migrate to GitHub actions

[techno-disaster]

Is your feature request related to a problem? Please describe. Currently we use Github actions to build on every PR and create a artifact where the testing team can download it to test the changes. We also use travis CI for building a apk and pushing it to the apk branch after every push to the develop branch.

Describe the solution you'd like We should remove travis ci as we have exceded the quota and migrate that pipeline to github actions
