How to Run Java Apps & Games (J2ME MIDP JAR) on Android Phone & Tablet

Hi everyone, you will find how to run Java apps (J2ME-MIDP) on Android Devices in this article. We will use Netmite App Runner, JBED, JBlend and phoneME emulator to run Java Apps on Android. All of them might not work for you – depends on your Device and ROM. But I’m sure, one of them will be absolutely working for you, so please keep reading and try these apps out.



  • phoneME for Windows CE/Mobile and Android is an implementation of the phoneME open source J2ME application platform for your Windows Mobile phone or Android handheld device.
  • Each build includes the phoneME VM and a Android frontend wrapper with JNI bindings to the VM.
  • Most powerful, smooth user experience, less crashes.
  • JAD files are also associated with the Foundation Profile-MIDP Android application. Therefore, you can also use your browser to select an online JAD file to download and run the midlet. If you click on a JAD download link, a popup menu will appear and you need to choose the Foundation Profile-MIDP Android application
  • No root access required.

These builds were made for Android 2.2 (and later). You need about 10MB of free space to store each phoneME virtual machine and Android wrapper application. You need to install the OpenIntents file manager also known as OI file manager which the Android wrapper application uses to select JAR/JAD files.

  1. Just install the apk file on your android.
  2. Install OI File Manager to select midlets (jad files) in phoneME.
  3. You need to have both jar and jad file present in the same directory in your phone.
  4. Your jar file should not contain any spaces. If it does, then remove spaces and then create the jad file using JADGen or JADMaker.
  5. Make sure there is no white space in the file path too.
    Correct => SDCARD/javagames/thefile.jad
    Incorrect => SDCARD/java games/the file.jad
Use JADGen to create jad file from a jar file. JADGen is a PC software. Download JADGen from here (password w3epic.com)
