    copied!<p>In my application, I already have some static overlays on the map, and one dynamic which changes it's place when GPS coords change.</p> <p>My problem is that, when the GPS coords change, I have to clear the dynamic overlay and create a new one, but when I do that, it clears all the overlays, using:</p> <pre><code>mapView.getOverlays().clear(); </code></pre> <p>So, I'm trying to find the better way to do it.</p> <p>Clear all the overlays and then place them again on the map (memory consuming) or can I clear a specific overlay?</p> <p>Thanks</p> <p><strong>Edit:</strong></p> <p><em>This is the dynamic marker:</em></p> <pre><code>@Override public void onLocationChanged(Location location) { Log.d("Location", "onLocationChanged with location " + location.toString()); mLatitude = (int) (location.getLatitude() * 1E6); mLongitude = (int) (location.getLongitude() * 1E6); GeoPoint gpt = new GeoPoint(mLatitude,mLongitude); markerYou.clear(); markerYou.add(new OverlayItem(getString(R.string.markerYou), getString(R.string.markerYouDescription), gpt)); mMyLocationOverlay = new ItemizedIconOverlay&lt;OverlayItem&gt;(markerYou, new ItemizedIconOverlay.OnItemGestureListener&lt;OverlayItem&gt;() { @Override public boolean onItemSingleTapUp(final int index, final OverlayItem item) { Toast.makeText(ShowMap.this, getString(R.string.markerYouDescription), Toast.LENGTH_SHORT).show(); return true; } @Override public boolean onItemLongPress(final int index, final OverlayItem item) { Toast.makeText(ShowMap.this, getString(R.string.markerYouDescription),Toast.LENGTH_SHORT).show(); return true; } }, mResourceProxy); mapView.getOverlays().clear(); mapView.getOverlays().add(mMyLocationOverlay); mapView.invalidate(); mapController.setCenter(gpt); } </code></pre> <p><em>This is the function that places the static markers:</em></p> <pre><code>public void putPlacesOfInterest(){ this.dh = new DataHelper(ShowMap.this); List&lt;Pontos&gt; list = this.dh.selectAll(); for(Pontos p : list){ markerPlaces.add(new OverlayItem(p.getName().toString(), p.getName().toString(), new GeoPoint(p.getLat(), p.getLng()))); } mMyLocationOverlay = new ItemizedIconOverlay&lt;OverlayItem&gt;(markerPlaces, new OnItemGestureListener&lt;OverlayItem&gt;() { @Override public boolean onItemLongPress(int index, OverlayItem item) { Toast.makeText(ShowMap.this, "Item " + item.mTitle, Toast.LENGTH_LONG).show(); return true; } @Override public boolean onItemSingleTapUp(int index, OverlayItem item) { Toast.makeText(ShowMap.this, "Item " + item.mTitle, Toast.LENGTH_LONG).show(); return true; } }, mResourceProxy); mapView.getOverlays().add(mMyLocationOverlay); mapView.invalidate(); } </code></pre>
