To fix this, ensure all your source files are saved in before compilation, and check the MRE SDK project settings for proper language configuration.
VXP games are hardcoded to specific screen dimensions (usually 240x320 or 128x160). Always match the file version to your physical phone screen size for the best experience. Share public link
To actually convert a Java application (.jar) to an MRE application (.vxp), you generally need the and a compiler.
: Java ME applications are written in Java, while MRE applications are written in C or C++. A direct "conversion" would require translating code from one language to another, a task far beyond a simple file conversion tool. convert jar to vxp link
Choose the output folder and select as the conversion option.
For example, in Eclipse, you can use the plugin to convert JAR files to VXP format.
However, this does not mean your project is a lost cause. This guide will provide you with the necessary background information and show you the viable paths forward. We will explore the real-world possibilities for bringing your JAR applications to the VXP platform.
A VXP file is basically:

Converting a JAR file to a VXP format is primarily done to allow Java-based apps or games to run on older feature phones (often called "dumbphones") that use the MRE (Maui Runtime Environment) platform . How to Convert JAR to VXP The standard format for Java ME (Micro Edition)
Download the MediaTek MRE SDK (often requires an older operating system like Windows XP or Windows 7 for compatibility).
The process is surprisingly straightforward. You upload your JAR, wait for the cloud-based gears to turn, and download the resulting VXP.
Your phone might have MRE disabled by the manufacturer. Try dialing *#220807# on your keypad. If the phone tries to open a browser or access a memory folder, MRE is active.
