Miscellaneous and Keep Alive

The Miscellaneous card in Settings provides tools to keep Dioxamine connections alive and active in the background when the app is minimized.

Keep Alive Background Service

By default, modern Android versions (Android 11+) apply aggressive background limits, including the Cached Apps Freezer and Doze Mode. If an app is minimized without a Foreground Service, the operating system pauses CPU execution, freezing active ADB TCP/USB sockets and fastboot operations.

The Keep Alive feature resolves this by running a dedicated Android Foreground Service with a WakeLock.

Enabling Keep Alive

  1. Open the Settings tab.
  2. Tap the Miscellaneous expandable card.
  3. Toggle on Keep Alive.
  4. Grant the requested system permissions:
    • Notification Permission (POST_NOTIFICATIONS on Android 13+ / API 33+): Required to show the persistent foreground service notification.
    • Battery Optimization Exemption (Android 6.0+ / API 23+): Prompts you to exempt Dioxamine from battery optimizations to prevent Doze mode from sleeping background network/USB transfers.

Live Status Notification

While Keep Alive is running, Dioxamine displays an ongoing notification in your notification shade showing real-time connected device metrics:

  • Both ADB and Fastboot connected: e.g., 1 ADB device connected, 1 Fastboot device connected
  • ADB Only: e.g., 1 ADB device connected or 2 ADB devices connected
  • Fastboot Only: e.g., 1 Fastboot device connected
  • No devices connected: No devices connected • Active in background

Notification Actions

  • Tap Notification: Instantly brings Dioxamine back to the foreground.
  • Stop Action: Tap the Stop button directly on the notification to terminate the background service and release the WakeLock without needing to navigate to the Settings tab.
