I am new to android development.I created an audio player app for playing songs from SD card,its working fine and song is being played but when I click next button, song doesn't change and same track keeps playing.Button is clickable but song doesn't change on clicking it.How do I fix it ? any kind of help is appreciated,thanks.

try {
currentPosition=currentPosition+1;
playSong(path + songs.get(currentPosition));
} catch (IOException ex) {

}
}
Try this code :
public void next() {
ImageButton btnNext = (ImageButton) findViewById(R.id.btnNext);
btnNext.setOnClickListener(
new View.OnClickListener() {
public void onClick(View view) {
temp = temp + 1;
try {
playSong(mAudioPath[temp]);
} catch (Exception er) {
er.printStackTrace();
}
}
}
);
}
Dont forget to declare next() method in playsong()

Need to pick another random track after stopping the previous one by clicking "stop" button
I'm playing a random track by clicking "play" button, stop it by clicking "stop" and then i need to randomize again, in other words, to pick another track.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button play36 = (Button) findViewById(R.id.threesix);
Button stop = (Button) findViewById(R.id.stop);
String[] listOfFiles = new String[0];
try {
listOfFiles = getAssets().list("");
final List<String> musicOnlyList = new ArrayList<>();
for (int i = 0; i < listOfFiles.length; i++) {
if (getExtension(listOfFiles[i]).equals("mp3"))
musicOnlyList.add(listOfFiles[i]);
}
final MediaPlayer mediaPlayer = new MediaPlayer();
play36.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int itemIndex = new Random().nextInt(musicOnlyList.size());
String file = musicOnlyList.get(itemIndex);
AssetFileDescriptor afd = null;
try {
afd = getAssets().openFd(file);
mediaPlayer.reset();
mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
mediaPlayer.prepare();
} catch (IOException e) {
e.printStackTrace();
}
mediaPlayer.start();
}
});
stop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mediaPlayer.stop();
mediaPlayer.reset();
}
});
} catch (IOException e) {
e.printStackTrace();
}
In this case i get the same track everytime i start and stop player, but need to randomize everytime by clicking "play" button
You need to pick a new random number inside the listener of play36:
Button play36 = (Button)findViewById(R.id.threesix);
Button stop = (Button)findViewById(R.id.stop);
String[] listOfFiles = new String[0];
try {
listOfFiles = getAssets().list("");
final List<String> musicOnlyList = new ArrayList<>();
for(int i = 0; i < listOfFiles.length; i++){
if (getExtension(listOfFiles[i]).equals("mp3"))
musicOnlyList.add(listOfFiles[i]);
}
final MediaPlayer mediaPlayer = new MediaPlayer();
play36.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int itemIndex = new Random().nextInt(musicOnlyList.size());
String file = musicOnlyList.get(itemIndex);
AssetFileDescriptor afd = null;
try {
afd = getAssets().openFd(file);
mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
mediaPlayer.prepare();
} catch (IOException e) {
e.printStackTrace();
}
mediaPlayer.start();
}
});
stop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mediaPlayer.stop();
try {
mediaPlayer.prepare();
} catch (IOException e) {
e.printStackTrace();
}
}
});
} catch (IOException e) {
e.printStackTrace();

New Activity UI load but does not respond, After running onStop() which trigger submit()
List View with the checkbox is bound by a custom adapter. On touch of the Submit button, an intent is triggered which takes me to HomeActivity and onStop() method is triggered which in return call submit method. All submit method is created under a new thread which interfere with UI.

Just use

and remove finish()

Make sure you have the same name as property in your service and android parameters, for example request.addProperty("name",name) in the WebService public class Login(String name)
