So, I wanted to replace one of my Dahua VTHs with a wall-mounted Home Assistant tablet (the Nexus 7 2012 grouper). Before I installed anything, I rooted the device and installed LineageOS 15.1 (Android 8.1 Oreo), and the tablet became wayyyy smother and more usable. Unfortunately, because of only 87MB left in the system partition, I couldn’t get Gapps to work, even the stripped-down version.
Anyway, I saw that Fully Kiosk and the HA Companion app were available as APKs. But after installing them and opening the apps, both didn’t launch. I then tried the HA Minimal app, which doesn’t rely on Google Play Services, but that also didn’t work.
In this case, I don’t know what’s going on with all this. Android 8.1 is supported on both Fully Kiosk and the HA Companion App. Maybe it’s something to do with the Nexus 7 being 32-bit?
Fully kiosk is working now because I reverted to version 1.36, which doesn’t require Google Play services. But still, the HA app doesn’t work, even if it is the minimal version.
You’ll need to resize the system partition in order to get gapps to install correctly.
The bare minimum you need is Google Play Services as Android apps rely on it, otherwise you’ll get force closes and frequent crashes even with sideloaded apps.
The guide you’re we’re following is really outdated and unreliable. Instead, install the unofficial LineageOS 20 rom by followmsi on XDA step by step. It is based on Android 13, and includes the repartition script which you can flash using a custom recovery (twrp).
That guide is for the 2013 tablet, which is a different product entirely. On the 2012 Nexus 7 you are better off using something in a web browser or trying out postmarketOS which is Linux based, although that is lacking 3d graphics support
Thread is 2 years old, I mistakenly linked the wrong rom, my bad.
Anyhow, if for some reason you’re still rocking a 13-year-old tablet, you’re asking for trouble. No matter what ROM/app you use, it’s a piece of trash now.
oops I thought it said 2025, apologies. But yes it isn’t an ideal tablet, but its much more powerful than the ones I’m seeing on sites like Aliexpress being advertised for use with Home Assistant! I plan on using one of my many Nexus 7s in my room as a project
