Android User Guide

This page summarizes common operations after the X3568 Android system boots, including serial console, audio/video, WIFI/BT, external storage mounting, camera, Ethernet, HDMI, power control, and suspend / wake-up.

Command Terminal​

Connect the serial cable to the debug UART of the mainboard. After Android starts, the system terminal log can be viewed through the serial console.

Play MP3​

Make sure the external SD card or USB disk contains MP3 files. Open the music player, and the system will automatically scan audio files. Tap a file to play it.

Play Video​

The Android Gallery scans supported video and image files on external storage. Tap a video file with the play icon to start playback.

Use WIFI for Network Access​

The X3568 mainboard has an on-board WIFI/BT combo module, so an additional USB WIFI module is not required. Go to Network & Internet, enable Wi-Fi, select the target network, and enter the password.

Transfer Data by Bluetooth​

Go to Connected devices -> Bluetooth, enable Bluetooth, and search for devices. After pairing with a phone or another Bluetooth device, files can be shared through Gallery or File Manager.

Play Music by Bluetooth​

Prepare a Bluetooth speaker and switch it to Bluetooth mode. Pair it in the board's Bluetooth settings. After pairing, audio/video playback will output sound through the Bluetooth speaker.

Use USB Mouse and Keyboard​

After the board starts, connect a USB mouse, keyboard, or wireless receiver to the USB HOST port to operate the Android UI.

Mount TF Card​

After system startup, the TF card is automatically mounted under /storage/, and the mount point is identified by UUID.

Mount USB Disk​

After inserting a USB disk, the system automatically mounts it under /storage. Use ls /storage to check the mount directory.

Camera Capture​

Open the Camera application to enter preview mode. Tap the capture button to take photos, and switch between photo and video modes from the UI.

Wired Ethernet​

Connect a valid network cable to the Ethernet port. After the port LED blinks normally, the board can access the network through wired Ethernet.

Infrared Remote Control​

The X3568 hardware supports infrared remote control by default. It can be used to operate the Android UI and is suitable for set-top-box scenarios.

HDMI Display​

HDMI can mirror the LCD video to an HDMI TV or monitor. It supports 1080P / 2K HD video and audio transmission.

Power On / Off​

The X3568 uses the PMU for power management. After a 12V power adapter is connected, the board powers on automatically. In Android, long-pressing the power key opens the shutdown confirmation dialog.

Suspend / Wake-up​

After entering Android, short-press the power key to turn off the display and enter suspend. Short-press the power key again to wake the board.
