Performance issue on Android's MapView Navigation-App -

I have a question about making a navigation app faster and more stable.

The original my app's layer is a simple map view, which is covered with multiple overlays (2 markers for start and destination and one for route).

My idea is to apply a thread to display the path, so that the app will not be hanging during a more complicated route calculation (as it is now).

After updating the thread, no update is shown, you may be able to help me with a little bit of my code below:

  The Private Class Uses MyLocationListener LocationListener {@Override changed the location to Public Zero (location location) {posUser = new GeoPoint (int) (loc.getLatitude () * 1E6), (int) (Public Legacy (*) * 1 A6)); New thread () {public zero run () {mapView.invalidate (); // Delete old overlay mapView.getOverlays (). clear (); // Update overlay elements and update basic map settingsText (); If (first refresh) {adjustMap (); First Replenish = false; } GetAndPaintRoute (); DrawMarkers (); }}; }  

Some attributes are summarized by some method like "Dramacers ()" or "Update Text ()" ... (They do not need to pay more attention - ))

When you are actually asking for the form run ? I only see the code for create . If you did, you will see that only the main (UI) thread is allowed to update, as the RPond notes

Instead, divide your work and
