Develop Reference

Android is hanging when I press button to play music in second time

I used these codes from this reference. They want to click on button to play music and then click again to stop playing. (in their comment they said it was worked for them but hanging for me)
It is work just for first time. I mean for first click the music is playing. for second click the music is stop but for third click the phone emulator show this error:
unfortunately your program has stopped.
This is my code:
public MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn=(Button) findViewById(R.id.btnRain);
//mp = MediaPlayer.create(this, R.raw.rain);
mp = MediaPlayer.create(MainActivity.this, R.raw.rain);
btn.setOnClickListener(new View.OnClickListener() {
#Override
//MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.soundFileName);
// mp.start();
public void onClick(View v) {
if (mp.isPlaying()) {
mp.stop();
mp.release();
}
else {
mp.start();
}
}
});
}

In onCreate initialize mp as :
mp = new MediaPlayer();
The error is you are releasing the media player object mp, which destroys the object, call reset method instead of release.
if (mp.isPlaying())
{
mp.stop();
mp.reset();
}
else {
mp = MediaPlayer.create(LegalActivity.this, R.raw.free1);
mp.start();
}

use this below code for play and pause the music:
public MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn=(Button) findViewById(R.id.btnRain);
//mp = MediaPlayer.create(this, R.raw.rain);
mp = MediaPlayer.create(MainActivity.this, R.raw.rain);
btn.setOnClickListener(new View.OnClickListener() {
#Override
//MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.soundFileName);
// mp.start();
public void onClick(View v) {
if (mp.isPlaying()) {
mp.pause();
}
else {
mp.start();
}
}
});
}

This is an AUDIO activity that works fine and it allows you to upload songs with a spinner.
public class AUDIO extends Activity{

How to start MediaPlayer after it has been stopped in android

I am new to Android and in my app I am working with MediaPlayer.
When I first tap the start button, the song plays, but when I tap the stop button and then I tap on the start button again, the song does not start playing again. Here's what I have so far:
public class PlayngUrlFiles extends AppCompatActivity {
Button start, pause, stop;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playingurls_layout);
start = (Button) findViewById(R.id.button1);
pause = (Button) findViewById(R.id.button2);
stop = (Button) findViewById(R.id.button3);
final MediaPlayer mp = new MediaPlayer();
try {
mp.setDataSource("http://programmerguru.com/android-tutorial/wp-content/uploads/2013/04/hosannatelugu.mp3");
mp.prepare();
} catch (Exception e) {
e.printStackTrace();
}
start.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.start();
}
});
pause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.pause();
}
});
stop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.stop();
}
});
}
}

Try this :
stop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mp != null) {
mp.stop();
mp.release();
}
}
});

just check like this way
if(mdpl.isPlaying()){
mdpl.pause();
} else {
mdpl.start();
}

You can not call start, it media player in on stop state. Take a look on the state diagram of media player MediaPlayer state diagram.
When you call stop, you have to call release(), and with start you get a new media player, or just call reset.

try this
public void onStopBtnClick(View view) {
if (mAudioHelper != null) {
mAudioHelper.stop();
displayMessage("Stopping!");
}
}

Here is code to set sound file.
if (mPlayer != null) {
mPlayer.stop();
mPlayer.release();
}
mPlayer = new MediaPlayer();
AppLog.d("Created new Media player");
try {
mPlayer.setDataSource(fileName);
} catch (IOException e) {
AppLog.e("Can't open " + fileName + " file", e);
}
Before playing u should call the mPlayer.prepareAsync() function.
if you want to pause/play you have to use this code:
if (mediaPlayer.isPlaying()){
mediaPlayer.pause();
} else {
mediaPlayer.start();
}
If you want to stop player use this:
if (mPlayer != null){
mPlayer.stop();
mPlayer.release();
}
mPlayer = null;
If you want to start song again use first functions and next with this steps

This code may help you..
#Override
protected void onDestroy() {
super.onDestroy();
destroyMediaPlayer();
}
private void destroyMediaPlayer() {
if (mediaPlayer != null) {
try {
mediaPlayer.release();
Log.d("here", "destroy");
} catch (Exception e) {
e.printStackTrace();
}
}
}

