依据上述代码解决FanHui.java中的报错：Cannot resolve symbol 'mAppKey' Cannot resolve symbol 'KEY_APPKEY' Cannot resolve symbol 'mDeviceSerial' Cannot resolve symbol 'KEY_SERIAL' Cannot resolve symbol 'mVerifyCode' Cannot resolve symbol 'KEY_VERIFYCODE' Cannot resolve symbol 'mAccessToken' Cannot resolve symbol 'KEY_ACCESSTOKEN' Cannot resolve symbol 'mCameraNo' Cannot resolve symbol 'KEY_CAMERANO' Cannot resolve symbol 'mAppKey' Cannot resolve symbol 'mDeviceSerial' Cannot resolve symbol 'mVerifyCode' Cannot resolve symbol 'mAccessToken' Cannot resolve symbol 'mCameraNo'
本文解决了一个常见的编程问题：包导入错误。通过添加一行代码：import android.os.Handler; 该问题得到了有效解决。
