[adityastic]

Tasks:

• Write Basic Pipeline in Github Actions #743 - Write Basic Pipeline ( @adityastic )
• Change Required Check from Travis to Github CI ( @iamareebjamal )
• Shift Secrets from Travis to Github Actions ( @iamareebjamal )
• - Add Deployment Pipeline based on the secrets ( @adityastic )

@iamareebjamal let me know whenever you're done with shifting secrets, if possible also share the screenshot so I can map it to the exact variable

We cannot see Travis variables so have to regenerate and re-encrypt the files

@adityastic There are no variables entered. I am unclear what is required to be added.

@mariobehling apparently the project does not build anymore due to android moving fast and gradle deprecating. I started the migration on my local machine but haven't gotten time to finish it yet. Once the project builds, I'll replicate it on github ci when I will have to set up secrets/env vars to be used by the project.
