I've installed android studio on a ubuntu 16.04 via umake, at first it worked properly, but, for some reason i can't explain, everytime I open the IDE, it shows me an error, something like:
NullPointerException: Unexpected exception during symbol building (rebuildModuleMaps)
or sometimes the error message is:
NullPointerException: Unexpected exception during symbol building (rebuildSymbols)
I think it's something with the gradle, but I don't know how to fix it,and can't find anything online.
