Remapping OAK remote STB Power/Vol+/Vol-/MUTE key for browser or Android APP usage

Introduction

This document describes a workaround that allows the keys that are normally forwarded to H200 OS directly, to be remapped to other Android/browser keyevents, making it possible for these keys to be used for other purposes.

Steps

In summary, we will be remapping the keys as described in the table below. Values in brackets are standard Android keyevent values.
(see https://developer.android.com/reference/android/view/KeyEvent for reference)

1. To remap the all of the keys in the table, we will add the following ini option for the STB.

keycode.remap.generic="26=177 24=253 25=254 164=252"

2. Reboot the STB with the new configuration.

3. Observe that the target key event would be triggered if the respective OAK remote key was pressed.

e.g. Use adb to connect to the STB and check the logcat output

When STB power key is pressed:

09-29 07:30:41.751 3937 4021 V WindowManager: start: cks.size() = 2 ck.key = 177 ck.time = 1664436641751
09-29 07:30:42.154 3937 4021 I InputReader: Amino: remap keycode: 177

When Vol + key is pressed:

09-29 07:30:00.945 3937 4021 V WindowManager: start: cks.size() = 4 ck.key = 253 ck.time = 1664436600945
09-29 07:30:01.134 3937 4021 I InputReader: Amino: remap keycode: 253

When Vol - is pressed:

09-29 07:36:19.253 3937 4021 V WindowManager: start: cks.size() = 3 ck.key = 254 ck.time = 1664436979253
09-29 07:36:19.550 3937 4021 I InputReader: Amino: remap keycode: 254

When Mute is pressed:

10-26 17:58:34.870 3822 3907 V WindowManager: start: cks.size() = 5 ck.key = 252 ck.time = 1666778314870
10-26 17:58:35.163 3822 3907 I InputReader: Amino: remap keycode: 252
