Re-installation failed due to different application signatures

Question

I moved my Android project to a laptop and now I get this when I hit Debug. Sounds like this is a bug? This shouldn\'t happen via Eclipse as far as I know.

Answer 1

For me after I copied all of my keystore files from my machine at home, I had to do a Project->clean. After that it worked perfectly.

Answer 2

I had the same issue using the Droid emulator. I solved it by uninstalling the package from the application settings in the emulator as you would a normal device. On the next run, it reinstalled and the error went away.

Answer 3

I also had the same problem and fixed it by uninstalling the app and reinstall it again.

Answer 4

I got the same problem and fixed it by just wiping the user data on the emulator. My guess is that the emulator keeps the project installed unless you wipe the data, so if your new project doesn't match some internal parameters it doesn't like it and won't reinstall it.

Answer 5

I also got the same problem and fixed it. you should do the following to fix it,

1. Uninstall the application from your mobile if you load it already.

2. To uninstall goto settings->application->manage application.

3. Run the application again and choose the mobile

Hope this will help you

Answer 6

When i tried to uninstall the application from my device after this issue occurs, i cannot able to find the app in my device. I don know where it gone. Then i uninstalled using adb,

adb -d uninstall <app package name>

This is the answer who are facing the issue similar to my problem.