SOLUTION 1
for this solution, I took some info from here
public class PlayngUrlFiles extends AppCompatActivity {
Button start, pause, stop;
MediaPlayer mp;
/**
* remain false till media is not completed, inside OnCompletionListener make it true.
*/
private boolean initialStage = true;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playingurls_layout);
start = (Button) findViewById(R.id.button1);
pause = (Button) findViewById(R.id.button2);
stop = (Button) findViewById(R.id.button3);
start.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (initialStage) {
mp = new MediaPlayer();
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
new Player()
.execute("http://programmerguru.com/android-tutorial/wp-content/uploads/2013/04/hosannatelugu.mp3");
} else {
if (mp && !mp.isPlaying())
mp.start();
}
}
});
pause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp && mp.isPlaying())
mp.pause();
}
});
stop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp) {
mp.stop();
mp.release();
mp = null;
initialStage = true;
}
}
});
}
/**
* preparing mediaplayer will take sometime to buffer the content so prepare it inside the background thread and starting it on UI thread.
* #author piyush
*
*/
class Player extends AsyncTask<String, Void, Boolean> {
private ProgressDialog progress;
#Override
protected Boolean doInBackground(String... params) {
// TODO Auto-generated method stub
Boolean prepared;
try {
mp.setDataSource(params[0]);
mp.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
// TODO Auto-generated method stub
initialStage = true;
mp.stop();
mp.reset();
}
});
mp.prepare();
prepared = true;
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
Log.d("IllegarArgument", e.getMessage());
prepared = false;
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
prepared = false;
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
prepared = false;
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
prepared = false;
e.printStackTrace();
}
return prepared;
}
#Override
protected void onPostExecute(Boolean result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
if (progress.isShowing()) {
progress.cancel();
}
Log.d("Prepared", "//" + result);
mp.start();
initialStage = false;
}
public Player() {
progress = new ProgressDialog(PlayngUrlFiles.this);
}
#Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
this.progress.setMessage("Buffering...");
this.progress.show();
}
}
}
SOLUTION 2
in order to avoid data downloding, try this
public class PlayngUrlFiles extends AppCompatActivity {
Button start, pause, stop;
boolean prepared;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playingurls_layout);
start = (Button) findViewById(R.id.button1);
pause = (Button) findViewById(R.id.button2);
stop = (Button) findViewById(R.id.button3);
final MediaPlayer mp = new MediaPlayer();
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
prepared = false;
mp.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
prepared = true;
mp.start();
}
});
try {
mp.setDataSource("http://programmerguru.com/android-tutorial/wp-content/uploads/2013/04/hosannatelugu.mp3");
} catch (Exception e) {
e.printStackTrace();
}
start.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp) {
try {
if(!prepared) {
mp.prepareAsync();
prepared = true;
} else {
mp.start();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
});
pause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp) {
mp.pause();
}
}
});
stop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp) {
mp.stop();
prepared = false;
}
}
});
}
}

#MRodrigues was right about media player states. But instead of calling release() after stop, Modify your code as below.
Currently,
try {
mp.setDataSource("http://programmerguru.com/android-tutorial/wp-content/uploads/2013/04/hosannatelugu.mp3");
mp.prepare();
} catch (Exception e) {
e.printStackTrace();
}
start.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.start();
}
});
modify to,
try {
mp.setDataSource("http://programmerguru.com/android-tutorial/wp-content/uploads/2013/04/hosannatelugu.mp3");
} catch (Exception e) {
e.printStackTrace();
}
start.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (!mp.isPlaying()) {
mp.prepare();
}
mp.start();
}
});

Get an error while i try to put Insterstitial Ads

i ask here because i can't put instertital ads in my app. I get like 20 errors when i put the code below the saved Instance.

