显示推送通知，只有当应用程序无法运行Android [英] Show push notification only when app is not running android

问题描述

在我的应用我有集成推送通知GCM 。它的做工精细，每当谈到通知其出现。但是，当用户在应用内推送通知来连。我想通知显示，只有当用户的应用程序之外。

下面是我的code的推送通知：

  

GcmBroadcastReceiver

 公共类GcmBroadcastReceiver扩展WakefulBroadcastReceiver {@覆盖
公共无效的onReceive（上下文的背景下，意图意图）{
    组件名补偿=新的组件名（GCMNotificationIntentService.class.getPackage（）的getName（）
            GCMNotificationIntentService.class.getName（））;
    startWakefulService（上下文，（intent.setComponent（化合物）））;
    的setResult code（Activity.RESULT_OK）;
}
}

        如果（GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals（为messageType））{
            sendNotification的（发送错误：+ extras.toString（））;
        }否则如果（GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals（为messageType））{
            sendNotification的（在服务器上删除的邮件：+ extras.toString（））;
            //如果是一个普通GCM消息，做了一些工作。
        }否则如果（GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals（为messageType））{
            sendNotification时（extras.getString（信息））;
            Log.i（TAG，收到：+ extras.toString（））;

    }
    //释放该WakefulBroadcastReceiver提供的唤醒锁。
    GcmBroadcastReceiver.completeWakefulIntent（意向）;

    URI URI = RingtoneManager.getDefaultUri（RingtoneManager.TYPE_NOTIFICATION）;
    mBuilder.setSound（URI）;
    mBuilder.setContentIntent（co​​ntentIntent）;
    mBuilder.setAutoCancel（真）;
    mNotificationManager.notify（notificationId ++ mBuilder.build（））;
}
}
 

  

在ManifestFile

 ＆lt;接收

    ＆LT; /接收器＆GT;
  ＆LT;服务机器人。GCMNotificationIntentServiceNAME = /＆GT;
 

任何建议将是非常美联社preciated！

解决方案

做这样的事情，检查是否应用程序是在前台还是不通过调用下面的方法，并根据返回值true或false做你的工作，休息

 公共布尔checkApp（）{
       ActivityManager AM =（ActivityManager）本
                .getSystemService（ACTIVITY_SERVICE）;        //从当前运行的任务的信息
        清单＆LT; ActivityManager.RunningTaskInfo＆GT; taskInfo = am.getRunningTasks（1）;        组件名componentInfo = taskInfo.get（0）.topActivity;
        如果（componentInfo.getPackageName（）。equalsIgnoreCase（YourPackage））{
            返回true;
        }其他{
           返回false;
        }
  }
 

In my application I have push notification integrated with GCM. Its working fine whenever notification comes its appearing. But push notification come even when user is inside the app. I want notifications to appear only when user is outside the app.

Here is my code for push notification:

GcmBroadcastReceiver

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    ComponentName comp = new ComponentName(GCMNotificationIntentService.class.getPackage().getName(), 
            GCMNotificationIntentService.class.getName());
    startWakefulService(context, (intent.setComponent(comp)));
    setResultCode(Activity.RESULT_OK);
}
}

GCMnotificationIntentService.Class

public class GCMNotificationIntentService extends IntentService {

public static int notificationId = 10;
private NotificationManager mNotificationManager;
NotificationCompat.Builder builder;
private boolean login_status = false;


public GCMNotificationIntentService() {
    super("GcmIntentService");
}

public static final String TAG = GCMNotificationIntentService.class.getSimpleName();

@Override
protected void onHandleIntent(Intent intent) {
    Bundle extras = intent.getExtras();
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
    // The getMessageType() intent parameter must be the intent you received
    // in your BroadcastReceiver.
    String messageType = gcm.getMessageType(intent);

    if ( !extras.isEmpty() ) { // has effect of unparcelling Bundle
        /*
         * Filter messages based on message type. Since it is likely that
         * GCM will be extended in the future with new message types, just
         * ignore any message types you're not interested in, or that you
         * don't recognize.
         */
        if ( GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType) ) {
            sendNotification("Send error: " + extras.toString());
        } else if ( GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType) ) {
            sendNotification("Deleted messages on server: " + extras.toString());
            // If it's a regular GCM message, do some work.
        } else if ( GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType) ) {
            sendNotification(extras.getString("message"));
            Log.i(TAG, "Received: " + extras.toString());
        }
    }
    // Release the wake lock provided by the WakefulBroadcastReceiver.
    GcmBroadcastReceiver.completeWakefulIntent(intent);
}

private void sendNotification(String msg) {

    mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);

    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this).setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle(getString(R.string.notification_title))
            .setStyle(new NotificationCompat.BigTextStyle().bigText(msg)).setContentText(msg);
    Uri uri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    mBuilder.setSound(uri);
    mBuilder.setContentIntent(contentIntent);
    mBuilder.setAutoCancel(true);
    mNotificationManager.notify(notificationId++, mBuilder.build());
}
}

In ManifestFile

 <receiver
        android:name=".GcmBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

            <category android:name="com.medlife.deliveryagent" />
        </intent-filter>
    </receiver>
  <service android:name=".GCMNotificationIntentService" />

Any suggestions would be highly appreciated!!!

解决方案

Do something like this to check whether you app is in foreground or not by calling below method and depending on returning value true or false do your rest of work

public boolean checkApp(){
       ActivityManager am = (ActivityManager) this
                .getSystemService(ACTIVITY_SERVICE);

        // get the info from the currently running task
        List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(1);

        ComponentName componentInfo = taskInfo.get(0).topActivity;
        if (componentInfo.getPackageName().equalsIgnoreCase("YourPackage")) {
            return true;
        } else {
           return false;
        }
  }
