如何使用非官方 Android Market API？

我正在尝试来自的示例代码here。但我的应用程序崩溃了。

我添加了日志记录，发现它崩溃了session.flush();所以我删除了那条线，它不再崩溃了。

但还没有达到onResult打回来。

package com.mytest.app;

import com.gc.android.market.api.MarketSession;
import com.gc.android.market.api.MarketSession.Callback;
import com.gc.android.market.api.model.Market.AppsRequest;
import com.gc.android.market.api.model.Market.AppsResponse;
import com.gc.android.market.api.model.Market.ResponseContext;

import android.app.Activity;
import android.os.Bundle;
import android.provider.Settings.Secure;
import android.util.Log;

public class MarketAPITestActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Log.d("Market API", "Started");

        String email = "[email protected]";
        String pass = "mypass";
        String AndroidId = Secure.getString(this.getContentResolver(), Secure.ANDROID_ID);

        MarketSession session = new MarketSession();
        session.login(email,pass);
        session.getContext().setAndroidId(AndroidId);

        String query = "maps";
        AppsRequest appsRequest = AppsRequest.newBuilder()
                                        .setQuery(query)
                                        .setStartIndex(0).setEntriesCount(10)
                                        .setWithExtendedInfo(true)
                                        .build();

        session.append(appsRequest, new Callback<AppsResponse>() {
                 @Override
                 public void onResult(ResponseContext context, AppsResponse response) {
                        Log.d("Market API", "Got response");
                 }
        });

        session.flush();                        
    }
}

有一个问题androidId。代替：

String AndroidId = Secure.getString(this.getContentResolver(), Secure.ANDROID_ID);

用这个：

String AndroidId = "dead000beef";

有用。
