是否需要在运行 Android Lollipop 或更低版本的设备上检查系统权限？

Question

If I want to check whether for example the permission to Modify System Settings is granted or not, is there any case where it's necessary below API 23? I have this code that checks whether the permission is granted on older Android versions and I was wondering if there's any scenario where it's needed:

public void checkWritePermission() {
    if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.WRITE_SETTINGS) == PackageManager.PERMISSION_DENIED) {
        try {
            ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.WRITE_SETTINGS}, 4);
        } catch (ActivityNotFoundException activityNotFound) {
            Toast.makeText(getApplicationContext(), R.string.cant_find_system_settings, Toast.LENGTH_LONG).show();
            closeApp();
        }
    }
}

You don't need to have a permission check for the lower versions.
