// These are collection of tools and libraries that are required to build
// an apk by the test. This zip file is extracted by the test and files
// in the zip are executed from there.
//
// There are two tricks used here: 1) host tools such as aapt2 are listed
// in the `tools` property although they technically are inputs of the zip,
// not the tools for creating the zip. However, since the java test is not
// specific to arch, it can't (transitively) depend on arch-specific (x86)
// host tools. To work-around the problem, they are listed in the `tools`
// property, and then used as inputs in the `cmd`.
//
// 2) signapk and libconscrypt_openjdk_jni are listed in the `host_required`
// property instead of `tools` or `srcs`. This is because those modules are
// neither specific to arch (thus can't be in tools), nor provide source (thus
// can't be in srcs). To access them, their location in the soong intermediate
// directory is manually searched in the cmd, while dependencies to them are
// created using the `required` property.
