我必须在 AsynTask 中使用 THREAD_POOL_EXECUTOR，我知道它属于 API 11 及更高版本。用这段代码我检查了它：

                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
                    new init().executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
                } else {
                    new init().execute();
                }

但是当我在 2.3 设备中运行我的应用程序时，我收到关于 THREAD_POOL_EXECUTOR 的错误！在上面的代码中我说没有必要在 2.3 设备上运行它！我收到此错误：

10-04 14:00:26.914: W/dalvikvm(728): VFY: unable to resolve static field 33 (THREAD_POOL_EXECUTOR) in Landroid/os/AsyncTask;

那是什么？我该如何解决？

更新：整个logcat：

这只是一个警告，您可以忽略它。

Dalvik 类加载器找到了对缺失字段的引用并发出警告。上面的SDK_INT条件阻止了这部分代码在 pre-Honeycomb 上运行。

（HONEYCOMB常量是static final在编译时内联的原语，不需要在类加载时解析。）
