小编use*_*445的帖子

这在android 4.0.3上工作得很好,但我在android 2.3.3中得到错误任何帮助将不胜感激.粗体的行抛出错误.

public class TestLoadingTask extends AsyncTask<Object, Object, Void> {
}

btndownload.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        if (util.isNetworkAvailable(NewTakeTest.this)) {
                TestLoadingTask task;
        task = new TestLoadingTask();
        task.currentposition = position;
        task.testname = productsOnCloudList.getList().get(position).getProductname();
        **task.executeOnExecutor(task.THREAD_POOL_EXECUTOR, null);**
    }
    }
});

我是stackoverflow的新手,所以如果我无法正确解释我的问题,请原谅我.

整个日志如下所述.
