所有权限都没有在android marshmallow中被授​​予

Question

我正在努力为我的Android设备提供运行时权限。在我的情况下，一旦用户点击“呼叫”按钮，它就应该要求3个权限CALL_PHONE，CAMERA和RECORD_AUDIO。 它要求我可以在日志中看到的权限，但只授予了一个权限。再次，如果我杀了我的应用程序，然后点击“呼叫”按钮，则会询问第二个权限，并且nxt时间为一个。所有3个都没有被同时询问。正如我在日志中看到的那样，它仅在第一次询问并授予所有权限，但一次只能询问一次。

 @JavascriptInterface
    public void askPermission(String permission){
        Log.d("Ask permission", permission);
        switch (permission){
        case "audioCall":
            askForPermission(Manifest.permission.CALL_PHONE,CALL_PHONE);
            askForPermission(Manifest.permission.CAMERA,CAMERA);
            askForPermission(Manifest.permission.RECORD_AUDIO,RECORD_AUDIO);
            break;
        case "videoCall":
            askForPermission(Manifest.permission.CALL_PHONE,CALL_PHONE);
            askForPermission(Manifest.permission.CAMERA,CAMERA);
            askForPermission(Manifest.permission.RECORD_AUDIO,RECORD_AUDIO);
            break;

        case "writeExternalStorage":
            askForPermission(Manifest.permission.CALL_PHONE,CALL_PHONE);
            askForPermission(Manifest.permission.CAMERA,CAMERA);
            askForPermission(Manifest.permission.RECORD_AUDIO,RECORD_AUDIO);
            break;

        case "WRITE_EXTERNAL_STORAGE":
            askForPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE,WRITE_EXTERNAL_STORAGE);
            break;

        case "GET_ACCOUNTS":
            askForPermission(Manifest.permission.GET_ACCOUNTS,GET_ACCOUNTS);
            break;

        case "READ_CONTACTS":
            askForPermission(Manifest.permission.READ_CONTACTS,READ_CONTACTS);
            break;

        }
    }

public void askForPermission(String permission, Integer requestCode){
    Log.d("Permissions requested is+", permission);

    if (ContextCompat.checkSelfPermission(MainActivity.this, permission) != PackageManager.PERMISSION_GRANTED) {

        // Should we show an explanation?
        if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this, permission)) {
            Log.d("Permission is already granted", ""+permission);
            //This is called if user has denied the permission before
            //In this case I am just asking the permission again
            ActivityCompat.requestPermissions(MainActivity.this, new String[]{permission}, requestCode);

        } else {
            Log.d("asking for permissions", ""+permission);
            ActivityCompat.requestPermissions(MainActivity.this, new String[]{permission}, requestCode);
        }
    } else {
        /* Toast.makeText(this, "" + permission + " is already granted.", Toast.LENGTH_SHORT).show();*/
        Log.d("Permission is already granted", ""+permission);
    }
}

设法覆盖此方法，它将处理结果。

@Override
    public void onRequestPermissionsResult(int requestCode,
            String permissions[], int[] grantResults) {
        switch (requestCode) {
            case MY_PERMISSIONS_REQUEST_READ_CONTACTS: {
                // If request is cancelled, the result arrays are empty.
                if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                    // permission was granted, yay! Do the
                    // contacts-related task you need to do.

                } else {

                    // permission denied, boo! Disable the
                    // functionality that depends on this permission.
                }
                return;
            }

            // other 'case' lines to check for other
            // permissions this app might request
        }
    }