this token
- Syntax error, insert ";" to complete FieldDeclaration
package lol.flashlight;
Then here:
ImageView Facebook = (ImageView) findViewById(R.id.imageView3);
Facebook.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
i get this errors:
Multiple markers at this line
- Syntax error, insert "}" to complete
MethodBody
- Syntax error, insert ")" to complete
Expression
- Syntax error, insert ";" to complete
Statement
- Syntax error, insert "}" to complete

...I get MORE errors
I tried to put it at the final but anyway i get these errors, what can i do?

your imports here are wrong, because they import from legacy admob:
import com.google.ads.Ad;
import com.google.ads.AdListener;
import com.google.ads.AdRequest;
import com.google.ads.AdRequest.ErrorCode;
import com.google.ads.InterstitialAd;
You have to import from .gms Google Play Services Admob:
import com.google.android.gms.ads.*
Also note that all the code below Toast.makeText(MainActivity.this, "Touch amumu's body to play a sound!", Toast.LENGTH_SHORT).show(); in your example is outside of any method (!) ..this is causing the dozens of compile errors. ==> move that code into some method

How can i put an OnClickListener to a Background?

*Hi, i have a flashlight app, but i can´t run it, idk why, i think that is the OnClickListener in Background.. maybe its wrong, or idk, i am newbie , sorry D:
Logcat: enter link description here (Nothing important i think)
I have other FlashLight and the Background OnClickListener is the difference between these apps.. But.. How can i put, that when i click The LAYOUT or BACKGROUND ( the same thing ) turn on flash ? :|
Here the code:*

Inside your onCreate, you can have a layout's onClickListener on your outermost layout as follows:
RelativeLayout layout=(RelativeLayout)findViewById(R.id.yourRelativeLayout);
layout.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v){
}
});
You might have to add android:clickable = true from xml or setClickable(true) from code.

media player pause is not working

On click of a linear layout I need to pause my streaming in the mediaplayer which is associated with a surface view.
But the player is not pausing.(I'm testing in emulator).
here is the code
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
Thread.setDefaultUncaughtExceptionHandler(onBlooey);
setContentView(R.layout.main);
surface = (TappableSurfaceView) findViewById(R.id.surface);
surface.addTapListener(onTap);
holder = surface.getHolder();
holder.addCallback(this);
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
topPanel = findViewById(R.id.top_panel);
bottomPanel = findViewById(R.id.bottom_panel);
timeline = (SeekBar) findViewById(R.id.timeline);
timeline.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
// TODO Auto-generated method stub
if (player != null) {
if (player.isPlaying()) {
player.seekTo(progress);
} else {
player.start();
player.seekTo(progress);
}
}
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
});
media = (ImageButton) findViewById(R.id.media);
media.setOnClickListener(onMedia);
seekbarTopPanel = (LinearLayout) findViewById(R.id.seekbarTopPanel);
playVideo();
clearPanels(true);
seekbarTopPanel.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
topPanel.setVisibility(View.VISIBLE);
if (player != null) {
System.out.println("in player pause");
player.pause();
}
}
});
}
public void surfaceCreated(SurfaceHolder holder) {
player.setDisplay(holder);
}
private void playVideo() {
try {
media.setEnabled(false);
if (player == null) {
System.out.println("media player created");
player = new MediaPlayer();
player.setScreenOnWhilePlaying(true);
} else {
player.stop();
player.reset();
}
// url="C:\\Users\\Sai Dinakar\\Downloads\\Relaxing Music & Beautiful Nature 6 1080p HD.mp3";
Uri url = Uri.parse("android.resource://" + getPackageName() + "/"
+ R.raw.nature);
// player.setDataSource(url);
player.setDataSource(getApplicationContext(), url);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setOnPreparedListener(this);
player.prepareAsync();
// player.setOnBufferingUpdateListener(this);
player.setOnCompletionListener(this);
VideoTimerHandler videoTimerHandler = new VideoTimerHandler();
videoTimerHandler.playVideoTimer();
} catch (Throwable t) {
Log.e(TAG, "Exception in media prep", t);
}
}
The issue is in oncreate -->seekbarTopPanel.setOnClickListener(new OnClickListener()
The on pause is getting called but still the video is not pausing.
