Problem getting SDK version from semver.from(sdk.default_build_tools_version) about vab

[Larpon]

On my Debian Bullseye this doesn't work as the value of sdk.default_build_tools_version appears to be "debian" at this point.

Have installed debian package android-sdk-platform-23, android-sdk and android-sdk-build-tools , for example aapt is /usr/lib/android-sdk/build-tools/debian/aapt - so I guess there is a problem getting the version from this.

Yes, the Android SDK is an absolute mess in this regard also - with no standards or guideline to where people can place things and how they should name stuff. I remember some other parts of vab had this problem.

Maybe this version check could be disabled altogether? Don't think too many developers will try to use this with some ancient version. BTW, I have a mixed 64/32 bit installation on my elderly laptop which is an interesting testcase for many things.

Disabling it will unfortunately break the --build-tools option since it uses the directory names as version numbers (used by recent SDKs - that hopefully won't change any time soon) - but I can maybe add a check

@xandro0777 - can you please post the output of ./vab doctor - this issue should have been fixed long ago?
What version of vab are you using? Try updating vabvia git and build it again and try again.

./vab doctor will help us greatly since I can see how your setup looks like

[xandro0777]

Just updated v and cloned a fresh copy of vab in a separate directory and built it:

$ vab doctor
No "sdkmanager" could be detected.

You can set the SDKMANAGER env variable or try your luck with `vab install auto`.

Versioning Scheme
=================

The versions of the SDK, the Build-tools and the Platform-tools are independent
from each other, and we track the versions in the following places:

  * SDK: https://android.googlesource.com/platform/tools/buildSrc/+/gradle_${latest}/base/version.gradle
  * Build-tools: https://android.googlesource.com/platform/development/+/android-${latest}/sdk/build_tools_source.prop_template
  * Platform-tools: https://android.googlesource.com/platform/development/+/android-${latest}/sdk/plat_tools_source.prop_templaterz@rz-debian:~/prog/ui/examples

@xandro0777 - it was a little more tricky than first anticipated since the filtering of unknown versions was also broken (someone forgot to assign the result of the filtering ahem 😅 ). So this was a result of several bugs.

Nice catch.

I've tried fixing it by allowing "exotic" build-tool versions in dbf8173 - they're now allowed but has the lowest priority when sorted in case there's more than one "type" of version detected.
