A systemless and standalone application which let's you skip tracks on your Android 8.0+ device by long pressing the volume keys.
Working on every 8.0+ ROM, including stock AOSP without root. Tested on 8, 9 and Q Beta!
Download the newest release from the link below and install it on your device as usual.
Connect your device to a computer and enable developer settings and fire up
adb shell pm grant com.cilenco.skiptrack android.permission.SET_VOLUME_KEY_LONG_PRESS_LISTENER
On startup the app will check if has the permission. If you don't see any message the process worked and you are ready to go.
If the app is installed as system application by flashing it through a recovery this step is not needed as the permission is granted automatically.
Please feel free to send me issues and pull requests for improvements, stability and new feature ideas.
