Feature request: Detect installed package versions

[ypsvlq]

Currently wio's examples include 3 build scripts supporting Android, each of which has build options defaulting to what I have installed locally:

const apk = sdk.createApk(.{
    .build_tools_version = b.option([]const u8, "android_build_tools_version", "Android build tools version (e.g. 35.0.0)") orelse "37.0.0",
    .ndk_version = b.option([]const u8, "android_ndk_version", "Android NDK version (e.g. 27.0.12077973)") orelse "29.0.14206865",
    .api_level = b.option(android.ApiLevel, "android_api_level", "Android API level (e.g. android15)") orelse .android15,
});

It would be nice for maintenance and usability if zig-android-sdk could default to the newest installed versions, which could be implemented by iterating the respective SDK directories.

I'm open to it... but I'd prefer if we perhaps just took the approach of automating the installation of the Android tools required. That way users will at least definitely be running the exact same tools/etc as yourself and what was tested.

So ideally a way to attempt to run sdkmanager --install to get any missing Android dependencies.

Example
sdkmanager --install "tools platform-tools" "platforms;android-35 build-tools;35.0.0 ndk;29.0.13113456"

Example location of sdkmanager
~/Android/Sdk/cmdline-tools/latest/bin/

We'd also want something so that a user can just simply accept the sdkmanager license too via:
sdkmanager --licenses

I definitely do not think this should happen automatically, I would not expect running zig build to potentially install software in $ANDROID_HOME. Showing the install commands in error text could be a nice improvement, though.

That way users will at least definitely be running the exact same tools/etc as yourself and what was tested.

This is already possible by passing exact versions to sdk.createApk, I specifically want the behaviour of using the installed tools unless overridden by the user.
