Daten von Android Wear zur Handy-App senden geht nicht

Hallo Leute,

ich versuche jetzt seit ein paar Stunden Daten von meiner Android Wear-App an die dazugehörige Android-App zu senden. Allerdings kommt bei der Android App nichts an.

Android Phone App:

AndroidManifest.xml:

Code:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="sh.evolutio.car">

    <uses-feature
        android:name="android.software.leanback"
        android:required="true" />

    <application
        android:allowBackup="false"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

        <service android:name=".services.ListenerService" >
            <intent-filter>
                <action android:name="com.google.android.gms.wearable.MESSAGE_RECEIVED" />
                <action android:name="com.google.android.gms.wearable.DATA_CHANGED" />
                <!-- <data android:scheme="wear" android:host="*" android:pathPrefix="/updatecar" /> -->
            </intent-filter>
        </service>

        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
                <category android:name="android.intent.category.LEANBACK_LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

mein ListenerService.java

Code:

package sh.evolutio.car.services;

import android.content.Intent;
import android.util.Log;

import com.google.android.gms.wearable.MessageEvent;
import com.google.android.gms.wearable.WearableListenerService;

public class ListenerService extends WearableListenerService {
  private static final String TAG = "ListenerService";
  private static final String MESSAGE_PATH = "/updatecar";

  @Override
  public void onCreate() {
      Log.d(TAG, "ListenerService created");
  }

  @Override
  public void onMessageReceived(MessageEvent messageEvent) {
      Log.d(TAG, "onMessageReceived");

      if (messageEvent.getPath().equals(MESSAGE_PATH)) {
          Log.d(TAG, "good message");
      } else {
          Log.d(TAG, "bad message");
      }
  }
}

der dazugehörige Code aus meiner MainActivity:

Code:

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
  setSupportActionBar(toolbar);

  startService(new Intent(MainActivity.this, ListenerService.class));
}

Nachdem starten der App erscheint in der Logcat für das Handy folgende Meldung:

Code:

26131-26131/sh.evolutio.car D/ListenerService: ListenerService created

Also scheint der ListenerService zu laufen.

Jetzt zu der Android Wear App:

AndroidManifest.xml:

Code:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="sh.evolutio.carwear">

  <uses-feature android:name="android.hardware.type.watch" />

  <uses-permission android:name="android.permission.WAKE_LOCK" />

  <application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@android:style/Theme.DeviceDefault">
    <uses-library
      android:name="com.google.android.wearable"
      android:required="true" />
    <meta-data
      android:name="com.google.android.wearable.standalone"
      android:value="false" />

    <activity
      android:name=".MainActivity"
      android:label="@string/app_name">
      <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
    </activity>
  </application>
</manifest>

Hier die MainActivity:

Code:

package sh.evolutio.carwear;

import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.wearable.activity.WearableActivity;
import android.util.Log;
import android.view.View;

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.common.api.ResultCallback;
import com.google.android.gms.tasks.OnFailureListener;
import com.google.android.gms.tasks.OnSuccessListener;
import com.google.android.gms.tasks.Task;
import com.google.android.gms.wearable.MessageApi;
import com.google.android.gms.wearable.Node;
import com.google.android.gms.wearable.NodeApi;
import com.google.android.gms.wearable.Wearable;

public class MainActivity extends WearableActivity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {
  private static String TAG = "MainActivity";
  private static final String MESSAGE_PATH = "/updatecar";

  Node mNode; // the connected device to send the message to
  GoogleApiClient mGoogleApiClient;
  private boolean mResolvingError = false;

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

    //Connect the GoogleApiClient
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Wearable.API)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .build();

    sendMessage("test");

    // Enables Always-on
    setAmbientEnabled();
  }

  @Override
  protected void onStart() {
    super.onStart();
    if (!mResolvingError) {
      mGoogleApiClient.connect();
    }
  }

  /**
    * Resolve the node = the connected device to send the message to
    */
  private void resolveNode() {
    Log.d(TAG, "resolveNode");

    Wearable.NodeApi.getConnectedNodes(mGoogleApiClient)
      .setResultCallback(new ResultCallback<NodeApi.GetConnectedNodesResult>() {
        @Override
        public void onResult(NodeApi.GetConnectedNodesResult nodes) {
          for (Node node : nodes.getNodes()) {
            Log.d(TAG, "resolvedNode: " + node);
            mNode = node;
          }
        }
      });
  }

  @Override
  public void onConnected(Bundle bundle) {
    resolveNode();
  }

  @Override
  public void onConnectionSuspended(int i) {}

  @Override
  public void onConnectionFailed(ConnectionResult connectionResult) {
    Log.d(TAG, "connectionResult: " + connectionResult);
  }

  /**
    * Send message to mobile handheld
    */
  private void sendMessage(String Key) {
    if (mNode != null && mGoogleApiClient!= null && mGoogleApiClient.isConnected()) {
      final String messageKey = Key;

      Log.d(TAG, "isConnected: " + mGoogleApiClient.isConnected());
      Log.d(TAG, "connected to: " + mNode.getId());

      Task<Integer> sendTask = Wearable.getMessageClient(MainActivity.this).sendMessage(mNode.getId(), MESSAGE_PATH, messageKey.getBytes());
      sendTask.addOnSuccessListener(new OnSuccessListener<Integer>() {
        @Override
        public void onSuccess(Integer integer) {
          Log.d(TAG, "onSuccess: " + integer);
        }
      });

      sendTask.addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
          Log.d(TAG, "onFailure: " + e.getMessage());
        }
      });

      Wearable.MessageApi.sendMessage(mGoogleApiClient, mNode.getId(), MESSAGE_PATH, messageKey.getBytes()).setResultCallback(
        new ResultCallback<MessageApi.SendMessageResult>() {
          @Override
          public void onResult(@NonNull MessageApi.SendMessageResult sendMessageResult) {
            if (sendMessageResult.getStatus().isSuccess()) {
              Log.v(TAG, "Message: { " + messageKey + " } sent to: " + mNode.getDisplayName());
            } else {
              // Log an error
              Log.v(TAG, "ERROR: failed to send Message");
            }
          }
        }
      );
    }
  }
}

Und wenn ich dann die Android Wear App starte, steht in der Logcat zu meiner Uhr folgendes:

Code:

sh.evolutio.carwear D/MainActivity: isConnected: true
sh.evolutio.carwear D/MainActivity: connected to: 778d0d53
sh.evolutio.carwear V/MainActivity: Message: { test } sent to: HUAWEI Mate 10 Pro
sh.evolutio.carwear D/MainActivity: onSuccess: 17282

So, damit wurde also der String "test" erfolgreich an mein Handy geschickt, allerdings kommt da nichts an..

Irgendwo hatte ich gelesen, dass die Packagenames der AndroidManifests gleich sein müssen?
Muss ich also in beiden AndroidManifests

Code:

package="sh.evolutio.car"

nehmen?
