[FREE] [OPEN SOURCE] Keyboard/Button Mapper [NO ADS] [4.4+]

[runtime64]

There is no other app that would work because the accessibility API is the only way for an app to (legally) remap the buttons. There are apps for Xposed I'm pretty sure but they use a completely different method that can remap all buttons. But that is Xposed.

Thank you again!

Thank you again!

Just for note, GravityBox with XPosed worked in my case to remap the main menu buttons.

I see, thanks again. Would you suggest to try another key mapping app that might work with these three buttons? I use yours for the fingerprint spot and fidn it just great. I'd like to get a more flexible management of the main menu.

You can try using a bluetooth/external keyboard to record the trigger. I successfully logged them but didn't try changing them.

If you don't have Bluetooth keyboard then you can check this app "Serverless Bluetooth Keyboard by AppGround IO" on some other device to make that device serve as Bluetooth keyboard. I captured the triggers using this method only.

@sds100 Is there any way to log/check why the app fails after some time despite satisfying all requirements (Accessibility, Keymapper keyboard etc)? I am using Huawei Tablet but have disabled battery optimisations as well as disabled auto-management by Huawei software but the app seems to be losing key captures.

I'm using Bluetooth keyboard and keymapper successfully changes the input method to Keymapper keyboard but doesn't capture keys.

Edit: It works after disabling and re-enabling Accessibility for Keymapper. But doing this every now and then this would defeat the whole purpose of using the app :/

Hello @sds100 ,

Thanks for this app first of all. I just got a new phone and decided to use this app instead of "button mapper" that I was using for my Xiaomi Mi 9. Because this app has the "vol up + vol down" combo.

Basically with my Mi 11, what I want to do is to press vol up + vol down and the flashlight turns on. Very convenient especially at night.

It works great, except when the screen is off, in which case I have to give it a tap so something gets displayed (usually the fingerprint graphic) and then the vol up and down works again.

I doubt the process gets killed, because it works everytime when something is displayed even when phone is locked. And if always on is enabled, then it always works.

Again thanks for this app !

Sorry that I missed this. Other people have reported this issue on some devices but I have never been able to reproduce this. Does the latest 2.3.0 release in the github repo fix this?

Hi!
Unfortunately Android doesn't allow accessibility services to detect the button presses when the screen is off. There is no solution for this. There are only very very restrictive "solutions" for this which won't allow you to do what you want to do.
Have a good day!

@sds100: Just want to thank you for developing this app! It is the first app that allowed me to do what I wanted to do on my device, and I tried a number of apps and approaches.

Recently, I bought a Nook Glowlight 4. That is an E-ink reader with a six inch display that runs Android 8.1. There's no obvious way to install apps, but with a little hunting, I found where such things as developer settings were hidden. That opened the door to ADB, which allowed me to install a launcher and a few apps, mainly reader apps.

The Nook has physical page-turn buttons. Well, I wanted to see if I could set things up so that those buttons would be functional on my third party reader apps. I rooted my device and tried a few options. Your app was the only one I found that allowed me to have a setup where the page-turn buttons would work on both the Nook stock reader and the third party apps! B&N did a few weird things with the way the Nook is set up, which makes finding your app all the better.

Thanks again!

Hi! I'm happy to hear that you like the app . It is always great to hear the cool ways people find to use this app.

Hi! I'm happy to hear that you like the app . It is always great to hear the cool ways people find to use this app.

What did the trick for me specifically was the ability to have a physical button simulate a tap on the screen. That allowed me to use the physical buttons with apps that are not coded for use with physical buttons.

A few years ago, someone came up with a complicated way to achieve something similar with an Android E-ink device, using Tasker and Xposed. Your app does all that for me, and far more simply! Thanks again!

Love this app! Is it possible to include "work profile" apps to make them addressible for action targets?

Hi! Are you wanting to use the "open app" action?

 

[chnzshyguy]

Hi! Are you wanting to use the "open app" action?

Yup! For "open app" actions, it doesn't list the apps from my work profile. Is it possible to add that? I am using a Samsung Galaxy Tab S7.

 

[sds100]

I'm not sure but I will add it to the issue list https://github.com/sds100/KeyMapper/issues and will check it out some time. I don't have much time to work on the app right now so I'm not sure when I will add this.

Getting "unknown keycode 0" when remapping bluetooth remote control?

So I'm using Key Mapper on Chromecast w/ Google TV so adding a customed .kl file is out of question (no root). I got a Xiaomi bluetooth remote control, codename XMRM-010. It's not supported by default on GwGTV but I managed to pair successfully using a bluetooth manager app.

Problem is all of the programmable buttons get an "unknown keycode 0" when I try to map them. I found this app "External Keyboard Helper Pro" and it could recognize all the buttons and their respective scancodes. Only issue is it only works as an input method a.k.a when focus is on an input field (on-screen keyboard is needed) and hasn't been updated since 2016. No service appears in accessibility.

Therefore I'm pretty sure this "unknown keycode 0" is on the app level and can be resolved with an update of scancode database? Or at least something like a "manually input scancode" feature if possible?



Replicating the issue on my tablet for the sake of better screenshots but everything else is accurately the same. Issue on Key Mapper

External Keyboard Helper Pro can recognize all scancodes (3 digit numbers) and map them correctly. The keycodes I chose here were for reference but others like (Search, Back, Home,...) do work
