Class Detail

Storage#upgradeApplication(successCallback, errorCallback, options)

Upgrades application stored in local or USB using the one from remote server. Remote server information(serverIP and serverPort) is set in display menu.
New application will be launched at next boot time and old application will be deleted at the same time. Application on the server should be at
"http://serverIP:serverPort/procentric/scap/application/scap_app.zip".
Note : Size of scap_app.zip (zip file itself and extracted files) should not exceed free storage size of the platform.
When application is being upgraded, following files exist at the same time :
- old application
- downloaded scap_app.zip
- content data stored by storage.copyFile() API and
- new application extracted from the downloaded scap_app.zip
So before upgrading the application, call storage.getStorageInfo() and check the free storage size.

Note : Application should not include 'content' directory under application's root folder.
(It is reserved for Storage.copyFile() API.)
