  • Page 19 For a look at such environments, review the “Motorola T720 Handset Developer Guide” which is available from the MOTOCODER website. In addition to the IDEs and Sun SDK for development, Motorola offers access to our own SDK which contains Motorola device emulators. From here, a MIDlet can be built and then deployed onto an emulated target handset.

  • Page 20: Downloading Applications

    Downloading Applications Method of Downloading The option open to the developer for deploying the MIDlet to a physical Motorola device is OTA (over -the-air) downloading. To use the OTA method, the developer will have a connection through a wireless network to a content server.

    Application Management If the user decides to save the data from the current MIDlet, the data will be preserved during the upgrade and the data will be made available for the new application. In any case, an unsigned MIDlet will not be allowed to update a signed MIDlet. Installation and Deletion Status Reports The status (success or failure) of an installation, upgrade, or deletion of a MIDlet suite will be sent to the server according to the JSR 118 specification.
