I'm beginner in android development and tried to create a simple mediaplayer app which plays media from local source.
But it's crashing when i try to open it.
This is my java code.
package com.example.media;
import androidx.appcompat.app.AppCompatActivity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.SeekBar;
public class MainActivity extends AppCompatActivity {
Button play,pause;
SeekBar s;
MediaPlayer m;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
m=MediaPlayer.create(this,R.raw.live);
play=findViewById(R.id.button3);
pause=findViewById(R.id.button4);
s.findViewById(R.id.seekBar);
s.setMax(m.getDuration());
s.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
if(fromUser)m.seekTo(progress);
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
play.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
m.start();
}
});
pause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
m.pause();
}
});
}
}
You need to initialize the seekbar object instead of calling the findViewById method.
So just replace the dot with equal sign :
s=findViewById(R.id.seekBar);
I am making an app which if you click on a button an audio will play but the audio is not playing in last two buttons and can you also please tell me how can I stop the audio if I click on the audio button again ?? Here's The Full Code. Thanks in Advance. It's in gdsph_btn & aspamm_btn
package com.agrimplayz.radhasoamipaath;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
private Button rrjk_btn, gdsph_btn, aspamm, stop_btn;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
rrjk_btn = findViewById(R.id.rrjk_btn);
final MediaPlayer mediaPlayer = MediaPlayer.create(this,R.raw.radhasoami_rakshak_jeev_ke);
rrjk_btn.setOnClickListener(new View.OnClickListener() {
int counter = 0;
#Override
public void onClick(View v) {
if(counter == 2)
mediaPlayer.pause();
mediaPlayer.start();
gdsph_btn = findViewById(R.id.gdsph_btn);
MediaPlayer mediaPlayer = MediaPlayer.create(MainActivity.this,
R.raw.guru_dhara_sheesh_par_haath);
final MediaPlayer finalMediaPlayer1 = mediaPlayer;
gdsph_btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
finalMediaPlayer1.start();
}
});
aspamm = findViewById(R.id.gdsph_btn);
mediaPlayer = MediaPlayer.create(MainActivity.this,
R.raw.ae_satguru_pita_aur_malik_mere);
final MediaPlayer finalMediaPlayer = mediaPlayer;
aspamm.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
finalMediaPlayer.start();
}
});
}
});
}
}
you can try this code:
public class MainActivity extends AppCompatActivity {
private Button rrjk_btn, gdsph_btn, aspamm, stop_btn;
int counter = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MediaPlayer mediaPlayer1 = MediaPlayer.create(this, R.raw.radhasoami_rakshak_jeev_ke);
rrjk_btn = findViewById(R.id.rrjk_btn);
rrjk_btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (counter == 2)
{
mediaPlayer1.pause();
}
mediaPlayer1.start();
counter++;
}
});
//
MediaPlayer mediaPlayer2 = MediaPlayer.create(MainActivity.this, R.raw.guru_dhara_sheesh_par_haath);
gdsph_btn = findViewById(R.id.gdsph_btn);
gdsph_btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mediaPlayer2.start();
}
});
//
aspamm = findViewById(R.id.gdsph_btn);
MediaPlayer mediaPlayer3 = MediaPlayer.create(MainActivity.this, R.raw.ae_satguru_pita_aur_malik_mere);
aspamm.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mediaPlayer3.start();
}
});
}
}
I have an activity named Player Activity in which I am streaming music with the help of MediaPlayer API. Whenever my activity is created a notification is displayed which has some basic control of the music player.
So when I tap on my notification it jumps back to the Player Activity, but the state of the activity is lost.
Before tapping on notification :
After tapping on notification :
Here is the code of my notification's Pending Intent
Intent notifyIntent = new Intent(context, PlayerActivity.class);
notifyIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
notifyIntent.setAction("android.intent.action.MAIN");
notifyIntent.addCategory("android.intent.category.LAUNCHER");
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, notifyIntent, PendingIntent.FLAG_UPDATE_CURRENT);

Thanks in advance. Pardon me if the explanation is not clear, because if i might have right words to explain it, I would have googled it.
Add this to your PlayerActivity activity in manifest :
android:launchMode="singleTask"
And use these flags in the intent for pendingintent :
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
I have radio app which streams online radio. But it don't work on background i.e when i press home button phone automatically shut it down. how do i make it run on background.

All above is my main Activity. please look and give suggestion.Thanks in advance.
I'm trying to make a sort of soundboard app in Android Studio. For now I have three buttons: 2 of them play specific audio files and the other one stops the audio. Everything works except if you play one audio file while another one is going already they both play at the same time and the stop button no longer works on either of them. You have to exit the app. I cannot figure out how to get the first file to quit before playing the second. Here is my code so far:
package com.something.example.com;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnCompletionListener;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
public class MainActivity extends ActionBarActivity {
private Button startLie, startTruth,
stopScan;
private MediaPlayer play;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startLie = (Button) findViewById(R.id.startlie);
startLie.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
play = MediaPlayer.create(MainActivity.this, R.raw.lie_detector);
play.start();
play.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer play) {
play.release();
}
});
}
});
stopScan = (Button) findViewById(R.id.stopScan);
stopScan.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
play.stop();
};
});
startTruth = (Button) findViewById(R.id.starttruth);
startTruth.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
play = MediaPlayer.create(MainActivity.this, R.raw.truth_detector);
play.start();
play.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer play) {
play.release();
}
});
}
});
So I seem to have been able to finally get this to work. I basically created a stopPlaying function (placed at the end of my file. and then called it every time before the audio files play. Here's the code again, and this time with a couple more buttons.
package com.something.example;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnCompletionListener;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;

import android.view.View;
import android.widget.Button;
public class MainActivity extends ActionBarActivity {
private Button startLie, startTruth,
startIdiot, startGenius, stopScan;
private MediaPlayer play;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startLie = (Button) findViewById(R.id.startlie);
startLie.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
stopPlaying();
play = MediaPlayer.create(MainActivity.this, R.raw.lie_detector);
play.start();
play.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer play) {
play.release();
}
});
}
});
stopScan = (Button) findViewById(R.id.stopScan);
stopScan.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
play.stop();
};
});
startTruth = (Button) findViewById(R.id.starttruth);
startTruth.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
stopPlaying();
play = MediaPlayer.create(MainActivity.this, R.raw.truth_detector);
play.start();
play.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer play) {
play.release();
}
});
}
});
startIdiot = (Button) findViewById(R.id.startidiot);
startIdiot.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
stopPlaying();
play = MediaPlayer.create(MainActivity.this, R.raw.idiot_detector);
play.start();
play.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer play) {
play.release();
}
});
}
});
startGenius = (Button) findViewById(R.id.startgenius);
startGenius.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
stopPlaying();
play = MediaPlayer.create(MainActivity.this, R.raw.genius_detector);
play.start();
play.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer play) {
play.release();
}
});
}
});
}
private void stopPlaying() {
if (play != null) {
play.stop();
play.release();
play = null;
}
}
