fplutil is a set of small libraries and tools that can be useful when developing applications for Android and other platforms.

Download the latest release from the fplutil github page or the releases page.

Important: fplutil uses submodules to reference other components it depends upon so to download the source use:

git clone --recursive https://github.com/google/fplutil.git

Before getting started, make sure all prerequisites are installed and configured.


  • build_all_android is an all-in-one build script that allows you to build, install and run native (C/C++) Android apps from the command line. This is ideal for build automation, but can also be in a developer’s compile/run loop.
  • buildutil performs the configuration, build and archive steps of Android and Linux C/C++ applications using a suite of Python modules. This suite of modules can automate builds in a continuous integration environment.
  • android_ndk_perf is a desktop tool that enables native (C/C++) developers to measure the CPU utilization of their applications on Android, guiding their optimization efforts.
  • libfplutil enables C/C++ developers to write traditional applications (like Hello World) using "main()" and "printf()" on Android.
