I have a problem with Android Studio 0.2.3.
When I run my project the build stops and appears message that says:
Gradle: Execution failed for
I've had a similar problem occurr when I had both Eclipse, Android Studio and the standalone Android SDK installed (the problem lied where the AVD Manager couldn't find target images). I had been using Eclipse for Android development but have moved over to Android Studio, and quickly found that Android Studio couldn't find my previously created AVDs.
The problem could potentially lie in that Android Studio is looking at it's own Android SDK (found in C:\Users\username\AppData\Local\Android\android-studio\sdk) and not a previously installed standalone SDK, which I had installed at C:\adt\sdk.
Renaming Android Studio's SDK folder, in C:\Users... (only rename it, just in case things break) then creating a symbolic link between the Android Studio SDK location and a standalone Android SDK fixes this issue.
I also used the Link Shell Extension (http://schinagl.priv.at/nt/hardlinkshellext/linkshellextension.html) just to take the tedium out of creating symbolic links.
