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);
