I have observed the stack trace shared by you and following exception line doesn’t seems to be related with Aspose.Slides that is in fact cause of issue. Moreover, in your project, I have observed that you have used Aspose.Slides for Java 18.12. Can you please try using latest Aspose.Slides for Java 19.2 on your end as well.
@mudassir.fayyaz If you can see the sample code which I shared with you previously It had 19.2 that also had the same issue
If you see the stack trace you can see this
java.lang.NoClassDefFoundError: android.util.SizeF
This method aspose slides is using android.util.SizeF` method while converting ppt to pdf which is introduced in API 21 I am usiing Kitkat android 19 this is not supported there I hope it’s clear now
Thank you for the elaboration. It seems to be a missing support in Aspose.Slides for Android. An issue with ID SLIDESANDROID-154 has been created in our issue tracking system to provide the requested support. This thread has been linked with the issue so that you may be notified once the support will be available.
@mudassir.fayyaz please look into It as we want to buy and close it as soon as possible if this is resolved quickly because my team is already looking for alternatives and I’m holding them so it is difficult for me to hold them for longer as It already took approximately a month to create a Ticket so please see what can be done so that we can buy Aspose Total as it’s a priority for us to close it.
We have internally observed the requirements and this is new implementation required for KitKat 19. The issue is likely to get resolved in upcoming Aspose.Slides for Android via Java 19.4. We request for your patience till the time the issue gets resolved.
