How to Add Stacktrace or debug Option when Building Android Studio Project

On the Mac version of Android Studio Beta 1.2, it's under

Android Studio->preferences->Build, Execution, Deployment->Compiler

You can use GUI to add these gradle command line flags from

File > Settings > Build, Execution, Deployment > Compiler

For MacOS user, it's here

Android Studio > Preferences > Build, Execution, Deployment > Compiler

like this (add --stacktrace or --debug)

Note that the screenshot is from before 0.8.10, the option is no longer in the Compiler > Gradle section, it's now in a separate section named Compiler (Gradle-based Android Project)

In Android Studios 2.1.1, the command-line Options is under "Build, Execution, Deployment">"Compiler"

What I use for debugging purposes is running the gradle task with stacktrace directly in terminal. Then you don't affect your normal compiles.

From your project root directory, via terminal you can use:

./gradlew assembleMyBuild --stacktrace
