有没有什么方法可以识别用户授予了哪些位置权限

Question

有没有什么方法可以识别用户在 Android 中以编程方式授予了哪个位置权限。

如下所示

• 使用应用程序时
• 仅这一次
• 拒绝

我想从另一个应用程序了解特定应用程序的当前位置权限状态。不是为了检查其运行时间。

Answer 1

是的，我们可以使用权限组合以编程方式检查它。我根据android版本创建了该方法：

 private void checkLocationPermissionState(Context context){

    int fineLocation = ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_FINE_LOCATION);
    int coarseLocation = ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_COARSE_LOCATION);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {

        int bgLocation = ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_BACKGROUND_LOCATION);

        boolean isAppLocationPermissionGranted = (bgLocation == PackageManager.PERMISSION_GRANTED) &&
                (coarseLocation == PackageManager.PERMISSION_GRANTED);

        boolean preciseLocationAllowed = (fineLocation == PackageManager.PERMISSION_GRANTED)
                && (coarseLocation == PackageManager.PERMISSION_GRANTED);

        if (preciseLocationAllowed) {
            Log.e("PERMISSION","Precise location is enabled in Android 12");
        } else {
            Log.e("PERMISSION","Precise location is disabled in Android 12");
        }

        if (isAppLocationPermissionGranted) {
            Log.e("PERMISSION","Location is allowed all the time");
        } else if(coarseLocation == PackageManager.PERMISSION_GRANTED){
            Log.e("PERMISSION","Location is allowed while using the app");
        }else{
            Log.e("PERMISSION","Location is not allowed.");
        }

    } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {

        int bgLocation = ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_BACKGROUND_LOCATION);

        boolean isAppLocationPermissionGranted = (bgLocation == PackageManager.PERMISSION_GRANTED) &&
                (coarseLocation == PackageManager.PERMISSION_GRANTED);

        if (isAppLocationPermissionGranted) {
            Log.e("PERMISSION","Location is allowed all the time");
        } else if(coarseLocation == PackageManager.PERMISSION_GRANTED){
            Log.e("PERMISSION","Location is allowed while using the app");
        }else{
            Log.e("PERMISSION","Location is not allowed.");
        }
        
    } else {

        boolean isAppLocationPermissionGranted = (fineLocation == PackageManager.PERMISSION_GRANTED) &&
                (coarseLocation == PackageManager.PERMISSION_GRANTED);

        if (isAppLocationPermissionGranted) {
            Log.e("PERMISSION","Location permission is granted");
        } else {
            Log.e("PERMISSION","Location permission is not granted");
        }
    }


}
