Rotary IME: Sample input method for rotary controller

This is a sample IME for use with a rotary controller. It is intentionally very basic so that it‘s easy to understand the code. It doesn’t support multiple locales / layouts. It doesn't support password fields, numeric fields, etc.

Building

make RotaryIME

Installing

adb install out/target/product/[hardware]/system/app/RotaryIME/RotaryIME.apk

Using

Once installed, configure the rotary_input_method string resource in the CarRotaryController package to refer to this IME:

    <string name="rotary_input_method" translatable="false">com.android.car.rotaryime/.RotaryIme</string>

Then build and install CarRotaryController. There is no need to enable this IME or select it; the RotaryService will select it automatically in rotary mode.
