Error using ADAL in Android app for Teams
I have developed a SharePoint WebPart that I'm using in Teams. This WebPart obtains, using ADAL, a token to validate the user. This application works fine in Sharepoint, Teams (online & desktop app) but when I try to execute this WebPart inside the Android app for Teams I have this error: I don't know if I need a special certificate in this case... 04-28 13:10:13.913 8456 8763 I OpenGLRenderer: Davey! duration=1870ms; Flags=1, IntendedVsync=187039755963, Vsync=187739755935, OldestInputEvent=9223372036854775807,
