LWUIT midlet does not work when converted to apk

[amit gurnani]

Hi,

I have converted an application build using LWUIT 1.4 to .apk. Used Micro-emulator for the same.

On executing the application in android emulator. Getting an error Application Stopped unexpectedly.

Below is the Log

Please let me know your inputs on this. On similar log, I had seen a comment that removing the media classes solved the issue.

I am not sure what needs to be done.

Please advise.

Thanks in Advance,

Amit

Try compiling the MIDlet itself without those LWUI classes that use "problematic" API calls not supported by microemu, such as Media Player.

Have a nice day,

Hi,

In my case, I need to remove GameCanvasImplementation.class from LWUIT jar. I dont think that will work.

And if I don't it references the 

import javax.microedition.media.Player;

import javax.microedition.media.control.VideoControl;

Do I need to remove and recompile the GameCanvasImplementation.

This is pretty urgent for me.

Thanks,

Amit
