IDK, I haven't got the hardware so I haven't looked into it. That's something that you need to figure out yourself if you want to have it working.

Have you tried configuring config.txt following the documentation (https://www.hifiberry.com/build/documentation/configuring-linux-3-18-x/)? Check dmesg that the device is registered after adding the required overlays in config.txt. If it uses ALSA device 0 it might work with no modifications to Android audio HAL.

Hey @KonstaT I'm having some new troubles with the build. After 10-30 days that I use it without any problems, it starts freezing. It boots fine but it slow down quickly and freezes completely after few minutes, adb still connects and I can see the logcat but commands don't work, and then I've to flash it again to get it back working fine.

I don't have a clue of where to start to debug this problem, I'll be glad if you can point in the right


These are some lines of the logcat of a freezed one:

Here’s my build of LineageOS 14.1 for Raspberry Pi 3 Model B. It is unofficial and unsupported by the LineageOS team. It’s for advanced users only.

Is it possible to do USB accessory mode instead of USB host mode on this ROM?

Sorry, not quite sure what you're asking here. What do you need USB accessory mode for?

USB doesn't work here quite like on other Android devices.

你好 請問 使用藍牙配對藍牙揚聲器 可以成功配對但是沒有音頻輸出 該怎麼解決 謝謝
Hello Q. Pairing Bluetooth speakers with Bluetooth can be successfully paired but there is no audio output. How to solve it Thank you

This build doesn't support bluetooth A2DP. Added the support in LineageOS 15.1. Both of these builds are now discontinued.

Please update to using my LineageOS 16.0 build instead. It's much more up to date, bluetooth A2DP works, and it works much better than previous versions anyway.

Is it possible to create an external storage partition for this ROM? Such that getExternalStorageDirectory() function would return something meaningful? I have an app that absolutely requires it...

This build uses emulated internal storage (/data/media) as Android's 'sdcard'. Technically it's possible to create any physical partitions on the actual sdcard and add corresponding storage configuration (https://source.android.com/devices/storage/config-example). You'd need to compile the ROM from source with your changes of course (https://github.com/lineage-rpi/android_local_manifest/tree/cm-14.1).

Google had a bad habit of changing how sdcards are handled in Android with pretty much every new Android version at one point. Even a quick Google search couldn't tell me what path getExternalStorageDirectory() should return other that it's deprecated in recent Android versions. Many app developers didn't bother to keep up with the API changes either so I'd assume it's some issue with your app. Generally when referring to 'external storage' in Android means the primary sdcard which is internal storage on this device. To add to confusion this is the only device that boots from an actual external physical sdcard...

i have wifi internet connection
wanna make a wlan0 to eth0 internet share, is it possible with LineageOS 14.1 - KonstaKANG (Android 7.1.2)?
need a dhcp server, ip_forward,...
like here, but cant use this guide at android system

I doubt there's any easy way to achieve that on Android.

 

[uragan1987]

sounds not good

 

[uragan1987]

KonstaT do you know how to enable USB-Tethering at rpi?

 

[KonstaT]

There's no easy way to do that either. You can only share the ethernet connection using wifi tethering.

How to install:

1. Follow the official Raspberry Pi instructions for writing the image to the SD card (Linux, Mac, Windows).

FAQ:

Q: I can’t find developer options, why?
A: Settings -> About phone -> Click ‘Build number’ several times

Q: I don’t have reboot options in power menu, why?
A: Settings -> Developer options -> Advanced restart

Q: I have no root, why? What is that hashtag on my status bar?
A: You need enable root access under Settings -> Developer options -> Root access. Root management is now integrated as part of LineageOS’ Privacy Guard and you can manage per app permissions under Settings -> Developer options -> Manage root access. You’ll have a persistent notification in the status bar when you’re running an app that uses root permissions.

Q: I have official 7” LCD display and touchscreen. What should I do?
A: Execute following commands in ‘adb shell’/serial console/terminal (you can enable built-in terminal app from Settings -> Developer options -> Local terminal) and reboot your device:

su
rpi3-display.sh

Q: Settings -> Storage shows xx GB used by system. There’s unallocated space on my sdcard. What should I do?
A: This is a 4 GB image, remaining space on your sdcard will remain unallocated. Settings app shows unallocated space as used by system which in reality it is not. You can use e.g. GParted and extend /data partition (/dev/block/mmcblk0p3) to cover the unallocated space. Resizing the partition manually will break support for encrypting /data. Format /data in TWRP recovery (Wipe->Format data) after resizing to leave required space for crypto footer.

Q: Raspberry Pi doesn’t have power button, how do I power off/reboot my device?
A: Following keyboard keys work as Android buttons: F1 = Home, F2 = Back, F3 = Multi-tasking, F4 = Menu, F5 = Power, F11 = Volume down, and F12 = Volume up. You can also use one of many third party reboot applications.

Q: How to boot to TWRP recovery?
A: There’s currently no proper way to boot between Android and TWRP, but this can achieved by renaming the ramdisk you want to boot. Execute following commands in ‘adb shell’/serial console/terminal (you can enable built-in terminal app from Settings -> Developer options -> Local terminal) and reboot your device:

su
rpi3-recovery.sh

If mouse cursor doesn’t appear, try replugging your mouse.

Q: How to boot out of TWRP recovery?
A: Flash my recovery2boot zip in TWRP.

Q: How to install Google apps?

1. Download open_gapps-arm-7.1-pico-xxxxxxxx.zip and save it to your device’s internal storage or use an external USB drive
2. Boot to TWRP recovery (see FAQ)
3. Install open_gapps-arm-7.1-pico-xxxxxxxx.zip from your selected storage
4. Wipe->Factory reset!
5. Boot out of recovery (see FAQ)

recovery2boot Download link is not working, it's showing "no mirrors found."
please share the zip file.

This build is seriously outdated and it's been discontinued for years. You really shouldn't be using this for anything! Use the latest LineageOS 16.0 (https://xdaforums.com/raspberry-pi/orig-development/dev-lineageos-16-0-android-9-raspberry-t3943678) or 17.1 (https://xdaforums.com/raspberry-pi/orig-development/dev-lineageos-17-1-android-10-raspberry-t4139051) build instead.
