android_frameworks_base/cmds/idmap2/tests/Idmap2BinaryTests.cpp
Mårten Kongstad 0275123eef idmap2: initial code drop 
idmap2 is a reboot of the idmap project. The project aims to

  - use modern C++
  - greatly improve test and debug support
  - interface towards AssetManager2 (instead of AssetManager)
  - provide a solid foundation to add support for new features

To make it easier to verify correctness, this first version of idmap2 is
feature equivalent to idmap. Later versions will add support for new
features such as <overlayable>.

Bug: 78815803
Test: make idmap2_tests
