An Android app with a convenient UI that pushes blog posts to my Github Pages site. Stores the remote repo link and Github credentials in an sqlite db.
This app uses a git binary cross-compiled for arm. You could probably cross-compile it from source yourself, but an easier way to
get your hands on the binary is to just install Termux, run apt install git, and then copy the git, git-receive-pack, git-upload-archive, and git-upload-pack binaries from /data/data/com.termux/files/usr/bin to /system/bin. (You'll probably need to be root to do this.) git is linked dynamically, so you'll also need to run ldd /system/bin/git and copy all of the required libs from /data/data/com.termux/files/usr/lib to /system/lib, then run patchelf --set-rpath /system/lib /system/bin/git. Otherwise the binary will still look for libs in Termux's lib folder, and your app won't have permission to access that folder (unless you chown to make your app, u0_aXXX, own all of Termux). Anyways, you need to uninstall Termux completely from your device, otherwise git will still try to look for a config file in /data/data/com.termux and will be denied permission.
Without Termux installed, you'll likely also have problems with git pull and git push. (Error msg "git: 'remote-https' is not a git command."). I'm working on a more robust solution for using the git binary on Android.
If you still want to have Termux installed on your device, you can create your own full clone of Termux with a different package name.
You'll probably need to run git config user.name and git config user.email to get things working.
An alternative solution would be to use JGit or sheimi's SGit. I used bits and pieces of both in this project.
