I am running Android Studio 1.3.2 on Ubuntu 14.04, with build-tools version 23.0.0.
Whenever I load any project, after the indexing is complete, Gradle shows Gradle Bui
I had similar problem. Changing buildToolsVersion in build gradle file worked for me.
sudo apt-get install lib32z1
This dependency was missing in my Ubuntu.. Got it fixed after installing it
I managed to solve the problem after a lot of trial and error.
sudo apt-get install lib32stdc++6
sudo apt-get install lib32z1
These solved the problem for me.
