I'm playing sound in android audio player activity. when i pause that activity, the sound keep on playing in background. I want to stop that sound when i resume that audio player activity.
here is my code..
can anyone help how i could do this.any help would be much appreciated, thank you :)

you should use AUDIO FOCUS and onfocuschangelistener it will solve your problem.

help me, I'm a beginner, I'm trying to make an application in which there is audio that needs to be played, I try to use MediaPlayer, so that the audio can be played and paused, I have implemented these 3 mediaplayer with setOnCompletion and array methods when calling the audio folder,like this:
mediaPlayer.setOnCompletionListener(completionListener);
MediaPlayer.OnCompletionListener completionListener = new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
play++;
if (play < playList.length) {
mediaPlayer = MediaPlayer.create(BackGroundSound.this, playList[play]);
mediaPlayer.start();
} else {
play = 0;
mediaPlayer = MediaPlayer.create(BackGroundSound.this, playList[play]);
mediaPlayer.start();
}
}
};
and this array for file MediaPlayer:
int[] playList = new int[3];
playList[0] = R.raw.madtarqiqc1;
playList[1] = R.raw.madtarqiqc2;
playList[2] = R.raw.madtarqiqc3;
but when I clicked button, the program that I made does not work, the medialayer and button no response, what should I add, I have redesigned this code many times but the results remain the same, is there a code or method that was missed?
This is for the full source code that I have:
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
MediaPlayer mediaPlayer;
ImageButton btn1, btn2, btn3;
int[] playList;
int play = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn1 = (ImageButton) findViewById(R.id.play_toggle_ratarqiq1);
btn2 = (ImageButton) findViewById(R.id.play_toggle_ratarqiq2);
btn3 = (ImageButton) findViewById(R.id.play_toggle_ratarqiq3);
int[] playList = new int[3];
playList[0] = R.raw.madtarqiqc1;
playList[1] = R.raw.madtarqiqc2;
playList[2] = R.raw.madtarqiqc3;
mediaPlayer = MediaPlayer.create(this, playList[play]);
mediaPlayer.setOnCompletionListener(completionListener);
}
MediaPlayer.OnCompletionListener completionListener = new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
play++;
if (play < playList.length) {
mediaPlayer = MediaPlayer.create(MainActivity.this, playList[play]);
mediaPlayer.start();
} else {
play = 0;
mediaPlayer = MediaPlayer.create(MainActivity.this, playList[play]);
mediaPlayer.start();
}
}
};
#Override
public void onClick(View view) {
switch (view.getId()){
case R.id.play_toggle_ratarqiq1:
playMusic(0);
break;
case R.id.play_toggle_ratarqiq2:
playMusic(1);
break;
case R.id.play_toggle_ratarqiq3:
playMusic(2);
break;
}
}
private void playMusic(int position) {
mediaPlayer.stop();
mediaPlayer = MediaPlayer.create(this, playList[position]);
mediaPlayer.start();
changeView(position);
}
private void changeView(int position) {
if (position == 0) {
btn1.setImageResource(R.drawable.ic_play_circle_outline_black_24dp);
btn2.setImageResource(R.drawable.ic_pause_circle_outline_black_24dp);
btn3.setImageResource(R.drawable.ic_pause_circle_outline_black_24dp);
} else if (position == 1) {
btn1.setImageResource(R.drawable.ic_pause_circle_outline_black_24dp);
btn2.setImageResource(R.drawable.ic_play_circle_outline_black_24dp);
btn3.setImageResource(R.drawable.ic_pause_circle_outline_black_24dp);
} else if (position == 2) {
btn1.setImageResource(R.drawable.ic_pause_circle_outline_black_24dp);
btn2.setImageResource(R.drawable.ic_pause_circle_outline_black_24dp);
btn3.setImageResource(R.drawable.ic_play_circle_outline_black_24dp);
}
}
}
There are few crucial things that you missed :
to set onClickListner() in those Button objects
to reuse the MediaPlayer instance(you created new one everytime you need)
to properly update the play variable which I believe is the index of currently played song
I tried to make it fully readable as I can. Here is the code for MainActivity:
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
private MediaPlayer mediaPlayer;
private ImageButton btn1, btn2, btn3;
private int[] playList;
// initializing it to -1 so that it is out of bounds of the array playList
private int play = -1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn1 = findViewById(R.id.play_toggle_ratarqiq1);
btn2 = findViewById(R.id.play_toggle_ratarqiq2);
btn3 = findViewById(R.id.play_toggle_ratarqiq3);
// you forgot to setonclicklistener in these buttons thats why they were not reponding
btn1.setOnClickListener(this);
btn2.setOnClickListener(this);
btn3.setOnClickListener(this);
playList = new int[3];
playList[0] = R.raw.madtarqiqc1;
playList[1] = R.raw.madtarqiqc2;
playList[2] = R.raw.madtarqiqc3;
// use constructor to create a mediaplayer object rather than this static create method
// mediaPlayer = MediaPlayer.create(this, playList[play]);
mediaPlayer = new MediaPlayer();
mediaPlayer.setOnCompletionListener(completionListener);
}
MediaPlayer.OnCompletionListener completionListener = new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
play++;
if (play < playList.length) {
// we will not assign mediaPlayer to new instance instead we will only change data source
// and reuse the single instance everywhere in this activity
// mediaPlayer = MediaPlayer.create(MainActivity.this, playList[play]);
try {
mediaPlayer.setDataSource(MainActivity.this, Uri.parse("android.resource://" + getPackageName() + "/res/raw/"
+ getResources().getResourceName(playList[play])));
mediaPlayer.start();
} catch (IOException e) {
// if things goes wrong we will show Toast
Toast.makeText(MainActivity.this, e.getMessage(), Toast.LENGTH_LONG).show();
}
} else {
play = 0;
try {
mediaPlayer.setDataSource(MainActivity.this, Uri.parse("android.resource://" + getPackageName() + "/res/raw/"
+ getResources().getResourceName(playList[play])));
mediaPlayer.start();
} catch (IOException e) {
Toast.makeText(MainActivity.this, e.getMessage(), Toast.LENGTH_LONG).show();
}
}
}
};
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.play_toggle_ratarqiq1:
// you can check to see if the song that we want to play is already being played
// so that in that case you can pause it and resume on next click later
// but I leave it to you for the implementation
playMusic(0);
break;

