Otherwise, is it possible to convert .jad files to .apk? In this case,

Answer 1

You can try phoneME, netmite j2me app runner, jblend, jbed like jeme emulators in android. For now, phoneME is the best. you can get various version of phoneME here http://davy.preuveneers.be/phoneme You also need OI file manager to select files in phoneME.

A complete guide can be found here http://w3epic.com/run-java-apps-j2me-on-android-devices-guide/ for rest of other emulators (if you want to try).

@dennis I got it, thanks.

Answer 2

Using this site http://www.netmite.com/android/srv/2.0/getapk.php you can convert your J2ME application in to Android Application. You need to just supply your .Jad & .Jar file in it and it will generate Android's executable file .apk for you.

However in it doesn't able to convert all the feature of Java ME to Android, but basics can be easily converted.

Hi,

I am testing on a Samsung Galaxy S4 running Android 5.0.1, and the "phoneME Advanced - Foundation Profile + MIDP FullHD Resolution" build seems to run just fine on this device.

Also, following this thread Position Independent Executables and Android Lollipop, I ran:

$ readelf -l libcvm.so | grep -i "file type"

and it reports:

Elf file type is DYN (Shared object file)

So according to the website this is OK.

However, for the CDC and Foundation profiles (console like applications), there is indeed an issue where you get this error:

"Error: only position independent executables (PIE) are supported"

However, for those 2 profile I call a native executables and redirect the native stdout/stderr streams to Android, whereas for the MIDP dual stack I load a library and create a complicated wrapper to get things going.

I can recompile with -fPIE and -pie options but will then end up with binaries that are no longer backwards compatible with devices running Android 4.0 and below. That is why I added some additional builds to my website for Android 5+ devices:
