Using tasker to switch talkback on or off via press of a key etc

Hi. I am trying to get my head round this tasker. I have learnt it to some extent, and can create profiles / tasks.
However, what I am trying to do (its for my blind wife really) is create a simple toggle that can be placed on the home screen or a toggle via a button press / combo to turn talkback on or off.
I have got as far as getting to the accessibility page with a keypress, but I`d like to actually TURN talkback on or off, instead of just getting to the accessibility screen (where I have to go into talkback and turn it on/off - hugely inconvenient if you need to go back and forth in apps).
I have tried other apps like Home2 shortcut which... gets me to accessibility screen
Anycut... accessibility screen
Xshortcut (really hoped this would work as it can "record" your actions... but get a permissions error)... no dice.
Can anyone PLEASE help me to accomplish this, it would hugely benefit the blind community, this is a big fail on googles part IMHO
Thankyou
Matty
I`m unsure if google allows this?

Hallo Matty
I've run into the same issue in trying to set up Talkback on my dad's phone. I see there was no response to your post. Did you find a solution elsewhere by any chance?

[APP][WIP][DEVS NEEDED] Hands Free Now [ALPHA]

HANDS FREE NOW​
Hands Free Now is an attempt to fix the bug in Google Now that Google itself never fixed.
As most of you know, as of Android 4.1+, our headsets are configured to work as follows:
1. Single press for play/pause
2. Double press for next
3. Long press for Google Now
However, the long press option does not work when the screen is off. It works only when screen is on. This is a bizarre lack of feature because if the screen is on and unlocked, you might as well click the mic on the desktop widget to launch Google Now. Why would you need the long press option anyway?!
Several attempts were made by many people to bring Googler's attention to this lack of feature, but all of em were conveniently turned down.
So I guess it's up to us to fix it.
I have started making this app but being the newbie that I am, I'm not sure if I can finish it alone. That's why I request you guys to help me out with this.
Uploaded below is the first apk
Concept in brief:
1. Launch Audio service that intercepts media KeyEvents
2. Once KeyEvents are triggered, create an empty StandOut window that blocks the entire display.
3. Wake up device, disable keyguard and launch Google Now
4. Release wakelock immediately. and reenable keyguard
5. Kill process in 10 seconds
Steps to use:
1. Install app
2. Open app from launcher once. You can go back to Home after this if you want
3. Lock screen.
4. Jack in the head set and triple press the button.
5. Device should unlock itself and in some time will launch Google Now
6. Fire your voice command and wait for response.
7. In 10 seconds, the screen will lock again.
8. For these 10 seconds, your phone will not respond to touches (this is intentional and by design, because you would not want your phone to "pocket dial" while travelling)
Release Notes:
1. App is currently incompatible with music players
2. Battery effectiveness is unknown; you might have to uninstall it once you have tested it
If you can help, the source code can be found on GitHub.

Installed app, but it wont launch after 3 presses of the button, I get a double beep sound when doing so.
I can help out with testing if you want but as far as coding goes im not very useful xD

Bluetooth too?
Will it work with Bluetooth headsets as well or only wired ones?

THANK YOU!
I registered just to say thank you, your little app allowed me to have the kind of music control I alway longed for since i passed from iPhone to Nexus 5. I'm truly grateful.:good:

I had the problem when the screen was off. After when I long press the little button on my headset. Then comes a black screen with a message: please wait (initializing) but nothing does.
But this app solve my problem!
Now I can use Google Now over my Headset.
Thank you very much! ?

Seems an old thread, but nevertheless: Thank you! Finally it works!
I'm just curious if it would be possible to change add long-press functionality. The app AutoVoice is capable of receiving a long press (also with locked screen). But it doesn't help because it relies on the not working Google Search.
Possible idea: your App could register as a service capable of receiving the VOICE_SEARCH_HANDS_FREE intent, it could receive the long press and start its procedure. It won't work immediately because Android will display the "Choose default app" prompt, that obviously doesn't work when the screen is locked/off. In order to choose the default app one has to wake the screen and manually override the keyguard/lock (for example via Secure Settings Plugin and Tasker). The override is somewhat buggy, and even though the screen is on, the phone still 'thinks' it's locked. Now: long-press to receive the command for long-press while locked, see menu and select default app. ..Hope my explanation isn't too bad.
I'm investigation another workaround to get it working with music player.
Best regards, Grtschnk

Make home button launch S Voice?

Is there a way to change the function of long pressing the Home button from launching Google Now to launching S Voice? I already tried All in One Gestures, but that didn't do the trick.

After installing Tasker and then long pressing the home button I was asked whether to use Google Now Launcher or Tasker to complete the action. You may be able to have Tasker then launch S-Voice or whatever app you'd like.
I was thinking of doing the same but instead executing the "OK Google" equivalent.

Great idea! Thank you

Start google voice recognition with button press when screen locked - Android M

I want to start google voice recognition if I press a hardware button when the phone is connected to bluetooth and the phone is in my pocket. The button on my car directly calls the contact and I don't want that. I wanted it to start google voice recognition which then listens from the car bluetooth mic, but I couldn't find a way to change this default behaviour of the bluetooth key.
Anyway, then I tried to start google voice recognition after pressing the power button of the phone and after the display is on with tasker, but it also doesn't work if I don't completely pass the lock screen even if the device is unlocked (lock is disabled because of secure bluetooth connection). I tried everything I found including disabling the keyguard, different google now intents but I couldn't find any solution. Ok Google command works even if the screen is off, but I couldn't find a way to start the voice recognition manually even when the display is on and not locked (but on lock screen). How can I do that from the lock screen with the device unlocked, or if I can't, how can I pass the lock screen and go to the home screen? By unlocked I mean that the phone does not require any password/pin to unlock it, just sliding on the lock screen is enough.

So, no way to start google now voice recognition when on the lock screen?

Question [SOLVED] Wake Phone With Watch

I am wondering if there is a simple way to wake a phone's screen from the watch, similar to selecting "Edit on phone" when selecting a new watchface?
I finally have a working VNC viewer on my watch, but none of the commands will wake the phone's screen, even if the phone is already unlocked. I can wake the phone with a BT keyboard just by pressing the space bar, or some other keys, but it doesn't seem to work from the watches keyboard. From my understanding, a tasker might do the trick, but am wondering what your thoughts are? Thanks!

Ah, never mind. It was an issue with the VNC server on my phone. After updating the app, the screen wakes upon connecting.

FYI: If anyone wants another method of waking their phone from their watch, a remote input app such as WearMouse works.
