Egepa New Member Sep 29, 2024 #1 Hello everyone, I am experiencing a similar bug to this post https://www.b4x.com/android/forum/t...ect-my-usb-accessory-before-opening-it.30222/, when i try to call InputStream.close() on my apps onDestroy() it does throw "read interrupted" exception fine. However when i re-open my app and try to get info from inputstream i can't get anything even tough outputstream works fine (I can send data). I do close filedescriptor, inputstream, outputstream, and exit the thread doing the reading. What can it be the problem i have been looking for answers online for days but only answers i found was related to do "soft reset". When i unplug and replug the usb cable it works fine again until i exit and enter again to the app. Is there something i am missing, does anyone solved a simillar problem?
