我对 Android 开发不是很有经验，我会将 gcm 包含到现有应用程序中。到目前为止，我可以注册所有设备并收到registrationId。问题是，我从来没有在我的 Android 4.0 设备上输入 onMessage() 方法。我还使用 Galaxy Note 2 (Android 4.1) 进行了尝试，我可以在那里收到消息。我没有收到任何错误消息，我只是从不输入 onMessage()。

当我发送消息时，我总是得到一个 messageId，因此 gcm “接受”了该消息。但它永远不会交付给设备。

我怎样才能找出问题所在？？？提前致谢

GCMIntentService.java

public class GCMIntentService extends GCMBaseIntentService {

public GCMIntentService() {
    super("82........");
}

@Override
protected void onError(Context arg0, String error) {
    System.out.println("Not able to register or unregister because: "
            + error);

}

@Override
protected void onMessage(Context context, Intent intent) {

    String message = intent.getStringExtra("message");

    System.out.println("GCM DELIVERED MESSAGE TO DEVICE:" + message);
}

@Override
protected void onRegistered(Context arg0, String regId) {
    System.out.println("Device is registered  with RegisterId: " + regId);
}

@Override
protected void onUnregistered(Context arg0, String regId) {
    System.out.println("Device with RegisterId: " + regId
            + " has unregistered");
}

@Override
protected boolean onRecoverableError(Context context, String errorId) {
    System.out.println("Entered onRecoverableError");
    return super.onRecoverableError(context, errorId);
}
}

我的第一个活动 (Startup.java) 的 onCreate() 中的代码

GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);
final String regId = GCMRegistrar.getRegistrationId(this);

if (regId.equals("")) {
System.out.println("Id ist leer, Device wird neu registriert");
GCMRegistrar.register(this, "825134311331");
} else {
System.out.println("This device is already registered");
}

如果您通过 WIFI 尝试此操作，请确保端口 5228 没有被网络阻塞。这就是我解决这个问题的方法，我试图让它工作的时间比我想承认的要多。

确保 GCMIntentService 类位于清单中指定的包中
