  • Error message: "Playback stopped because USB debugging was detected. Please disable USB debugging."
  • Summary: This issue occurs when video playback is blocked on an Android device that has USB debugging mode enabled.

Symptoms​

When you attempt to play a video on an Android device with USB debugging mode enabled, an error message appears and playback stops.

Cause​

Starting from App Player for Android v2.1.6, a security policy is applied that restricts playback when USB debugging mode is enabled. USB debugging mode is a feature used in developer environments, and playback is not permitted in that state to protect content security.

Resolution​

You can resume playback by disabling USB debugging. The menu path may vary depending on the manufacturer and Android version.

If developer options are disabled​

If developer options are not visible, enable them first by following the steps below.

  1. Launch the [Settings] app from the device's home screen.
  2. Navigate to [System] > [About phone].
  3. Tap 'Build number' seven times in a row. When the message "You are now a developer!" appears, the option has been successfully enabled.
  4. Then continue with the steps below.

Disable usb debugging​

  1. Navigate to [Settings] > [System] > [Developer options].
  2. Find the 'USB debugging' option and disable it (OFF).
  3. Return to the app and try playing the video again.
