Shizuku

Shizuku is an open-source permission management tool that grants apps elevated permissions without root, using ADB or wireless debugging.

Setup

1. Download and install Shizuku from GitHub
2. Enable Shizuku via wireless debugging or ADB
3. Open Ava, go to Settings -> Permissions -> Shizuku Authorization
4. Tap Authorize

Shizuku Status

Status	Description
Authorized	Shizuku is running and Ava has access
Waiting for authorization	Shizuku is running, tap Authorize
Not running	Start Shizuku first
Not installed	Download and install Shizuku

What Shizuku Enables

• Screen brightness control
• Display resolution adjustment
• Screen orientation lock
• Intent execution
• Other system-level operations

Note: Shizuku requires Android 7.0 (API 23) or higher. On Android 5-6, the Shizuku card is auto-hidden.

Root

Root access provides the most stable operation for 24/7 panel use.

Root Status

Check root status in Settings -> Permissions -> Root Status:

• Granted: Root access available
• Not granted: Root not available or not granted

What Root Enables

• Better background protection
• Boot scripts
• Screen control (lock/unlock)
• Reboot device
• Stable Bluetooth proxy on low-end devices
• Automatic permission handling for mods (e.g., Meta Portal Support)

Recommended for

• Wall-mounted panels running 24/7
• Devices with aggressive battery optimization (MIUI, EMUI, ColorOS)
• Bluetooth proxy on low-end BLE chips (compatibility mode)
• Facebook Portal devices with Meta Portal Support mod

---

Device Admin

Device Admin allows Ava to lock the screen without root.

Setup

1. Go to Settings -> Permissions
2. Find Device Admin
3. Tap to enable
4. Confirm in system dialog

What Device Admin Enables

• Lock screen control from Home Assistant
• Screen lock entity in HA

Note: On some devices (e.g., Facebook Portal), Device Admin cannot be granted through the UI. Use ADB-assisted permission paths instead.

---

ADB Permission Grants

For devices where the system UI fails to grant permissions normally (Android 8 and below, Facebook Portal, etc.):

GeckoView Engine Package

adb shell appops set com.example.ava.gecko SYSTEM_ALERT_WINDOW allow
adb shell settings put system kill_background_services_list "com.example.ava,com.example.ava.gecko"

Meta Portal Support

Use the provision.sh script:

cd ~/Downloads
chmod +x provision.sh
adb devices
./provision.sh com.example.ava

See Mod Store for Meta Portal Support details.
