Android :: How To Check If Flash Installed

I'm using this snippet to check if an app/activity is installed:

public static boolean isIntentAvailable(Context context, String action) {
final PackageManager packageManager = context.getPackageManager();
final Intent intent = new Intent(action);
List<ResolveInfo> list =
packageManager.queryIntentActivities(intent,
PackageManager.MATCH_DEFAULT_ONLY);
return list.size() > 0;
} public static boolean isScanAvailable(Context context) {
return isIntentAvailable(context, "com.google.zxing.client.android.SCAN");
}

In the above example it checks if the Barcode Scanner App is installed, which works just fine. However, if I try to check for the Adobe Flashplayer using com.adobe.flashplayer it doesn't work and always returns false. Is there a better / more reliable method to check for Flash?