playMusic(1);
break;
case R.id.play_toggle_ratarqiq3:
playMusic(2);

}
}
private void playMusic(int position) {
// with the code below, for the first time the mediaplayer wouldn't have started playing
// and you would have already called stop() on it.
// mediaPlayer.stop();
// Also, assigning mediaPlayer obj to new instance will wipe out the onCompletionListener
// you set earlier.
// mediaPlayer = MediaPlayer.create(this, playList[position]);
// check to see if mediaplayer is playing to reset it if it is
if (mediaPlayer.isPlaying() || mediaPlayer.)
mediaPlayer.reset();
// now that it is in idle state, set data source in it
try {
mediaPlayer.setDataSource(this, Uri.parse("android.resource://" + getPackageName() + "/res/raw/"
+ getResources().getResourceName(playList[position])));
// start playback and change btn images accordingly
mediaPlayer.start();
changeView(position);
// also you forgot to update play variable to indicate the index of current song
// that is being played
play = position;
} catch (IOException e) {
Toast.makeText(MainActivity.this, e.getMessage(), Toast.LENGTH_LONG).show();
}
}
private void changeView(int position) {
// I guess this needs a little bit of modification as
// For eg: if btn1 is clicked, btn1 should show pause img in theory
// same goes for all other buttons
// try to handle it yourself
if (position == 0) {
btn1.setImageResource(R.drawable.ic_play_circle_outline_black_24dp);
btn2.setImageResource(R.drawable.ic_pause_circle_outline_black_24dp);
btn3.setImageResource(R.drawable.ic_pause_circle_outline_black_24dp);

