Response Code 2001 (BROWSER_CODE_CANCEL) when trying to call authentication Users via Azure AD

Hi all,

I got an error code: 2001  (BROWSER_CODE_CANCEL)  when i'm trying to use following code

    mAuthContext= new AuthenticationContext(Login.this, Constants.AUTHORITY_URL,
false, InMemoryCacheStore.getInstance());

mAuthContext.acquireToken(Login.this, Constants.RESOURCE_ID, Constants.CLIENT_ID,
            Constants.REDIRECT_URL, Constants.USER_HINT, PromptBehavior.Auto, Constants.EXTRA_QP,
new AuthenticationCallback<AuthenticationResult>() {

private static final String TAG = "LoginActivity";

@Override
public void onError(Exception ex) {
if (ex instanceof AuthenticationException) {
                        Log.d(TAG, ex.getMessage());
                    } else {

                        Log.d(TAG, "Authentication error:" + ex.getMessage());
                    }
                }

@Override
public void onSuccess(AuthenticationResult result) {
if (result == null || result.getAccessToken() == null
|| result.getAccessToken().isEmpty()) {                      

                        Log.d(TAG, "Token is empty");
                    } else {
// request is successful
Log.d(TAG, "Status:" + result.getStatus() + " Expired:"
+ result.getExpiresOn().toString());                        
                    }
                }
            }
    );
}
