Add bounds to map to avoid swiping outside a certain region

Question

My app shows a map and i want that users can\'t swipe over a certain region. So i\'m trying to add bounds but it makes the app to crash. Here is the working code:

Answer 1

Caused by: java.lang.IllegalStateException: Error using newLatLngBounds(LatLngBounds, int): Map size can't be 0. Most likely, layout has not yet occured for the map view. Either wait until layout has occurred or use newLatLngBounds(LatLngBounds, int, int, int) which allows you to specify the map's dimensions.

From the docs https://developer.android.com/reference/com/google/android/gms/maps/CameraUpdateFactory.html#newLatLngBounds(com.google.android.gms.maps.model.LatLngBounds, int)

Do not change the camera with this camera update until the map has undergone layout (in order for this method to correctly determine the appropriate bounding box and zoom level, the map must have a size). Otherwise an IllegalStateException will be thrown. It is NOT sufficient for the map to be available (i.e. getMap() returns a non-null object); the view containing the map must have also undergone layout such that its dimensions have been determined. If you cannot be sure that this has occured, use newLatLngBounds(LatLngBounds, int, int, int) instead and provide the dimensions of the map manually.

Note: getMap() could return null. It is better to check for Availability of Google play services before initialize GoogleMap object.
