我遇到GCM问题。 我创建了一个服务器端通知推送器(在PHP中),它发送给具有该应用程序的特定用户(基于位置),通知。
我有三个用于管理注册和通知监听器的课程。
public class PusherIDListenerService extends InstanceIDListenerService {
private static final String TAG = "PUSHER_ID_LISTENER_SERVICE";
@Override
public void onTokenRefresh() {
Intent intent = new Intent(this, RegistrationIntentService.class);
startService(intent);
}
}
现在是注册类
public class RegistrationIntentService extends IntentService {
private static final String TAG = "REGISTRATION_SERVICE";
private int idClient;
public RegistrationIntentService() {
super(TAG);
}
@Override
protected void onHandleIntent(Intent intent) {
this.idClient = intent.getIntExtra("idClient", 0);
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
String locationProvider = LocationManager.NETWORK_PROVIDER;
Location lastKnownLocation = locationManager.getLastKnownLocation(locationProvider);
double lat = 0;
double lon = 0;
if (lastKnownLocation != null) {
lat = lastKnownLocation.getLatitude();
lon = lastKnownLocation.getLongitude();
} else {
Log.d(TAG, "Position not available, updating next time.");
}
try {
synchronized (TAG) {
InstanceID instanceID = InstanceID.getInstance(this);
String senderId = getString(R.string.gcm_defaultSenderId);
String token = instanceID.getToken(senderId, GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
this.sendRegistrationToServer(token, lat, lon);
}
} catch (Exception e) {
Log.d(TAG, "Failed to complete token refresh", e);
}
Intent registrationComplete = new Intent(this, ActStartPage.class);
LocalBroadcastManager.getInstance(this).sendBroadcast(registrationComplete);
}
private void sendRegistrationToServer(String token, double lat, double lon) {
// doing some stuff
}
}
现在是听众
public class PusherListenerService extends GcmListenerService {
private static final String TAG = "PUSHER_LISTENER_SERVICE";
@Override
public void onMessageReceived(String from, Bundle data) {
String title = data.getString("title");
String message = data.getString("body");
Log.d(TAG, "From: " + from);
Log.d(TAG, "Message: " + message);
sendNotification(title, message);
}
private void sendNotification(String title, String message) {
Intent intent = new Intent(this, ActStartPage.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("menuTabId", 3);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle(title)
.setContentText(message)
.setAutoCancel(true)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancelAll();
notificationManager.notify((int)(Math.random()), notificationBuilder.build());
}
}
我的清单看起来像这样
<receiver
android:name="com.google.android.gms.gcm.GcmReceiver"
android:exported="true"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
</intent-filter>
</receiver>
<service
android:name="clab.kalitys.mobile.CoreModuleManager.Pusher.PusherListenerService"
android:exported="false" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
</intent-filter>
</service>
<service
android:name="clab.kalitys.mobile.CoreModuleManager.Pusher.PusherIDListenerService"
android:exported="false">
<intent-filter>
<action android:name="com.google.android.gms.iid.InstanceID"/>
</intent-filter>
</service>
<service
android:name="clab.kalitys.mobile.CoreModuleManager.Pusher.RegistrationIntentService"
android:exported="false">
</service>
最后,我在onCreate的主要活动中启动了所有这些
if (checkPlayServices()) {
Intent intent = new Intent(this, RegistrationIntentService.class);
intent.putExtra("idClient", Integer.parseInt(this.getResources().getString(R.string.clientId)));
startService(intent);
}
现在,有效的是:
什么不起作用=(:
我尝试了一些东西,但没有任何效果。我也不太了解xml设置。
以下是我发送给gcm的JSON示例:
"notification":{
"body":"blabla",
"title":"one title"
"icon":"notification_icon"
},
"data":{
"body":"blabla",
"title":"one title"
},
"registration_ids":["id1", "id2", etc]
当我在应用关闭时收到通知时,我的代码(或我必须添加的内容)再次启动应用程序有什么问题?
有什么想法吗?
谢谢=)
答案 0 :(得分:1)
好的,
我刚解决了这个问题。
我发送的JSON就像:
"notification":{
"body":"blabla",
"title":"one title"
"icon":"notification_icon"
},
"data":{
"body":"blabla",
"title":"one title"
},
"registration_ids":["id1", "id2", etc]
但是这部分(来自JSON):
"notification":{
"body":"blabla",
"title":"one title"
"icon":"notification_icon"
}
是问题所在。
我认为JSON消息分为两部分,&#34;数据&#34;当应用程序打开时,&#34;通知&#34;当应用关闭或在后台时。
我认为,因为应用程序已关闭,android怎么知道他必须显示通知?这就是为什么使用&#34; notification&#34;指定android必须显示通知。
但不,&#34;通知&#34;用于发送简单通知而无需操作。
所以我通过发送此JSON来解决问题:
"data":{
"body":"blabla",
"title":"one title"
},
"registration_ids":["id1", "id2", etc]
