1. Are you providing embedded library for android?
2. Are you providing viewers for all document types?
3. Is your library able to convert all file formats to pdf?
I have observed the questions shared by you and have not been able to clearly understand the first question related to embedded library. Actually, Aspose.Slides for Android is a stand alone jar file that you use in your environment to develop the presentation files programatically. I hope this will clear the concept to you.
There is no viewer component associated with Aspose.Slides for Android as its purely an API that is capable of generating presentation files programmatically. Also, at present the rendering support is unavailable in API, therefore you may not generate slide thumbnails or export the presentation to PDF. An issue with ID SLIDESANDROID-18 has already been created in
our issue tracking system to provide support for exporting presentation
files to PDF. This thread has been linked with the issue so that you may
be automatically notified once the issue will be fixed.
The issues you have found earlier (filed as SLIDESANDROID-18) have been fixed in this update.
