Android Viewer does not switch edit mode to view: ĩ. Android Viewer does not show page count: ħ. Android Viewer doesn't focus on the word you search: Ħ. Fix typo: 'forgeround' in multiple files: ĥ. Top part unreachable with soft keyboard open: ģ. *Full list of bugs solved and other patches*ġ. Ability to insert pictures from taking photos, choosing local images, downloading cloud images (Google photos, Dropbox, etc.) with an option to compress the image or not: Ability for user to double tap to zoom in and out: ĩ. Developer Mode for sending UNO commands in the app without debugging tool: Ĩ. Presentation Mode in slideshow documents: ħ. Address and formula bars in spreadsheet UI: Ħ. insert/delete/hide/show/optimal width or height in spreadsheet UI: ĥ. Interactive spreadsheet UI with row/column headers: Ĥ. Auto-updated page number information in text documents: ģ. Ability to load password-protected documents: Ģ. I had to learn by mimicking other parts of the code, which worked well.ġ. This task was pretty challenging since I never did C++ programming before.

And of course password related JNI functions came afterwards. So, I implemented the messageRetrieved and the bindMessageCallback and so on, for LO Office instance as Android JNI. However, in order to provide password, we need to implement the LO Office instance which takes the password. I tried to implement this functionality and found out that in Android Viewer actually only the LO Document instance is implemented.

Ability to load password-protected documentsĪndroid Viewer was not able to load password protected documents because the proper JNI functions didn't exist. Luckily, now they work pretty nicely.Īfter the selection worked, I went on and implemented address bar and formula bar, which was quite simple.įinally, I implemented insert/delete/hide/show/adjust width/height, which were straightforward but required a lot of care and caution.ģ. The selection involves emitting calls to LOKit and listening to callbacks from LOKit. They are implemented differently, since cells are on the main GL view and rows/columns are supposed to relate to the top and left header views. Someone who knows LO very well should tackle this issue.Īfter the headers started to work, I implemented selecting cells and rows/columns. So, we decided to fix the zoom to 1x and DPI to 96 to work around. The zooming is problematic just like in LOOL, in which the retrieved header info doesn't match what's showing on the main GL view. The tricky part involves calculating the size of the headers in pixels and also adapt them when the user pans and zooms. The result turned out to be quite neat and quick. Basically, whenever there is a refresh on the headers, we draw the headers on the left and top views one by one. The drawing of headers is achieved by CanvasElement. I decided to add 2 independent Views left and top and only show them when user opens Calc files.

The challenge here is how to add headers to Calc UI. Header info can be retrieved with a LOKit call and the JNI functions are already implemented before I started. Then the user can go to Chrome or Firefox and load the file manually. So, I did an alert dialog for pre-KitKat Android phones and copy the link to system clipboard. Pre-KitKat Android doesn't have this support because the default WebView engine is not chrome yet. The SVG support of WebView is strongly related to Android version of the running device. I export the presentation as a SVG file and then show it in a WebView.

The version control tool I used is git and code review through Gerrit. The programming language is primarily Java, some XML, and some C++. Then main tool I used is Android Studio, the official IDE from Google for developing Android apps. My work during this project is focused on adding new features to LibreOffice Android Viewer and solving most annoying bugs for it. LibreOffice works nicely on Android these days, but there are still many things to improve and fix. LibreOffice is a modern Free & Open Source Office suite, one of the largest open source projects, and used by millions of users worldwide.
