Issue
I just try to create a Android project from the existing code in Eclipse. Everything seems fine without error prompt. Also I can test it in virtual device. So I tried to create a apk by exported unsigned application package. Finally the app cannot be installed to my android and it just prompt the "App not installed" message! How can I fix it? Thanks.
Solution
take apk from bin folder and try to install it on device...not from create apk by exported unsigned package.make sure you have sufficient internal memory (that should be more than just the app size, because app needs to store data too).
