I just installed android studio on linux , configured the SDK and installed the building tools now when I try to sync with gradle or (build the app) it fails and throws this error :
Error:Execution failed for task ':app:mergeDebugResources'. /home/user_name/AndroidStudioProjects/project_name/app/src/main/res/drawable-hdpi/ic_launcher.png: Error: Cannot run program "/home/user_name/Android/Sdk/build-tools/21.1.2/aapt": error=2, No such file or directory Error:Error: Cannot run program "/home/user_name/Android/Sdk/build-tools/21.1.2/aapt": error=2, No such file or directory /home/user_name/AndroidStudioProjects/project_name/app/src/main/res/drawable-hdpi/ic_launcher.png
I tried to change the ' buildToolsVersion ' in my gradle file and it gave me the same error for 21.1.2 , 1 , 0 also.
I had the same issue even after trying out the accepted solution. In my case the gradle build tool version that I've specified was not installed on my debian system. It worked like a charm after I changed the buildToolVersion to the installed version which was (23.0.2)
I solved the problem by running those commands
Ubuntu can't run the aapt on 64 bit before installing this packages
EDIT 19-04-2016 :
Android Studio 2 have the installation guide updated with those packages and bunch more to compile on 64-bit machines correctly
