Now use that ServiceConnection to bind and unbind GeolocationService at the appropriate points in the Activity lifecycle. Also, add a new boolean field named 'isBound', and use it to make sure that we only call 'unbindService' if we're actually bound to the Service.
I am getting a error message saying make sure you are binding and unbinding in the related lifecycle calls bind in onStart() and unbind on onStop().
where am I getting it wrong?
public class MainActivity extends Activity {
private boolean isBound = true;
private ServiceConnection serviceConnection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
isBound = true;
}
@Override
public void onServiceDisconnected(ComponentName name) {
isBound = false;
}
};
int latitude;
int longitude;
@Override
public void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.activity_main);
Button updateLocationButton = (Button) findViewById(R.id.update_button);
updateLocationButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v){
}
});
onStart(); {
Intent intent = new Intent(this, GeolocationService.class );
bindService(intent, serviceConnection, Context.BIND_AUTO_CREATE);
isBound = true;
}
onStop(); {
if(isBound){
unbindService(serviceConnection);
isBound = false;
}
}
}
}
public class GeolocationService extends Service {
@Override
public IBinder onBind(Intent intent) {
return null;
}
//Client methods
public int getLatitude() { return getLat(); }
public int getLongitude() { return getLng(); }
}
