Hello could somebody help me with what i'm doing wrong.
I want this application to work in the background, i just want to make in a button where to stop the locationmanager. when i use the removeUpdates, its not working. I cant call that function there.
public class LbsGeocodingActivity extends Activity {
private static final long MINIMUM_DISTANCE_CHANGE_FOR_UPDATES = 1; // in Meters
private static final long MINIMUM_TIME_BETWEEN_UPDATES = 60000; // Minuten(van milliseconden) * aantal
protected LocationManager locationManager;
protected LocationListener locationListener;
protected Button retrieveLocationButton;
protected Button stopLocationButton;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
retrieveLocationButton = (Button) findViewById(R.id.retrieve_location_button);
stopLocationButton = (Button) findViewById(R.id.stop_location_button);
LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
MINIMUM_TIME_BETWEEN_UPDATES,
MINIMUM_DISTANCE_CHANGE_FOR_UPDATES,
new MyLocationListener()
);
retrieveLocationButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
showCurrentLocation();
}
});
retrieveLocationButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
LocationManager.removeUpdates(locationListener) ; }
});
}
protected void showCurrentLocation() {
Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (location != null) {
String message = String.format(
"Current Location \n Longitude: %1$s \n Latitude: %2$s",
location.getLongitude(), location.getLatitude()
);
Toast.makeText(LbsGeocodingActivity.this, message,
Toast.LENGTH_LONG).show();
}
}
public class MyLocationListener implements LocationListener {
public void onLocationChanged(Location location) {
String message = String.format(
"New Location \n Longitude: %1$s \n Latitude: %2$s",
location.getLongitude(), location.getLatitude()
);
Toast.makeText(LbsGeocodingActivity.this, message, Toast.LENGTH_LONG).show();
}
public void onStatusChanged(String s, int i, Bundle b) {
Toast.makeText(LbsGeocodingActivity.this, "Provider status changed",
Toast.LENGTH_LONG).show();
}
public void onProviderDisabled(String s) {
Toast.makeText(LbsGeocodingActivity.this,
"Provider disabled by the user. GPS turned off",
Toast.LENGTH_LONG).show();
}
public void onProviderEnabled(String s) {
Toast.makeText(LbsGeocodingActivity.this,
"Provider enabled by the user. GPS turned on",
Toast.LENGTH_LONG).show();
}
}
I really need this badly
Change the code from this (* indicates whats changed *):
***retrieveLocationButton***.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
locationManager.removeUpdates(locationListener) ;
}
});
To this:
stopLocationButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
locationManager.removeUpdates(locationListener) ;
}
});
EDIT:
use locationManager
"the global variable which starts with small letter" and not LocationManager
"the class which starts with capital letter" for the function removeUpdates()
