Using ScreenView

ScreenView is used to view and control the primary screen from an external display. To use it, open the app on an external display.

Remote Control via the Intent Interface

ScreenView features a remote configuration interface by means of Intents. This allows changing some settings from other apps or ADB.

Enable/Disable Input: With ADB:

adb shell am start \
  -n com.example.screenoverlay/.MainActivity \
  --es pref_key "use_input" \
  --ez pref_value <true or false>

Or programatically:

val intent = Intent().apply {
    component = ComponentName("com.example.screenoverlay", "com.example.screenoverlay.MainActivity")
    putExtra("pref_key", "use_input")
    putExtra("pref_value", true)
    addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)  // required if outside an Activity
}

context.startActivity(intent)
