Android 2.3.3 AsyncTask call raises NoSuchFieldError

this works fine on Android 4.0.3, but I get an error in android 2.3.3 any help would be greatly appreciated. a line in bold causes an error.

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);**
    }
    }
});

I am new to stackoverflow, so if I cannot correctly explain my question, please forgive me.

, API 11 , API 10 . executeOnExecutor() THREAD_POOL_EXECUTOR API 11 Android. android.os.Build Android, , execute() .

:

  @TargetApi(11)
  static public <T> void executeAsyncTask(AsyncTask<T, ?, ?> task,
                                          T... params) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
      task.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, params);
    }
    else {
      task.execute(params);
    }
  }

, AsyncTask executeAsyncTask(), AsyncTask , doInBackground() :

fooTask=new FooTask();
executeAsyncTask(fooTask, "these", "are", "optional");
