How to access the refresh token?

The AuthenticationResult at AuthenticationCallback success only gives the access token. How do we get the refresh token using this implementation?

this example is out of date, please update to latest msal library and android x

Hi team,
this example is out of date, please update to latest msal library and android x #13

Msal Library is taking too much time to throw MSAL exception in Failure case

Please find the log where I have try 2 attempts and it taking more then 2 and 5 min of time to throw the exception in case of failure

Attempt 1
Line 251: 11-26 21:23:36.731
Line 91: 11-26 21:21:03.109
Time Taken by MSAL: 00-00 00:02:33.622

Attempt 1
Line 461: 11-26 21:36:13.927
Line 371: 11-26 21:31:13.689
Time Taken by MSAL: 00-00 00:05:00.238

Is There Any way is there to reduce this time when Msal is throwing the Exception withing 40sec instead of 2 or 5+ minute for the good experience??
Any work arround solution for this from MSAL end
as in 1st attempt the correlation id had not returned in the header of response.So it took 2min.33sec.622ms
as in 2st attempt the Request timeout with SocketTimeoutException and its retry one more time but that Token request failed with error as Connection reset by peer.So it took 5min.0sec.238ms

Log Details start here related to MSAL.

MSAL B2C Authorization on Android

I've sucessfully signed in using "Azure AD B2C" on my android app. But I am not able access my asp.net core web api using the bearer token. The api is returning 401 "UnAuthorized error".

I am able to access the same api from swagger UI and Postman.

I tried to access the api from postman using bearer token received on my mobile. The api returned with the
Bearer error="invalid_token", error_description="The signature key was not found".
MSAL Version: 0.2+ and 0.3+
Any help is greatly appreciated.
