(A very simple Android studio multimedia programming example, in the source code: declare an ImageButton, TextView, MediaPlayer variable, declare a Flag as a variable to acknowledge whether the music is paused and the default value is false, create TextView and ImageView objects through the findViewById constructor, create MediaPlayer objects when onCreate, store the music in res/raw/always.mp3 in the Import method, and run the button to play music in the Android system, Overwrite the OnClick event. After MediaPlayer obtains the playback resource and stop(), you must use MediaPlayer. prepare() before preparing the Playback status. Release the assignment contact between the resource and MediaPlayer so that the resource can be used by other programs. Release the assignment contact between the resource and MediaPlayer when the main program is paused.)
