    When running my app in release mode I get this error message: /mnt/sdcard/AMF/test.txt: open failed: EACCES (Permission denied)

    The Folder and file exists. If I rund this small app in debug mode, I do not get this error. How funny!?

    I know that Google has changed acceess rights when writing to external card but this is the internal card.
    When I open ES file Explorer I can create and delte files in this Directory

    Can someone please help!!!!!

    Don't hardcode to path to the "sdcard". It will be different on other devices.

    Use File.DirRootExternal. As a bonus it will add the required permission for you.
    thedesolatesoul and DonManfred like this.

    My app works fine using this approach.
    I seems that "File.DirRootExternal" is a part of the internal memory card which is emulated as being an
    external Card. Right?

    As @Erel already stated: the Path to the REAL External SdCard can differ from model to model.
    If you are using Android 5+ then you can use this library to find out the path to the (2nd) external SdCard. There is a codesnippet in the forum to find all paths. Probably your External Sd too.
