How to filter installed Games on Android only?

Question

Here it is described, how to get a list of all installed apps on Android by using the PackageManager.

I would like to get this complete list, filtered by all installed "Games". How can I filter all installed apps for category "Games"

Answer 1

You need to parse each app web page to get its genre then sperate games genres from apps genres.

you could use Jsoup Java HTML Parser and here is a sample code

public class MainActivity extends AppCompatActivity {

public final static String GOOGLE_URL = "https://play.google.com/store/apps/details?id=";
public static final String ERROR = "error";

...


   private class FetchCategoryTask extends AsyncTask<Void, Void, Void> {

       private final String TAG = FetchCategoryTask.class.getSimpleName();
       private PackageManager pm;
       private ActivityUtil mActivityUtil;

       @Override
       protected Void doInBackground(Void... errors) {
          String category;
           pm = getPackageManager();
           List<ApplicationInfo> packages = pm.getInstalledApplications(PackageManager.GET_META_DATA);
           Iterator<ApplicationInfo> iterator = packages.iterator();
           while (iterator.hasNext()) {
               ApplicationInfo packageInfo = iterator.next();
               String query_url = GOOGLE_URL + packageInfo.packageName;
               Log.i(TAG, query_url);
               category = getCategory(query_url);
               // store category or do something else
           }
           return null;
        }


        private String getCategory(String query_url) {
           boolean network = mActivityUtil.isNetworkAvailable();
           if (!network) {
               //manage connectivity lost
               return ERROR;
           } else {
               try {
                   Document doc = Jsoup.connect(query_url).get();
                   Element link = doc.select("span[itemprop=genre]").first();
                   return link.text();
               } catch (Exception e) {
                   return ERROR;
               }
           }
        }
    }  
}

you will find something like

<a class="r2Osbf" href="/store/apps/category/GAME_RACING" title="Racing">Racing</a>
...
"applicationCategory":"GAME_RACING"

So if the category contains "Game" text then it is a game.
