android - 从Wear向手机发送消息时无法接收消息

我想从穿戴设备向Android手机发送消息，穿戴设备中的“ SendMessageResult”是成功的，但不会触发我的手机上的“ showToast”方法，有人可以帮我了解我在做什么？

这是我的穿衣清单

手机的MainActivity .java

package com.example.user.wear2;

import android.content.Intent;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.wearable.Wearable;

public class MainActivity extends AppCompatActivity  implements    GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener{
private GoogleApiClient mGoogleApiClient;
private static final String TAG = MainActivity.class.getSimpleName();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Wearable.API)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .build();
    mGoogleApiClient.connect();
}
@Override
public void onConnected(@Nullable Bundle bundle) {
    Log.d(TAG,"onConnected");
}

@Override
public void onConnectionSuspended(int i) {
    Log.d(TAG,"onConnectionSuspended");
}

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

这是Lisswear.java，我在移动设备中的WearableListenerService

package com.example.user.wear2;

import android.util.Log;
import android.widget.Toast;

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

public class Lisswear extends WearableListenerService {
@Override
public void onMessageReceived(MessageEvent messageEvent) {
    //if(messageEvent.getPath().equals("/showToast")) {
    showToast(messageEvent.getPath());
    //}
}


private void showToast(String message) {
    Toast.makeText(this, message, Toast.LENGTH_LONG).show();
}
}

最佳答案

您可以尝试以下操作：


确保两个设备上的applicationid都与此SO thread中的情况相同
确保您使用相同的包裹名称
确保您有enabled permissions
您还可以在文档中从可穿戴设备到设备阅读有关Sending and Receiving Messages的更多信息。
