[Q] Android device cluster, networking or screen sharing

In short: Is it possible to cluster, network or push device output from one device to another, share storage devices and network/gps interfaces?
The long version: I have been wanting to build an in-car device that would store media and act as a gps and what not, but haven't found a way that I want to implement it yet. I was thinking if I found a x86 port of android, got most of the voice stuff working, I could have a headless device that I could store music on and use as navigation. I know the phones are capable of that, but if I want to keep say 500 gb of music on me, how does one do that?
My thoughts were if it were possible to either cluster or network an installed android powered unit to an android powered phone, I could always have network access from the unit in the car and share the gps from the phone, or have the phone access the storage from the device (not through dlna, but the music app seeing it as physical storage) and allow me to push the output from the in car device to the phone and let me interact with the system how ever I need to I could accomplish a form of in-car entertainment.
I figured that there could be apps written that would let the in-car device act as a headless unit, with its only interface being audio, it could store navigation directions/maps and what not, so if I didn't have the phone that day, I could still navigate to where I needed to. The phone and the device could constantly be in communication with each other if the car was parked by a wifi hotspot or something, so if I chose to navigate somewhere when I was at home, the car would already have the directions. I could also have it pull any media changes through wifi, and always have an updated media library.
I know the phones are fully capable of doing this, but for most of it, you have to have a window holster for the car to use the gps, and wires running for audio and charging and what not, but if there were a way that the in-car device could be hardwired to the audio system and left alone, the phone could stay in my pocked, be linked via bluetooth and I could have a small button-pad or something that would allow me to initiate google voice search, control the media player and interact with navigation. The whole thing with linking the phone and device together would be so the mobile network could be shared between android devices and the incar device could pull the information it needed. The thought of the display sharing was in case I needed to interact with the incar device.
I know what I am going on about is specific to me, but my thoughts behind it were if it were possible to do at least the network sharing (with out tethering or mobile hot spot blah blah blah) that android phone and tablet owners could do the same thing. They could share their mobile network through their tablet and have a tablet that would be always connected, would share mailboxes with the phone and basically act the way the Blackberry playbook is proposed or how the Palm Foleo was supposed to work. If the devices had a network ability of some level, the tablet could pull text messages, email messages, contacts or any other sync-able item.. That way, this wouldn't just be done for my benefit, but it would take tablet and phone owners to another league. Two devices that share the same information from one source and don't have to sync with the same servers twice. It would take a lot of redundancy out.
I hope you guys can see usefulness in my idea, and can shed some light for me.

Sorry from bringing this back from the dead, but since I never got any responses I'll add a bit more..
Does android have anything that would work like blackberry bridge between two android devices?

Droid Vnc server and androidvnc works fine for screen sharing. What I really like is the hpc aspects to CPU cycle sharing over wifi/nfc. Really interesting possibilities.

What I am looking for is to have the ability to use two separate android devices, but have them communicate via wifi/bluetooth or what ever and act as the same device in the sense that when the device with the data plan gets a text message or phone call, the notification goes through the other device that would be physically docked to audio equipment or what ever...
I have a Droid X, Droid Incredible, Droid Pro and a first gen Droid laying around.. Currently the Droid Pro is my in use phone.. The rest are just laying here. I want to be able to dock one of the others in my car, turn the GPS on, link it to my droid pro and have the other phone use the droid pro's active data connection for guidance/searches etc, and it would be docked to car audio, so it would need to access the pro's sd card, and have access to the pro's phone audio, or the ability to route calls from the pro to the other device via bluetooth or whatever, not by call forwarding.. This way it would be a sort of infotainment/telematics system..
Think of the possibilities this would open up for android tablets etc. If You could reply to text messages from your tablet because the tablet is linked/bridged to the phone in your pocket... That would make these tablet/laptop combos more appealing because it would the perfect convergence between tablet and phone.

Oh, and I guess, the other thing is that I have multiple cars, so one device would go in each car, and then when I got in the car, the one in that car would link with my phone, and everything would be the same, car to car, or device to device...

I guess another way to bump this:
Would it be possible for an app to do ADB to ADB via bluetooth or something, because then an app could be written like pdanet that would allow the network to be shared at least?

I dont remember the name of the app I think the name of it is Dashboard? and it will store/push all texts/emails etc. to every device u have dashboard installed on...Best buy has an app kinda like that too...Like the Idea of the screen sharing is that kinda like remote desktop/control?

I just search how to neywork cluster android came across your post ..... if you use the Google apps like Google play music/maps as well Google hangouts since with Google voice you can easily do what you want with out the need for both devices being together you can upload 50000 songs 9n play music for free and any device with ur hangouts and voice will receive ur calls and email notifications .....just need to make sure have Internet

