While building roms for the Samsung Galaxy Note Edge (TBLTETMO, TBLTEXX) I ran into an issue where the recents button was not working. So, I pulled a logcat, and here is what I saw:

KeyEvent { action=ACTION_UP, keyCode=KEYCODE_UNKNOWN, scanCode=254, metaState=0, flags=0x208, repeatCount=0, eventTime=182478, downTime=182375, deviceId=18, source=0x101 }

This lead me on a wild goose chase accross the internet, but praise God, I caught that goose!

Here is the article that helped me the most:

However, it was only close to solving my issue. Sometime between 2010 and now, Android stopped using qwerty.kl as the main file for setting the keymap. So, I also had to edit Generic.kl to make it work.

Here is the whole thing if you are doing this on your phone:

Using ES File Explorer or similar, open /system/usr/keylayout/Generic.kl.

Go down past “key 226 HEADSETHOOK”
and add “key 254 MENU”

Save and close that.

Then, open /system/usr/keylayout/qwerty.kl.

Go down past “key 212 CAMERA”
and add “key 254 MENU”

Save and close that.

Then, open /system/usr/keylayout/sec_touchkey.kl.

Edit “key 254 MENU”

Save and close that.

Now, reboot your phone and the recents button will be a menu button!

If you are editing your source code, you can see the commit I did and do likewise, here:

Essentially, I added the Generic.kl file from my phone to my build, and made the build copy it over when making a rom. Pretty simple, once you know what to do!

Linux – keep it simple.
