# Install the standard Android SDK licenses. Currently, there isn't a better way to do this,
# so we are base64-encoded 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
# Another possible solution that works in powershell core:
# Write-Ouptut "y" | $sdkManager <packagename>
