PC-based software installation

SIS files can be installed in two ways.

The file can either exist on the phone, in which case the software installation engine will just read the file, or it can be installed directly from a PC connected to the phone.

The process for PC-based installation from v9.x onwards is:-

• the PC-based installation software identifies a connected phone,

• a connection is made to the software installation engine on the phone,

• the install file (for instance JAR, JAD or SIS) is copied to the phone before installation begins,

• installation is then handled entirely by the phone's UI. The PC-based installation software has no further involvement in the installation.

Prior to v9.x, several callbacks were made during installation by the software install engine, which were handled on the PC to provide information to the user and to get user input via various dialogs, for instance progress notification, language and drive selection, licence agreements, query and error dialogs.

From v9.x onwards, these callbacks no longer occur. All the installation dialogs are displayed on the phone. An initial event is generated and handled on the PC side to notify the user that the install file has been transferred to the phone and that the installation is about to commence. From that point onwards, no more installation events are sent to the PC, until it receives a final event indicating whether the installation was successful or not.
