Camera not working (black image)

Open the Android Settings -> Apps -> APPLICATION_NAME -> turn on all permissions.
If still not working: reboot your device.

Screen is black or flickering

1) Open the primary shared storage of your device (most often it is the internal memory, not the external SD card).
2) Go to the following directory: Android/data/nightradio.APPLICATION_NAME/files (where you will see all the files of the app).
3) Put this file to the directory described above;
4) Try to launch the app again.

Can't load/save files

Basic rules

Without restrictions, the application can ONLY work with the home folder Android/data/nightradio.APPLICATION_NAME on the internal or external memory card.
APPLICATION_NAME - the name of a specific app (sunvox, pixitracker, virtualans3, etc.)
Other apps (except file managers) DO NOT HAVE ACCESS to this folder.

Below are a few additional folders where you can save files so that other apps can read them. But these files can ONLY be in well-known audio/graphic formats such as WAV, MP3, OGG, FLAC, JPG, PNG.
  • Android/media/nightradio.APPLICATION_NAME
  • Documents
  • Download
  • Music (audio files only)
If there are no files visible in the folder, open the app settings (via Android settings), and then reset and re-enable all its permissions.

Accessing files within the app

The app file manager has several navigation buttons:
  • button with a house - go to the home folder on the internal memory card;
  • CARD2 (with a picture of a memory card) - go to the home folder on the external memory card;
  • ".." - go to a higher level (to the parent directory); press this button several times if you need to reach a folder at a different level.
The internal card is the main file storage of the device.
External card - additional storage, usually in the form of an SD card.

Accessing files from outside

Use the Files app or connect the device to your computer via USB.
Not all file managers have access to Android/data. Please see this discussion for a description of the different ways and file managers.

Other problems

1) Open the primary shared storage of your device (most often it is the internal memory, not the external SD card).

3) Find the log file called APPLICATION_NAME_log.txt.
4) Send it to me and describe the problem.
