just create check null at your code, like this

            if(myAccount!=null){
            setupArrayListInfo(myAccount);

            if(infoAdapter != null){
                infoAdapter.notifyDataSetChanged();
            }

            if(tvUserName != null){
                tvUserName.setText(myAccount.name);
            }

            setImageAvatar(context, myAccount.avata);
            SharedPreferenceHelper preferenceHelper = SharedPreferenceHelper.getInstance(context);
            preferenceHelper.saveUserInfo(myAccount);
        }
