Android VideoView: Key Tips

When using Android VideoView, please keep the following in mind:

1. Resource file: Make sure the video file is present and has been added to the project’s resource folder.
2. Permissions: Add the necessary permissions in the AndroidManifest.xml file, such as read external storage permission (READ_EXTERNAL_STORAGE) and internet access permission (INTERNET).
3. File path: To access video files stored on an external device, the correct file path must be used.
4. Supported formats: VideoView has limited support for video formats, make sure that the video file is in a supported format such as MP4, 3gp, etc.
5. Control video playback: Use the start() and pause() methods of VideoView to control the playback of the video.
6. Video size and aspect ratio: Adjust the size and aspect ratio of the VideoView according to your needs by setting LayoutParams to adjust the view size.
7. Monitor video status: You can use methods like setOnPreparedListener() and setOnCompletionListener() to listen for the video’s preparation and completion status.
8. Error handling: VideoView may encounter errors while processing videos, which can be managed by setting the setOnErrorListener() method.
9. Resource release: It is necessary to release the resources occupied by the VideoView in a timely manner when the Activity is destroyed, by calling the suspend() method of the VideoView in the onDestroy() method.
10. Compatibility: Different Android devices may have varying levels of support for video playback, requiring compatibility testing and adaptation as needed.
