Update your build settings

The following sections describe how to integrate the Tuning Fork library into your toolchain and how to use the functions that the library provides. The library is available as a static or shared library in the AGDK Libraries.

After you've downloaded the SDK to your machine and checked it into your source control system, make the changes listed in the following sections to your project's build settings.

Before you begin

You should integrate the Android Frame Pacing library before integrating the Tuning Fork library. If you do this, the Tuning Fork library can automatically record frame time; there is no need to explicitly call the tick functions yourself.

See the following integration guides for more information:

• Integrate Android Frame Pacing into your OpenGL renderer
• Integrate Android Frame Pacing into your Vulkan renderer

Static library

To link your project to the static library, do the following:

1. Add gamesdk/include to your compiler include paths.

2. Add a path of the following form in your linker library paths:

   gamesdk/libs/architecture_APIapiLevel_NDKndkVersion_stlVersion_Release
   

   Look in gamesdk/libs and pick the one that best suits your toolchain (for example, gamesdk/libs/arm64-v8a_API24_NDK17_cpp_static_Release).

3. Add -ltuningfork_static to your linker command (and -lswappy_static if you integrated the Android Frame Pacing library).

4. Add the INTERNET permission to your AndroidManifest.xml file:

   <uses-permission android:name="android.permission.INTERNET" />
   

Shared library

The steps in the static library section statically link against a version of the Tuning Fork library compiled for the given ABI, API level, NDK, and STL combination. If the combination is not available for your settings, you can instead link against the shared library:

1. Add gamesdk/include to your compiler include paths.

2. Add a path of the following form in your linker library paths:

   gamesdk/libs/architecture_APIapiLevel_NDKndkVersion_stlVersion_Release/lib/tuningfork
   

3. Add -ltuningfork to your linker command (and -lswappy if you integrated the Android Frame Pacing library).

4. Add the INTERNET permission to your AndroidManifest.xml file:

   <uses-permission android:name="android.permission.INTERNET" />
   

Static linking gives you a much smaller code footprint as you don't need to bundle the libtuningfork.so shared library.

Using CMake (static library only)

If you are using CMake, see the gamesdk/samples/tuningfork/insightsdemo/app/CMakeLists.txt file for an example CMake configuration. It includes a utility file, gamesdk/samples/gamesdk.cmake, which performs final checks, adds the proper compiler include paths, and generates a target that you can use to link the library.

To use this utility, do the following:

1. Include this file in your CMakeLists.txt file: include("path/to/gamesdk/samples/gamesdk.cmake")
2. Call the add_gamesdk_target function with the folder containing the gamesdk: add_gamesdk_target(PACKAGE_DIR path/to/gamesdk)
3. In your target_link_libraries for your native library, add tuningfork as a dependency (and swappy if you integrated the Android Frame Pacing library): target_link_libraries(native-lib swappy tuningfork ...)

For advanced usage of CMake, see the gamesdk.cmake source file.
