I have created a project as per instructions at http://blog-emildesign.rhcloud.com/?p=435 which was instructed at some other query.
It was not working in Android Virtual Device which came with the eclipse I downloaded. I was getting some error regarding GPU V2 was required. So I configured Genymotion virtual device with Eclipse and its working very smoothly.
After that I exported the project and created .apk file. Then I unistalled the app from the virtual device and re-installed the .apk file which was extracted. On doing that the map is not getting displayed. The same thing is occuring when the file is installed in a real device (Samsung Note II).
Please help!!
