Very slow when scroll down list / Page on android device

[Former Member]

Hi experts,

I have a question about performance of sapui5 on android device.

The device is a phone with barcode scanner.

Android Version: 4.0.4

My application is a cordova project with sapui5.

It contains a list to view data. The application become very very slow when I scroll down the list / page.

What can I do to improve this situation?

Please help.

Thank you

Hi Man Kit,

What's the size of items on the list? If it's big, you could set growing to true on the list. From the API Reference:

For mobile devices, the recommended limit of list items is 100 to assure proper performance. To improve initial rendering of large lists, use the "growing" feature

May be that there is some other code that is causing the application to slow down. Can you test your application on desktop browser or is it Cordova only? Of course, on desktop you cannot debug device features if those are the sources for the performance problem. Also, I would recommend Remote Debugging on Android but Cordova Webview requires Android 4.4+.
