The Android SDK’s MediaPlayer component can be used to play both audio and video content. It can play from a web-based resource with a URL, but can also be used to play local files stored on the device. When you package an app and want to include an audio file, one of the most common places to store it is in the assets directory. This directory contains files your app needs, but unlike resources these files aren’t associated with a resource id. Instead, you refer to them by name using the current context and a reference to the app package’s assets.
- [Narrator] The Android SDK media player component…can be used to play both audio and video content.…It can play from a web-based resource with a URL,…but can also be used to play local files…stored on the device.…When you package an app and include an audio file,…one of the most common places to include it…is in the assets folder.…This is a folder under the application module…which can contain arbitrary files of any format.…These files aren't associated with a resource ID…and the media player component can't play an audio…or video file directly from this folder.…
In order to use it, you have to copy it…to the device's file system,…usually to internal or external storage.…I'm going to demonstrate this using this beginning app…where I've included an MP3 file in the assets directory.…I'm going to open this file in Explorer on Windows,…or you can do this in Finder on Mac,…and I'll double-click and play it.…So my goal is to copy that MP3 file to internal storage…and then play it with the media player component.…
