Apk exits when i turn on the screen after turn off

i put the next code in my app,i’m using cordova and ionic.

$scope.pos = navigator.geolocation.getCurrentPosition(onSuccess, onError, {
timeout: 8000,
maximumAge: 9000,
enableHighAccuracy: true

});
the problem is: when i use “ionic run” and install de debug.apk the device is working fine, but when:

-i signin the apk

-the apk is inactive, and i put the apk active again. the apk exits.

in the console, it does not throw me any error
