B4i Library Firebase + Facebook v2.0 - July 2019

Newer version: https://www.b4x.com/android/forum/threads/firebase-2-50-april-2020.116278/
The four Firebase libraries and Facebook library were updated and are now based on the latest versions of the underlying SDKs.


- Download PC-Libraries.zip, unzip it and copy the XML files to the internal libraries folder.
- If using a local Mac then:
1. Download Mac-Wrappers.zip and unzip it in the Mac libs folder.
2. Download the frameworks directly from your Mac and unzip them in the Mac libs folder: www.b4x.com/b4i/files/FirebaseMacFrameworks2.zip

PC-Libraries are only required if using B4i v5.80 or an older version.

Don't download
