Problema con Google Direction API for Android.
Publicado por Luis Enrique (1 intervención) el 06/05/2017 23:25:36
[b]Buenos dias, tengo el siguiente problema:
Esta linea locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,15000,0, (android.location.LocationListener) locListener); me esta generando que se salga del app y bote error cada vez que entro a ella. segun tutoriales me dice que solo deberia poner locListener sin el parentisis detrás, pero al hacer esto el locListener me aparece subrayado como error. Alguna idea?
