Not entering into the jitsi room

Use pre-build SDK artifacts/binaries for setup jitsi meet in an android app.
Use the same MainActivity class that is mentioned in the GitHub document. Also, set the room URL as “” for testing. When we test the app, it will redirect to the JitsiMeetActivity and always display the white screen and showing loading icon. Always loading the screen. Not enter into the video conferencing room Please help…!..Thanks…
