LWUIT running on Android

This time I'd like to show how advanced Java ME applications can be easily converted to the Android. As an example I took LWUIT Demo and below here it is video that I captured from the emulator. For conversion I followed almost the same process as it was previously described in Running Java ME applications on Android article.

Similar work has already been done for iPhone, but only for that jailbroken ones. More information is available here.

Where can I download the lwuit demo

Can you please add link to apk file that we can test it

pakmee said...

u can use the apk converter.

Vikrant Bains said...

To get Apk
step1:- get jad and jar for LWUITDemo
Go to -->https://lwuit.dev.java.net/servlets/ProjectProcess?tab=1

step2:- To convert the MIDlet's into apk, go to --
http://netmite.com/android/srv/1.6/getapk.php

and choose second option and then save the generated apk file.

Hope that helps..I just did it..
For more stuff go to
sites.google.com/site/vikantbains

enjoy Droid :)

Vikrant Bains, netmite is a different product which offers easy conversion tool but it is not free if you want to distribute your converted application. MicroEmulator is also an open source project.

TiGeR said...

btw I see you judiciously have skipped the transitions part of the demo ? It's too slow for that I guess ? I am used to using LWUIT for developing MIDlets and if I look at the animations it's all running very slow...

Bartek said...

TiGeR,

LWUIT transitions are implemented using JSR-184. This JSR is only available as commercial extension for MicroEmulator. Contact me via email (microemu at gmail.com) if you are interested in licensing.

TiGeR said...

sorry Bartek not in this moment of time, we might be going to develop for Android in the near future but there are no real plans for that... I was just mentioning what I noticed :D

Hi,

I try to run javame LWUIT application on Android emulator but it's failed.

- Helloworld application with LCDUI Form runs without problem
- Helloworld application with LWUIT Form doesn't run
- LWUIT-Demo doesn't run too
The error is the following: "The application UIDemoMIDlet (process org.microemu.android.com.sun.lwuit.uidemo.UIDemoMIDlet) has stopped unexpectedly. Please try again."

LWUIT-Demo is compiled with Netbeans and runs on emulator devices.
LWUIT-Demo.apk is generated with micoremu-android ant script, and install with "adb install LWUIT-Demo.apk".

Please, could you help me please.
Thank you very much

juien_m,

What does logcat say? Any exception thrown?

juien_m said...

Bartek,

Where can I found log file?

I've just the following error when I want to run the application on Android Emulator:

"The application UIDemoMIDlet (process org.microemu.android.com.sun.lwuit.uidemo.UIDemoMIDlet) has stopped unexpectedly. Please try again."

Bartek Teodorczyk said...

juien_m,

You need Eclipse SDK with Android plugin:
http://developer.android.com/sdk/eclipse-adt.html

or, use adb tool from Android SDK:
http://developer.android.com/guide/developing/tools/adb.html

juien_m said...

Bartek,

I already use adb tool.

hayktsirunyan said...

I'm also getting the same error. In my opinion can not convert LWUIT to APK !!!!
Or if possible tell me how convert LWUIT ???? ! commercial non-profit ... DOES NOT WORK!

hayktsirunyan said...

I use ADB ANDROID app for Windows , ADB INSTALL MYAPP.APK !. Always the same exception
I remove all 3D transision...all remove ..no show FORM !

hayktsirunyan,

I think there should be also some important information in logs before the fragment that you attached.

Hi Bartek, I could get LWUITDemo apk and it runs on android emulator, but when I change the orientation (ctrl + F11), app crash :S. Logcat says first time I rotate:

--------------
...and screen goes black...then I rotate again and logcat says:

be valid in case of a resize in the middle of a transition

I have a midlet with lwuit and have the same problem with that. Any advice I would appreciate. Thanks!

NaveganteSilencioso,

It is hard to say anything about the error when your application is obfuscated and all the classes and methods got cryptic names. Are you able to test the unobfuscated build?

NaveganteSilencioso,

It looks like a bug in the LWUIT library.

Laura said...

Hi, I try to run a Lwuit application but I'm getting this message: "The application amovil (process org.microemu.android.Interfaz.Amovil) has stopped unexpectedly. Please try again. Force close."
This is the log:
https://docs.google.com/document/d/10O1m0uriA-ddcaALWWwSl_VVcxqdnvyPrXcEeJPjOEw/edit
So, I removed javax.microedition.media.Player and javax.microedition.media.control.VideoControl from com.sun.lwuit.impl.midp.GameCanvasImplementation, but when I try to run the application again it shows a black screen and this is the log:
https://docs.google.com/document/d/1kfYsyuvQEq3Il9HwpEaJwW1JkDNEddvOd7-4DYvUDw8/edit
I would really appreciate if you help me.
Regards, Laura.

Laura,

Did you manage to solve already your problem?

Hi...I have developed application using LWUIT 1.4.
I have converted it using Microemulator.
But on running the application in the emulator I am getting the error "The application has stopped unexpectedly"

It is a problem with the media classes I suppose.

Can you please guide me. It is very urgent.

Thanks in Advance,
