With this the application looked something like this:įinally some results! There are some issues at the tile borders but this will be eventually resolved. The application uses OpenGL ES 2 for rendering so the user experience is smooth for the most parts (there are still things to optimize). By using a mock document tiles (tiles of the document that are part of the application's assets) I was able to make the application work without actually interfacing with LibreOffice yet.

The calls to Gecko (rendering engine in Firefox) were replaced with our own implementation either in Java or a facade to LibreOfficeKit. Fennec already solves many of the problems that we would need to solve - especially concerning drawing of tiles, touch handling, scrolling, tools and removed the rest, that will not be needed or needed later in development. The first goal is to prepare the base of the application so I used the Fennec (Firefox for Android) source code. In the last couple of weeks I have been working on making this plan a reality. The application itself should be a Android native application and use LibreOffice (interfacing through LibreOfficeKit) to provide tiles of a rendered documents and other needed pieces.

Afterwards build on that and provide more features and eventually editing. Thanks to Smoose, we are now able to do some real progress with the Android version of LibreOffice. The idea is to first build a LibreOffice document viewer, which is able to display any type of document that is supported by LibreOffice.
