已经动态申请权限，但是还会遇到Permission Denial

[Yuelinghui]

在一个Activity的onCreate()里去动态申请权限，但是从Crash里还能找到Permission Denial

@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { String[] permissions = { Manifest.permission.CAMERA, Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE }; ArrayList permissionRequests = new ArrayList<>(); for (String permission : permissions) { if (PermissionChecker.checkSelfPermission(this, permission) != PermissionChecker.PERMISSION_GRANTED) { permissionRequests.add(permission); } } if (permissionRequests.size() > 0) { requestPermissions(permissionRequests.toArray(new String[]{}), REQUESTCODE); return; } } // 后续操作 }

@Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { super.onRequestPermissionsResult(requestCode, permissions, grantResults); if(REQUESTCODE == requestCode) { for (int grantResult : grantResults) { if (grantResult != PermissionChecker.PERMISSION_GRANTED) { // finish这个Activity return; } } //后续操作 } }

后续操作是读取用户的相册里的照片，然后自己展示出来，相当于自己做了一个自定义的相册

但是我们从Crash反馈中发现，还是会出现Permission Denial的错误，而且错误就是没有授予权限就去读取一个URI的错误。
