It could be the case that your phone just doesn't have the memory to store a whole video clip.

It may also be the case that the phone doesn't support JSR 135: Mobile Media API -- it's an optional package that may not be included in all cell phones.

Java ME MIDP 2.0 is deceiving in that javax.microedition.media.* looks exactly like JSR 135, but, without JSR 135, MIDP 2 just supports a smaller subset of the Mobile Media API that only provides audio playback, no video -- Mobile Media API Overview.

Media in MIDP 2.0

The MIDP 2.0 specification includes a subset of the Mobile Media API. It is upwardly compatible with the full API. The MIDP 2.0 subset has the following characteristics:

  • Only audio playback (and possibly recording) is supported. No video-specific control interfaces are included.
  • Multiple players cannot be synchronized.
  • The DataSource class and the rest of the javax.microedition.media.protocol package are excluded; applications cannot provide their own protocol implementations.
  • The Manager class is simplified.

  • MIDP 2.0 requires support for tone generation and sampled .wav audio playback.


    When you create a project in Java ME SDK it will, by default, enable all the optional packages. Go to your "Projects" pane, right-click your project, and choose "properties" to see which ones are "on."

    On the Category: "Platform" screen, under "Optional packages," all the checked packages will appear to function on the emulator but won't work on a cell phone if it doesn't include those packages, Optional being the keyword.
