I have developed an application and installed the app by running the code on my device. The problem is, only this application cannot be uninstalled. I have tried both the settings>Application Manager>App>Uninstall and Uninstall by dragging from Home.

Every time I try to uninstall by dragging, it shows package installed has stopped. From Settings, when I click on the application, it shows Settings has stopped and throws me out of the Application manager.

Can anyone tell me, what is the possible cause of it and how can I get rid of that specific application? Or at least, what are the ways to do that?

I have tried adb uninstall “package name” which shows failure [Delete_failed_Internal_Error]

N.B: My phone is not rooted.So better if suggested without rooting.
