In +addition it is a home to `LibreOfficeKit` (LOK - see `libreofficekit/README.md`) JNI +classes. + +## Stuff in Source Directory + +LibreOffice Android application - the code is based on Fennec (Firefox for Android). +It uses OpenGL ES 2 for rendering of the document tiles which are gathered from +LibreOffice using LOK. The application contains the LibreOffice core in one shared +library: `liblo-native-code.so`, which is bundled together with the application. + +## Architecture and Threading + +The application implements editing support using 4 threads: + +1. The Android UI thread, we can't perform anything here that would take a considerable + amount of time. +2. An OpenGL thread which contains the OpenGL context and is responsible for drawing + all layers (including tiles) to the screen. +3. A thread (`LOKitThread`), that performs `LibreOfficeKit` calls, which may take more time + to complete. In addition it also receives events from the soffice thread (see below) + when the callback emits an event. Events are stored in a blocking queue (thread + processes events in FCFS order, goes to sleep when no more event is available and + awakens when there are events in the queue again). +4. A native thread created by LibreOfficeKit (we call it the soffice thread), where + LibreOffice itself runs. It receives calls from `LOKitThread`, and may emit callback + events as necessary. + +## LOKitThread + +`LOKitThread` (`org.libreoffice.LOKitThread`) communicates with LO via JNI (this can +be done only for one thread) and processes events (defined in `org.libreoffice.LOEvent`) +triggered from UI. + +## Application Overview + +LibreOfficeMainActivity (`org.libreoffice.LibreOfficeMainActivity`) is the entry point +of the application - everything starts up and tears down from here (`onCreate`, `onResume`, +`onPause`, `onStart`, `onStop`, `onDestroy`). + +### Document View + +From here on one of the most interesting pieces are the classes around document view, +which includes listening to touch events, recalculating the viewport, tiled handling +and rendering the layers to the document. + +`Viewport` - the viewport is the currently visible part of the document. It is defined + by view rectangle and zoom. + +`Layers` - document view is rendered using many layers. Such layers are: document + background, scroll handles, and also the document tiles. + +### Document View Classes + +- `LayerView` (`org.mozilla.gecko.gfx.LayerView`) is the document view of the application. + It uses the `SurfaceView` (`android.view.SurfaceView`) as the main surface to draw on + using OpenGL ES 2. + +- `GLController` (`org.mozilla.gecko.gfx.GLController`) - holder of the OpenGL context. + +- `RenderControllerThread` (`org.mozilla.gecko.gfx.RenderControllerThread`) executes the + rendering requests through LayerRenderer. + +- `LayerRenderer` (`org.mozilla.gecko.gfx.LayerRenderer`) renders all the layers. + +- `GeckoLayerClient` (`org.mozilla.gecko.gfx.GeckoLayerClient`) is the middle man of the + application, which connects all the bits together. It is the document view layer + holder so the any management (including tiled rendering) usually go through this + class. It listens to draw requests and viewport changes from `PanZoomController` + (see "Touch events"). + +### Touch Events, Scrolling and Zooming + +The main class that handles the touch event, scrolling and zooming is `JavaPanZoomController` +`org.mozilla.gecko.gfx.JavaPanZoomController` (implementation of `PanZoomController` interface). +When the user performs a touch action, the document view needs to change, which means the +viewport changes. `JavaPanZoomController` changes the viewport and signals the change through +`PanZoomTarget` (`org.mozilla.gecko.gfx.PanZoomTarget`). + +### Tiled Rendering + +Tiled rendering is a technique that splits the document to bitmaps of same size (typically +256x256) which are fetched on demand. + +In the application the `ComposedTileLayer` (`org.mozilla.gecko.gfx.ComposedTileLayer`) is the +layer responsible for tracking and managing the tiles. Tiles are in this case also layers +(sub layers?) implemented in `SubTile` (`org.mozilla.gecko.gfx.SubTile`), where each one is +responsible for one tile bitmap (actually OpenGL texture once it has been uploaded). + +When the viewport changes, the request for tile rechecking is send to `LOKitThread` (see +LOKitThread#tileReevaluationRequest), where the tiles are rechecked, add and removed if +necessary. + +`CompositeTileLayer` is actually an abstract class, which has two implementations. One is +`DynamicTileLayer` (`org.mozilla.gecko.gfx.DynamicTileLayer`), which is used for main tile +view of the document, and `FixedZoomTileLayer` (`org.mozilla.gecko.gfx.FixedZoomTileLayer`), +which