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

I was facing this problem time and again.Got around a lot of forums, but couldn't find a logical solution for the issue.

I used to get this error message, . . . Uploading test.apk onto device 'emulator-5554' Failed to install test.apk on device 'emulator-5554': timeout Launch canceled!

this error is thrown as the start of emulator and deployment of application takes some significant time and before that the emulator times out.

A simple fix for this problem is keeping the emulator open when this problem occurs, *just run the application again. This only deploys the application on to the already started emulator *. There is not much time consumed during this run as the major part of the time during app deployment is because of slow start up of emulator.

Hope this helps!
