Can You Install Java on a Cell Phone?


Java for mobile phones has been a recent development. Sun Microsystems, the creators of the Java Runtime Environment, released Java ME in April 2009 to run new mobile phone applications, and technologies that allow for greater website display and even games. It is now possible to use Java on almost every smart phone and PDA with smaller running environments available for lower powered devices as well.

Enable Web Browsing

  • Begin by enabling web browsing on your mobile phone. In order to download any software to a mobile phone, it must be able to browse the web and download applications. You thus need a so-called data plan for the phone, as the cost of receiving and sending data without one can accumulate quickly, raising costs dramatically. Visit the website of Sun Microsystems (the creators of Java) at This will bring the browser to a download page where the user may select a mobile Java application for download.

Java ME

  • Download Java’s Micro Edition (called Java ME) Configuration for small devices (called the CLDC). The limited device configuration will allow the mobile phone to run Java applications on a small scale, working with the limited memory capacity of the mobile phone and processor power to run graphic capabilities. Click the “download” button next to the Connected Limited Device Configuration 1.1 to begin the download to the mobile phone. This particular service is not for more capable devices like smart phones and PDAs.

Connected Device Configuration

  • Users who possess these devices should download the Connected Device Configuration (or CDC) that will enable a complete Java Runtime Environment for the smart phone or high-end PDA. Click the “download” icon next to the Connected Device Configuration 1.0.2. This platform will enable a user’s phone to process and run “MIDIlets” which are active running Java programs written once and sent to multiple users. iPhone applications are perfect examples of these programs and unless Java is properly installed on the mobile phone, they won’t run.
