Think of VXP as a locked-down cousin of the Android APK. It contains native code ( armv7 or armv8 ) compiled specifically for the phone’s processor, plus assets like images and sounds.
Use the SDK compiler to build the project directly into a .vxp binary. convert jar to vxp link
Because VXP phones are highly heterogeneous (different screen sizes, keymaps, heap limits), a JAR that works on one VXP device may crash on another.
: VXP is strictly for MediaTek-based phones. If your device uses an Unisoc chipset (like some newer Nokia 105 4G models), it will not support VXP files regardless of conversion. [ARM code header] + [resources] + [executable] Think
Unzip your JAR file using a tool like 7-Zip to extract the images, audio, and resource files.

Download J2ME Loader from the Google Play Store. It runs almost any JAR file flawlessly with customizable touch controls.
Converting JAR (Java Archive) files to the VXP (Matrix MRE) format allows you to run classic mobile games and applications on budget feature phones. Many modern-day button phones, especially those powered by MediaTek chips, utilize the VXP format instead of the older Java standard.
