再次写这个是非常郁闷的，主要怪我，live writter 2011还不支持，辛辛苦苦写了半天，不小心按住了刷新键，结果写的东西全没了，虽然很气愤，虽然手已经冰凉，还是坚持又整理了一遍，也希望51CTO以后能随时保存草稿，这是一个非常严重的问题：

如果你已经在Android Market上发布了应用程序，怎么通过编程方式访问Android Market呢？谷歌大神已经为我们提供好了接口-An open-source API for the Android Market，不仅Android程序可以访问， Ruby 和PHP也提供了借口，更多信息请参考：http://code.google.com/p/android-market-api/

OK，废话少说，That‘s it!

Current progress

You can browse market with any carrier or locale you want.
Search for apps using keywords or package name.
Retrieve an app info using an app ID.
Retrieve comments using an app ID.
Get PNG screenshots and icon

Requirement

*(1) A Google Account
*(2) Include androidmarketapi-X.Y.jar and protobuf-java-X.Y.Z.jar in your classpath,
下载地址：http://code.google.com/p/android-market-api/downloads/list

要把这两个JAR导入到项目中去.由于代码比较好理解，就不添加注释了:-)

HowToSearchApps:

You can search by using :

By package name;

String query = "pname:<package>";

By developper name :

String query = "pub:<name>";

通过包名查看程序关键代码：

1. String query = "pname:com.luckyxmobile.timers4me";// 通过包名查找程序  
2. MarketSession session = new MarketSession();  
3. session.login("your gmail account", "your password");  
4. AppsRequest appsRequest = AppsRequest.newBuilder().setQuery(query)  
5. .setStartIndex(0).setEntriesCount(10).setWithExtendedInfo(true).build();  
6. session.append(appsRequest, new MarketSession.Callback<AppsResponse>() {  
7. @Override 
8. public void onResult(ResponseContext context, AppsResponse response) {  
9. TextView text = (TextView) findViewById(R.id.text);  
10. String id = response.getApp(0).getId();  
11. String creatorID = response.getApp(0).getCreatorId();  
12. String creator = response.getApp(0).getCreator();  
13. String packageName = response.getApp(0).getPackageName();  
14. String price = response.getApp(0).getPrice();  
15. String rating = response.getApp(0).getRating();  
16. int ratingCount = response.getApp(0).getRatingsCount();  
17. String title = response.getApp(0).getTitle();  
18. String version = response.getApp(0).getVersion();  
19. int versionCode = response.getApp(0).getVersionCode();  
20. int serializedSize = response.getApp(0).getSerializedSize();  
21. ExtendedInfo extendedInfo = response.getApp(0).getExtendedInfo();  
22. text.setText("id:" + id + "\nCreatorId:" + creatorID  
23. + "\nCreator:" + creator + "\nPackageName:" 
24. + packageName + "\nPrice:" + price + "\nrating:" 
25. + rating + "\nRatingCount:" + ratingCount + "\ntitle:" 
26. + title + "\nVersion:" + version + "\nversionCode:" 
27. + versionCode + "\nDownloadsCount:" 
28. + extendedInfo.getDownloadsCount()  
29. + "\nDownloadsCountText:" 
30. + extendedInfo.getDownloadsCountText()  
31. + "\nInstallSize:" + extendedInfo.getInstallSize()  
32. + "\nSerializedSize:" + serializedSize  
33. + "\nDecription:" + extendedInfo.getDescription()  
34. + "\nContactEmail:" + extendedInfo.getContactEmail()  
35. + "\nContactPhone:" + extendedInfo.getContactPhone()  
36. + "\nContactWebsite:" 
37. + extendedInfo.getContactWebsite());  
38. }  
39. });  
40. .flush();//发送并刷新

运行结果：

HowToGetAppComments

1. CommentsRequest commentsRequest = CommentsRequest.newBuilder().setAppId("7065399193137006744") .setStartIndex(0).setEntriesCount(10)build();         
2. session.append(commentsRequest, new Callback<CommentsResponse>() {   
3. @Override      
4. public void onResult(ResponseContext context, CommentsResponse response) {    
5. System.out.println("Response : " + response);      
6. // response.getComments(0).getAuthorName()       
7. // response.getComments(0).getCreationTime()       
8. // ...      
9. } });   
10. session.flush();

HowToGetAppScreenshot

1. GetImageRequest imgReq = GetImageRequest.newBuilder().setAppId("-7934792861962808905").setImageUsage(AppImageUsage.SCREENSHOT).setImageId("1").build();       
2. session.append(imgReq, new Callback<GetImageResponse>() {                                                       
3. @Override         
4. public void onResult(ResponseContext context, GetImageResponse response) {  
5. try {                                                
6. FileOutputStream fos = new FileOutputStream("icon.png");                                   
7. fos.write(response.getImageData().toByteArray());                                        
8. fos.close();                                  
9. } catch(Exception ex) {                           
10. ex.printStackTrace();                                       
11.   }        
12. } });   
13. session.flush();

最后提醒一下哦，不要忘记在配置文件中加上访问Internet的权限，当然了，我只是抛砖引玉的作用，动手才能更加精彩，Good luck！
