方式从android应用程序的manifest.xml中检索权限组
我想以组方式列出设备上安装的每个应用程序所采用的权限。
请看这个，我希望这会对你有所帮助。
private static final int REQUEST_PERMISSIONS = 10; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); if (Build.VERSION.SDK_INT >=23) { getPermission(); } else { initView(); } } private void initView() { setContentView(R.layout.activity_main); ... .. } @TargetApi(Build.VERSION_CODES.M) private void getPermission() { if (ContextCompat.checkSelfPermission(StartActivity.this, Manifest.permission.CAMERA) + ContextCompat.checkSelfPermission(StartActivity.this, Manifest.permission.RECORD_AUDIO) != PackageManager.PERMISSION_GRANTED) { Log.i("Permission is require first time", "...OK...getPermission() method!..if"); ActivityCompat.requestPermissions(StartActivity.this, new String[]{Manifest.permission.CAMERA, Manifest.permission.RECORD_AUDIO}, REQUEST_PERMISSIONS); } else { initView(); } } @Override public void onRequestPermissionsResult(final int requestCode, @NonNull final String[] permissions, @NonNull final int[] grantResults) { super.onRequestPermissionsResult(requestCode, permissions, grantResults); if (requestCode == REQUEST_PERMISSIONS) { if ((grantResults.length > 0) && (grantResults[0]+grantResults[1]) == PackageManager.PERMISSION_GRANTED) { // Permission granted. initView(); } else { Toast.makeText(StartActivity.this, "All Permission is Required, Toast.LENGTH_LONG).show(); getPermission() } } } 您可以使用PackageManager检索应用程序的权限。 请参阅： 应用列表权限
