Cannot stop and start service when I want

Cannot stop and start service when I want - android

That's my MainActivity.
package com.example.simeon.cookingbook.activities;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.KeyEvent;
import com.example.simeon.cookingbook.R;
import com.example.simeon.cookingbook.services.BackgroundMusic;
public class MainActivity extends AppCompatActivity {
Intent srv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.srv = new Intent(this, BackgroundMusic.class);
startService(srv);
}
#Override

super.onDestroy();
stopService(srv);
}
#Override

super.onPause();
stopService(srv);
}
#Override

}
#Override

super.onRestart();
startService(srv);
}
#Override

super.onResume();
startService(srv);
}
}
That's BackgroundMusic Service.
package com.example.simeon.cookingbook.services;
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
import com.example.simeon.cookingbook.R;
public class BackgroundMusic extends Service {
private static final String TAG = null;
public MediaPlayer player;
public IBinder onBind(Intent arg0) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
player = MediaPlayer.create(this, R.raw.background);
player.setLooping(true); // Set looping
player.setVolume(100,100);
}
public int onStartCommand(Intent intent, int flags, int startId) {
player.start();
return START_STICKY;
}
}
I have other activities and I want the music to be heard when my application is opened, but when it goes to background, I don't want music to continue playing. I tried with BaseActivityClass and have read a lot, but still no solution. Please help, thank you in advance.

When you are done using MediaPlayer you need to release it with the release() method. I guess the onDestroy() method of you Service is a good place for that:
public class BackgroundMusic extends Service {
private static final String TAG = null;
public MediaPlayer player;
public IBinder onBind(Intent arg0) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
player = MediaPlayer.create(this, R.raw.background);
player.setLooping(true); // Set looping
player.setVolume(100,100);
}
public int onStartCommand(Intent intent, int flags, int startId) {
player.start();
return START_STICKY;
}
public int onDestroy() {
player.release();
}
}

How to make service for Play Pause of music Player

Here is my code which is play song from the resources folder and now I am stuck with service so please help me.....
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mHandler=new Handler();
seekBar=findViewById(R.id.seekBar);
mp=MediaPlayer.create(MainActivity.this,R.raw.ed);
final int Duration=mp.getDuration();
Media Player Prepared Listener.....
mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
seekBar.setMax(mp.getDuration());
updateSeekBar();
mp.start();
}
});
Runnable Thread for Seekbar.....
runnable=new Runnable() {
#Override
public void run() {
updateSeekBar();
}
};
Phone State Listener for Incoming and Outgoing Calls.....
PhoneStateListener phoneStateListener = new PhoneStateListener() {
#Override
public void onCallStateChanged(int state, String incomingNumber) {
if (state == TelephonyManager.CALL_STATE_RINGING) {
mp.pause();
} else if(state == TelephonyManager.CALL_STATE_IDLE) {
mp.start();
} else if(state == TelephonyManager.CALL_STATE_OFFHOOK) {
mp.pause();
}
super.onCallStateChanged(state, incomingNumber);
}
};
TelephonyManager mgr = (TelephonyManager)
getSystemService(TELEPHONY_SERVICE);
if(mgr != null) {
mgr.listen(phoneStateListener,
PhoneStateListener.LISTEN_CALL_STATE);
}
}
Seek Bar Update Method....
private void updateSeekBar() {
seekBar.setProgress(mp.getCurrentPosition());
mHandler.postDelayed(runnable, 100);
}
}
Now, it's my service code.......
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.support.annotation.Nullable;
public class MyMusicService extends Service {
On Create method of service....
#Override
public void onCreate() {
super.onCreate();
}
On start method of service....
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
return super.onStartCommand(intent, flags, startId);
}
On Destroy method of service....
#Override
public void onDestroy() {
super.onDestroy();
}
Binder of Service.....
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
}

AsyncTask not getting excused after app is terminated?

I want perform some check continuously. I have defined AsyncTask as
follows,
new AsyncTask<String, Void, String>() {
#Override
protected void onPreExecute() {
Log.d(TAG, "onPreExecute()");
}
#Override
protected String doInBackground(String... params) {
sendData(array);
return null;
}
#Override
protected void onPostExecute(String res) { }
}.execute(userResponse);
But when I terminate the application then thread stops execution.