Just like a view holder has the method getAdapterPosition(), I want to write my own setAdapterPosition() for the view holder(which doesn't exist).
What am I working on?
Currently, I am working on a project wherein I have to list 10 songs in the form of a recycler view and then play them, if any particular song is clicked. Each list item contains the song name, a seek bar and a play button
I have implemented this part, by adding all the media player contros inside the adapter class.
What do I want?
Currently, this model used mediaPlayer.setLooping(true) so that as soon as a song finished, it kept looping till some other song is clicked for playing.
Now I want to extend this model to an "autoplay" version so that as soon as a song is finished, the next song is played
What is the problem?
The seekBar progress and playButton image transition to a pauseButton image were happening with the call
viewHolder.seekBar.setProgress(...)
viewHolder.playButton.setImageDrawable(...)
Since this was happening on the
viewHolder.itemView.setOnClickListener(...)
as soon as a new song was clicked, the seekBar and playButton image were being updated.
Now, when the song is completed, I don't want the user to click on the next song to play it. I want it to be autoplayed, but I am unable to understand, how do I change myViewHolder position accordingly.
Suppose Song 0 has finished playing and Song 1 has started playing, viewHolder.getAdapterPosition() still returns 0 instead of 1. Hence the seekBar & playButton of song 0 is being updated and not of song 1.
I want to be able to do something like this
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
int nextSongPosition, currentSongPosition;
currentSongPosition = viewHolder.getAdapterPosition();
if(currentSongPosition==(songs.size()-1)){
nextSongPosition = 0;
//do some miracle so that viewHolder.getAdapterPosition() now shows 0 instead of currentSongPosition
}else{
nextSongPosition = currentSongPosition + 1;
//do some miracle so that viewHolder.getAdapterPosition() now shows nextSongPosition instead of the currentSongPosition;
}
}
});
As clear from the question statement, I want to implement something similar to a setAdapterPosition() which doesn't exist.

I made a simple music player which can play some songs in the background. Going to the homescreen and reopening the app through notification works as well. The only Problem I have is that when music playing is complete and if I press the back button(going to parent activity) in the music player activity my app crashes.How can I fix this problem?

I needed to connect my SeekBar with my MediaPlayer in my App.
I set up the SeekBar via xml like this:
<SeekBar
android:id="#+id/song_seekbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"/>
and followed this SO answer to implement it.
This is my code:
public class Song_main extends AppCompatActivity {
private final int SONG_REQUEST_CODE = 1;
private Uri song;
private TextView selectSong;
private SeekBar seekBar;
private Handler handler;
private MediaPlayer mediaPlayer;
private boolean repeatPressedTwice = false;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.app_bar_song_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.song_main_toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
seekBar = (SeekBar) findViewById(R.id.song_seekbar);
handler = new Handler();
notSelected();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.song, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.song_plus) {
Intent selectIntent = new Intent(Intent.ACTION_GET_CONTENT);
selectIntent.setType("audio/*");
startActivityForResult(selectIntent, SONG_REQUEST_CODE);
}
return true;
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == SONG_REQUEST_CODE && resultCode == Activity.RESULT_OK) {
if ((data != null) && (data.getData()!=null)) {
song = data.getData();
setup();
}
}
}
private void notSelected() {
selectSong = (TextView) findViewById(R.id.select_song_textview);
selectSong.setText(getResources().getString(R.string.song_not_selected));
}
public void onPlayButtonClicked(View v) {
ImageButton pb = (ImageButton) findViewById(R.id.song_play_button);
if (!mediaPlayer.isPlaying()) {
mediaPlayer.start();
pb.setImageResource(R.drawable.pause);
updateSeekBar();
} else {
mediaPlayer.pause();
pb.setImageResource(R.drawable.ic_play_arrow_white_24dp);
}
}
public void onControlsClicked(View v) {
if (v.getId() == R.id.fast_forward) {
int pos = mediaPlayer.getCurrentPosition();
pos += 1500;
mediaPlayer.seekTo(pos);
}
else if (v.getId() == R.id.fast_backward) {
int pos = mediaPlayer.getCurrentPosition();
pos -= 1500;
mediaPlayer.seekTo(pos);
}
else if (v.getId() == R.id.skip_backward) {
mediaPlayer.seekTo(0);
}
}
public void onRepeatClicked(View v) {
if (!repeatPressedTwice) {
// TODO: change visual color of repeat button

