phoneME

• 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.

Installation

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)
