Examples:

Running AndroidLint with its basic configuration


android_lint.lint

Running AndroidLint with a specific gradle task


android_lint.gradle_task = "lintMyFlavorDebug"
android_lint.lint

Running AndroidLint without running a Gradle task


android_lint.skip_gradle_task = true
android_lint.lint

Running AndroidLint for a specific severity level and up


# options are ["Warning", "Error", "Fatal"]
android_lint.severity = "Error"
android_lint.lint
