I started of in mobile in J2ME and am not looking back, you would want a sizeable portion of the market to even consider switching from the Android/iOS SDKs unless you also have a passion for self harm. Even something as simple as signing and certification is a massive headache as theres no standardisation of what root certificates are in devices. The UTi and Java Verfied (Java Verfried as we called it) came very close but its still not 100% No one really upgraded the firmware in their devices and the Java machine could not be updated, when fragmentation issues were solved, it was painful but some useful lessons were learned I guess!

In my (limited) experience, it's fairly difficult to find J2ME devices which are easy to get code on- most cheap feature phones use proprietary cables and software for data transfer. If anybody can prove me wrong, please do. As a hobbyist, a dirt-cheap commodity Java platform would neat to have.

  It's fairly easy: run a webserver and upload the jad/jar to it. Host a page linking to the jad. Visit page from phone, and select that link. The downside is you pay for the data on your cell plan. Alternatively blasting the jar at the device over bluetooth is also likely to work.

    I had an older nokia phone that i could do that with over bluetooth, but it would usually fail to recognize the certificates unless put on to it by the nokia software rather than standard obex.

  Most of cheap nokias are fairly easy to do so, they come with a common micro usb port and that is all.

  If you want my advice get an old JP8 Sony, so something like the K850, fast Java machine that only has some issues with optional apis and you can provision just the JAR via its USB cable or Bluetooth really easily. If you do get something running you can be semi confident it runs on the other JP8s
