Hi @KonstaT ,

Thanks for the ROM, it is great, how ever, how can I disable app drawer button to goes completely full screen?
I have already switched to Gesture navigation.

I did search the setting, but could not find one => Found it "System => Button:"

Thanks for the help.

Thanks for your work!

1. Maybe it's a lame question, but what about Netflix? Can it run with at least in 1080p?
2. I don't have atm any wireless remote/mouse/etc. Is there any app for my phone that I can use to navigate in the menus/apps on the Android/AndroidTV roms?

1. Due to Widevine L3 video playback is capped at standard definition on apps that provide DRM protected content.

2. You need input device of some sort of course. Mouse/keyboard/touchscreen on regular tablet UI Android builds - remote (USB remote, Bluetooth remote, IR remote, TV's remote using HDMI-CEC, arrow keys on your keyboard, etc) on Android TV. Google TV remote app (https://www.androidpolice.com/2021/09/27/hands-on-how-to-android-tv-new-remote/) might work on regions where Google TV is available and depending on the gapps you've install (I'm not aware of there currently being any Android TV 13 gapps). I haven't tested any third party remote applications but there seems to more than few.

I am an avid user of the Android app Tasker and it would be awesome if you and Joao (Tasker dev) got together and found a way for Tasker to use GPIO pins as contexts or outputs.

One of the issues listed is

• SELinux is in permissive mode

I have an issue with my Google Chromecast with Google TV as it runs Android 10 which introduced a SELinux policy to stop the Android 'sendevent' command from working. Why do I need that? I'm integrating the stick into home assistant home automation

Android TV

Instructions on how to integrate Android TV and Fire TV devices into Home Assistant.

www.home-assistant.io

and the default 'input' command (for an on-screen remote) is super slow... Worked with Android 9 but there's no way for me to go back to 9.

So if the above issue means SELinux is not 'active' and is not enforcing policies this could be a good thing and work for me using one of my Pi 4

What do you think?

I'm not a Tasker user so I'm not exactly sure what you mean by "contexts or outputs". AFAIK you can make Tasker execute shell scripts that you can use to control the GPIO.

Very possible but that's something you need to test yourself.

You can also install LineageOS on Google Chromecast with Google TV (https://wiki.oddsolutions.us/devices/sabrina/) and set SELinux permissive since you can also have root access.

how can i add support for a 4g lte modem from waveshare? I just need the internet access and gps, no sms or phone

@KonstaT

You can't without building Android from source and adding the necessary support for the hardware. If you want to build AOSP (or something AOSP-based) for Raspberry Pi, you can look into the Raspberry Vanilla source code (https://github.com/raspberry-vanilla) I've recently released.

My builds are configured as wifi only tablet so they don't even have Android telephony framework or drivers to support any modem hardware. I have builds (of older Android versions) that have support for Sixfab modem HAT and Quectel EC25. LTE data and SMS works fine. It's also possible to make/receive calls but in-call audio is not working. It's not something that I plan to include in public releases as practically no one has the hardware.

Oh yeah, i totally forgot the official atv remote. Guess it's not working with the tablet version of the rom.

So, right now i'm downloading the 19.1 version, since the 20 isn't available with your link. Is there an other mirror for it that i can't find?

Edit: download links are working now

 

[mavru]

Can't find GApps-13.0-arm64-ATV-xxxxxxxx.zip mentioned in LineageOS 20 Android blog.
Also links in this post lead to OS 19 but OS 20 is mentioned:

Can you please tell where to dl aforementioned Gapps for OS 20 if they exist?

There are no Android TV 13 GApps at the moment, flashing the 12 version is not working.

My question about that for the dev:
Can i use the atv13 ota zip to upgrade the atv12 rom with gapps to use the google services?

No, it's only for Android TV.

I added AndroidFileHost links as that seems to be working again (they've had tons of issues last couple weeks). This seems to generate enough traffic to get blocked on Google Drive every other day so that's not ideal either.

I'm not aware that there is any Android TV 13 gapps packages available at the moment. There is for the regular tablet UI Android 13, though, which is also linked in the FAQ. I don't have anything to do with any gapps release so this is something you would need to ask where you generally get your gapps.

No, you need gapps for the right Android version in any case.

Updating 19->20 is not possible due to reasons stated in http://disq.us/p/2ru05g7

Greetings! I have a Raspberry Pi 400 and always wanted to run Android on it. After seeing a headline on a news site this week about this thread and Android 13 becoming available, I was delighted.

However, the instructions warn that it’s for advanced users only, which I am not. My main use for this would be IPTV and a handful of Android TV based streaming apps amongst various other APKs. Not working mentions hardware video decoding, does this mean something like TiviMate would not be working? Just trying to determine if a novice user like myself would be able to use this reliably

thank you!

edit - it seems I am late to the party and Android has been installable even previous to this, on a Raspberry Pi 400? Is that correct? If so, is there a reliable version you recommend that has a working Google Play store? I don’t mind earlier Android TV versions if needed! Thanks again

Thanks, hadn't even noticed that this had made into XDA news!

Lack of hardware video decoding/encoding means that Pi's dedicated hardware for H.264/H.265 video dec/enc is not used but this is done on the CPU with software video dec/enc instead (some explanation here https://forum.xda-developers.com/t/...3-for-raspberry-pi-4-b.4481977/#post-87316981). Software video decoder normally manages to keep up 1080p30 videos just fine. This also depends on the video codec that is used. Some services (e.g. Youtube) have switched to using VP9 for which Pi doesn't even have hardware dec/enc to begin with. There's also some limitations with streaming services that provide DRM protected content (e.g. Netflix) due to Widevine L3, but that's another story. I don't see any specific reason the app mentioned wouldn't work but that's something you need to test yourself.

UI on all the Android TV releases looks pretty much the same. You probably don't even know what Android version you're running unless you go specifically looking for it in the settings. There could be some issues with HDMI audio on Android 12/13 builds that is not an issue on Android 11 (see e.g. http://disq.us/p/2r2wh1w). There's currently no GApps available Android TV 13, for Android TV 12 you only have MindTheGapps, as for Android TV 11 there's also option to use OpenGApps which gives you the Google's Android TV launcher as well. Choice is entirely your of course and GApps are not part of my releases in any case. You can see the list of all the available builds here (https://konstakang.com/devices/rpi4/).

Is it me or is there no place to download your copy of TWRP for this?
