Question by Scrap_Computer · May 19, 2013 at 03:35 AM · android

Unity Android installion error - Help me please!

When i source my sdk folder and attempt to run the program i get the following error:

Error building Player: Exception: android (invokation failed) ERROR: unknown error cmd:android list target -c stdout; stderr: Exception in thread "main" java.lang.NullPointerException at SDKMain.main(SDKMain.java:62)

I honestly can't get it working i have done the following: Re-installed java/sourced the javac correctly Re-installed sdk 4 times with separate versions

I have installed it correctly on another computer without a hitch, so i don't believe i'm doing something seriously wrong, but i could be wrong.

Additional information: Running windows 8 Already contacted support who give me the simple steps on how to install the programs again, which i have already done :)

This seems to be a common problem with a lot of people right now. You need to downgrade your Android sdk tools to rev 21.1 because rev 22 is what's causing the problem

I haven't tested this yet but I can build find on my laptop and not on my desktop and that's the only difference I can find. Try using this link to install rev 21.1 http://dl.google.com/android/installer_r21.1-windows.exe
