On press back button device hang.

I am using this app for first time logging. Call Connect() function for signing. private void connect() {

    // The sample app is having the PII enable setting on the MainActivity. Ideally, app should decide to enable Pii or not,
    // if it's enabled, it should be  the setting when the application is onCreate.
    if (mEnablePiiLogging) {
        Logger.getInstance().setEnablePII(true);
    } else {
        Logger.getInstance().setEnablePII(false);
    }

    AuthenticationManager mgr = AuthenticationManager.getInstance();

      /* Attempt to get a user and acquireTokenSilent

• If this fails we do an interactive request */ List users = null;

  try {
      users = mgr.getPublicClient().getUsers();
  
      if (users != null && users.size() == 1) {
    /* We have 1 user */
          mUser = users.get(0);
          mgr.callAcquireTokenSilent(
                  mUser,
                  true,
                  this);
      } else {
    /* We have no user */
  
    /* Let's do an interactive request */
          mgr.callAcquireToken(
                  this,
                  this);
      }
  } catch (MsalClientException e) {
      Log.d(TAG, "MSAL Exception Generated while getting users: " + e.toString());
      showConnectErrorUI(e.getMessage());
  
  } catch (IndexOutOfBoundsException e) {
      Log.d(TAG, "User at this position does not exist: " + e.toString());
      showConnectErrorUI(e.getMessage());
  
  }catch (IllegalStateException e) {
          Log.d(TAG, "MSAL Exception Generated: " + e.toString());
          showConnectErrorUI(e.getMessage());
  
  } catch (Exception e) {
      showConnectErrorUI();
  }

  }

from this function it call. public void callAcquireToken(Activity activity, final MSALAuthenticationCallback authenticationCallback) { mActivityCallback = authenticationCallback; mPublicClientApplication.acquireToken( activity, Constants.SCOPES, getAuthInteractiveCallback()); } after calling this function i get signing page.

after that i click on back button which appear on signing page. when i click back button device hang after some time get message of not responding. Device back button work perfect but authetication back button is not working .

Interesting problem. Honestly, I haven't spent a lot of time writing tests for your exact scenario. I'll investigate this and update this issue with my findings.
