GCM 未在 android 4.0.4 设备上接收消息

GCM not receiving messages on android 4.0.4 device

我正在尝试让 GCM 在装有 android 4.0.4 的设备上运行。 首先,从设备发送到服务器到另一个设备是没有问题的,是接收部分不行。其次,我还在使用 android 5 的设备,在 phone 上一切正常。我认为这可能与设备有关,但我不确定 (MEDION p4013)。它是 android 4.0.4,因此您不需要 google 帐户即可运行,但可以肯定的是,我还在 phone 上激活了一个帐户,但仍然没有结果。

这是我的清单:

广播接收器:

        @Override
        public void onReceive(Context context, Intent intent) {
            ComponentName comp = new ComponentName(context.getPackageName(), GCMMessageHandler.class.getName());
            Log.d("received", "message");
            startWakefulService(context, intent.setComponent(comp));
            setResultCode(Activity.RESULT_OK);
        }

和处理程序:

private Handler handler;

public GCMMessageHandler() {
    super("GCMMessageHandler");
}

@Override
public void onCreate() {
    super.onCreate();
    handler = new Handler();
}

@Override
protected void onHandleIntent(Intent intent) {
    Bundle extras = intent.getExtras();
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
    String messageType = gcm.getMessageType(intent);
    final int challengeId = Integer.parseInt(extras.getString("challenge_id"));
    final String message = extras.getString("message");
    handler.post(new Runnable() {
        @Override
        public void run() {
            if(challengeId == -1) {
                Toast.makeText(getApplicationContext(), message, Toast.LENGTH_LONG).show();
            } else {
                //TODO implementatie
            }
        }
    });
    GCMBroadCastReceiver.completeWakefulIntent(intent);
}

好的,我找到了,

问题出在应用程序的 build.gradle 中。 applicationId 与应用程序的包名称不匹配。显然,对于 android 的旧版本,您会遇到问题,但对于新版本,它会自动将其更改为某处。
