This documents contains instructions for setting up the required configuration of various things such as Facebook app, Firebase project & more before you actually proceed with installation.
Before starting with either of server side or Android configuration, you will need a few things set up.

Prerequisites

On development machine, you must have at least below tools available:
  1. 1.
    Latest Android Studio with latest Command-line Tools.
  2. 2.
    Oracle's JDK 1.8 or newer.
  3. 3.
    Have a Privacy Policy and Terms of Use for your app hosted elsewhere e.g., Google Sites.

Signing keystore

You need to have a keystore to setup a Facebook app and a Firebase project before anything else. There's a YouTube video on https://bit.ly/muly-keystore-hash which you can follow to do this easily.
If you want to do that without the video instructions, please navigate to JDK's bin directory (typically C:\Program Files\Java\jdk-xxx\bin), open a command prompt there and run below command. Make sure to replace yourapp with your application short name (with no symbols and spaces).
1
# make a note of the password you enter below
2
keytool -genkey -v -keystore "%USERPROFILE%/Desktop/release.jks" -deststoretype JKS -keyalg RSA -keysize 2048 -validity 10000 -alias muly
3
​
4
# make note of the SHA-1/256 from release & debug certificate
5
​
6
# password for release is what you chose above
7
keytool -list -v -alias muly -keystore "%USERPROFILE%/Desktop/release.jks"
8
​
9
# password for debug keystore is: android
10
keytool -list -v -alias androiddebugkey -keystore "%USERPROFILE%/.android/debug.keystore"
11
​
Copied!
