小编Jit*_*P.S的帖子

我正在我的Android应用程序中执行由GCM触发的推送通知.我想显示通知,如果应用程序在警告框中运行,如果应用程序未运行意味着不在前台只显示状态栏通知,您如何确定应用程序是否正在运行并且在前台？是这可以显示这样的通知.现在使用此代码显示状态栏推送通知

  NotificationManager notificationManager = (NotificationManager)
                context.getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notification = new Notification(icon, message, when);

        String title = context.getString(R.string.app_name);

         Intent notificationIntent = new Intent(context, BottomActivity.class);
        // 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(context, 0, notificationIntent, 0);
        notification.setLatestEventInfo(context, title, message, intent);
        notification.flags |= Notification.FLAG_AUTO_CANCEL;

        // Play default notification sound
        notification.defaults |= Notification.DEFAULT_SOUND;

        //notification.sound = Uri.parse("android.resource://" + context.getPackageName() + "your_sound_file_name.mp3");

        // Vibrate if vibrate is enabled
        notification.defaults |= Notification.DEFAULT_VIBRATE;
        notificationManager.notify(0, notification); 

目前我正在使用xmpp/jabber聊天for android.i刚尝试使用Openfire并尝试连接我的jabber account.connection成功.但我无法发送任何message.it显示一些冲突错误.请检查错误日志给我一个解决方案.

在运行应用程序时,Android Studio中出现意外错误,以下是错误消息

我也粘贴了我的build.gradle文件
