[英]GcmListenerService client side notification
I am trying to use gcm to push notifications on android devices. 我正在尝试使用gcm在Android设备上推送通知。 So far I have registered with gcm and sent my back-end the necessary information to make a post request to the gcm severs which builds a 200 response. 到目前为止,我已经向gcm注册,并向后端发送了必要的信息,以便向gcm服务器发送发布请求,从而建立200个响应。 All the steps have come together except the client side receiving the message. 除了客户端收到消息外,所有步骤都已合并完成。 I don't get the message. 我没有收到消息。 Displayed here is my gcm listener class: 这里显示的是我的gcm侦听器类:
import com.google.android.gms.gcm.GcmListenerService;
public class MyGcmListenerService extends GcmListenerService {
public static final int MESSAGE_NOTIFICATION_ID = 435345;
private static final String TAG = "MyGcmListenerService";
@Override
public void onMessageReceived(String from, Bundle data) {
String message = data.getString("message");
Log.d(TAG, "From: " + from);
Log.d(TAG, "Message: " + message);
sendNotification(from,message);
}
private void sendNotification(String title, String body) {
Context context = getBaseContext();
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.mipmap.ic_launcher).setContentTitle(title)
.setContentText(body);
NotificationManager mNotificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(MESSAGE_NOTIFICATION_ID, mBuilder.build());
}
}

Actually looking at this further it looks like you haven't setup the receiver correctly. 实际上,进一步看似乎您没有正确设置接收器。 Seems you need to include at least. 似乎您至少需要包括在内。
<service
android:name="com.example.MyGcmListenerService "
android:exported="false" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
</intent-filter>
</service>
And for the rest just follow that link. 对于其余的,只需单击该链接。
You have to put your resgistration intent service at the end of yout Manifest file. 您必须将注册意向服务放在清单文件的末尾。 Like this example: 像这个例子:
<service
android:name="com.example.gcm.RegistrationIntentService"
android:exported="false">
</service>
Hope that help you, more information, you can visit this link and you can view an example of RegistrationIntentService here . 希望对您有帮助,更多信息,您可以访问此链接,并可以在此处查看RegistrationIntentService的示例。
