h1. Porting Replicant to Android 9 h2. Status * The Galaxy SIII 4G (i9305) boots (with graphics hacks) under AOSP9, without having to import nonfree libraries. Not much has been validated beside that. * The kernel used is based on Linux 5.0-rc6 and has ~150 Android specific patches on top and some patches for the Galaxy SIII 4G (i9305) on top h2. Repositories and changes * git://git.putti.eu/aosp/manifest_i9305.git * git://git.putti.eu/aosp/kernel_i9305.git * git://git.putti.eu/aosp/device_i9305.git h2. Building First get the source code: <pre> $ repo init -u git://git.putti.eu/aosp/manifest_i9305.git -b android-9.0.0 </pre> For Trisquel8 (WIP): <pre> 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 bc python-mako </pre> Then see the device/putti/i9305/README.md for the build instructions. h2.
