Enabling USB Debugging on an Android Device

The steps to enable USB debugging depend on the version of Android running on the target device, as indicated in the following table:

Android Device Instructions

Android 4.0 and newer (Jelly Bean)

Enable the USB Debugging option under Settings > Developer options.

For Android 4.2 and newer, Developer options is hidden by default; use the following steps:

  1. On the device, go to Settings > About <device>.
  2. Tap the Build number seven times to make Settings > Developer options available.
  3. Then enable the USB Debugging option.
    Tip: You might also want to enable the Stay awake option, to prevent your Android device from sleeping while plugged into the USB port.

Click OK to allow USB debugging on your PC. If you accidentally click Cancel, disconnect your device from your PC and connect it back to make the dialog show up again on your device.


If your Android device is not correctly detected by RAD Studio or the system Device Manager, follow the steps above to verify that USB debugging is enabled.
