I have added Fabric Digit kit for verifying mobile number. Mobile number is getting verified successfully, but when I click verify button app gets crashed and when I reopen the app, digit session is created successfully, I have used Digit in many apps but not getting what is the issue.May be particular version or else?

Crash Log:

More detailed log is added here from Crashalytics

Code implemented in the app:

onCreate

authCallback = new AuthCallback() {
                    @Override
                    public void success(DigitsSession session, String phoneNumber) {
                        Log.d("msg", "session : " + session.toString() + " " + phoneNumber);
                        MOBILE_NO = phoneNumber;
                        storeUserData.setString(Constants.USER_MOBILE, phoneNumber);
                        Digits.clearActiveSession();
                        startActivity(new Intent(activity, RegisterActivity.class)
                                .setFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
                    }

                    @Override
                    public void failure(DigitsException error) {
                        error.printStackTrace();
                    }
                };

for Verification

binding.authButton.setCallback(authCallback);
                            binding.authButton.setAuthTheme(R.style.CustomDigitsTheme);

                            AuthConfig.Builder authConfigBuilder = new AuthConfig.Builder()
                                    
                                    .withAuthCallBack(authCallback)
                                    .withPhoneNumber("+91");

                            Digits.authenticate(authConfigBuilder.build());

I had the same issue and found that I was clearing the active session (logging out) inside callback methods.

Remove this line:

Digits.clearActiveSession();

Or in my case I removed this line:

Digits.logout();

You can try below code, 

DigitsAuthButton digitsButton;
AuthCallback authcallback;
 digitsButton = (DigitsAuthButton) view.findViewById(R.id.auth_button);
        digitsButton.setAuthTheme(R.style.CustomDigitsTheme);
        authcallback = new AuthCallback() {
            @Override
            public void success(DigitsSession session, String phoneNumber) {
                edtMobNumber.setText(phoneNumber);
            }

            @Override
            public void failure(DigitsException exception) {

                exception.printStackTrace();

            }
        };
        digitsButton.setCallback(authcallback);
//launching digits activity on click of edit text
edtMobNumber.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Digits.clearActiveSession();
        digitsButton.performClick();
    }
});

Let me know if it works for you.
