AsyncTask只适用于调试？

Question

奇怪的事发生了.我有一个AsyncTask运行,所以我不在UI上获取数据库数据Thread.这是我的任务:

ProductListActivity.java:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_product_list);
    if (savedInstanceState == null) {
        new QueryProductsTask(this).execute();
    }
}

public void populateProductList(Cursor products) {
    ProductListAdapter productListAdapter =
            new ProductListAdapter(this, R.layout.product_list_row, products);
    ListView listView = (ListView) findViewById(android.R.id.list);
    listView.setAdapter(productListAdapter);
}

QueryProductsTask.java:

protected Cursor doInBackground(Void... params) {
    android.os.Debug.waitForDebugger();
    Log.v("BagIt.AsyncTask", "doInBackground running");
    // Fetches info from database:
    return new Products(activity.getBaseContext()).select(null, null, null, null);
}

protected void onPostExecute(Cursor c) {
    android.os.Debug.waitForDebugger();
    Log.v("BagIt.AsyncTask", "onPostExecute running");
    // Populates ListView through a custom adapter
    activity.populateProductList(c);
}

当我处于调试模式时,此代码可以正常工作.Adapter就我现在所知,或者Db类没有任何错误.但是,当我在手机上打开应用程序,或点击"运行"而不是"调试"时,它不起作用.即使我在没有任何断点的情况下进行调试,它也会运行,但不会在调试模式之外.

这是我的logcat:

你可以看到Log.v()s正常工作(最后几行)

等到调试器附加.

删除该行将允许它在没有连接调试器时运行.
