How to convert j2me project into android with j2me source code

[tim]

dear all,

I have problems after converting the jar into apk successfully, when I
run the apk, it always alerts "stopped unexpectedly"
So I am wondering if I can compile the project with my own j2me source
code.
Or anyone can help me find out why my apk always fails?

thanks

Hi,

You are trying to use JSR-135 (Multimedia API) which is not a part of
open source MicroEmulator project (access to the PlayerListener
class). For the comercial version that includes the JSR-135
implementation, please contact the email in...@microemu.com

Hi,

It seems your application uses JSR-120 (WMA) which is not available by
the open source part of the project. MicroEmu (www.microemu.com)
provides several commercial Android JSR's implementations that
includes the JSR-120.

BR,
Bartek Teodorczyk

i think the problem is here

V/MicroEmulator( 221): error Message: Error: Unable to find MIDlet
class, java.lang.ClassNotFoundException: mobile.wallet.FinnetMC in
loader dalvik.syste
m.PathClassLoader@43d0b5c8 java.lang.ClassNotFoundException:
mobile.wallet.FinnetMC in loader
dalvik.system.PathClassLoader@43d0b5c8
V/MicroEmulator( 221):
V/MicroEmulator( 221): java.lang.ClassNotFoundException:
mobile.wallet.FinnetMC in loader
dalvik.system.PathClassLoader@43d0b5c8

this isn't about JSR but where i have to set the android path ?

Hi,

The real problem is in missing MessageListener class which is part of JSR-120.

V/MicroEmulator( 221):

417 'Ljavax/wireless/messaging/MessageListener;'
