我从字面上遵循了在android应用程序中实现GCM的示例,该应用程序使用以下代码接收消息:

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // Explicitly specify that GcmIntentService will handle the intent.
        ComponentName comp;
        comp = new ComponentName(context.getPackageName(), GcmIntentService.class.getName());
        // Start the service, keeping the device awake while it is launching.
        startWakefulService(context, (intent.setComponent(comp)));
        setResultCode(Activity.RESULT_OK);
    }
}


问题是GcmIntentService(公共类GcmIntentService扩展了IntentService)从未运行过吗?我是否缺少某些内容,或者通常应该触发onHandleIntent方法?

如有任何相关清单文件在下面,请先感谢:

最佳答案

我没有在清单中声明您的GcmIntentService服务。那可能是问题所在。

另外,下面一行

comp = new ComponentName(context.getPackageName(), GcmIntentService.class.getName());


假定GcmIntentService类位于应用的主程序包中(即其全名是com.diversivi.test.GcmIntentService)。如果不是这种情况,则广播接收器找不到服务类别。
