Android Question I am trying to run simple map zip.

Larry,
download the lib from here https://www.b4x.com/android/forum/threads/osmdroid-mapview-for-b4a.16309/ and put both files (OSMDroid_3_0_8.jar and OSMDroid_3_0_8.xml) in the b4a Library folder or in the additional library folder. Then run one of the examples provided from Martin, which you can find here: https://www.b4x.com/android/forum/threads/osmdroid-mapview-for-b4a-tutorial.16310/

best regards
stefan

OK that worked but in 03mapsample map I get
Convert byte code - optimized dex. Error
UNEXPECTED TOP-LEVEL EXCEPTION:
java.lang.IllegalArgumentException: already added: Lmicrosoft/mappoint/

This error means that two referenced jars include the same class file. You can open one of the jars with 7zip and delete all the duplicate classes.
