# Install the standard Android SDK licenses. In the past, there wasn't a better way to do this,
# so we are base64-encoding a zip of the licenses directory from another installation.
# To create this base64 string, create a zip file that contains nothing but a 'licenses' folder,
# which folder contains the accepted license files found in 'C:\Program Files (x86)\Android\android-sdk\licenses'.
# Then, run this in PowerShell:
#     $LicensesZipFileName = 'C:\Program Files (x86)\Android\android-sdk\Licenses.zip'
#     $base64Content = [Convert]::ToBase64String([IO.File]::ReadAllBytes($LicensesZipFileName))
#     echo $base64Content
#
# Future: see if the base64 technique can be avoided by running this PowerShell script to accept all licenses.
# This fails when run on a live agent, likely because non-interactive mode is set.
# It may work fine during image generation (this script).
