Запуск сканера медиа на устройстве с одним щелчком мыши
This application runs the Media Scanner on your device to re-scan the external storage for music, videos, and pictures. It fixes problems where applications such as music players are unable to find files transferred to the device via adb, for example.
Unlike other media scanner launchers, this application is very easy to use. Simply tap the application icon and your transferred files should be discovered in a few moments.
