Android : APK's package name must be in the following format "com.example.myapp". It may contain letters (a-z), numbers, and underscores (_)

I got this error while uploading apk to playstore.

Your APK's package name must be in the following format "com.example.myapp". It may contain letters (a-z), numbers, and underscores (_). It must start with a lowercase character.

I created apk in eclipse ( file -> export -> export android application )

I have attached package structures of the application and the manifest file. please help me out .

Thanks
