To fix this, right-click your project, properties, build path and go to export tab. There make sure “Android private libraries” are checked. A clean and rebuild should put you on track …
Right-click the project in Eclipse’s Package Explorer and choose Properties.
Choose Java Build Path
Choose Order and Export
Check the boxes next to Android Private Libraries and Android Dependencies
After making these changes, do a clean and then rebuild.
With this change, I was able to build an APK that installed and ran on an Android device.
