eliza-android-system-bridge

Android library that backs the JS BridgeTransport contract declared in ../src/bridge/. Packaged inside the AOSP SystemUI replacement APK and exposes the channels listed in bridge-contract.ts over a single WebView-bound JS interface.

Responsibilities

Only this library is allowed to call AudioManager, ConnectivityManager, TelephonyManager, BatteryManager, and PowerManager. Every privileged action requires the AOSP fork to install the bridge APK as a system-signature app (/system/priv-app/ plus a matching entry in privapp-permissions-*.xml).

JS channel	Native binding
`eliza.android.wifi.state`	`ConnectivityManager.NetworkCallback` + `WifiManager.getConnectionInfo`
`eliza.android.cell.state`	`TelephonyManager.PhoneStateListener` + `LISTEN_SIGNAL_STRENGTHS`
`eliza.android.audio.state`	`AudioManager.getStreamVolume(STREAM_MUSIC)` + `STREAM_*_VOLUME_CHANGED`
`eliza.android.audio.setLevel`	`AudioManager.setStreamVolume(STREAM_MUSIC, …, 0)`
`eliza.android.audio.setMuted`	`AudioManager.adjustStreamVolume(ADJUST_MUTE / ADJUST_UNMUTE, 0)`
`eliza.android.battery.state`	sticky `Intent.ACTION_BATTERY_CHANGED` + `BatteryManager`
`eliza.android.time.state`	`Intent.ACTION_TIME_TICK` + `Calendar.getInstance().timeZone`
`eliza.android.connectivity.state`	`ConnectivityManager.registerDefaultNetworkCallback`
`eliza.android.cell.toggleAirplaneMode`	`Settings.Global.AIRPLANE_MODE_ON` write (requires `WRITE_SECURE_SETTINGS`)
`eliza.android.power.shutdown`	`PowerManager.shutdown` (requires `REBOOT` + signature)
`eliza.android.power.restart`	`PowerManager.reboot(null)`
`eliza.android.power.sleep`	`PowerManager.goToSleep` (requires `DEVICE_POWER` + signature)
`eliza.android.settings.open`	`Context.startActivity(Intent(Settings.ACTION_SETTINGS))`
`eliza.android.lockscreen.state`	`KeyguardManager.isDeviceLocked` + `KeyguardManager.isKeyguardSecure`
`eliza.android.lockscreen.dismiss`	`KeyguardManager.requestDismissKeyguard` (foreground activity context only)

Status

Skeleton only. Every method in SystemBridge.kt throws NotImplementedError. Real wiring depends on:

A signed system-app build slot in vendor/eliza/.
A matching privapp-permissions-ai.elizaos.system.bridge.xml granting REBOOT, DEVICE_POWER, WRITE_SECURE_SETTINGS, and ACCESS_NETWORK_STATE.
SELinux policy entries in vendor/eliza/sepolicy/ for the bridge service domain.

The bridge's manifest declares the dangerous permissions only. The signature-level ones above must be granted at build time through the vendor-partition allowlist; declaring them inside this library's AndroidManifest.xml is intentionally not enough.

Build
