I am the author of a General Aviation Flight Planning program called AviatorCalc. This is is written in Java Mobile Edition (J2ME)
See AviatorCalc Flight Planning for further details or Google "AviatorCalc".

A so called J2ME MIDP RUNNER from Netmite is required to support Java ME application such as AviatorCalc on Android devices. I have been able to run AviatorCalc for the most part on both an Emulator and also on an Android phone but the results were disappointing. For instance the characters displayed by the runner is are not very sharp. Also one program namely the holding pattern calculator does not display properly despite the fact that the graphics are very simple. All other programs however worked OK. These problems seem to be associated with the the Netmite MIDP runner as they don't show up on other devices such as Blackberry or Nokia. Unfortunately we able to contact Netmite for their help as their site seems to be permanently down.

I am interested if other developers have experience with the Netmite J2ME MIDP runner and what their experience was.

Any comments would be appreciated.

Hi Bob,
You can try www.UpOnTek.com for your midlet. Conversion service from J2ME to Android.

Thanks,

Microemu also looks like a candidate, especially for those of us hoping to convert a midlet where no source code is available.
MicroEmu: Converting JavaME applications to the Android platform (revisited)

I've spent some time with MIDP runner and completely struck out. I've spent a little time more recently with Microemu and didn't get stuck, but just ran out of time performing a fairly complex software installation. Microemu's advantage is that it's open source, so in principle a developer would have a better chance to figure out where the target application is failing, and have some chance of modifying the emulator to meet their needs.

Hi there,

Is it necessary to root your SGS to use these converters??

Hi All,

Their is a new Online Porting site available. It ports J2ME To Android. The cost to port J2ME is very cheap here around $10. I've tried it and it works sweet. Give it a go if you need to get your app across to Android.

You need to register first before you can port. Registration is free.

This is for anyone who is intrested.

Can you tell us anything about this Australian site? In particular: what sort of Bluetooth and/or TCP/IP support do they offer within ported applications? Do you submit JAR+JAD files? Or must you submit Java source code?

Here's a commercial group which will (automatically) convert an app for you for $10AUS. I strongly recommend this approach if your app is relatively simple, and there's only one app to convert. It didn't work for me because the app I was interested in has significant Bluetooth requirements, as well as Wifi requirements. But the resulting GUI looked fine.

Here's another commercial one, but they didn't provide a quote due to the Bluetooth/Wifi complexity that I warned them about. I guess that pricing is variable.

Here's one I haven't tried, but it looks pretty old:
Converting From J2ME | J2ME Android Bridge Space | Assembla


Here's one that I did try but didn't follow all the way through (got 80% of the way through the installation). This seems like the most powerful solution in many ways since the emulator code is all open-source, so in principle it might be possible to hunt down missing functionality and/or bugs.

Netmite looks troublesome to my eye because (I think) it's not open source and it has not been maintained in a log time. I think that a practical solution for porting should be at least one or the other.

Here is another solution if you have access to original source code

Hi i m new to Android i want to port my j2me games to Android platform .

Which of the above have you already tried? Since you apparently have multiple applications to port, MicroEmu looks like a good choice.
