Google Play does not provide any official APIs for retrieving metadata. You could however, check the unofficial API at http://code.google.com/p/android-market-api/.
Specifically, take a look at the Wiki page [HowToSearchApps](http://code.google.com/p/android-market-api/wiki/HowToSearchApps). The response to the query contains version information:
{ "app": [ { "rating": "4.642857142857143", "title": "Ruboto IRB", "ratingsCount": 14, "creator": "Jan Berkel", "appType": "APPLICATION", "id": "9089465703133677000", "packageName": "org.jruby.ruboto.irb", "version": "0.1", "versionCode": 1, "creatorId": "\"Jan Berkel\"", "ExtendedInfo": { "category": "Tools", "permissionId": [ ...

Specifically, take a look at the Wiki page [HowToSearchApps](http://code.google.com/p/android-market-api/wiki/HowToSearchApps). The response to the query contains version information:
**Your query will be something like:**
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) { // Your code here // response.getApp(0).getCreator() ... // see AppsResponse class definition for more infos } });
**Your response will be of the format:**
{ "app": [ { "rating": "4.642857142857143", "title": "Ruboto IRB", "ratingsCount": 14, "creator": "Jan Berkel", "appType": "APPLICATION", "id": "9089465703133677000", "packageName": "org.jruby.ruboto.irb", "version": "0.1", "versionCode": 1, "creatorId": "\"Jan Berkel\"", "ExtendedInfo": { "category": "Tools", "permissionId": [ ...
**Then of course you may use a JSON Parser or do a string search.**
