A VXP file is basically:
This is the most labor-intensive part. There is no automation here. You will have to:
Find a blank VXP shell that contains the J2ME Loader engine. (Look on XDA Developers or the KaiOS Store archives for "J2ME Loader VXP"). convert jar to vxp link
The only true way to get a Java-like app into VXP format is to have the original source code and recompile it using the MediaTek MRE SDK
A binary executable (specifically an ARM ELF object) designed for MediaTek-based feature phones. It is written in C or C++, not Java. Can You Convert JAR to VXP? A VXP file is basically: This is the
What is the exact of the phone you are using?
Open the MRE SDK and create a new project. Select the screen resolution that matches your target feature phone (typically 240x320 or 320x480). 3. Integrate the Java Emulator Code (Look on XDA Developers or the KaiOS Store
A common challenge is trying to run Java-based mobile applications on budget feature phones powered by MediaTek processors. This guide explains how to convert files to VXP (MediaTek MRE) format, the limitations of this process, and how to find working conversion links. Understanding the Formats: JAR vs. VXP
