Android Studio fails to build new project, timed out while wating for slave aapt process

Question

I've installed Android Studio 1.2, and created a new project. When I attempt to build, it hangs. This is in the Gradle Console, along with about 20 other copies, with different numbers after png-cruncher_:

Exception in thread "png-cruncher_2" java.lang.RuntimeException: Timed out while waiting for slave aapt process, try setting environment variable SLAVE_AAPT_TIMEOUT to a value bigger than 5 seconds

Answer 1

I had the same problem with Debian Jessie for AMD64. I did this, and it works:

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libncurses5:i386 libstdc++6:i386 zlib1g:i386

Answer 2

I had the same issue whilst running Android Studio 1.5.1 for Windows 8.1 (64 bit), and what I did to solve the problem was by adding the following two system environment variables:

SLAVE_AAPT_TIMEOUT = 30
JAVA_HOME = C:\Program Files\Java\jdk1.8.0_65

(Please note: The path for the JAVA_HOME system environment variable is dependant on where your JDK is located and that the version of your JDK may differ from the example above).

Answer 3

I had this problem on Windows 8.1 64 bits and what ended up solving everything was running gradle in the command line in debug mode, on the project folder:

gradlew -d assembleDebug

Running without the -d flag had the same problem.

After running the first time, everything was ok, I could even clean and rebuild my project.

Answer 4

I had this problem and what was missing were a library to be installed on the SDK. Just installing the correct library immediately solved the problem. In my case was the Android Support Library, as I was creating a navigation drawer. The errors shown in the gradle console didn't give me a clue for the solution, and didn't helped me at all. Click on SDK manager, and click on the tab SDK Tools, check "Android Support Library" and click apply.
