android - GcmIntentService 中的 onHandleIntent 未被调用

Question

我正在关注来自 Android 开发人员的 GCM 演示。遇到以下情况。我在 GCMIntentService 中的 OnHandleIntent 没有被调用。有人可以帮忙吗？

package com.xyz.ads;


import com.google.android.gms.gcm.GoogleCloudMessaging;

import android.app.IntentService;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;

public class GcmIntentService extends IntentService {
    public GcmIntentService() {
        super("GcmIntentService");
        //super.onCreate();
        //super.onHandleIntent();
    }

    public void onCreate() {
        super.onCreate();

    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        super.onStartCommand(intent, startId, startId);
        Log.i("LocalService", "Received start id " + startId + ": " + intent);

        return START_STICKY;
    }
    public static final String TAG = "GCM Demo";

    @Override
    protected  void onHandleIntent(Intent intent) {
        Bundle extras = intent.getExtras();
        GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
        // The getMessageType() intent parameter must be the intent you received
        // in your BroadcastReceiver.
        String messageType = gcm.getMessageType(intent);

        // Release the wake lock provided by the WakefulBroadcastReceiver.
        GcmBroadcastReceiver.completeWakefulIntent(intent);
    }
}

这是我的 BroadCastReceiver

package com.xyz.ads;

import android.app.Activity;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.support.v4.content.WakefulBroadcastReceiver;


public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // Explicitly specify that GcmIntentService will handle the intent.
        ComponentName comp = new ComponentName(context.getPackageName(),GcmIntentService.class.getName());

        startWakefulService(context, (intent.setComponent(comp)));
        setResultCode(Activity.RESULT_OK);
    }
}

和我的 list

        </service>

    </application>

</manifest>

正在调用接收器内部的 onReceive 和 Intent 服务的构造函数..

我会说你在类(class)名称中缺少一个点。

<service
    android:name=".GcmIntentService"
    android:enabled="true" >
</service>

圆点代表您的应用程序包名称。
假设您的程序包名称是 com.example.app。然后写.GcmIntentService和写com.example.app.GcmIntentService效果一样。
