[DEV][ROM][UNOFFICIAL] LineageOS 17.1 (Android 10) for Raspberry Pi 4 B

[KonstaT]

Is there any way that I can add my non-nexus Bluetooth tv remote for control? Specifically MI TV Remote.

Why not? Use Settings -> Remotes & Accessories to pair.

The official remote app works great including voice commands so I'd probably recommend using that.

The rom works pretty well now that official android remote control app. Great Work!
I wanna suggest 2 app very usefull:
1. Terminal shortcut very usefull to write 1 time only all terminal scripts.
2. Tv app Repo to show sideloaded apps into the stock launcher.

1. There's really no need for a "normal user" to run any scripts with the latest build anymore. Booting into/out of TWRP is handled from system menus.
2. Not quite sure what you mean with this. Which "stock launcher"? One before or after installing gapps? I think the gapps Android TV launcher only displays icons for actual Android TV compatible apps. Edit. Apparently Tv App Repo is an app. No, there's no need to include third party apps you can install yourself.

Yeah, the first one thing is to run scripts to switch from HDMI to JACK, i use your Rom sometimes with an HDMI tv, sometimes with a HDMI->DVI adapter, so i need to use audio from jack (or now the rom self understand what device to use?
The second thing is to put on google launcher (yes ive installed gapps) all not officially compatible sideloaded apps.
Mine suggestions wasn't intended to add these apps on your rom sure, only to give some useful tips to automate some little things

With the regular Android build you can do things like this from the new device settings menu (Settings -> System -> Advanced settings) without running any scripts. Android TV doesn't have hooks for the device settings apps but I'll look into if it can be launched from the setting somehow (manually with 'am start -n org.lineageos.settings.device/.RaspberryPreferenceActivity' works at least). It doesn't have an Android TV friendly UI and I'm really not interested in making a Leanback version. I don't think average user need to switch between audio devices that often either (most likely you only do it once).

Tv App Repo is an app. I tested it and didn't manage to get it to do anything useful. It's been last updated in 2017. There's no point to include third party apps you can just install yourself.

New Android TV build.
https://konstakang.com/devices/rpi4/LineageOS17.1-ATV/

-initial device settings for various Raspberry Pi specific options (Settings -> Device Preferences -> Raspberry Pi settings)
---audio device option (HDMI/3.5mm jack/audio DAC)
---display options (graphics drivers, display resolution, display rotation)
---options for IR remote, hardware keys, CPU overclock, SSH, and RTC
-fix wifi & bluetooth on Pi 400, should be fully functional now (Compute Module 4 support still untested)
-support using HDMI:1 (fix HDMI audio in Android & fix display in TWRP)
-fix touch input on Fondar USB touchscreen (thanks to maxwen)
-update to Linux 5.4.77 kernel and patch known vulnerabilities (CVE-xxxx-xxxx, and more)

 

[KonstaT]

New build. This has been now tested by quite a few people and it should be fully functional on Pi 400 as well.
https://konstakang.com/devices/rpi4/LineageOS17.1/

-device settings improvements
---fix audio device option
---add CPU overclock option (make sure to take care of cooling if you decide to overclock!)
---add SSH option and improve support for built-in SSH server (see FAQ)
-fix wifi & bluetooth on Pi 400, should be fully functional now (Compute Module 4 support still untested)
-support using HDMI:1 (fix HDMI audio in Android & fix display in TWRP)
-fix touch input on Fondar USB touchscreen (thanks to maxwen)
-update to Linux 5.4.77 kernel and patch known vulnerabilities (CVE-xxxx-xxxx, and more)

Just update to the latest version as I was on one of the earlier ones. Everthing feels better but how do I get things like live wallpapers to work. They did only the earlier version I was on but all I get is either a black screen or a message saying this video can not play

Things are going pretty smoothly if something like live wallpapers is the main concern.

What was the previous build you were using? Logcat?

Am not complaining and infact think it runs so much better it's. I was asking because I have it setup in my kitchen on a touchscreen display for everyone to use and the live wallpaper looked better. Sorry I can't remember which version it was on as it as been on it for a while

Thank you for your great work. Everything is working well, except the HDMI-audio when using bluetooth. Like in the the previous versions the audio is stuttering, no matter which bluetooth-device I use. Sometimes also the normal audio-output begins stuttering after a while. When I turn on bluetooth in that cases the stuttering in bluetooth-headset is gone. Weird behaviour! Do you have an idea how to fix that?

 

[福山雅治]

Thank you for your great work!
The extensibility of being able to attach various accessories, such as an earphone jack, I find great appeal.

I didn't take it as a complaint (more of a compliment really ). There's just been a lot bigger issues to deal with to get where we are with Android on Raspberry Pi today.

Was it even a LineageOS 17.1 build? LineageOS 16.0 still used different graphics drivers (see FAQ on how to switch to SwiftShader on LineageOS 17.1).

There's been several issue reports of bluetooth audio stuttering after installing gapps. I don't think anyone has mentioned that it's HDMI audio that's stuttering! I have though that it's an issue with bluetooth audio and wondered why I haven't been able to reproduce it with my bluetooth speaker/headset. Though, I think some of them do actually mean bluetooth audio.

Either way, I don't think I've seen any proper logs yet (logcat?).

Would it be possible to make a USB ir remote receiver work with android tv? A build of Android tv x86 works on an older Dell latitude e5420, maybe if I find the keymap file on android x86 and copy it to the pie it'll work? Since they are both Linux based (libreelec on the pi works with the remote as well as hdmi cec) it's an old remote from the windows xp media center edition back in 2005. Thx! And it's working great Netflix, Hulu and Amazon prime video works as well as other apps

Think I'll leave it as it is mate, it's running great as it is and knowing my luck I'll change somthing and blow the whole street up. Everyone can just live with a still image....:laugh:

Also I noticed the recent apps is broke u can't close the running apps on the android tv latest build

Not sure what you mean with USB IR remote receiver here. Why not just simply give it try? Depends on what type of device it appears as ('dmesg' pluggin it in?). I'm not supporting LIRC here (gpio-ir driver is used for GPIO IR receiver instead).

I have an USB air mouse/remote/keyboard/whatever combo that AFAICT uses IR between the remote and receiver and it works just fine.

Also I noticed the recent apps is broke u can't close the running apps on the android tv latest build

It's not broken. Android TV simply doesn't have a recent apps view. It's a dumbed down version of Android. For some reason the LineageOS 16.0 version still has it but this has been the case for regular Android TV devices for many Android versions.

You can close individual apps from the settings menu. There's also a development setting option not to keep activities which closes apps as you exit them.

Bluetooth A2DP sink / HSP

Hi,

Brilliant work. I am looking to make a car system with this, for which i would need a headset / a2dp sink bluetooth set up. Is this possible?

Cheers,
Steve

i just came across a flirc usb ir receiver which allows you to control a computer or media device in this case the pi with a remote control. you plug it in the pc and program the remote control keys from the remote which it receives. When Flirc receives Infrared (IR) signals from a remote control (e.g. a TV remote control) it then sends a keypress (as if it were a USB keyboard and you were pressing a key). so that will defiantly work! only 20 on amazon

Not out-of-the-box at least. I would need to compile the bluetooth app with some additional features enabled (https://github.com/LineageOS/androi...h/blob/lineage-17.1/res/values/config.xml#L17). There's no guarantees it would actually work even after that.
