Use adb to hide virtual keys and status bar of android devices

ADB (Android Debug Bridge) commands allow you to perform a variety of actions on a connected Android device, including controlling the display and hiding of virtual buttons and the status bar. Here are some related ADB commands:

1. Display virtual keys and status bar:

   bashCopy code

   adb shell settings put global policy_control immersive.off=null

   This command turns off immersive mode and displays virtual buttons and the status bar.

2. Hide virtual keys and status bar:

   bashCopy code

   adb shell settings put global policy_control immersive.full=*

   This command is used to enter full immersion mode and hide virtual buttons and the status bar.

3. Hide only virtual keys:

   bashCopy code

   adb shell settings put global policy_control immersive.navigation=*

   This command hides the virtual key, but displays the status bar.

4. To hide only the status bar:

   bashCopy code

   adb shell settings put global policy_control immersive.status=*

   This command hides the status bar, but the virtual button is displayed.

Note that the effects of these commands may vary depending on the device and Android version. On some devices, permissions may need to be granted, while on others, virtual keys or the status bar may not be completely hidden.

In addition, you can use the following commands to programmatically simulate key events:

• Analog return key:

  bashCopy code

  adb shell input keyevent KEYCODE_BACK

• Simulate the Home button:

  bashCopy code

  adb shell input keyevent KEYCODE_HOME

• Simulate recent task key:

  bashCopy code

  adb shell input keyevent KEYCODE_APP_SWITCH

These commands can be executed in a terminal or script for control on a connected Android device. Make sure your device is connected and has the developer option and USB debugging enabled.
