# Common Services

## Media Scanner

**Media Scanner** is a background service in the **Android** system that scans media files (such as photos, music, and videos) in the device's storage and adds them to the system's **MediaStore** database, so that apps such as the gallery and music player can discover and display these files.

- Write new images or music to the **sdcard** directory via **ADB**, **OTG**, or a program, but the **Gallery** or **Music app** cannot display these files.

2. Usage

- Use the **am broadcast** command to send a scan broadcast:

```shell
#Scan a single file
adb shell am broadcast -a android.intent.action.MEDIA_SCANNER_SCAN_FILE \
    -d file:///sdcard/your_folder/your_file.jpg

#Scan an entire directory
adb shell am broadcast -a android.intent.action.MEDIA_SCANNER_SCAN_FILE \
