Update dependencies versions and make neccessary changes afterwards

[rahul-gill]

To use the android libraries which are not added as dependencies in the app right now(e.g. constraint layout), We'll have to find the version of the library which is compatible with the libraries included in the app.

Why

Because latest version of the new dependencies introduces latest version of other libraries like core-ktx and app-compat as transitive dependencies which require updating Gradle and Kotlin versions and updating the compileSdk of the app.