Service class demo :-
package com.example.My Application;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.widget.Toast;
public class MyService extends Service {
#Override
public IBinder onBind(Intent arg0) {
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
// Let it continue running until it is stopped.
Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
return START_STICKY;
}
#Override
public void onDestroy() {
super.onDestroy();
Toast.makeText(this, "Service Destroyed", Toast.LENGTH_LONG).show();
}
}

package com.example.My Application;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.content.Intent;
import android.view.View;
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

}
#Override
public boolean onCreateOptionsMenu(Menu menu) {

return true;
}
// Method to start the service

startService(new Intent(getBaseContext(), MyService.class));
}
// Method to stop the service
public void stopService(View view) {
stopService(new Intent(getBaseContext(), MyService.class));
}
}
Manifest :-
Add <service android:name=".MyService" />

Service Intent must be explicit

I'm trying to use service for a background music.
package com.example.neotavraham;
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
import android.util.Log;
public class PlayMusicService extends Service implements MediaPlayer.OnPreparedListener {
public static final String ACTION_PLAY = "com.example.neotavraham.PLAY";
MediaPlayer mMediaPlayer = null;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (intent.getAction().equals(ACTION_PLAY)) {
mMediaPlayer = MediaPlayer.create(this, R.raw.yedid_nefesh);
mMediaPlayer.setOnPreparedListener(this);
mMediaPlayer.prepareAsync(); // prepare async to not block main thread
}
return flags;
}
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
}
I call it from the MainActivity with the line: startService(new Intent(PlayMusicService.ACTION_PLAY));
and of course I added an intent-filter
<intent-filter>
<action android:name="com.example.neotavraham.PLAY"/>
</intent-filter>
I was looking for a fine solution in the internet but couldn't find one...what should I do?

Please call the service from intent and set the action of that intent like this:
Intent i = new Intent(this,PlayMusicService.class);
i.setAction("com.example.neotavraham.PLAY");
startService(i);
This code will work.
Background service for start media player
package com.example.neotavraham;
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
import android.util.Log;
public class PlayMusicService extends Service {
public static final String ACTION_PLAY = "com.example.neotavraham.PLAY";
MediaPlayer mMediaPlayer = null;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (intent.getAction().equals(ACTION_PLAY)) {
mMediaPlayer = MediaPlayer.create(this, R.raw.idil);
mMediaPlayer.setLooping(true); // Set looping
mMediaPlayer.setVolume(100,100);
mMediaPlayer.start();
}
return flags;
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onDestroy() {
mMediaPlayer.stop();
mMediaPlayer.release();
}
}
Thanks

In your activity do the following:
Intent i = new Intent(this,PlayMusicService.class);
i.putExtra("action","com.example.neotavraham.PLAY");
startService(i);
In your service do the following:
package com.example.neotavraham;
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
import android.util.Log;
public class PlayMusicService extends Service {
public static final String ACTION_PLAY = "com.example.neotavraham.PLAY";
MediaPlayer mMediaPlayer = null;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (intent.getStringExtra("action").equals(ACTION_PLAY)) {
mMediaPlayer = MediaPlayer.create(this, R.raw.yedid_nefesh);
mMediaPlayer = MediaPlayer.create(this, R.raw.idil);
mMediaPlayer.setLooping(true); // Set looping
mMediaPlayer.setVolume(100,100);
mMediaPlayer.start();
}
return flags;
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onDestroy() {
mMediaPlayer.stop();
mMediaPlayer.release();
}
}
In your manifiest do the following:
<service
android:name="com.example.neotavraham.PlayMusicService"
/>
This is the perfect code for your app. Hope this will work finally....

In Android, How can I avoid the onStart method from being deprecated?

I am having a problem with setting the onStart method in my app. It always has a strikethrough, saying "This method was deprecated in API level 5. I need onStart, not onStartCommand.
How can I resolve this?

public class Reminder_2 extends Activity {
String message;

#Override
protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_reminder_2);

getMenuInflater().inflate(R.menu.reminder, menu);
return true;
}
}

Use onStartCommand().
It you want to know more about how they change it, refer to google documentation like below.
// This is the old onStart method that will be called on the pre-2.0
// platform. On 2.0 or later we override onStartCommand() so this
// method will not be called.
#Override
public void onStart(Intent intent, int startId) {
handleStart(intent, startId);
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
handleStart(intent, startId);
return START_NOT_STICKY;
}

You can use like this with onStartCommand().
package htin.linnzaw.service;
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
import android.widget.Toast;
public class MyService extends Service
{
private MediaPlayer mediaplayer;
public MyService()
{
}
#Override
public IBinder onBind(Intent intent)
{
// TODO: Return the communication channel to the service.
throw new UnsupportedOperationException("Not yet implemented");
}
#Override
public void onCreate()
{
Toast.makeText(this, "Service created", Toast.LENGTH_SHORT).show();
mediaplayer = MediaPlayer.create(this, R.raw.eventually);
mediaplayer.setLooping(false);
}
#Override
public int onStartCommand(Intent intent, int flags, int startid)
{
Toast.makeText(this, "Service Started", Toast.LENGTH_SHORT).show();
mediaplayer.start();
return startid;
}
#Override
public void onDestroy()
{
Toast.makeText(this, "Service stopped", Toast.LENGTH_SHORT).show();
mediaplayer.stop();
}
}
