Learners may sometimes experience issues while playing course videos in the Android app. Common issues include videos not playing, videos getting stuck on loading, buffering, black screens, playback errors, or downloaded videos not playing. These issues can be caused by the app version, internet connection, device storage, Android system version, DRM compatibility, corrupted downloads, or temporary app data.

  • Black screen while playing
  • Video stops during playback
  • Audio is not working

Troubleshooting Steps

1. Check the Internet Connection

Make sure the Android device has a stable internet connection.

Try the following:

  1. Switch between Wi-Fi and mobile data.
  2. If using Wi-Fi, try another network if available.
  3. Avoid switching networks while the video is loading or playing.
  4. Try playing another video to check whether the issue affects all videos.

2. Update the Android App

Make sure the learner is using the latest version of the learning app.

  1. Open the Google Play Store.
  2. Search for the learning app.
  3. Check whether an update is available.
  4. Update the app.
  5. Restart the app and try playing the video again.

3. Restart the App

Completely close the Android app and open it again.

If the issue continues, restart the Android device and try playing the video again.

4. Clear App Cache

Temporary or corrupted app cache can sometimes cause video playback issues.

  1. Open Android Settings.
  2. Go to Apps.
  3. Select the learning app.
  4. Open Storage or Storage & cache.
  5. Select Clear cache.
  6. Open the app again and try playing the video.

Do not select Clear data unless instructed by the support team, as this may remove locally stored app information.

5. Check Available Storage

Make sure the device has sufficient free storage.

Low storage can cause problems with:

  • Video downloads
  • Offline video playback
  • Temporary video files
  • App operation

Free up storage if the device is running low and try again.

6. Check Android System Updates

Make sure the Android device is running a supported and updated version of Android.

Go to:

Settings → System → Software update

Install any available updates and restart the device.

7. Check Battery Saver and Data Saver

Battery Saver or Data Saver settings may restrict background network activity or affect app functionality.

Temporarily disable:

  • Battery Saver
  • Data Saver
  • Background data restrictions

Then reopen the app and try playing the video again.

8. Disable VPN or Network Filtering

If a VPN, private DNS, firewall, ad blocker, or network filtering application is enabled, temporarily disable it and try playing the video again.

These services can sometimes interfere with video or DRM license requests.

9. Check Downloaded Videos

If a downloaded video is not playing:

  1. Delete the downloaded video from the app.
  2. Make sure the device has sufficient storage.
  3. Connect to a stable internet connection.
  4. Download the video again.
  5. Wait until the download is completely finished.
  6. Try playing the downloaded video again.

Avoid interrupting the download or switching networks during the download.

10. DRM-Protected Video Issues

Some course videos may use DRM protection.

If a DRM-protected video displays an error such as License Failed, Content Play Failed, or does not start:

  1. Update the learning app.
  2. Update Android.
  3. Check the internet connection.
  4. Disable VPN or network filtering.
  5. Restart the app.
  6. Restart the device.
  7. Try playing another DRM-protected video.

If other DRM videos also fail, provide the error screenshot and device details to the support team.

11. Check Date and Time

Make sure the Android device is using the correct date and time.

Enable automatic date and time if available:

Settings → System → Date & time → Set time automatically

An incorrect device clock can sometimes affect authentication and secure media requests.

12. Reinstall the App

If the issue continues after trying the above steps:

  1. Make sure you know your login credentials.
  2. Uninstall the learning app.
  3. Restart the device.
  4. Install the latest version of the app from the official app store.
  5. Log in again.
  6. Try playing the video.

If downloaded/offline content is stored in the app, reinstalling may remove the downloaded content and require it to be downloaded again.

Common FAQs

Why is my video not playing in the Android app?

The issue may be caused by an unstable internet connection, outdated app version, corrupted app cache, insufficient storage, device restrictions, or DRM-related issues.

Why is my video stuck on loading?

Check the internet connection first. Then restart the app, clear the app cache, and try another network if available.

Why does my video keep buffering?

Buffering is commonly related to network speed or instability. Try switching between Wi-Fi and mobile data and check whether other videos have the same issue.

Why is the video showing a black screen?

A black screen may be caused by a temporary app issue, device compatibility problem, DRM playback issue, or outdated app/system software. Update the app and Android, restart the device, and try again.

Why is there no sound in the video?

Check the device's media volume and make sure the device is not muted. Also check whether audio works in other videos or applications.

Why is the video and audio out of sync?

Restart the video and app first. If the issue continues, update the app and Android system and try the video again.

Why is my downloaded video not playing?

The downloaded file may not have completed successfully or may have become corrupted. Delete the downloaded video and download it again using a stable internet connection.

Why does my downloaded video keep getting stuck?

Check available device storage and ensure the download has completed successfully. Delete the existing download and download the video again if necessary.

Why am I getting a "License Failed" error?

A License Failed error can occur when the app cannot successfully obtain or process the DRM license required to play protected content.

Check the internet connection, update the app, disable VPN/network filtering, restart the app and device, and try again.

Why does the video work on another device but not my Android phone?

The issue may be specific to the Android device, Android version, app version, available storage, network configuration, or DRM environment.

Can VPN or private DNS cause video playback problems?

Yes. VPNs, private DNS services, firewalls, and network filtering applications can interfere with video or DRM license requests. Temporarily disable them and try again.

Can low storage affect video playback?

Yes. Low storage can affect video downloads, temporary files, and offline playback. Make sure sufficient free storage is available.

Will clearing the app cache delete my downloaded videos?

Clearing the cache generally removes temporary cached files, but app behavior can vary. If downloaded videos are important, avoid clearing app data or uninstalling the app unless instructed by support.

Should I reinstall the app if the video is not playing?

Reinstalling can help if the app installation or local app data is corrupted. Before reinstalling, make sure you know your login credentials and understand that downloaded/offline content may need to be downloaded again.

What information should I provide to Support?

If the issue continues, provide:

  • Screenshot or recording of the error
  • Exact error message
  • Name of the affected video
  • Android device model
  • Android version
  • App version
  • Whether the issue affects all videos or only one video
  • Whether other DRM videos are affected
  • Whether the video works on another device
  • Whether the issue occurs on Wi-Fi and mobile data
  • Whether the video is streamed or downloaded

This information helps the support team determine whether the issue is related to the Android app, device, network, downloaded content, or DRM configuration.
