How to uninstall an app completely from android(to solve signature errors)?

I am developing an app from so many days and i use my phone to test the app. So android studio always installs my app in my phone directly through ADB.

Today i made a signed apk from android studio and when i tried to install it. It gave me an error "App not installed - an existing package by the same name with a conflicting signature is already installed"

So i uninstalled the old app and when i tried to install the signed apk it gave me error again"App not installed"

Solution

  • I Think my old app still left some Data in my phone.

    So i used Titanium BackUp Manager and in first removed the app data and then uninstalled the old app.

    This solved the problem and i was able to install my new app now.

    Any,Other suggestions are welcome ??
