Android Fabric Twitter和Digits麻烦

Question

i installed Fabric plugin in Android studio. Chose Digits and add some code by suggestions of it. Got this error:

java.lang.NullPointerException: Attempt to invoke virtual method 'void com.digits.sdk.android.DigitsAuthButton.setCallback(com.digits.sdk.android.AuthCallback)' on a null object reference.

So, the problem is here(maybe):

phoneButton.setCallback(new AuthCallback() {
            @Override
            public void success(DigitsSession digitsSession, String phoneNumber) {

            }

            @Override
            public void failure(DigitsException e) {

            }
        });

Also i had same problems with Twitter part of plugin. Any ideas? Thank you for attention.

问题不在于AuthCallback，您的phoneButton对象为null，可能是因为未正确从布局中检索到它。
