error at onHandleIntent cannot get receiver

Question

I need to call onHandleIntent and receive a value from app1 and get result in app2 without user notices ( different apps, one activity will call the servixe of other app). However, when onHandleIntent is starting in this line:

 mReceiver = workIntent.getParcelableExtra("receiver");

Brings the error

E/Parcel: Class not found when unmarshalling: com.example.idscomercial.myapplication.AddressResultReceiver
          java.lang.ClassNotFoundException: com.example.idscomercial.myapplication.AddressResultReceiver
             ...
           Caused by: java.lang.ClassNotFoundException: Didn't find class "com.example.idscomercial.myapplication.AddressResultReceiver" on path: DexPathList[[zip file "/data/app/com.veritran.vttokentest-2/base.apk"],nativeLibraryDirectories=[/data/app/com.veritran.vttokentest-2/lib/arm, /vendor/lib, /system/lib]]

I actually read :

https://stackoverflow.com/questions/28589509/android-e-parcel-class-not-found-when-unmarshalling-only-on-samsung-tab3

But still I cannot find the solution

This is the code:

App1

public class servicev extends IntentService {

    protected ResultReceiver mReceiver;

    public servicev() {
        super("yeah");
    }

    @Override
    protected void onHandleIntent(Intent workIntent) {
        Toast b = Toast.makeText(this.getApplicationContext(), "onHandle starting",  Toast.LENGTH_LONG    );
        b.show();
        Log.d("just", "tellme");
        String dataString = workIntent.getDataString();
        mReceiver = workIntent.getParcelableExtra("receiver");
       // mReceiver = new AddressResultReceiver(new Handler());

        deliverResultToReceiver(1,"value of servicev");
    }

    private void deliverResultToReceiver(int resultCode, String message) {
        Bundle bundle = new Bundle();
        bundle.putString("receiver", message);
        mReceiver.send(resultCode, bundle);
    }



}

App2:

public class MainActivity extends AppCompatActivity {

    protected ResultReceiver mResultReceiver;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        startIntentService();
        setContentView(R.layout.activity_main);
    }

    protected void startIntentService() {
        //Intent intent = new Intent();
        mResultReceiver = new AddressResultReceiver(new Handler());
        Intent intent=new Intent("com.veritran.vttokentest.servicev.START_SERVICE");


        intent.setPackage("com.veritran.vttokentest");
        //Intent intent = new Intent(this, FetchAddressIntentService.class);
        intent.putExtra("receiver", mResultReceiver);
        startService(intent);
    }




}

==> 2

public
class AddressResultReceiver extends ResultReceiver {

    public AddressResultReceiver(Handler handler) {
        super(handler);
    }

    @Override
    protected void onReceiveResult(int resultCode, Bundle resultData) {

        int duration = Toast.LENGTH_LONG;
        String mAddressOutput = resultData.getString("1");
        //Toast toast = Toast.makeText(context, "hi brow", duration);
        //toast.show();
        if (resultCode == 1) {



        }

    }
}

Answer 1

There could be a couple things going on here. First you are going to need a receiver to ever get information back from your service to the main activity. To create a receiver, make a new class that looks like this:

public class myReceiver extends ResultReceiver {
private Receiver mReceiver;

public myReceiver(Handler handler) {
    super(handler);
}

public void setReceiver(Receiver receiver) {
    mReceiver = receiver;
}

public interface Receiver {
    void onReceiveResult(int resultCode, Bundle resultData);
}

@Override
protected void onReceiveResult(int resultCode, Bundle resultData) {
    if (mReceiver != null) {
        mReceiver.onReceiveResult(resultCode, resultData);
    }
}

Then, in your main activity, create the receiver onCreate() with the following code:

mReceiver = new myReceiver(new Handler());
mReceiver.setReceiver(this);

This will be necessary to actually get any data back. you will also need to pass the receiver into the intent as an extra intent.putExtra("receiver", mReceiver); in the section where you define the intent. Then, in the IntentService, you can send your info back to the MainActivity with workIntent.getParcelableExtra("receiver").send(1, b) (where 1 is the result code you want and b is a Bundle of all the info you want to send back).

As far as why your service is never being called, I would check here to see if you are actually sending a correct intent to the service. You should also try removing the intent-filter from your service as it is unnecessary.

Generally you are not going to want to create a new MainActivity inside the service and use the receiver instead. Otherwise your service appears to be correct so I would make sure you check the intent that you are trying to pass in. If that still fails there are a number of other threads here about this problem.
