Running Java ME applications on Android

wqhl.mark

Each new software platform, including Android, at the beginning is
struggling with a small number of the available applications. This is
why Google spent $10 million trying to attract developers to their
Android Developer Challenge before G1 phone release. Taking advantage
of an opportunity to run large number of existing Java ME applications
may determine a significant value for the Android platform. This is
also occasion for developers to reduce cost preparing mobile software
for a smaller number of platforms at the same time.
MicroEmulator
,
which is pure Java implementation of Java ME API's in Java SE, seems to
be very well suited for the Android. Last few months I've been working
extending
MicroEmulator
to be
an executable environment to run Java ME applications on that platform.
Here are results of my work with demonstration of popular Java ME game
5ud0ku
automatically translated to the Android.
These are screenshots of
5ud0ku
running side by side on emulators: Java ME and Android.


Works
to complete the effort are not finished yet, but I hope a lot of
existing Java ME applications can be already transformed to Android. At
the moment code is only available in SVN repository. For anyone
interested, here is the short manual how to convert
5ud0ku
yourself:
1. Check out
MicroEmulator
from SVN repository
svn co https://microemulator.svn.sourceforge.net/svnroot/microemulator/trunk/microemulator microemulator
2. Build
MicroEmulator
project using
Maven
cd microemulator
mvn
3. Make sure that the following properties in microemu-android/build.xml correctly point to the
Android SDK
and
ASM
jar file
4. Configure properties for
5ud0ku
game, edit microemu-android/build.xml file (before you have to save 5ud0ku.jar in microemulator folder)
5. Create Android apk package with
Ant
cd microemu-android
ant
6.
And finally deploy microemu-android/bin/5ud0ku.apk on emulator or G1
phone. For all of you who don't want to go through this somehow long
procedure, here it is already prepared
5ud0ku.apk
package.
