크래시가 난 부분 코드가

webView.getSettings().setSaveFormData(KakaoSDK.getAdapter().getSessionConfig().isSaveFormData());

이 부분인데요.혹시 SDK를 초기화할 때 KakaoSDK.init() 메소드에 넘겨주신 KakaoAdapter 클래스의 코드를 붙여주실 수 있나요? getSessionConfig()가 혹시 null을 리턴하는건 아닌가 생각되어서요.

그리고 KakaoSDK.init() 메소드는 Application의 onCreate() 메소드 같이 프로세스가 실행될 때 항상 불리는 것이 보장되는 곳에서 불려야 합니다. SDK에서 로그인되어 있는 상태에서는 백그라운드에서도 이 어뎁터를 사용하거든요. 이 부분도 한번 체크해 보시겠어요?
