I need to be able to start chronometer, then close activity, after that through notifications, back to that activity, and see the right time in chronometer.
A part of my Activity:
public void doClick(View target)
{
switch(target.getId())
{
case R.id.buttonStart:
{
Mchronometer.setBase(SystemClock.elapsedRealtime());
Mchronometer.start();
Intent intent = new Intent(RecentActivity.this, ChronometerService.class);
intent.putExtra("task_name",task_name);
intent.putExtra("task_id",task_id);
intent.putExtra("ellapsedTime",Mchronometer.getBase());
Log.d("base",""+Mchronometer.getBase());
startService(intent);
break;
}
case R.id.buttonStop:
{
stopService(new Intent(RecentActivity.this, ChronometerService.class));
Mchronometer.stop();
Mchronometer.setBase(SystemClock.elapsedRealtime());
break;
}
case R.id.button3:
{
break;
}
}
}
A part of my Service:
public class ChronometerService extends Service {
private ThreadGroup myThreads = new ThreadGroup("ServiceWorker");
private NotificationManager notificationMgr;
private int task_id;
private long ellapsedTime;
@Override
public void onCreate() {
super.onCreate();
notificationMgr = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
super.onStartCommand(intent, flags, startId);
String task_name =intent.getExtras().getString("task_name");
task_id =intent.getExtras().getInt("task_id");
ellapsedTime = intent.getExtras().getLong("ellapsedTime");
Log.d("servicebase",""+ellapsedTime);
displayNotificationMessage(task_name);
new Thread(myThreads, new ServiceWorker(),"ChronometerService").start();
return START_STICKY;
}
private class ServiceWorker implements Runnable {
public void run() {
}
}
@Override
public void onDestroy()
{
myThreads.interrupt();
notificationMgr.cancelAll();
super.onDestroy();
}
public IBinder onBind(Intent intent) {
return null;
}
public void displayNotificationMessage(String message){
Notification notification = new Notification(R.drawable.emo_im_winking,message,System.currentTimeMillis());
notification.flags = Notification.FLAG_NO_CLEAR;
Intent intent = new Intent(this, RecentActivity.class);
intent.putExtra("task_id", task_id);
intent.putExtra("ellapsedTime",ellapsedTime);
Log.d("servicebase1",""+Long.toString(ellapsedTime));
PendingIntent contentintent = PendingIntent.getActivity(this,0,intent,0);
notification.setLatestEventInfo(this,"ChronometerService",message,contentintent);
notificationMgr.notify(0, notification);
}
}
I tried to send a message from activity to a service, which contains elapsed information. If I started it first on my device (after system load) it's works right, but when I launch it again. The activity receives wrong message. It receives the time of the first service launched on the device.
As you can see I also send one more variable, and activity reads it correctly.
I've found a solution to my question. It's simple. It's needed to use flag(PendingIntent.FLAG_UPDATE_CURRENT)
PendingIntent contentintent = PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_UPDATE_CURRENT);
And it's work fine.
