[vtkusers] Building VTK for Android

[Alexander Novinskiy]

I managed to solved the problem as follows:

I downloaded android command line tools from the official Android Studio web site as an archive.

The archive should be extracted into a folder “tools” which should be placed into android sdk directory.

The android sdk directory will probably already contain a folder “tools”.

One should substitute the default android sdk “tools” with the android command line tools downloaded as a standalone package.

The reason for this is that “tools/android” tool is deprecated in modern Android Studio distributions and doesn’t work as it used to.

I guess this issue should be considered by developers of VTK in order to ged rid of difficulties on the user side since Google doesn’t distribute proper android command line tools with Android Studio any more.
