java - THREAD_POOL_EXECUTOR 在 2.3 android 模拟器中崩溃

Question

我必须在 AsynTask 中使用 THREAD_POOL_EXECUTOR 并且我知道它属于 API 11 及更高版本。我用这段代码检查了它:

                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，我在 THREAD_POOL_EXECUTOR 周围出现错误!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？我该如何修复它？

更新:整个 logcat:

Answer 1

这只是一个警告，您可以忽略它。

Dalvik 类加载器发现对缺失字段的引用并发出警告。上面的 SDK_INT 条件可防止该部分代码在 Honeycomb 之前运行。

(HONEYCOMB 常量是一个 static final 原语，在编译时内联，不需要在类加载时解析。)
