I'm trying to play music in all activities in my app but when I switch between mainactivity and another activity music stopped please someone help me without using Service
MainAcivity :
ToggleButton MusicButton;
MediaPlayer mediaPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mediaPlayer = MediaPlayer.create(getApplicationContext(), R.raw.vaporv2);
if(!mediaPlayer.isPlaying()){
mediaPlayer.start();
}
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
mediaPlayer.start();
}
});
//code
#Override
protected void onPause() {
super.onPause();
if(mediaPlayer!=null && mediaPlayer.isPlaying()){
mediaPlayer.pause();
}
}
#Override
protected void onResume() {
super.onResume();
if(mediaPlayer!=null && !mediaPlayer.isPlaying()){
if(MusicButton.isChecked()){
mediaPlayer.pause();
}
else
mediaPlayer.start();
}
}
I don't know what I can do in the other activity.
You can pass the current seek position using extras, but the Music may stop while switching between activities.
I suggest that you use service then in each activity onPause event you check if you are switching to another activity in your application or not, if not send some broadcast to the service to stop playing music.

I'm trying to stop my music when the user leaves the app or clicks the home button. My application plays music even if it is in the background. How can I stop the music if the user clicks the home button? If the user returns, the music is played again.
Here is my code:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mediaPlayer = MediaPlayer.create(getApplicationContext(), R.raw.vaporv2);
if(!mediaPlayer.isPlaying()){
mediaPlayer.start();
}
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
mediaPlayer.start();
}
});
//toggle off and on :
MusicButton = (ToggleButton) findViewById(R.id.toggleButton);
MusicButton.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (MusicButton.isChecked() && mediaPlayer.isPlaying()) {
mediaPlayer.pause();
} else {
mediaPlayer.start();
}
}
});
In your Activity:
Check for two states:
on pause state: When you press home button
#Override
protected void onPause() {
super.onPause();
if(mediaPlayer!=null && mediaPlayer.isPlaying()){
mediaPlayer.pause();
}
}
on resume state: When you come back to your screen
#Override
protected void onResume() {
super.onResume();
if(mediaPlayer!=null && !mediaPlayer.isPlaying()){
mediaPlayer.start();
}
}
Since you are in Activity you can override onResume and onStop methods
and then play/pause your app.
#Override
protected void onResume() {
super.onResume();
if(!mediaPlayer.isPlaying()){
mediaPlayer.start();
}
}
#Override
protected void onStop() {
super.onStop();
mediaPlayer.pause();
}
I'm trying to play music when the user clicks in the MUSIC ON toggle button, and music will pause when he clicks in MUSIC OFF. I also need to play music when opening the app. This is my code but doesn't work:
MediaPlayer mediaPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mediaPlayer = MediaPlayer.create(getApplicationContext(), R.raw.vapor);
mediaPlayer.start();
.....
}
MusicButton = (ToggleButton)findViewById(R.id.toggleButton);
MusicButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(MusicButton.isChecked()){
mediaPlayer.start();
}
else{
mediaPlayer.stop();
mediaPlayer.release();
}
}
});
#Override
public void onPause() {
mediaPlayer.stop();
mediaPlayer.release();
super.onPause();
}
#Override
public void onResume() {
mediaPlayer = MediaPlayer.create(this, R.raw.vapor);
mediaPlayer.setLooping(false);
mediaPlayer.start();
super.onResume();
}
Error log:
java.lang.IllegalStateException
at android.media.MediaPlayer._start(Native Method)
at android.media.MediaPlayer.start(MediaPlayer.java:1384)
at com.myapp$MainActivity$2.onClick(MainActivity.java:80)
first,you should not use setOnClickListener() on ToggleButton,ToggleButton has function setOnCheckedChangeWidgetListener to listene the status of compent
second,about you error,maybe your ToggleButton is unchecked,when you clicked it, ToggleButton become checked and invoke you code mediaPlayer.start();,but you start mediaPlayer at onCreate() already,you can check it.
