我知道这com.android.vending是指从Google Play安装.

但是com.google.android.feedback指的是什么？

我需要帮助才能使过滤工作.ListView显示正确,但是当我在搜索字段中输入一个字母时,它会出错

和申请结束.

以下是我的活动中的代码片段,我认为我必须修复,但不知道如何:

    protected void onPostExecute(String file_url) {
        // dismiss the dialog after getting all albums
        pDialog.dismiss();
        // updating UI from Background Thread
        runOnUiThread(new Runnable() {
            public void run() {
                /**
                 * Updating parsed JSON data into ListView
                 * */

                ListAdapter adapter = new SimpleAdapter(

                                TAG_wine_id, TAG_wine_name,
                                TAG_wine_country_id,
                                TAG_wine_country_flag_pic }, new int[] {
                                R.id.wine_id, R.id.wine_name,
                                R.id.wine_country_id, R.id.imageView2 });
                ListView lv = getListView();
                LayoutInflater inflater = getLayoutInflater();
                View header = inflater.inflate(R.layout.header,
                        (ViewGroup) findViewById(R.id.LinearLayoutHeader));
