我确实按照在Android应用程序中实现GCM的示例,应用程序正在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IntentService )永远不会被运行?我是否遗漏了某些内容,或者它是否应该触发 onHandleIntent 方法?
如果有任何相关的Manifest文件,请提前感谢:

我没有在清单中看到您的GcmIntentService
服务已声明。这可能是问题所在。
另外,以下一行
comp = new ComponentName(context.getPackageName(), GcmIntentService.class.getName());
假设GcmIntentService
类位于您应用的主程序包中(即其全名为com.diversivi.test.GcmIntentService
)。如果不是这样,广播接收器就找不到服务等级。