}
}
private void setup() {
/* the song has been select setup the interface */
/* displays song name in title */
TextView titleView = (TextView) findViewById(R.id.song_appbar_title);
String songName;
ContentResolver contentResolver = this.getContentResolver();
Cursor cursor = contentResolver.query(song, null, null, null, null);
if (cursor != null && cursor.moveToFirst()) {
songName = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
titleView.setText(songName);
}
/* removes the notSelected String */
selectSong.setVisibility(View.GONE);
/* setup media player */
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mediaPlayer.setDataSource(getApplicationContext(), song);
mediaPlayer.prepareAsync();
} catch (IOException e) {
Toast.makeText(this, "file not found", Toast.LENGTH_SHORT).show();
}
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
/* show media player layout */
RelativeLayout mpl = (RelativeLayout) findViewById(R.id.media_player_layout);
mpl.setVisibility(View.VISIBLE);
mediaPlayer.start();
ImageButton pb = (ImageButton) findViewById(R.id.song_play_button);
pb.setImageResource(R.drawable.pause);
}
});
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
ImageButton pb = (ImageButton) findViewById(R.id.song_play_button);
pb.setImageResource(R.drawable.ic_play_arrow_white_24dp);
}
});
seekBar = (SeekBar) findViewById(R.id.song_seekbar);
seekBar.setMax(mediaPlayer.getDuration());
updateSeekBar();
}
private void updateSeekBar() {
seekBar.setProgress(mediaPlayer.getCurrentPosition()/1000);
handler.postDelayed(runnable, 1000);
}
Runnable runnable = new Runnable() {
#Override
public void run() {
updateSeekBar();
}
};
#Override
public void onStop() {
super.onStop();
if (mediaPlayer!=null)
mediaPlayer.stop();
}
}
The process starts from the onOptionsItemSelected method.
The seekBar behaves correctly, it increments every second. The problem now is that it finishes way before the song finishes.
I tried adding
seekBar.setMax(mediaPlayer.getDuration());
in the setup method, but that causes the bar not to move at all.
You need to define separate Runnable and trigger it every x miliseconds (depends on you) once MediaPlayer starts.
Define a function updateSeekbar like,
private void updateSeekBar() {
audioSeek.setProgress(player.getCurrentPosition());
txtCurrentTime.setText(milliSecondsToTimer(player.getCurrentPosition()));
seekHandler.postDelayed(runnable, 50);
}
And Runnable
Runnable runnable = new Runnable() {
#Override
public void run() {
updateSeekBar();
}
};
Now you just have to call updateSeekbar once when playing starts. In your case:
public void onPlayButtonClicked(View v) {
ImageButton pb = (ImageButton) findViewById(R.id.song_play_button);
if (!mediaPlayer.isPlaying()) {
mediaPlayer.start();
pb.setImageResource(R.drawable.pause);
updateSeekBar();
} else {
mediaPlayer.pause();
pb.setImageResource(R.drawable.ic_play_arrow_white_24dp);
}
}
FYI
Function milliSecondsToTimer works as follows
private String milliSecondsToTimer(long milliseconds) {
String finalTimerString = "";
String secondsString = "";
// Convert total duration into time
int hours = (int) (milliseconds / (1000 * 60 * 60));
int minutes = (int) (milliseconds % (1000 * 60 * 60)) / (1000 * 60);
int seconds = (int) ((milliseconds % (1000 * 60 * 60)) % (1000 * 60) / 1000);
// Add hours if there
if (hours > 0) {
finalTimerString = hours + ":";
}
// Prepending 0 to seconds if it is one digit
if (seconds < 10) {
secondsString = "0" + seconds;
} else {
secondsString = "" + seconds;
}
finalTimerString = finalTimerString + minutes + ":" + secondsString;
// return timer string
return finalTimerString;
}
UPDATE
You have called setMax at the wrong place. Update setup() function as follows
private void setup() {
/* the song has been select setup the interface */
/* displays song name in title */
TextView titleView = (TextView) findViewById(R.id.song_appbar_title);
String songName;
ContentResolver contentResolver = this.getContentResolver();
Cursor cursor = contentResolver.query(song, null, null, null, null);
if (cursor != null && cursor.moveToFirst()) {
songName = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
titleView.setText(songName);
}
