Android Studio uses Gradle to compile and build your app. There is a <code>build.gradle</code> file for each module of your project, as well as a <code>build.gradle</code> file for the entire project.

** <code>compiledSdkVersion</code> is the platform version against which you will compile your app. By default, this is set to the latest version of Android available in your SDK. (It should be Android 4.1 or greater; if you don't have such a version available, you must install one using the [[SDK Manager]].) You can still build your app to support older versions, but setting this to the latest version allows you to enable new features and optimize your app for a great user experience on the latest devices. | ** <translate><!--T:19--> | ||

This prints a list of the available Android platforms that you’ve downloaded for your SDK. Find the platform against which you want to compile your app. Make a note of the target ID. We recommend that you select the highest version possible. You can still build your app to support older versions, but setting the build target to the latest version allows you to optimize your app for the latest devices. If you don't see any targets listed, you need to install some using the Android SDK Manager tool.
