The search and many features are not working in Android for API near 24

[immadisairaj]

When testing in the Android Emulator for the application in v1.1.1 for the API 24, the search, schedule and other feature that require posting requests to the archived site of sssmediacentre (formerly radiosai) are still in loading state.

This issue might majorly be due to certificate issues either from server or from the device.

Additional Details:
For some reason, the search and a few things work sometimes and doesn't other times. The occurrence of the issue is un predicted as of now. Need to look into more info regarding this issue.
