Accepted Answer

If you install the application on your device via adb install you should look for the reinstall option which should be -r. So if you do adb install -r you should be able to install without uninstalling before.

You are getting that error because an application with a package name same as your application already exists. If you are sure that you have not installed the same application before, change the package name and try.

Else wise, here is what you can do:

  1. Uninstall the application from the device: Go to Settings -> Manage Applications and choose Uninstall OR
  2. Uninstall the app using adb command line interface: type adb uninstall After you are done with this step, try installing the application again.
