Android Question MEDIA_BUTTON with Android 7+ and API 26

[Pendrush]

Hi all,
I have tried every example on forum including all examples from:
https://www.b4x.com/android/forum/threads/android-intent-action-media_button-again.48890/#content
also tried to change manifest from example provided by google from:
https://developer.android.com/reference/android/support/v4/media/session/MediaButtonReceiver.html
Without success with BroadcastReceiver library.
I'm unable to fire event in service when media button on headphones is clicked.
Tested on two devices: Nexus 5 with LineageOS (Android 7.1.2) and Samsung Note 5 (Stock Android 7.0.0).
My app have minSdkVersion set to 21 and targetSdkVersion set to 26.

Can anyone provide some working example?

This is a problematic feature. If you find a Java code that is not implemented in one of the related threads then I can help you port it.
