Problems with purchase

Since December 27, 2024, Google does not allow you to buy the apps from developers registered in Russia.
There are several workarounds - please email me at nightradio@gmail.com or contact me via Telegram, and I will send you the details.


License Check Error

This error may happen during the first start or after the app update. Just try to launch the app again several times.
Also please check that...
  • Internet connection is active when you trying to launch the app.
  • There is no Lucky Patcher (or other similar APK hacking app) installed on your device.
  • You are trying to use app being logged in to same Google account you used to purchase the app.
  • You have the recent version of Google Play (Android Market) app installed.
  • "Background data" and "Auto sync" are enabled in "Accounts & Sync" settings of your device.
  • Correct date and time is set on your device.

Working with files

Basic rules

Without restrictions, the application can ONLY work with the home folder Android/data/nightradio.APPNAME/files on the internal or external memory card.
APPNAME - the name of a specific app (sunvox, pixitracker, virtualans3, etc.)
Other apps DO NOT HAVE ACCESS to this folder.
There are three ways to access this folder from the outside:
  • by connecting the device to a computer via USB;
  • via Wi-Fi export/import (in the app menu);
  • using the file manager from this discussion.
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.APPNAME
  • Documents
  • Download
  • Music (audio files only)
You can save some other formats (for example, sunvox) in Documents and Download, but then only the system file browser or the owner app (which saved these files) can read them.

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.


Camera not working (black image)

Open the Android Settings -> Apps -> APPNAME -> 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.APPNAME/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.


Other problems

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