I started a project to use my old galaxy S4 as a Google assistant and a chromecast all at once. I have the google assistant part working and the casting apps installed. Its just down to fine tuning now and getting both to work correctly. This project originally started with just using the phone as a google assistant and then I thought why not add chromecast. The S4 supports MHL so I figured ill get a dock and go from there (the dock has yet to arrive).

Here is my setup for all those who wish to follow, help or provide input.

-Galaxy S4 rooted with stang5litre Ediition 5.0 rom.

-Installed google assistant via google assistant launcher here: https://forum.xda-developers.com/and...oogle-t3614804

NOTE: The above app may not be needed cuz my limitation was getting an updated google to install on android 5, I got the assistant app fine. Your results may vary. I got updated google search via apk and was off and running.

Once I got the assistant installed I paired it with a bluetooth speaker and had 2 issues.

1. Bluetooth not staying connected & audio not coming through the speaker. It was just a matter of finding the right speaker and then playing with it.

2. I also had the screen off issue where assistant would not respond and had to get daydream to work. I also tried this app: https://forum.xda-developers.com/sho....php?t=1934495
The problem with screen standby is it wont respond to assistant calls when it triggers, but I might need to go back to it when the doc arrives. The daydream screensaver I have now is clock plus which has a dim to nearly dark features. So that works for assistant to stay active.

-Chromecast ability: I installed 2 apps for chromecast like affect. 1. Airpin (airplay) and 2. allcast receiver. I tried airscreen but that dev wants to much money for such a simple app. Now I know neither of these offer true chromecast support and airscreen is the only 1 that does offer the real deal (it even shows up in the google home app, impressive).

-My next step is to see if I can cast to the device and keep assistant around in the background. I know this will be the most challenging part because of the following:

1. Audio to both bluetooth and TV speakers or maybe I can use a wired speaker for when the TV is off. I'd like to be able to do this all without getting up to fix anything. Will see.

2. Google assistant popping up in front off chromecast app, I'm not sure if I can somehow address this and ask assistant to bring app to front. Maybe impossible and Ill have to use a bluetooth remote.

Input thoughts on this project?

I guess no one cares about this, the state of device obsolescence is so high that a new device is what everyone wants instead of looking for fixes and uses for old devices. Everyone rather move on and move up to something new, easier & better. XDA used to be full of mods, hacks and tricks to use old tech, NO MORE! Everyone seems to be falling for big tech BIG deception. Is it really this bad? Are we all just going to stab mother nature in the back just because we rather have something new, & throw away something old?

Enough of the rant: I got this working and its better then I could imagine. The unitek smart phone dock is great for the S4. Google assistant works via the hacks and keeps connected to my bluetooth speaker despite the tv turning on. The logitech keyboard also works via OTG perfectly. So I can keep assistant working and all I need to do is run allcast or airpin and the audio will continue through bluetooth up until I turn bluetooth off. I like that cuz all I need to do is disconnect bluetooth and TV (hdmi) takes over audio. One thing I noticed is that airpin will not work but allcast does fine, ill have to figure out why airplay does not work but I do know the difference between allcast and airpin is that chromecast is a handoff and airplay is not, so it could just need an update. I could also easily turn this into a android tv with a launcher swap and a few tv apps, but for now I prefer chromecast type device.

The best thing about this is that once I'm done using the cast features I can go right back to it being a google assistant without skipping a beat which I was concerned would cause some kinda hickup with the daydream screen function & MHL. I figured I might need something like screen standby (see: https://forum.xda-developers.com/sho....php?t=1934495) but I actually did not, which is a big surprise. The screen just goes off when MHL is used and back on (including daydream function) when tv turns off.

Anyway that's a wrap on this project 100% success. If anyone has any questions let me know I'll try to help.

This sounds interesting but if I need an additional accessory, its not really worth it cuz a chromecast literally costs 35 bucks.

Also, this looks interesting.

If we can port that over to our device, then we can assign google assistant to the bluetooth speaker and every other sound should come out from the tv.

Google home app
Yes, Airscreen is the real deal and the only store app I've found that actually does work with Google on my old s5 android to stream from new note9 android. so I bought the cheap premium monthly subscription. However I can't get it to show in the home app, just in Google play and YouTube.
