Android Failed to install HelloWorld.apk on device (null) Error

Question

I am new to Android. When I am running my android application in eclipse I am getting these messages in the console:

[2011-03-08 12:57:35 - HelloWorld] ----         


        

Answer 1

Something else you might want to consider is a hard reset of your emulator by wiping your user data.

In order to do this you: - right click your project name in package explorer - go to 'run as' then 'run configuration' - in the 'run configuration' window click the 'target' tab - then tick the name of your chosen emulator - tick 'wipe user data', click apply

And the next time you start up your emulator it should prompt you asking whether you really want to wipe your data. Click yes, and hopefully it helps you to install the app.
