Problem with annatacion on android 6.0

Hi, Guys! Please, help me. On android 6 Marshmallow not found audio annatacions.
And in class Page. method "AddAnnotAttachment(String path, int icon, float[] rect)" always return false.
I will be very glad to answer! Thank you!

Can you better explain your needs please?

For the AddAnnotAttachment, a professional license is needed..are you trying using the demo project or yours? if yours, are you using the demo project's package name, so the demo license id activated.

I use the license. As the annotations I use the audio files. On 5 android works. Install applications on 6 android. Attached audio annotations are not. And I can not add an audio annotation application. "AddAnnotAttachment(String path, int icon, float[] rect)" returns false constant.
Thanks

We have tried the code below on Android 6 and it's working So, can you reproduce your issue with the demo project?
Can you send the code you are using?

If the audio file is in the SDcard (or the m_doc.setCache path is in sdcard), make sure that your app has the permission to access sdcard

And to implement the runtime permission check.
