Thanks for your interest in Aspose.Slides.
I have separated your thread post to a new thread so that we may handle the request separately.
I have observed the requirements shared by you and regret to share that at present the rendering support is unavailable in Aspose.Slides for Android. An issue with ID SLIDESANDROID-15 has already been created in our issue tracking system to provide the presentation to HTML support. A separate issue with ID SLIDESANDROID-19 has been added to provide support for generating the presentation slide images. This thread has been linked with the issues so that you may be automatically notified once the support will be available.
We are sorry for your inconvenience,
The issues you have found earlier (filed as SLIDESANDROID-15,SLIDESANDROID-19) have been fixed in this update.
