I have an Android app. I created a class for the media menu. When I return from the media menu to the main activity, the sound works, but if I return to the media menu again, the sound does not cut off. Moreover, if I then press the pause button, the application crashes!
How can I solve this issue? I have thought of a lot of solutions except that I cannot create a destroy function because it is not present in the options.
Here is my code:
play.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (mdp == null) {
mdp = MediaPlayer.create(context, d.getsound());
mdp.start();
} else {
mdp.pause();
mdp = MediaPlayer.create(context, d.getsound());
mdp.start();
}
}
});
Give this a shot my friend
#Override
public void onPause(){
super.onPause();
mdp.stop();
mdp.release();
}

// This is my app exit button it destroys the activity and exits the user from an app. I want to //play a sound when I click this button but unfortunately, the sound is not playing and the activity //destroys. Please help me in solving this issue. Except for this button, all my button sound is working.
// This is my second activity, in this activity, I have used a button for quitting the app but I also //want the button to play a sound when the button is clicked by user. But it is not playing the sound and //quits the app which destroys activity. please tell me how to play the sound on my exit button during //the click
mExitApp = (Button)findViewById(R.id.exit_app);
final MediaPlayer mp = MediaPlayer.create(this, R.raw.sample2);
mExitApp.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.start();
ScoreActivity.this.finish();
System.exit(0);
}
});
A quick and dirty way would be to wait for the sound to end playing before finishing the activity/process.
public void onClick(View v) {
mp.start();
final Handler handler = new Handler(Looper.getMainLooper());
handler.postDelayed(new Runnable() {
#Override
public void run() {
ScoreActivity.this.finish();
System.exit(0);
}
}, 300);
}
A more cleaner solution would probably involve a MediaPlayer.OnCompletionListener.
mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
finish(); // finish current activity
}
});
Or you could play the sound in a foreground/background service. But then you shouldn't kill the entire process (System.exit(0)) like you do now ofc.
In my project I am trying to make a media player which plays a shoutcast stream. Everything seemed to be working well until I pressed the back button on my device, which I think stops the activity and causes the device to recreate the activity when launched again. The problem is , when the activity is recreated , I lose the control of the mediaplayer and a new mediaplayer is created.
I need to be able to have the mediaplayer's control back at that point. How is it possible?
This part of code belongs to onCreate
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn = (Button) findViewById(R.id.button);
if (mediaPlayer == null){
mediaPlayer = new MediaPlayer();
try {
mediaPlayer.setDataSource(getString(R.string.yayin));
} catch (Exception e) {
e.printStackTrace();
}
mediaPlayer.prepareAsync();
}
if(!isPlaying){
btn.setBackgroundResource(R.drawable.oynat);
}
else{
btn.setBackgroundResource(R.drawable.durdur);
}
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(!isPlaying){
playOnReady();
isPlaying = true;
btn.setBackgroundResource(R.drawable.durdur);
}
else{
mediaPlayer.reset();
isPlaying = false;
btn.setBackgroundResource(R.drawable.oynat);
}
}
});
This part of code belongs to the function playOnReady()
private void playOnReady(){
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
}
Take a look at the Android Activity lifecycle flowchart: https://developer.android.com/reference/android/app/Activity.html#ActivityLifecycle
You need to account for the path where onPause is called when you leave the Activity and then onResume is called when you enter it again. The solution for you could be as simple as moving some/all of your code from onCreate into onResume.
Using this tutorial I have managed to build a service which handles the mediaplayer that I can have the control of anytime I need.
i am searched many solution but could not find proper result when i press the back button of mobile i am using one counter variable and put the condition like when counter is 0 it called the music file.
but when i am comeout from that activity means press back button of mobile still that activity is runnig and called the music file .i am using this below code for music play.please anyone have solution then help me.i am using one timer function.like this when i==0 that time call one music file but when i press back button. this timer i wants to stop.
public void btntimer(){
new Handler().postDelayed((new Runnable() {
#Override
public void run() {
if(i!=32) {
matchNo();
}
else {
try{
showdialog();
media=1;
}catch (Exception e){
media=0;
}
updatepoints();
}
}
}), 4000);
}
song=MediaPlayer.create(this,R.raw.cartoon1);
song.start();
song.setLooping(false);
If I understand you correct, you want to stop playing music on back button pressed.
Call stop() in onBackPressed method.
#Override
public void onBackPressed() {
song.stop();
song.release();
song = null;
}
I have recently tried to create a button that says "Play", and when this button is pressed, I wanted it to play the music then change the text to "Stop", but it throws an error and quits the app. Here is my code:
mPlay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(ourMusic.isPlaying()){
ourMusic.pause();
mDisplay.setText("Play");
}else{
ourMusic = MediaPlayer.create(MainActivity.this, R.raw.killthenoise);
ourMusic.start();
mDisplay.setText("Stop");
}
}
});
So if you press the button once it should play, press it again it should stop the music. There is no errors in the actual coding.
Here is my logcat: http://pastie.org/7970711
I am new to this stuff, so I don't know too much of whats going on. Any help would be appreciated.
Use this instead:
#Override
public void onClick(View v) {
if (ourMusic == null) {
ourMusic = MediaPlayer.create(MainActivity.this, R.raw.killthenoise);
}
if(ourMusic.isPlaying()){
ourMusic.pause();
mDisplay.setText("Play");
}else{
ourMusic.start();
mDisplay.setText("Stop");
}
}
Basically don't:
Recreate ourMusic everytime there is a click to play
Try to use ourMusic when it isn't instantiated.
Add a global variable boolean flag=false;
if(flag==false)
{
mp=MediaPlayer.create(this, R.raw.abc);
mp.start();
playbutton.setText("Pause");
flag=true;
}
else if(mp.isPlaying()&&flag==true)
{
mp.pause();
playbutton.setText("Play");
flag=false;
}
This code will work if you want to use the same button as PLAY/PAUSE in your app.
Hope this helps.
I made a basic app with 2 buttons, start and stop. When I start the app and hit the start button the sound starts, and when I the end button it stops, BUT if I try to start up again with the start button it doesn't start again.
Code:
buttonStart = (Button)findViewById(R.id.ButtonStart);
buttonStart.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
onClickButton(buttonStart);
}
});
buttonEnd = (Button)findViewById(R.id.ButtonEnd);
buttonEnd.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
onClickButton(buttonEnd);
}
});
beat = MediaPlayer.create(this, R.raw.beat);
public void onClickButton(Button button){
if(button == buttonStart){
beat.start();
beat.setLooping(true);
}
else if(button == buttonEnd){
beat.stop();
//beat.setLooping(false);
}
}
if you stop the media player then the instance of the media player is destroyed so if you want to play again. Then you have to create the instance of media player again. Put this code in your buttonStart
beat = MediaPlayer.create(this, R.raw.beat);
beat.start();
beat.setLooping(true);
Best of luck and don't forget to tick that this answer is useful to you.
