我正在尝试实现 GCM 客户端和服务器架构。到目前为止一切正常。
例外:当我的活动关闭并且我收到 GCM 的新通知时,通知会显示在通知栏中。到目前为止,一切都很好。但是当我点击通知时,我的活动被打开但onReceive
我的事件BroadcastReceiver
没有被触发。:( 如果 Activity 已打开,onReceive
则完美触发。
你知道,这里有什么问题吗?
干杯
克里斯
所以这是我的服务:
package xy;
import ...;
public class GcmIntentService extends IntentService
{
private NotificationManager mNotificationManager;
NotificationCompat.Builder builder;
public GcmIntentService()
{
super("GcmIntentService");
}
@Override
protected void onHandleIntent(Intent intent)
{
Bundle extras = intent.getExtras();
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
String messageType = gcm.getMessageType(intent);
if (!extras.isEmpty()) { // has effect of unparcelling Bundle
final int notificationID = (int) (Math.random() * 100000000);
if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
sendNotification("GCM notification: Send error", extras.toString(), notificationID);
} else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType)) {
sendNotification("Deleted messages on server", extras.toString(), notificationID);
// If it's a regular GCM message, do some work.
} else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType)) {
sendNotification(extras.getString(Utils.TICKER_TITLE_MESSAGE_KEY), extras
.getString(Utils.TICKER_TEXT_MESSAGE_KEY), notificationID);
Intent intentToBroadCast = new Intent(Utils.DISPLAY_MESSAGE_ACTION);
intentToBroadCast.putExtra(Utils.MESSAGE_EXTRA_BUNDLE_KEY, extras);
intentToBroadCast.putExtra(Utils.NOTIFICATION_ID_KEY, notificationID);
sendBroadcast(intentToBroadCast);
}
}
// Release the wake lock provided by the WakefulBroadcastReceiver.
GcmBroadcastReceiver.completeWakefulIntent(intent);
}
private void sendNotification(final String aTitle, final String aText, final int aNotificationID)
{
mNotificationManager = (NotificationManager) this
.getSystemService(Context.NOTIFICATION_SERVICE);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this,
DemoActivity.class), 0);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this).setSmallIcon(
R.drawable.ic_stat_gcm).setContentTitle(aTitle).setStyle(
new NotificationCompat.BigTextStyle().bigText(aText)).setContentText(aText);
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(aNotificationID, mBuilder.build());
}
}
这是我活动中的接收器,用于显示传入消息:
public class GcmResultReceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
Bundle extras = intent.getBundleExtra(Utils.MESSAGE_EXTRA_BUNDLE_KEY);
String s = extras.getString(Utils.CONTENT_TITLE_MESSAGE_KEY) + "\n"
+ extras.getString(Utils.CONTENT_TEXT_MESSAGE_KEY);
mDisplay.setText(s);
int notificationID = intent.getIntExtra(Utils.NOTIFICATION_ID_KEY, -1);
if (-1 != notificationID) m_SentNotificationIDs.add(notificationID);
if (m_IsVisible) {
clearNotifications();
}
}
};
一切都是从 Google Android 教程中的 GCM 示例复制和改编的。
