Solution
Try this one:
link
it's a blog post i wrote on creating a Google Map API V2.
UPDATE:
I took a picture from my working map project. ignore the crash reporting services libs like acra, flurry, bugsense and crittercism. other then those you project looks the same?
do you have `google-play-services_lib.jar` in your Android Dependencies folder?
Problem
New to Android etc. So I was recommended this demo: http://dj-android.blogspot.in/2013/02/android-google-map-v2-part-1.html I followed it, but something must have gone wrong. ... - In workspace I have my own project: - Inside this project: In "Libs" I have added "android-support-v4.jar" - Inside this project: In Android Depencides I have "android-support-v4.jar" - Inside this project: In References Libraries I have "google-play-services.jar" - Inside this project: In References Libraries I have "android-support-v4.jar" ... - In workspace I have google-play-services_lib as a project: - Inside this project: In "Libs" I have "google-play-services.jar" - Inside this project: In "Libs" I have "google-play-services.jar.properties" - Inside this project: In "Android Dependencies" I have "google-play-services.jar" ... When I run above project on SGII v4.1.2 I get black screen followed by crasj followed by error: ``` 03-09 00:28:49.957: E/AndroidRuntime(20309): FATAL EXCEPTION: main 03-09 00:28:49.957:

to the API key somehow? I use this as API key: ``` HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH;com.exampledomain.exampleproject ``` - Notice the ending. Is that correct? - I had to edit the output from keytool, so not 100% sure the API key is good. See: Maps v2 API Key on Android NOTE 2: Some screenshots of my current configuration: If you believe the cause of my problems is that Google Play Services is not installed correctly, I have created a separate SO for that at: Can not install google-play-services into Eclipse correctly (trying to get maps working)
