how to run application in background in android?Come eseguire applicazioni Android in background
sto facendo progetto utilizzando location manager se la mia posizione di latitudine e longitudine pari alla stessa che è in mobili di database il profilo dovrebbe andare in modalità silenziosa. Quindi devo continuare ad aggiornare la mia posizione utilizzando il local manager. L'ho fatto. ma se chiudo la mia app non funziona. ma la mia app dovrebbe funzionare anche se chiudo la mia app.io ho provato con il task async quando ho chiuso l'app, ma dopo aver passato alla modalità loudly non cambia in silent.i devo anche ricevere una notifica quando la mia app viene eseguita n help.tks background..please di anticipo
ecco il mio codice
