minikey

Minikey provides a command line interface to send and receive keyboard events on KaiOS devices. Minikey implements the mapping between physical keyboard and KaiOS internal input events via the libevdev interface.

Minikey may be used by any test tool for test automation. You can record keyboard events and then replay events as you want.

Note: Minikey has been tested only on Nokia 8110 with the following [mapping table] (MAPPING.md).

Building

Building requires NDK (revision 10 at least). Project include LIBEVDEV as a GIT submodule to initialize first:

git submodule init
git submodule update

Then use the command ndk-build from your Android SDK (see your directory $ANDROID_SDK/ndk-bundle).

ndk-build

You should now have binaries available in a directory ./libs.

Deploy on device

You can use the included run.sh script to build and deploy the right binary on your device.

Or manually, you have to first detect which ABI (Application Binary Interface) your device supports:

ABI=$(adb shell getprop ro.product.cpu.abi | tr -d '\r')

Now, push the appropriate binary to the device:

adb push libs/$ABI/minikey /data/local/tmp/

Note that for SDK < 16, you will have to use the minikey-nopie executable which comes without PIE support. Check run.sh for a scripting example.

Usage

Display the command help:

adb shell /data/local/tmp/minikey -h

Usage: /data/local/tmp/minikey [-h] [-w key] [-r input] [-i] [-f file]
  -w <key>  : Write keys.
  -r <input>: Read keys from a given input (eg. '/dev/input/event0' or 'all' for all inputs at a time).
  -i        : Uses STDIN to send key values.
  -f <file> : Runs a file with a list of commands, doesn't start socket.
  -h        : Show help.

Send one or several key press events (see also the [mapping table] (MAPPING.md) for special keys):

adb shell /data/local/tmp/minikey -w 123pdo

Send one or several key press events from a file:

adb shell /data/local/tmp/minikey -f keys.txt

Send one or several key press events from STDIN (press to send values):

adb shell /data/local/tmp/minikey -i

Read key events from a given input:

adb shell /data/local/tmp/minikey -r /dev/input/event0

Read key events from any input event:

adb shell /data/local/tmp/minikey -r all
