When developing or adjusting an application for offline usage, consider the following points:
- The complexity and size of the application: Create simple and small applications of a few megabytes in size and fewer sheets and objects. The Qlik Sense Mobile application runs on an iOS device with much lower CPU performance and available memory compared to a computer that uses a web browser to connect to a Qlik Sense Enterprise server. You can perform tests on an iOS device with system specifications that match those of your application consumer. Download the application, open and make selections in the data, and observe the behavior. The apps need to be small. The download is aborted if the app is not ready for download in 90 seconds when requested from the server.
- Extensions: Extensions are allowed in the Qlik Sense app. They are downloaded to the mobile device together with the applications, but they need to use local resources if the app needs to work offline. Thus, it makes sense to keep our device specifications in mind.
- Reduce the application size on download: We can create bookmarks in the app to be used by users when downloading the app. The bookmarks will reduce the data and the size of the app when it is downloaded.
To download the app with reduced data, do the following in the Mobile app hub:
- Tap on the
button under the Qlik Sense app box to open the app details window. - Tap on
. - Select a bookmark and then tap Download. The app is downloaded only with the data associated with the bookmark.
