Andorid Client Crash MDK

[c_chowdary]

Hi,

I am currently developing an MDK App in 6.3 version using Object Card Collection control and build a custom client with MDK SDK 6.3.0.Unfortunately, Android app is getting crashed when I try to redraw the page with Object Card Control. Its working fine in IOS. I am using Android 9 and tested the same in Android 10.

How do I resolve this error?

I am using this page on click of button from main page.

Page Definition:

Are you using Object Card collection control on the main page? Can you share page definition where you are using this crash?

[bill_froelich · Accepted solution]

MDK 6.3.1 has been released. Please download from the SAP Marketplace and test to confirm it addresses this issue.

[c_chowdary · Accepted solution]

Yes, Crash issue is resolved but Object card collection doesn't show empty section caption when there is no data in Android.

[bill_froelich · Accepted solution]

I opened an internal bug for the empty section issue on Android

[bill_froelich]

I setup a test app and was able to see a crash just loading your page with MDK 6.3.0. Using an internal build for 6.3.1 everything appears to be working as expected. Based on that I am hopeful the patch will also address the issue for your specific app as well.

[bill_froelich]

We are aware of some issues with the Object Card collection that we are addressing in the upcoming MDK 6.3.1 patch. How are you triggering the redraw? I want to see if your scenario will be addressed with the upcoming patch fixes or if this is a new scenario we need to investigate.

Thanks for the quick response.

I am just redrawing the sectioned table of the page in a rule (onPulldown) by evaluating target path.
