嵌套类AsyncTask无法修改外部类静态对象

public interface AsyncTaskCallback {
    void onModifyStaticObject();
}

public class OuterClass {
    private static Object staticObject;
    private static AsyncTaskCallback callback;

    public static void setCallback(AsyncTaskCallback callback) {
        OuterClass.callback = callback;
    }

    public static void modifyStaticObject() {
        if (callback != null) {
            callback.onModifyStaticObject();
        }
    }
}

public class MyAsyncTask extends AsyncTask<Void, Void, Void> {
    @Override
    protected Void doInBackground(Void... voids) {
        // 执行异步任务的逻辑

        // 修改外部类的静态对象
        OuterClass.modifyStaticObject();

        return null;
    }
}

OuterClass.setCallback(new AsyncTaskCallback() {
    @Override
    public void onModifyStaticObject() {
        // 在回调函数中修改外部类的静态对象
        OuterClass.staticObject = newValue;
    }
});

MyAsyncTask task = new MyAsyncTask();
task.execute();
