MapActivity - How to restrict zoom levels?

Issue

I implemented a MapActivity with Pins on it, following HelloMapView Tutorial and many StackOverflow resources.

For the purpose of my app, I would like to limit the zoom levels with a minimum and a maximum. In fact I would like to avoid using android:clickable="true" on my MapView.

I could not find how do achieve that.

• Is it possible?
• Does someone knows how to do that?
• Is there a built-in function to override like onZoomChanged() that I did not see?

AndroidManifest.xml

<uses-sdk
    android:maxSdkVersion="16"
    android:minSdkVersion="7"
    android:targetSdkVersion="15" />

MyMapActivity.java

// Here is my MapView
mMapView = (MapView) findViewById(R.id.game_map);
mMapView.setBuiltInZoomControls(false);
mMapView.setSatellite(true);
mMapController = mMapView.getController();
mMapController.setZoom(CONST_MAP_ZOOM);
mMapController.setCenter(new GeoPoint(48856700, 2351000));
mMapController.animateTo(new GeoPoint(48856700, 2351000));

But when I use fingers, I can zoom out until I see the whole planet.

What I would like would be to limit the zoom levels.

Solution

I found a way out.

I disable multi-touche on the MapView:

<com.google.android.maps.MapView
    android:id="@+id/game_map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:apiKey="@string/google_maps_api_key"
    android:clickable="true" />

Then I hide zoom controls:

mMapView = (MapView) findViewById(R.id.game_map);
mMapView.setBuiltInZoomControls(false);

Then I implement my own zoom controls.