/* removes the notSelected String */
selectSong.setVisibility(View.GONE);
/* setup media player */
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mediaPlayer.setDataSource(getApplicationContext(), song);
mediaPlayer.prepareAsync();
} catch (IOException e) {
Toast.makeText(this, "file not found", Toast.LENGTH_SHORT).show();
}
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
/* show media player layout */
seekBar.setMax(mediaPlayer.getDuration());
RelativeLayout mpl = (RelativeLayout) findViewById(R.id.media_player_layout);
mpl.setVisibility(View.VISIBLE);
mediaPlayer.start();
updateSeekBar();
ImageButton pb = (ImageButton) findViewById(R.id.song_play_button);
pb.setImageResource(R.drawable.pause);
}
});
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
ImageButton pb = (ImageButton) findViewById(R.id.song_play_button);
pb.setImageResource(R.drawable.ic_play_arrow_white_24dp);
}
});
}
You have implement OnSeekBarChangeListener and in onCreate() add the below line:-
seekBar = (SeekBar) findViewById(R.id.seekBar);
And override the onProgressChanged() method , in this method you can set the progress in the seekbar using the below line:
mPlayer.seekTo(progress);
seekBar.setProgress(progress);
or
After you initialise your MediaPlayer and for example press the play button, you should create an handler and post runnable so you can update your SeekBar (in the UI thread itself) with the current position of your MediaPlayer like this :
private Handler mHandler = new Handler();
//Make sure you update Seekbar on UI thread
MainActivity.this.runOnUiThread(new Runnable(){
#Override
public void run() {
if(mMediaPlayer != null){
int mCurrentPosition = mMediaPlayer.getCurrentPosition() / 1000;
mSeekBar.setProgress(mCurrentPosition);
}
mHandler.postDelayed(this, 1000);
}
});
and update that value every second.
If you need to update the MediaPlayer's position while user drag your SeekBar you should add OnSeekBarChangeListener to your SeekBar and do it there :
mSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
if(mMediaPlayer != null && fromUser){
mMediaPlayer.seekTo(progress * 1000);
}
}
});
you need to update your Seek bar when you play a song
public void updateProgressBar() {
runOnUiThread(new Runnable() {
#Override
public void run() {
mHandler.postDelayed(mUpdateTimeTask, 100);
}
});
}
Below Runnable method to update seekbar
private Runnable mUpdateTimeTask = new Runnable() {
public void run() {
if (MusicService.isRunning()) {
duration = MusicService.getDur();
long currSongPosition = MusicService.getPosn();
totTime.setText(Utility.milliSecondsToTimer(duration));
fromTime.setText(Utility.milliSecondsToTimer(currSongPosition));
int progress = Utility.getProgressPercentage(currSongPosition, duration);
songProgressBar.setProgress(progress);
updateProgressBar();
}
}
};
Using this below function you can get progress percentage from song current position and song duration
public static int getProgressPercentage(long currentDuration, long totalDuration) {
Double percentage;
long currentSeconds = (int) (currentDuration / 1000);
long totalSeconds = (int) (totalDuration / 1000);
percentage = (((double) currentSeconds) / totalSeconds) * 100;
return percentage.intValue();
}
I have a videoview and listview/gridview in my playvideo activity.
One video is already playing in the videoview. But now i want to play the other video which are showing in the listview/gridview how can i do that?

When opening starting the app you need to get the data and store on a variable or into database.
Create a ChannelList type List (List<ChannelList>) and store ChannelList data into it.
List<ChannelList> list = new ArrayList<>(); // containing all data
You can store Title, VideoUrl, iconUrl and add it to the list.
When clicking on a List Item you will get the position by using setOnItemClickListener.
And then use the position to get the clicked ChannelList position.
Suppose your list type variable is channelList.
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
ChannelList channelList= list.get(position);
// now you have all data of clicked ChannelList
// do whatever you like
//channelList.getVideoUrl(); etc as your getter method
}
}
});
