• cd working_dir
• git clone https://android.googlesource.com/platform/packages/inputmethods/LatinIME LatinIME
• cd LatinIME
• create "AOSP-LatinIME-for-explicit-behavior-modification-study" github repo

• add gitignore
• git commit -m "added gitignore"
• git push -u origin master

Create the Android Studio Project

• mkdir AOSP-LatinIME-ebm-study-Android-Studio
• cd AOSP-LatinIME-ebm-study-Android-Studio
• git clone https://github.com/iwo/LatinIME-Android-Studio.git .
• create "AOSP-LatinIME-ebm-study-Android-Studio" github repo
• git remote set-url origin https://github.com/MatKier/AOSP-LatinIME-ebm-study-Android-Studio.git
• update gitignore
• update build.gradle
  • add https://maven.google.com/, jcenter() and google() to repositories
  • update gradle classpath
  • add google-services to classpath
• update app/build.gradle
  • update compileSdkVersion, buildToolsVersion, minSdkVersion, and targetSdkVersion
  • add jniLibs.srcDirs = ['../app/src/main/jniLibs'] to sourceSets
  • uppdate dependencies
• get libjni_latinime.so libs
  • pre built or by compiling from the AOSP (see "Building libjni_latinime.so")
  • put the libs in app/src/jiLibs
• git submodule add https://android.googlesource.com/platform/frameworks/opt/inputmethodcommon
• git submodule add https://github.com/MatKier/AOSP-LatinIME-for-explicit-behavior-modification-study.git LatinIME
• cd LatinIME
• git checkout master
• cd ..
• git commit -m "added submodules and jniLibs"
• git push -u origin master

Building libjni_latinime.so

• Basically follow these instructions: https://source.android.com/setup/build/initializing
• In short (for only building the library and not the complete AOSP):
  • Setup the Build Environment & Tools:

sudo apt-get update
sudo apt install git
sudo apt install python2.7 python-pip
sudo apt-get install openjdk-8-jdk

sudo update-alternatives --config java
sudo update-alternatives --config javac

sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev libgl1-mesa-dev libxml2-utils xsltproc unzip

• Install Repo and Download the Source (around 80Gb):

mkdir ~/bin
PATH=~/bin:$PATH

curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo

mkdir WORKING_DIRECTORY
cd WORKING_DIRECTORY

git config --global user.name "Your Name"
git config --global user.email "you@example.com"

repo init -u https://android.googlesource.com/platform/manifest

repo sync

• Building:
  • choose Platform with lunch (aosp_arm-eng, aosp_arm64-eng, aosp_x86-eng, aosp_x86_64-eng)

make clobber

source build/envsetup.sh

cd packages/inputmethods/LatinIME/native/jni

lunch aosp_arm64-eng

mma

• libjni_latinime.so now sits in out/target/product/generic_arm64/system/lib64
