如果我的问题太简单,请道歉。
目前我正在开发一个 android 应用程序,其中我将收到多个警报(来自服务器),并且我必须一个接一个地查看所有推送警报(在移动通知列表中)。
我在下面给出了我的代码。我的服务器正在成功地将所有 GCM 推送警报通知发送到我的 android 手机。
但是,我只能查看最后发送的推送警报(在通知列表中)。也就是说,考虑我的服务器正在发送 2 个推送警报:PUSH_A 和 PUSH_B。在我的安卓手机中,我只能查看第二个警报:PUSH_B。
请你说,我做错了什么。我必须一个接一个地查看移动设备中的所有推送警报(通知列表中的 PUSH_A 和 PUSH_B)。
我的服务器代码如下:
Sender aGcmSender = new Sender(API_KEY);
//Constructing message which need to be transmitted to android device.
Message aMessage = new Message.Builder().addData("message", thePushMsg).build();
Result aResult = aGcmSender.send(aMessage, theRegId, 1); //Transmitting message to android device
if(aResult != null)
{
if(aResult.getMessageId() != null)
{
String aCanonicalRegistrationId = aResult.getCanonicalRegistrationId();
if(aCanonicalRegistrationId != null)
{
//updating aCanonicalRegistrationId to my database
}
itsLogger.info("Push notification successfully sent to cub of phone: "+theCubsPhone);
itsLogger.info("Message Id:"+aResult.toString());
}
else
{
String error = aResult.getErrorCodeName();
itsLogger.info("Android Push Notification: Failed to send push notification to phone" + thePushMsg);
if (error.equals(Constants.ERROR_NOT_REGISTERED)) {
// application has been removed from device - unregister database
}
}
}
手机中的 GCM 代码: * AndroidManifest.xml: *
<permission android:name="MyProjectPackage.permission.C2D_MESSAGE" android:protectionLevel="signature" />
<uses-permission android:name="MyProjectPackage.permission.C2D_MESSAGE" />
<!-- App receives GCM messages. -->

<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="MyProjectPackage" />
</intent-filter>
</receiver>
<service android:name=".GCMIntentService" />
GCMIntentService:
private void sendGCMIntent(final Context theContext, String theMessage)
{
int icon = R.drawable.icon;
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager)
theContext.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, theMessage, when);
String title = theContext.getString(R.string.app_name);
Intent notificationIntent = new Intent();
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent =
PendingIntent.getActivity(theContext, 0, notificationIntent, 0);
notification.setLatestEventInfo(theContext, title, theMessage, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
// Play default notification sound
notification.defaults |= Notification.DEFAULT_SOUND;
// Vibrate if vibrate is enabled
notification.defaults |= Notification.DEFAULT_VIBRATE;
notificationManager.notify(0, notification);
}
请提供任何帮助。
谢谢你。
