!JavaRosa General Device Support
Memory Requirements
!JavaRosa requires a reasonably large heap size in its current incarnation to be able to run. In order to run !JavaRosa, around 500,000 bytes of memory should be available. To load forms and be fully functional, somewhere around 850,000 bytes of memory is required. To identify the total memory available to phone JVM's, try [http://jbenchmark.com/index.jsp jbenchmark's] numbers. The operative field is "Total Memory" under "JVM general". In our experience, phones with 600KB total JVM heap (such as the Nokia 2600c and 2630) '''cannot''' run JavaRosa reliably, even for small forms. Phones with 2MB of heap (such as the Nokia 3110c and 6085) can run JavaRosa comfortably, even for large forms.
In order to test whether a device's memory footprint is sufficient for your particular !JavaRosa application, add the parameter "-Xheapsize" with the appropriate value in bytes to the emulator task in the build.xml file, as in the following example. An example should also exist in the current build.xml file.
<emulator wait="true" securityDomain="trusted" enableProfiler="true" enableMemoryMonitor="true" enableNetworkMonitor="false" if="debug"> <parameter name="-Xheapsize" value="850000"/> </emulator>
Samsung Considered Harmful
From http://forum2.mobile-review.com/archive/index.php/t-40430.html :
"It is NOT officially possible to install java MIDlets on samsung handsets (excluding smartphones) via bluetooth, IrDa, USB cable or serial cable. MIDlets can only be downloaded by Over-The-Air (OTA) via a download server."
There does exist a hacky way to do it on some models, but it requires installation of 2 or 3 programs and I think only works on Windows. So for those of us with slow or no GPRS, or without unlimited data plans, Samsung looks thus like a bad idea. Also, the interface on the phone I tried, the e200, is somewhat annoying.
UPDATE: Even more reason to stay away:

"Their Java efforts have always been decidedly middling though - many many bugs, documented on the old forums before they were deleted, and very few APIs beyond the basic MIDP and CLDC. Their LCDUI implementations are usually straight out of the WTK, offering no native UI functions and feeling completely alien to the phones."
