Notes: 1:  “Context menu button” = the rectangle with horizontal lines through it, that appears on the upper-right hand corner of some screens.

2: .jad files with a MIDlet-Install-Notify line may use Internet. If you have pay-per-use data, you may want to try removing the MIDlet-Install-Notify line to avoid data usage - or just install the .jar and not the .jad

To put/install Java apps on lg xenon with  memory card follow the steps below:

1. Obtain the .jar file (and .jad file, if possible) for the application you want to load. AT&T Lg Xenon info
2. Open the .jad file (if you have one) and check the MIDlet-Jar-URL line. It should NOT have a http://web.site.address/folder/folder2/etc at the beginning. If it does, remove everything except the .jar file name. For example (this is for Google Maps), change MIDlet-Jar-URL: http://m.google.com/maps/download /b…3.2/maps_m2.jar to MIDlet-Jar-URL: maps_m2.jar
3. Copy the .jar (and .jad if you have it) file to the memory card via your PC (use a MicroSD card reader, or if you have a USB cable, connect the phone to the PC in Mass Storage mode)
4. From the Home screen, tap the Application button (box with 4 dots)
5. Tap the Folder tab
6. Tap More
7. Tap Other Files -A list of files will appear here. This seems to be a list of all the files the phone doesn’t “know” about. NOTE: You will likely see .jad and .jar files here with numbered names, like 020.jad and 020.jar, etc. DO NOT DELETE these! These are the applications that you have copied to your memory card. If you delete these, the associated application won’t work anymore and you will need to reload it.
8. Tap the .jad or .jar file you want to install. Once you go through the confirmation screens, it will be installed TO YOUR PHONE
9. If you want, go to Games or Applications and tap the Context menu button and tap Copy to or Move to if you want to move or copy the application to the memory card. Yes, I KNOW it is ALREADY on the memory card, but if you don’t do it this way, it’s not somewhere the phone knows how to access it
10. To clean up the files you used to install the app, go back to Other Files, then tap the Context menu button, tap Delete, then choose the files  to delete.
