copied!<p>I got the same problem and I tried to solve it with the good answer of Devunwired, but I had some troubles. I couldn't find a way to stop the service and when I finished my app the GPS-module was still running. So i found another way:</p> <p>I wrote a GPS.java class:</p> <pre><code>public class GPS { private IGPSActivity main; // Helper for GPS-Position private LocationListener mlocListener; private LocationManager mlocManager; private boolean isRunning; public GPS(IGPSActivity main) { this.main = main; // GPS Position mlocManager = (LocationManager) ((Activity) this.main).getSystemService(Context.LOCATION_SERVICE); mlocListener = new MyLocationListener(); mlocManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, mlocListener); // GPS Position END this.isRunning = true; } public void stopGPS() { if(isRunning) { mlocManager.removeUpdates(mlocListener); this.isRunning = false; } } public void resumeGPS() { mlocManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, mlocListener); this.isRunning = true; } public boolean isRunning() { return this.isRunning; } public class MyLocationListener implements LocationListener { private final String TAG = MyLocationListener.class.getSimpleName(); @Override public void onLocationChanged(Location loc) { GPS.this.main.locationChanged(loc.getLongitude(), loc.getLatitude()); } @Override public void onProviderDisabled(String provider) { GPS.this.main.displayGPSSettingsDialog(); } @Override public void onProviderEnabled(String provider) { } @Override public void onStatusChanged(String provider, int status, Bundle extras) { } } } </code></pre> <p>This class is used in every Activity which needs the GPS coordinates. Every Activity has to implement the following Interface (needed for the communication): </p> <pre><code>public interface IGPSActivity { public void locationChanged(double longitude, double latitude); public void displayGPSSettingsDialog(); } </code></pre> <p>Now my main Activity looks like that:</p> <pre><code>public class MainActivity extends Activity implements IGPSActivity { private GPS gps; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); gps = new GPS(this); } @Override protected void onResume() { if(!gps.isRunning()) gps.resumeGPS(); super.onResume(); } @Override protected void onStop() { gps.stopGPS(); super.onStop(); } public void locationChanged(double longitude, double latitude) { Log.d(TAG, "Main-Longitude: " + longitude); Log.d(TAG, "Main-Latitude: " + latitude); } @Override public void displayGPSSettingsDialog() { Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS); startActivity(intent); } } </code></pre> <p>and a second one like that:</p> <pre><code>public class TEST4GPS extends Activity implements IGPSActivity{ private GPS gps; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.gps = new GPS(this); } @Override public void locationChanged(double longitude, double latitude) { Log.d("TEST", "Test-Longitude: " + longitude); Log.d("TEST", "Test-Latitude: " + latitude); } @Override protected void onResume() { if(!gps.isRunning()) gps.resumeGPS(); super. onResume(); } @Override protected void onStop() { gps.stopGPS(); super.onStop(); } @Override public void displayGPSSettingsDialog() { Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS); startActivity(intent); } } </code></pre> <p>It's not as beautiful as the solution of Devunwired, but it works for me. cya</p>
