Android :: Intent And URI Conversion Result

We can convert from Intent to URI and from URI to Intent. From Intent to URI string Intent intent1 = new Intent ();
String uriString = intent1.toURI ();
From URI string to Intent Uri uri = Uri.parse (uriString);
Intent intent2 = new Intent ();
intent2.setData (uri)

After conversion, intent1 and inten2 should be same. for example:
Intent intent1 = new Intent ();
intent1.addCategory (Intent.CATEGORY_HOME);
intent1.addCategory (Intent.CATEGORY_LAUNCHER);
Log.v ("", "Intent1 = " + intent1);
if (intent1.hasCategory (Intent.CATEGORY_HOME))
Log.v ("Intent1", "#1 hasCategory TRUE");
else Log.v ("Intent1", "#1 hasCategory FALSE");
String str = intent1.toURI ();
Uri uri = Uri.parse (str);
Intent intent2 = new Intent ();
intent2.setData (uri);
Log.v ("", "Intent2 = " + intent2);
if (intent2.hasCategory (Intent.CATEGORY_HOME))
Log.v ("Intent2", "#2 hasCategory TRUE");
else Log.v ("Intent2", "#2 hasCategory FALSE");
result Intent1 = { categories=android.intent.category.HOME,android.intent.category.LAUNCHER} } #1 hasCategory TRUE

Intent2 {data=#Intent;
category=android.intent.category.HOME;
category=android.intent.category.LAUNCHER;
end } #2 hasCategory FALSE

In this sample code, Intent2 is a conversion result from Intent1. If you run this sample code, Intent1 result and Intent2 result are different. Because Intent1 and Intent2 have a same Intent.CATEGORY_HOEM, the result should be Intent1 and Intent2 is TRUE (intent.hasCategory). I think this is bug. And the hint is Intent1 and Intent2 's toString result is different.
Intent1 = {categories=android.intent.category.HOME,android.intent.category.LAUNCHER}
Intent2 = { data=#Intent;category=android.intent.category.HOME
category= android.intent.category.LAUNCHER;end }

I don't know how to convert Intent to URI(String) and convert URI (String) to Intent. I want to save Intent to DB and read Intent from DB.
