解决方案
说明白点，就是**public class MainActivity extends Activity**和 private class updata extends AsyncTask
这两个类不能同时出现在一个类中，建议你最好分开写。
解决方案二：
Android 编译源码 错误
解决方案三：
把错误提示贴出来看看
解决方案四：
这个问题的直接原因是由于你忘记了 JAVA的一个class不能同时extends两个类，这是属于语法错误，建议你再看下相关的书籍就能搞定。
解决方案五：
提示信息不是说了你的onPostCreate()方法里没有调用父类方法吗？
解决方案六：
android.util.SuperNotCalledException: Activity {com.example.refresh_drawer_demo/com.example.refresh_drawer_demo.MainActivity} did not call through to super.onPostCreate()
这段看明白了吗？
解决方案七：
提示信息不是说了你的onPostCreate()方法里没有调用父类方法吗？
