[android] how can I know if there is any application which can handle an intent.

android,   how can I know if there is any application which can handle an intent?

public static boolean hasAvailableIntentHandlingApp( Context context, Intent intent ){

List<ResolveInfo> list = context.getPackageManager().queryIntentActivities( intent, PackageManager.MATCH_DEFAULT_ONLY );

return list.size() != 0;

}

Android, hasAvailableIntentHandlingApp, match_default_only, PackageManager, queryintentactivity, resolveinfo, 안드로이드
