在我的oPhone手机上，执行一个APP，总是报错。
报错的代码如下在：
AsyncTask.execute(new Runnable() {
@Override
public void run() {
//一些后台逻辑代码
}
});
错误信息： java.lang.NoSuchMethodError: android.os.AsyncTask.execute
详细的错误信息如下：

如果把这里的代码修改成下面方式就不会报错了：
new AsyncTask<Integer, Integer, String>() {
@Override
protected String doInBackground(Integer... params) {
// 一些后台线程逻辑代码
return null;
}
protected void onPostExecute(String result) {
};
}.execute(1000);
