The ANDROID_HOME ist set but InteliJ does not seem to find it.

Answer 1

Set the sdk.dir in a local.properties file by running the following in your project's root dir:

$ android update project -p .

Setting up a local.properties file is a solution that will work for most IDEs since you don't need to worry about getting environment variables passed around.

I got this from Unable to find Android SDK . There are also few other options which you may try.

Answer 2

• Go to Run Configurations (Run -> EditConfigurations..)
• Select your test from the left hand side (under JUnit)
• In the configurations tab, go to Environment Variables section and add an environment variable ANDROID_HOME pointing to your sdk
• Apply, build and run the test again

Note : You can add this in the JUnit default settings, so that you don't have to do for each test class
