The development of this Android app has to be done on Linux, it's currently not possible to
|
|
build the native parts on Windows.
|
|
|
|
* Compile LibreOffice master for Android.
|
|
|
|
Do this in the folder where you cloned the LibreOffice core (e.g master-android).
|
|
|
|
Create an autogen.input file:
|
|
|
|
--build=x86_64-unknown-linux-gnu
|
|
--with-android-ndk=/home/$USER/Android/Sdk/ndk-bundle
|
|
--with-android-sdk=/home/$USER/Android/Sdk
|
|
--with-distro=LibreOfficeAndroid
|
|
--enable-sal-log
|
|
|
|
Run ./autogen.sh && make
|
|
|
|
* Build the POCO for Android
|
|
|
|
# clone the poco repository in the same folder where LibreOffice core and online folders are placed.
|
|
git clone https://github.com/pocoproject/poco poco-android
|
|
cd poco-android
|
|
|
|
# use the 1.9.1 branch
|
|
git checkout -b poco-1.9.1 origin/poco-1.9.1
|
|
|
|
# configure
|
|
./configure --config=Android --no-samples --no-tests --minimal
|
|
|
|
# make it
|
|
PATH="$PATH":~/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin make -j8 ANDROID_ABI=armeabi-v7a CC=armv7a-linux-androideabi21-clang CXX=armv7a-linux-androideabi21-clang++ SYSLIBS=-static-libstdc++
|
|
|
|
# install it to /opt/poco-android
|
|
PATH="$PATH":~/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin make -j8 ANDROID_ABI=armeabi-v7a CC=armv7a-linux-androideabi21-clang CXX=armv7a-linux-androideabi21-clang++ SYSLIBS=-static-libstdc++ install INSTALLDIR=/opt/poco-android
|
|
|
|
* Configure the online.git (eg. in online-android folder)
|
|
|
|
Don't forget to change --with-lo-builddir in the following:
|
|
|
|
./autogen.sh && ./configure CC=~/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin/armv7a-linux-androideabi21-clang CXX=~/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin/armv7a-linux-androideabi21-clang++ --host=arm-linux-androideabi --enable-androidapp --with-lo-builddir=/local/libreoffice/master-android --with-poco-includes=/opt/poco-android/include --with-poco-libs=/opt/poco-android/lib --disable-setcap --enable-silent-rules --enable-debug
|
|
|
|
* Build the JavaScript, HTML and CSS files also in the online-android folder
|
|
|
|
# just run 'make'
|
|
make
|
|
|
|
* Build the actual app
|
|
|
|
+ Start Android Studio
|
|
+ Open this 'android' subdir as a project
|
|
+ Build from Android Studio (Build -> Make Project)
|
|

== Tip: How to speed up your core.git build ==
|
|
|
|
If you use icecream for parallel building, you can use it for
|
|
cross-compilation too.
|
|
|
|
# first generate a tarball with the toolchain (once)
|
|
icecc-create-env ~/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin/armv7a-linux-androideabi21-clang ~/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin/armv7a-linux-androideabi21-clang++
|
|
|
|
And add it and the paths to the compiler as the first things to the
|
|
autogen.input:
|
|
|
|
CC=icecc [here copy what the output of ./autogen.sh without icecream said for C compiler]
|
|
CXX=icecc [here copy what the output of ./autogen.sh without icecream said for C++ compiler]
|
|
ICECC_VERSION=/path/to/the/tarball/generated/above/955ceb546ceb7a5715bf0223ddd788fe.tar.gz
|
|
--with-parallelism=[amount of cpu threads in your icecream farm]
|
|
--enable-icecream
|
|
[...the original autogen.input...]
|
|
|
|
So the result will look something like this:
|
|
|
|
CC=icecc /home/$USER/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin/clang -mthumb -march=armv7-a -mfloat-abi=softfp -mfpu=neon -Wl,--fix-cortex-a8 -gcc-toolchain /home/$USER/Android/Sdk/ndk-bundle/to>
|
|
CXX=icecc /home/$USER/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin/clang++ -mthumb -march=armv7-a -mfloat-abi=softfp -mfpu=neon -Wl,--fix-cortex-a8 -gcc-toolchain /home/$USER/Android/Sdk/ndk-bundle>
|
|
ICECC_VERSION=/local/libreoffice/android/955ceb546ceb7a5715bf0223ddd788fe.tar.gz
|
|
--with-parallelism=25
|
|
--enable-icecream
|
|
--build=x86_64-unknown-linux-gnu
|
|
--with-android-ndk=/home/$USER/Android/Sdk/ndk-bundle
|
