问题
I am uploading android application on google play but It is showing error as : You need to use a different package name because "com.Mobile.mytestbuddy" is already used by one of your other applications There is already one app of version 1.2 in google play and this new app's version is 1.29
- What is the wrong with this ?
- Do I need to change anything or
- Do I need to unpublish old app before uploading this new version app ?

I have solved this problem.
I was adding new Application that's why I was getting error. I click on the application which I wanted to update and there I found option to upload New APK file, I did it and It has been updated.

This problem is arise because you did sign this apk with different debug-keystore. Check it and then reply i will give some more alternatives.
