android - background services for getting activity recognition -

i read lot services tried lot of examples unfortunately couldn't understand how keep services running activity recognition api , running.

in cases android os killing somehow running service.

what tried:

i put start_sticky when killed never runs again

@override public int onstartcommand(intent intent, final int flags, int startid) {      // code here     return start_sticky; }

started service again when detected service killed. not worked expected. sending broadcast , starting service again.

@override public void ondestroy() {     sendbroadcast(new intent("youwillneverkillme"));     super.ondestroy(); }

know foreground services in case there no way can use foreground services. have forget solution.

is there other way can suggest me solution? doing there facebook or viber getting messages?