just renders the tiles at a fixed zoom level. This is then used as a background +low resolution layer. + +### Tile Invalidation + +Tile can change in LibreOffice when user changes the content (adds, removes text or changes +the properties). In this case, an invalidation rectangle is signaled from LibreOffice, which +includes a rectangle that needs to be invalidated. In this case `LOKitThread` gets this request +via callback, and rechecks all tiles if they need to be invalidated. For more details see +LOKitThread#tileInvalidation). + +## Editing + +For editing there are 2 coarse tasks that the LibreOffice app must do: + +1. send input events to LibreOffice core (keyboard, touch and mouse) +2. listen to messages (provided via callback) from LibreOffice core and react accordingly + +In most cases when an input event happens and is send to the LO core, then a message from +LO core follows. For example: when the user writes to the keyboard, key event is sent and +an invalidation request from LO core follows. When user touches an image, a mouse event is +sent, and a "new graphic selection" message from LO core follows. + +All keyboard and touch events are sent to `LOKitThread` as `LOEvents`. In `LOKitThread` they are +processed and sent to LibreOffice core. The touch events originate in `JavaPanZoomController`, +the keyboard events in `LOKitInputConnectionHandler` (`org.libreoffice.LOKitInputConnectionHandler`), +however there are other parts too - depending on the need. + +`InvalidationHandler` (`org.libreoffice.InvalidationHandler`) is the class that is responsible +to process messages from LibreOffice core and to track the state. + +## Overlay + +Overlay elements like cursor and selections aren't drawn by the LO core, instead the core +only provides data (cursor position, selection rectangles) and the app needs to draw them. +`DocumentOverlay` (`org.libreoffice.overlay.DocumentOverlay`) and `DocumentOverlayView` +(`org.libreoffice.overlay.DocumentOverlayView`) are the classes that provide the overlay over +the document, where selections and the cursor is drawn. + + +## Icons + +App uses material design icons available at [1]. + + +[1] - <https://www.google.com/design/icons/> + +## Emulator and Debugging Notes + +For instructions on how to build for Android, see `README.cross`. + +### Getting Something Running + +Attach your device, so 'adb devices' shows it. Then run: + + cd android/source + make install + adb logcat + +and if all goes well, you should have some nice debug output to enjoy when you +start the app. + +### Using the Emulator + +Create an AVD in the android UI, don't even try to get the data partition size +right in the GUI, that is doomed to producing an AVD that doesn't work. +Instead start it from the console: + + LD_LIBRARY_PATH=$(pwd)/lib emulator-arm -avd <Name> -partition-size 500 + +where <Name> is the literal name of the AVD that you entered. + +[ In order to have proper acceleration, you need the 32-bit `libGL.so`: + + sudo zypper in Mesa-libGL-devel-32bit + +and run emulator-arm after the installation. ] + +Then you can run `ant`/`adb` as described above. + +After a while of this loop you might find that you have lost a lot of +space on your emulator's or device's `/data` volume. You can do: + + adb shell stop; adb shell start + +## Debugging + +First of all, you need to configure the build with `--enable-debug` or +`--enable-dbgutil`. You may want to provide `--enable-symbols` to limit debuginfo, +like `--enable-symbols="sw/"` or so, in order to fit into the memory +during linking. + +Building with all symbols is also possible but the linking is currently +slow (around 10 to 15 minutes) and you need lots of memory (around 16GB + some +swap). + +### Using ndk-gdb + +Direct support for using `ndk-gdb` has been removed from the build system. It is +recommended that you give the lldb debugger a try that has the benefit of being +nicely integrated into Android Studio (see below for instructions). +If you nevertheless want to continue using `ndk-gdb`, use the following steps +that are described in more detail here: <https://stackoverflow.com/a/10539883> + +- add `android:debuggable="true"` to `AndroidManifest.xml` +- push `gdbserver` to device, launch and attach to application +- forward debugging port from host to device +- launch matching gdb on host and run following setup commands: + - set solib-search-path obj/local/<appAbi> + - file obj/local/<appAbi>/liblo-native-code.so + - target remote :<portused> + +Pretty printers aren't loaded automatically due to the single shared +object, but you can still load them manually. E.g. to have a pretty-printer for +`rtl::OString`, you need: + + (gdb) python