Better implementation of Splash Screen

[samagra14]

Currently, the splash screen is implemented via a dedicated splash activity which is not an optimal way of implementing splash screens. Moreover setting up Firebase and other functionalities in the splash activity is also suboptimal. The correct way of implementing splash screens as stated by Google can be found on the link below :- https://android.jlelse.eu/launch-screen-in-android-the-right-way-aca7e8c31f52 All the networking code should be done in the main activity while showing the progress bar. This is how most of the Google Apps implement splash screen.
