8. When done, follow the steps in [Readme.md](Readme.md#installation-on-android) to compile and deploy the application.
## Setting up the SDK Tools
1. In `Source/Android`, create a file called `local.properties`.
2. Add a single line: `sdk.dir=<sdk-path>`, where `<sdk-path>` is the path where you extracted the SDK Tools package.
3. Follow the steps in [Readme.md](Readme.md#installation-on-android) to compile and deploy the application.

Most dependencies for the Android project are supplied by Gradle automatically. However, Android platform libraries (and a few Google-supplied supplementary libraries) must be downloaded through the Android package manager.

1. Launch the Android SDK Manager by clicking on its icon in Android Studio's main toolbar:
![Android Studio Package Icon][package-icon]
2. At the bottom of the window, click "Deselect All", and then "Updates".
3. Install or update the following packages:
* SDK Platform, under "Android 5.0.1 (API 21)". This will allow compiling apps that target Lollipop.
* Android Support Repository
* Android Support Library
* Google Repository
2. Install or update the SDK Platform. Choose the API level selected as [compileSdkVersion](Source/Android/app/build.gradle#L5).
3. Install or update the SDK Tools. CMake, LLDB and NDK. If you don't use android-studio, please check out https://github.com/Commit451/android-cmake-installer.
In the future, if the project targets a newer version of Android, or use newer versions of the tools/build-tools packages, it will be necessary to use this tool to download updates.

If you prefer, you can run the CMake step manually, and it will copy the resulting
binary into the correct location for inclusion in the Android APK.

install the application onto a connected device. If other ABIs are eventually supported,
execute the tasks corresponding to the desired ABI.
