Found this interesting thread:

If it is possible for Qt, it is possible for us as well Smile

Interesting. If U++ gets supported on Android, I might start thinking about buying a new phone Smile

BTW: The videos looked like there is some kind of emulator - that should make the porting much easier...

Android has capabilities that surprised me.

U++ should work OK.

imagine developing U++ projects on Android, for remote controling SQL and all the stuff... doing native C++ is preferable to java sometimes Smile

thats even more interesting that porting to Apple Mac

If U++ can access the GPS through a virtual com port as well that would be fantastic! Has there been any progress on this? Is there likely to be a release of U++ for Android?

I've wanted to port my app to Android for a while but I wouldn't really know where to start. Java is not worth looking at for what I do as it is way too slow for a GIS style app.

That depends. Mirek, are you planning on buying a Nexus One anytime soon? Smile

To the beginning of the tests, can use the Android Emulator.

Android Emulator

Oh, you see the name, "deal extreme" Twisted Evil

A friend of mine told me about this address. The delivery lasted three weeks but he received the items, and they worked Razz .

Coming to the porting, our disadvantage is that Nokia (Qt) is interested in mobile cross-platform developing.

However, our advantage is that porting Qt is much more difficult than porting U++.

thats true,

nevertheless, i i'am lucky, i might finish porting U++ to framebuffer till the end of the month.. this should also work for android then, which uses framebuffer as underlyinig layer. but this would be a intermediate solution only. since android brings in own window manager which we should be using to make upp applications run just as the normal ones.

BTW, possible interesting approach might be the "reversed library" (just made up the term).

Android certainly supports C libraries in Java. So make the U++ app as library and give it some Java encapsulation outer shell Smile

Did some browsing:

http://java.sun.com/docs/books/jni/html/fldmeth.html#11202

Looks like calling java back from native code should be possible.

Given this fact, I wonder why is there so much fuss about Android not supporting native development. IMO, solution is simple - create Java interface class to Java SDK and pass a pointer to its instance to C++ code doing the actual stuff.. Smile

Hello all

Now the main mobile platforms are RIM (Blackberry), Android, Iphone, Meego (Maemo-Nokia+Moblin-Intel) and Windows Mobile/Phone.

The tools to develop in some of those platforms are:
- Android: Java, and partly C++(NDK)
- Meego: Qt C++, loosing support to Gtk+
- Windows Mobile: From version 7, only C#-Silverlight

So the siuation is terrible for all...

I have seen some moves in forums:

- Qt is being slowly ported to Iphone and Android. No problem with MeeGo. No idea about mobile 7.
- WxWidgets is being ported to Qt-Maemo Shocked . They think Maemo will leave Gtk+. No Android and mobile 7 move.
- CEGCC, the developers of a development environment for Windows CE/Mobile platforms are very upset about mobile 7. They are thinking to quit Sad

In summary, balancing technical issues and market forecasts, I would propose to invest our mobile devices time and efforts in Android.
