Cannot configure Android project

Describe the bug Base on your documentation at this page https://docs.aws.amazon.com/lumberyard/latest/userguide/android-intro.html is not possible to configure Android project. As I think it's because Google make some changes with their API (or Android Studio Team). Also there is a few mismatches between your documentation and used configuration.

Steps to reproduce

Set "Compile for Android devices" in Setup Assistant,
lmbr_waf configure and you will get error similiar to this one from logs (see logs).

Expected behavior Sucessfully generated VS solution with Android dependencies and compiled Android project.

Lumberyard version 1.23.1

Suggested solution

Update documentation (to use NDK r21, to check Android envirionment variables, provide exactly version numers eg. 29.0.1 etc.),
Update android.settings.json to use Android 21 SDK (I created pull request 470 for it). Please consider to replace "latest" for BUILD_TOOL_VERSION for specified one,
The problem is at tools at Android SDK - thats their update as I think. At the moment Tools are replaced by Android SDK Command-line Tools (at dafault located in cmdline-tools of Android SDK folder). Libraries required by Lumberlyard ( manifest-merger.jar, sdk-common.jar, common.jar) are at their subfolders (build-system, common, sdk-common ). So you should change WAF configuration file to get it from valid place (or I hope you will do it in cmake in next release).

I hope that will help you :)
