An experimental demo for capturing and displaying screenshot of Android devices.

Required configuration to run it wirelessly :

• Get your device IP address (in Settings - System - About phone - Status) e.g : 192.168.x.x
• Enable adb over TCP/IP on your device: adb tcpip 5555
• Connect to your device: adb connect 192.168.x.x:5555 (replace 192.168.x.x with the actual IP address)
• Unplug your device
• Go through all the steps under Common usage

To switch back to USB mode: adb usb.

Common usage:

Note:

For the "Unix-like" OS, once apk file installed, you can use the cmd_tool to automate the following adb related operations.

• Install the apk properly on the phone (Don't install it via Run 'app' from Android Studio).

./gradlew clean installDebug

• Push the apk to the tmp folder

adb push ${your-project-path}/DroidCast/app/build/outputs/apk/debug/DroidCast-debug-1.0.apk /data/local/tmp

• Start our internal server process for image processing by app_process

$ adb shell
D1C:/ $ export CLASSPATH=/data/local/tmp/DroidCast-debug-1.0.apk
D1C:/ $ exec app_process /system/bin com.rayworks.droidcast.Main '$@'
>>> DroidCast main entry

• Please note: On some devices, if you got the error "appproc: ERROR: could not find class 'com.rayworks.droidcast.Main', please replace the above value of CLASSPATH with the result returned by adb shell pm path com.rayworks.droidcast.

• Use adb forward socket connection from your pc to the connected device

$ adb forward tcp:53516 tcp:53516

• View the image via web browser http://localhost:53516/screenshot.jpg or with the specific dimension e.g. http://localhost:53516/screenshot.jpg?width=1080&height=1920
