java - LibGDX Timer doesn't start after game resumed on android -

i'm creating 2 timers in code. 1 logic timer updates logic every 0.017 seconds:

logictimer = new timer();     logictimer.scheduletask(new timer.task() {         @override         public void run() {             updatelogic();         }     }, 0f, timeperprocessing); 

and other 1 generating obstacles every 3 seconds:

meteoroidtimer = new timer();     meteoroidtimer.scheduletask(new timer.task() {         @override         public void run() {             generatemeteoroids();         }     },1f,3f); 

when pause game , resume afterwards, logic timer still works obstacle timer doesn't. thought because use random object in method call in timer, tried simple:

system.out.println("it showing"); 

and still doesn't resume.

my code pause , resume:

@override public void pause(){     meteoroidtimer.stop();     logictimer.stop(); }  @override public void resume(){     meteoroidtimer.start();     logictimer.start(); } 

you dont need use timer.stop , star on resume because when leave app libgdx stops rendering/updating anyway timers wont updated anyway.
