Programmatically check mediaFileId with install4j












1














I want to programmatically check for new updates and I also want to customize the version check. Checking the version number is easy enough with the API, but how do I check the mediaFileId (like the getPossibleUpdateEntry in UpdateDescriptor does).



In a form I would simply get the current ID with context.getMediaFileId() but can I get it in my own code?

          You can save the media file ID to an installer variable, for example with a "Set a variable" action with a variable name mediaFileId and a script of



          context.getMediaFileId()


          In the set a variable action, select the property "Register for response file" property. At runtime, you can get variable value with



          com.install4j.api.launcher.Variables.getInstallerVariable("mediaFileId")


          This is indeed inconvenient, so for install4j 8 we will add a new compiler variable sys.mediaFileId that you can get at runtime like this:



          com.install4j.api.launcher.Variables.getCompilerVariable("sys.mediaFileId")


          which will also work in archives and does not require any further actions.

          com.install4j.api.launcher.Variables.getCompilerVariable("sys.mediaFileId")


          which will also work in archives and does not require any further actions.