[HOWTO] Miracast Like a Boss - Offline Mirroring

First off, I get it. Chromecast is awesome and Miracast kinda sucks. I know. However, I was searching for an AIO video solution for my minivan that I could control from the 1st row (refuse to use DVDs - 2014 T&C has 1 HDMI port behind the 2nd row). My Chromecast works awesome tethered to my phone's hotspot. Other than for the first time setup, you don't even need a second device. You can cast from the device hosting the hotspot which is slick. Perfect for in-car. But I wanted to be able to cast local content so network reliability does not become and issue when traveling (Netflix, Emby, etc). Enter BubbleUPNP. Bubble will transcode on the fly (on the phone) and cast anything you have to your Chromecast (Chromecast is super limited on codecs). This was perfect for when I was in the car. But I needed a solution for my wife. Unfortunately, due to me holding on to my unlimited data on good 'ole VZW, my wife does not have native tethering enabled (iPhone - not going to JB it either). My idea was to get a deactivated phone (in this case, a Galaxy S5), enable the native hotspot, and use the Chromecast connected to wifi, but offline. Guess what Chromecast can't do...even for local content. Yeah. It needs the internet. So...
So I bought a Microsoft Wireless Adapter for Miracast. It is not too shabby actually. Hate that it mirrors everything (prefer the "cast" then use your phone normally and even turn the screen off), but it is fast and reliable. The problem was, the GS5 wouldn't connect to it (something like "failed to connect to screen mirroring"). Tried on Lollipop and Marshmallow with the same result. I found a build.prop edit that disables HDCP. This allowed it to connect with a minor exception. Netflix would not display its video (from my research, Hulu and others might be affected too). I figured this was due to the device being rooted, so I unrooted the device and re-enabled HDCP, but left everything else the same (unlocked dev bootloader, custom recovery, near-stock rom). Failed to connect. Well crap.
I finally rolled back to completely stock 5.0 (PB1) and tried again. Everything worked (including Netflix). Side-loaded the 6.0.1 update. It still worked. I'm not sure what breaks HDCP compliance, but something in the modification process does it. The good news is that since I don't need the native hotspot or any apps other than media players, I don't need root at all. I disabled all the crapware and done!
Popped in a 128GB microSD and loaded it up. Installed the newest Kodi nightly (to get the new estouchy skin for touchscreen use) and it works amazingly. Everything was named nicely already because of Emby, so once I added the TV shows and movies to libraries, Kodi pulled in all the art and metadata automatically. The only thing I don't like so far is that Kodi won't dim/shut off the phone's display like VLC does when you are mirroring (it's not really off, it just turns black). That's not a dealbreaker though, and it might be a feature that I just haven't found yet, or can add via an add-on.
Anyhow, I have no idea if this will help anyone, but I figured if I could save someone some time and a few headaches, it would be worth a quick write-up.
Note: I do have an MHL 2.0 to HDMI adapter. Mirroring a VZW GS5 with 6.0.1 works perfectly with this setup. I wanted to find a wireless solution to avoid cable clutter and potential damage to the phone's USB port.

Display slowly dying, options for using the phone without one?

The display on my S7 started slowly dying, I estimate it will be fully dead in a few weeks. A replacement costs almost 100$, not including work, so it's probably going to stay like it is. I still want to use the phone however, for app development or music or similar stuff.
Is there any way to mirror the display or use some kind of VNC? I don't have a smart TV but several computers, not sure if miracast works on those.
I would also like the mirroring to start automatically or at least through some adb command line, because I will likely not see anything on the screen.

Replying to myself: found a relatively good option that's also free: https://github.com/Genymobile/scrcpy

I've installed TeamViewer Host on my S7 and it works great over wifi. I tried controlling my android device from Windows, MacOS and another android device, but it should work on linux and ios too.

G7 power to tv

Looking for the best way to connect my g7 power to a Panasonic Viera non smart tv.
I pay for BT sport which works on my phone but trying to get it working on the larger screen, tried various apps and firestick mirroring but non seem to work.
Does anyone know if a cable is available that would work or is it not possible with my set up.

As far as I can find Motorola doesn't include support for video out over USB-C. USB to HDMI cables won't work.
Casting is the only option.

Thanks for replying
Do you think Chromecast would work
I've tried mirroring to the Firestick and although the g7 finds the the Firestick signal it asks for a password, that I've never set up and it's not the wifi password and I can't seem to find much info on it.

Should. Casting per app works better.
Not sure on the Amazon gear, never used one. I'd expect something in it's setup to set/show password. Maybe a few searches for help?

You can purchase a USB 3.0 laptop dock with DisplayLink technology to mirror your device directly to any HDMI enabled device.
I own one, and have been using it extensively for months now.
It is important to keep in mind, you do NOT want a USB C DOCK. A previous poster explained this device doesn't have all the extra circuitry, so you cannot pass a 'protected' stream through the dock. In other words, many apps won't display the video playback on the dock.
BUT!!!! Most, if not all, video services that have a website appear to play just fine mirrored (use the website, not the app!)

what model is your device?

The one this thread is about.
Or are you asking about my video out solution? Wavlink cube looking one.

G7 Power does not support Miracast, apparently. Only chromecast.

Google dropped Miracast from Android 6. So an OE has to add it back. Motorola is running nearly stock Android and isn't going to add such.
And as time goes on I expect only Samsung and LG to continue it since they sell TVs. But they may be forced to stop by Google's certification rules.
I think Lineage still includes support so if 3rd party ROM ever show up there may be options.
There are other casting apps that work (most need an app on the display too), but not as smoothly as built in Miracast. I tried a few in my Roku, but they really weren't worth the effort.

I've tried all of these "apps" most are basically a shortcut to the wireless display screen, My Razer 2 was still mirroring perfectly on Pie, but this moto? I've been able to enable the wireless display check box but every time I try to connect to either Fire Sticks/Fire TV, or a brand new NEX series head unit the phone crashes and reboots. I think after enabling the wireless display again its just a problem of screen resolution differences and rotation, looking into it. There are also a couple modules in Magisk to enable it. It crashed and bootlooped my phone and it was a pain getting it back. I do not recommend them with the G7 Power.

Moto G Stylus 2020 - USB C Power + data

I picked up a used Moto G Stylus in hopes that i could use it to run octoprint4a for my 3d printer. The issue that I'm running into is the USB C port seems to only want to allow me to either charge the phone or to control the printer. I'd very much like for it to beable to do both. I havent been able to find alot of info on the subject other than mention that some folks have been able to tweak the kernel on other android devices so that it would take power and also work as a host/data transfer. has anyone had any success with this? I'm on android 11 Os.
