Playing music (in-game sound effects)

In the previous article, we learned how to play music in a specified sdcard, but how to implement the sound effects in the game?

The game must be packaged and released with the program. Such music is not stored in sdcard, and is usually stored in "Res/raw" under the application directory. How can we play music?

Actually, it is very simple. I just changed the setdatasource () method to the CREATE () method to specify the mediaplayer object of the Resource Index.
