Device and Android version:

What make and model device = Samsung Galaxy S5
Android version Ice Cream Sandwich

I am confused on how to add this into a project:

com.google.maps.android
android-maps-utils-apklib
0.4+
apklib

any help would be appreciated: kenneth.lee.[email protected]

I had this problem, and after many days I found a solution by adding android:hardwareAccelerated="true" to my MapsActivity on AndroidManifest.xml

Example:

<activity
            android:name=".MapsActivity"
            android:configChanges="orientation"
            android:hardwareAccelerated="true"
            android:screenOrientation="portrait" />