I am creating a game, I want to play a background music for one activity only(For main menu of game), my code shown below, The problem is that the music plays more than one time, I want to play the same music also when activity Resumes.
public class Menu extends Activity {
MediaPlayer mp
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.menu);
mp = MediaPlayer.create(Menu.this, R.raw.adalante);
if(!mp.isPlaying()) {
mp.start();
}
public void play(View ButtonClicked) {
mp.stop();
mp.release();
//mp = MediaPlayer.create(Menu.this, R.raw.l);
//mp.start();
goToActivity(Game.class);
}
#Override
public void onResume() {
super.onResume(); // Always call the superclass method first
//coins
coin.setText(data.getString("coin"));
mp = MediaPlayer.create(Menu.this, R.raw.adalante);
if(!mp.isPlaying()) {
mp.start();
}
//mps.release();
}
In your onResume don't initialise MediaPlayer again and again. It creates new instance every time when you come to onResume. So add a check in onResume like this :
#Override
protected void onResume() {
super.onResume();
if (mp==null)
mp=MediaPlayer.create(MainActivity.this,R.raw.adalante);
if (!mp.isPlaying())
mp.start();
}
and additionally add this for prevention to play when activity goes to onPause
#Override
protected void onPause() {
super.onPause();
mp.pause();
}
I am new to Android programming and i have a problem that i can not solve without your help...Please, give me a hand... ;-)
When i start playing my audio file, i can not stop it. Instead, I am quitting the application.
I play audio file with this code:
public class Word1Audio extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.word1video);
MediaPlayer mediaPlayer = MediaPlayer.create(this, R.raw.lige);
mediaPlayer.start();
}
}
HOWEVER, when i try to stop it when the back button is pressed by this piece of code
#Override
public void onBackPressed() {
// do something on back.
return;
}
my applications closes down and audio continues to play...
Do you have an idea why the application closes down? And how can i just stop the music and go back to the previous page...??
Thank you for your time and help... :-)
you could try
MediaPlayer mediaPlayer;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.word1video);
mediaPlayer = MediaPlayer.create(this, R.raw.lige);
mediaPlayer.start();
}
#Override
public void onBackPressed() {
if( mediaPlayer.isPlaying() ) {
mediaPlayer.stop();
}
super.onBackPressed();
}
I have a VideoView and it is pause when I start an Email intent. When the email intent is done, I want the videoView to continue playing, however, it restarts from the beginning.
#Override
public void onPause() {
Log.d(TAG, "onPause called");
super.onPause();
videoView.pause();
}
#Override
public void onResume() {
super.onResume();
Log.d(TAG, "onResume called");
videoView.start();//resume() doesnt work
}
How can I get the videoView to resume from where it left off.
What about this:
#Override
public void onResume() {
super.onResume();
Log.d(TAG, "onResume called");
videoView.seekTo(stopPosition);
videoView.start(); //Or use resume() if it doesn't work. I'm not sure
}
// This gets called before onPause so pause video here.
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
stopPosition = videoView.getCurrentPosition();
videoView.pause();
outState.putInt("position", stopPosition);
}
Then in your onCreate() call the stopPosition from the bundle and set it globally
#Override
protected void onCreate(Bundle args) {
super.onCreate(args);
if( args != null ) {
stopPosition = args.getInt("position");
}
Using seekTo gives a slight flickering efeect while resuming the video. Better approach would be using pause() and start() methods of MediaPlayer class instead of using methods from VideoView. The start() method of VideoView restarts the video from the beginning, but start() method of MediaPlayer resumes the video if the pause() method had been previously called.
Here is what official android doc says
public void start ()
Added in API level 1 Starts or resumes playback. If playback had
previously been paused, playback will continue from where it was
paused. If playback had been stopped, or never started before,
playback will start at the beginning.
You can get the MediaPlayer associated with a VideoView in OnPreparedListener of VideoView.
public class MainActivity extends Activity {
private MediaPlayer mMediaPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
VideoView videoView = (VideoView) findViewById(R.id.videoView1);
videoView.setVideoPath(path);
videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mMediaPlayer = mp;
}
});
}
}
Then subsequent pause() and resume() methods can be called on MediaPlayer object itself.
//To pause the video
mMediaPlayer.pause();
//To resume the video
mMediaPlayer.start();
Very simple yet efficient solution. Hope it helps!
