About A2DP Volume

1. This fixes the problem some car stereos have where A2DP media streaming does not automatically connect. (option) Note: Will not initiate first device connection. * Automatically disable WIFI when device connects. * Also supports Audio Jack connections, Car Dock, Power Connection, and Home Dock as a virtual device. * Location for each device is also stored separately. * Contains widget for finding where you parked your car. * Contains a widget to initiate Bluetooth connection to A2DP sink (version 2. 13. 0.

2. * Corrects music stream (A2DP) volume when connected to Bluetooth device and restores it on disconnect. * Captures car location automatically when device disconnects. Automatic car locator. * Reads notifications while device is connected. * Automatically launch app, or shortcut when Bluetooth connects. * Automatically connect to a Bluetooth device when first device connects.

3. Auto connect another A2DP Bluetooth device after first device connects.

4. The "stored location" button will retrieve the location of the last Bluetooth device that disconnected while the service was running.

5. Read out notification messages when connected to a device in the list using audio stream and Text To Speech services (see manual for details).

6. Setting the preference "notify in foreground" and "start at boot" will ensure the service is running when needed. Android 9. 0 and up no longer need the media volume adjust feature as this is built into the OS.

7. Automatically adjusts the media volume on Bluetooth connect and resets on Bluetooth disconnect.

8. In fact, if you use the media volume adjustment feature of A2DP Volume it will fight with the volume adjust feature in the OS.

9. Pair the devices using Android network settings before using this app for Bluetooth.

10. Therefore the volume adjustment feature should not be used for Android 9. 0 and up devices.

11. Bluetooth devices must be paired to be seen by this app.
