Android Question [B4XPages] Errors when trying to run GoogleMaps Example

[vfafou]

Hello!

I'm starting to use B4XPages and I'm studying several useful for my needs examples.
Trying to run the GoogleMaps example, the first error I was having without try to debug, was at compiling process and it is the following:

Generating R file.    Error
AndroidManifest.xml:29: error: Error: No resource found that matches the given name (at 'value' with value '@integer/google_play_services_version').

Then I added to the manifest the lines of the GoogleMaps2 library example and added the 2 additional jars (maps and location).
The compilation was successful but at runtime I have the following:

java.lang.RuntimeException: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.Boolean.booleanValue()' on a null object reference

What is going wrong?

Thank you in advance!

review SDK Manager and Manifest.

Note: the api key that the demo brings does not show the map.

Thank you very much @oparra!
My only problem was that I hadn't seen the library update! My version was 2.02.