sys.path.insert(0, "/master/solenv/gdb") + (gdb) source /master/instdir/program/libuno_sal.so.3-gdb.py + +### Using Android Studio (and Thus lldb) + +Note that lldb might not yield the same results as `ndk-gdb`. If you suspect a +problem with `lldb`, you can try to manually use `ndk-gdb` as described above. +Using `lldb` from within Android Studio is more comfortable though and works like this: + +- open `android/source/build.gradle` in Android Studio via File|New → Import Project +- make sure you select the right build variant (`strippedUIDebug` is what you want) +- use Run|Edit Configurations to create a new configuration of type "Android Native" + - on tab "General" pick module "source" + - on tab "Native Debugger" add `android/obj/local/<hostarch>` to + the Symbol directories + - on the LLDB startup commands tab add + "command script import `/path/to/solenv/lldb/libreoffice/LO.py`" + to get some pretty printing hooks for the various string classes + +Then you can select your new configuration and use Run | Debug to launch it. +Note that `lldb` doesn't initially stop execution, so if you want to add +breakpoints using lldb prompt, you manually have to pause execution, then you +can switch to the lldb tab and add your breakpoints. However making use of the +editor just using File|Open .. to open the desired file in Android Studio and +then toggling the breakpoint by clicking on the margin is more comfortable. + +### Debugging the Java Part + +Open `android/source/build.gradle` in Android studio via File|New → Import +Project and you can use Android Studio's debugging interface. +Just make sure you pick the correct build variant (strippedUIDebug) + +The alternative is to use the jdb command-line debugger. Steps to use it: + +1. Find out the JDWP ID of a debuggable application: + + adb jdwp + + From the list of currently active JDWP processes, the last number is the just +started debuggable application. + +2. Forward the remote JDWP port/process ID to a local port: + + adb forward tcp:7777 jdwp:31739 + +3. Connect to the running application: + + jdb -sourcepath src/java/ -attach localhost:7777 + +Assuming that you're already in the LOAndroid3 directory in your shell. + +### Debugging the Missing Services + +Android library only include essential services that are compiled for +LibreOffice in order to reduce the size of the apk. When developing, +some services might become useful and we should add those services +to the combined library. + +In order to identify missing services, we need to be able to receive +`SAL_INFO` from `cppuhelper/source/shlib.cxx` in logcat and therefore identify +what services are missing. To do so, you may want add the following +when configuring the build. + + --enable-symbols="cppuhelper/ sal/" + +[TODO: This is nonsense. `--enable-symbols` enables the `-g` option, not `SAL_INFO`. +Perhaps this was a misunderstanding of meaning of `--enable-selective-debuginfo`, +the old name for the option.] + +Which services are combined in the android lib is determined by + + solenv/bin/native-code.py + +### Common Errors / Gotchas + + lo_dlneeds: Could not read ELF header of /data/data/org.libreoffice...libfoo.so +This (most likely) means that the install quietly failed, and that +the file is truncated; check it out with `adb shell ls -l /data/data/...` + +### Startup Details + +All Android apps are basically Java programs. They run "in" a Dalvik +(or on Android 5 or newer - ART) virtual machine. Yes, you can also +have apps where all *your* code is native code, written in a compiled +language like C or C++. But also such apps are actually started +by system-provided Java bootstrapping code (`NativeActivity`) running +in a Dalvik VM. + +Such a native app (or actually, "activity") is not built as a +executable program, but as a shared object. The Java `NativeActivity` +bootstrapper loads that shared object with dlopen. + +Anyway, our current "experimental" apps are not based on `NativeActivity`. +They have normal Java code for the activity, and just call out to a single, +app-specific native library (called `liblo-native-code.so`) to do all the +heavy lifting. diff --git a/android/default-document/example.odt b/android/default-document/example.odt Binary files differnew file mode 100644 index 000000000..3aa6bb511 --- /dev/null +++ b/android/default-document/example.odt diff --git a/android/mobile-config.py b/android/mobile-config.py new file mode 100755 index 000000000..5998e5d1f --- /dev/null +++ b/android/mobile-config.py @@ -0,0 +1,116 @@ +#!/usr/bin/env python3 +# -*- tab-width: 4; indent-tabs-mode: nil; py-indent-offset: 4 -*- +# +# This file is part of the LibreOffice project. +# +# This Source Code Form is subject to the terms of the Mozilla Public +# License, v. 2.0.
