检查是否开了 权限和跳到该应用的设置中

一 检查是否开了权限，例如定位权限

private static final String EXTERNAL_STORAGE_PERMISSION = "android.permission.ACCESS_FINE_LOCATION";
private static boolean hasExternalStoragePermission(Context context) {
        int perm = context.checkCallingOrSelfPermission(ACCESS_FINE_LOCATION);
        return perm == PackageManager.PERMISSION_GRANTED;
    }

其中android.permission.ACCESS_FINE_LOCATION是定位权限。
要先检查其它权限，只需要把ACCESS_FINE_LOCATION改为对于的权限就可以了。

二跳到应用的设置

Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
Uri uri = Uri.fromParts("package", getPackageName(), null);
intent.setData(uri);
startActivity(intent);
