Right now, because Grade and the Grade wrapper (Graders) are configured in the background, you must use the “android” task to do so. The “android” task has a “check-in” phase and a “check-out phase,” which make sure all dependencies are present and start the execution. To start the task, use Task > Start Task > Android Application from the Android Application menu. (If you want to execute an app you've created to the device, you can now use Task > Run Task to run your modified project; you can also start the task from a remote computer using an app like Remote Task Runner or the Grade command line tool. See .) The “check-in” phase, which does all the setup, is part of the “included build tools” phase of the build. When built, the “included build tools” phase also contains a set of build steps that help build the code base. These build steps include building all external packages listed in Google's Android Studio > Build Paths and Android Studio > Packages as well as building the “app” project. The “check-out” Phase When the package system is synchronized, the “check-out” phase runs when an app is installed on an Android Device or when you download an app from Google Play. The “check out” phase also includes all the build-time actions and tasks that would have occurred were the app not installed, including provisioning your device. The check-out phase starts after your Android device has booted and checks to see whether it has an app. All code built during the build-time actions such as compiling, running tests, and deploying an app to a device will go into the “check out” phase. The check-out phase takes place after the app and the necessary dependencies are installed to your device. When you start a new Android Studio project, it is always in the check-in phase. You can run the “check-out” phase and all build-time tasks and actions that are related to it on the Grade console by selecting Edit > Run > Check In.
