[Bug] "App not installed" error on Android TV Box (TOX3 / Amlogic S905X4)

[lalik77]

Device Information

• Device: TOX3 TV Box (by Ugoos)
• Chipset: Amlogic S905X4 (Quad-core ARM Cortex-A55, 64-bit)
• RAM / Storage: 4GB / 32GB
• Android version: Android 11
• Interface: Android TV (not standard Android)

Problem Description

Cannot install NekoBox on Android TV Box.
All APK variants result in "App not installed" error during installation.

Tried APK variants

• arm64-v8a — "App not installed" (tested versions: 1.4.2, 1.4.1, 1.4.0)
• armeabi-v7a — after multiple attempts it installed successfully (see video),
  but this is a 32-bit build and does not match my 64-bit processor (ARM Cortex-A55)

2026-04-19.11.19.46.mp4

Expected behavior

arm64-v8a APK should install correctly on a 64-bit ARM device running Android 11

Steps to reproduce

1. Download APK from official GitHub releases page
2. Transfer APK to device via USB flash drive
3. Open APK via file manager
4. Tap "Install"
5. Status bar -> not finsihed
6. Error: "App not installed"

Notes

• Unknown sources (sideloading) is enabled in device settings
• No previous version of NekoBox was installed
• Tried multiple file managers for installation
• Issue seems related to Android TV environment incompatibility

Request

Is there a plan to support Android TV boxes?
Or is there a workaround to install NekoBox on Android TV?
