How to programatically detect if an app supports Android Wear? -

im trying detect if app supports android wear or watch face.

packagemanager pm = getactivity().getpackagemanager();          list<packageinfo> packs = pm.getinstalledpackages(0);         (int = 0; < packs.size(); i++)         {} 

is code im using. feedback or suggestions awsome!

to check if android wear package exists on system:

public void foobar() {     boolean doesexist = ispackageinstalled("com.google.android.wearable.app"); }  private boolean ispackageinstalled(string packagename) {     packagemanager pm = getapplicationcontext().getpackagemanager();     try {         pm.getpackageinfo(packagename, packagemanager.get_activities);         return true;     } catch (namenotfoundexception e) {         //swallow exception         return false;     } }
