Android User Guide

The Android manual covers terminal access, MP3 playback, video playback, Wi-Fi, Bluetooth, USB mouse and keyboard, TF card, USB disk, screen rotation, Camera, wired Ethernet, remote control, HDMI, power on/off, and suspend / wake-up.

Terminal​

Connect the debug UART. After Android boots, it enters the Android terminal automatically. Useful commands:

cat /proc/cpuinfo
cat /proc/meminfo
cat /proc/partitions
cat /proc/version
ifconfig
dmesg

MP3 Playback​

Place MP3 files on the external SD card. Open the music player; the system detects audio files automatically and plays the selected file.

Video Playback​

Android provides video playback through Gallery. Gallery scans the external SD card for recognizable video and image files. Items with a play icon are videos; items without it are images.

Wi-Fi​

X8385 has an on-board Wi-Fi / BT combo module, so no extra USB Wi-Fi is needed.

Settings -> Network & Internet -> Wi-Fi

Turn on Wi-Fi, select the wireless network, enter the password, and connect.

Bluetooth File Transfer​

Settings -> Connected devices -> Bluetooth

Turn on Bluetooth, search for devices, select a target device, and pair. After pairing, images can be sent from Gallery through Bluetooth sharing.

Bluetooth Audio​

Prepare a Bluetooth speaker and switch it to Bluetooth mode. Search and connect it from the board Bluetooth page. After connection, audio/video playback uses the Bluetooth speaker.

USB Mouse and Keyboard​

Connect a USB mouse, keyboard, or wireless mouse/keyboard receiver to the USB HOST port to operate the Android UI.

TF Card and USB Disk​

Mounted TF cards and USB disks can be checked under /storage.

ls /storage
mount
df -h

Screen Rotation​

Screen rotation requires both Android display direction and touch coordinate direction to be checked. Reboot and verify after modification.

Camera, Ethernet, and HDMI​

  • Camera: check MIPI CSI Camera connection, power, reset, and Android Camera app.
  • Ethernet: X8385 uses a USB-to-100M Ethernet interface.
  • HDMI: the standard HDMI connector is used for external display.
