Compiling GNU Nano for Android
By admin | July 13, 2012
If you just want a pre-built, ready to use version of Nano for Android, you can get the pre-built version.
The results of these steps include:
- GNU Nano 2.2.6 with statically-linked libncurses
- Compatibility with ≥ Android 2.1
- A working enter key, in adb shell and Term.apk
- A terminfo package
