根据this,我正在实施Google Developers Guide个代码。
一切正常,我可以成功接收通知数据。
如果你检查GCMIntentService.java文件的第70行,它会回显这行到LogCat:
I/GCM Demo(6653): Working... 1/5 @ 8656981
I/GCM Demo(6653): Working... 2/5 @ 8657982
I/GCM Demo(6653): Working... 3/5 @ 8658983
I/GCM Demo(6653): Working... 4/5 @ 8659983
I/GCM Demo(6653): Working... 5/5 @ 8660984
I/GCM Demo(6653): Completed work @ 8661985
I/GCM Demo(6653): Received: Bundle[{msg=messagehere, from=SENDERIDHERE, android.support.content.wakelockid=3, collapse_key=do_not_collapse}]
所以我的设备正在接收通知数据,但设备的状态栏中没有可见的通知。什么都没发生。
你能告诉我为什么这些推送通知不会显示在我的设备上,只能在LogCat中显示吗?
更新
这是我的sendNotification()方法:
private void sendNotification(String msg) {
mNotificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
new Intent(this, MainActivity.class), 0);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setContentTitle("GCM Notification")
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(msg))
.setContentText(msg);
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}

你能试试这种方法......这个对我有用。虽然和你的差不多......
private void sendNotification(String msg)
{
int uniqueId = (int) (System.currentTimeMillis() & 0xfffffff);
mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP
| Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent contentIntent = PendingIntent.getActivity(this, uniqueId,
intent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Hello")
.setStyle(new NotificationCompat.BigTextStyle().bigText("Hello"))
.setContentText("This is your notification content")
.setAutoCancel(true)
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(uniqueId, mBuilder.build());
}
唤醒手机是完全不同的事情。您可以通过这种方式使用WakeLock来实现:
设置通知时:
WakeLock screenOn = ((PowerManager)getSystemService(POWER_SERVICE)).newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "test");
screenOn.acquire();
是的,当你不再需要它时,不要忘记释放唤醒锁(可能是在5秒之后或点击通知;根据你的需要,根据需要):
screenOn.release();

看起来(在您的Android清单文件中)该服务可能尚未启用
请尝试将<service android:name=".GcmIntentService" />
替换为:
<service android:enabled="true" android:name=".GcmIntentService" />
