SharedPreferences getSharedPreferences always returns previous value even it has been changed

I have a service that is started when the main activity starts. I call the Service using this code
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startService(new Intent(this, CheckService.class));
finish();
}
The Service has the following code:
public class CheckService extends Service {
private static final String TAG = "CheckService";
WakeLock wakeLock;
public CheckService() {
// TODO Auto-generated constructor stub
}
#Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
// TODO Auto-generated method stub
return START_STICKY;
}
#Override
public void onTaskRemoved(Intent rootIntent) {
// TODO Auto-generated method stub
Intent restartService = new Intent(getApplicationContext(),
this.getClass());
restartService.setPackage(getPackageName());
PendingIntent restartServicePI = PendingIntent.getService(
getApplicationContext(), 1, restartService,
PendingIntent.FLAG_ONE_SHOT);
//Restart the service once it has been killed android
AlarmManager alarmService = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
alarmService.set(AlarmManager.ELAPSED_REALTIME, SystemClock.elapsedRealtime() + 100, restartServicePI);
}
#Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
PowerManager pm = (PowerManager) getSystemService(this.POWER_SERVICE);
wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "DoNotSleep");
Log.e("Checker", "Service Created");
Timer myTimer = new Timer();
myTimer.schedule(new TimerTask() {
#Override
public void run() {
check_pref();
}
}, 0, 5000);
}
#Override
#Deprecated
public void onStart(Intent intent, int startId) {
// TODO Auto-generated method stub
super.onStart(intent, startId);
}
#Override
public void onDestroy() {
super.onDestroy();
sendBroadcast(new Intent("YouWillNeverKillMe"));
}
public void check_pref( ) {
Context con;
Log.e("check_pref", "Restarting");
try {
Process p = Runtime.getRuntime().exec("su");
DataOutputStream dos = new DataOutputStream(p.getOutputStream());
dos.writeBytes("chmod -R 0777 /data/data/com.my.project.app/\n");
dos.writeBytes("exit\n");
dos.flush();
dos.close();
p.waitFor();
p.destroy();
con = createPackageContext("com.my.project.app", 0);
SharedPreferences pref = con.getSharedPreferences("myprefs", 0);
String login_id = pref.getString("login", "");
System.out.println(login_id);
} catch (PackageManager.NameNotFoundException e)
{
Log.e("check_pref", e.toString());
}
catch (NullPointerException e){
e.printStackTrace();
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (InterruptedException e){
e.printStackTrace();
}
}
}
Every 5 seconds in my service runs method check_pref(), which checks login in another app (com.my.project.app) and prints it in Logcat. But even login has been changed it returns same value as previously. Only if I restart app it returns actual value. My device(android 5.1.1) is rooted and I allowed permissions for my app. Whats wrong with my code? How to make it always return the actual value, which located in /data/data/com.my.project.app/myprefs.xml ?
PS. I found a solution. I changed
SharedPreferences pref = con.getSharedPreferences("myprefs", 0);
to
SharedPreferences pref = con.getSharedPreferences("myprefs", MODE_MULTI_PROCESS); and it works now.

I changed
SharedPreferences pref = con.getSharedPreferences("myprefs", 0);
to
SharedPreferences pref = con.getSharedPreferences("myprefs", MODE_MULTI_PROCESS);
and it works now.

Android MediaPlayer cannot play files that contain '#' character in the file name using Uri.parse(path)

From what I can tell, the Uri.parse in my code is causing my MediaPlayer to fail on audio files with special characters in the filename, like "#" and others. I cannot figure out how to resolve this issue. I want to be able to use special characters in my filenames. Here is the code that I think is causing the issue:
public void playAudio(int media) {
try {
switch (media) {
case LOCAL_AUDIO:
/**
* TODO: Set the path variable to a local audio file path.
*/
if (path == "") {
// Tell the user to provide an audio file URL.
Toast
.makeText(
MediaPlayerDemo_Audio.mp,
"Please edit MediaPlayer_Audio Activity, "
+ "and set the path variable to your audio file path."
+ " Your audio file must be stored on sdcard.",
Toast.LENGTH_LONG).show();
}
mMediaPlayer = new MediaPlayer();
mMediaPlayer.setLooping(sound_loop);
mMediaPlayer.setDataSource(MediaPlayerDemo_Audio.mp, Uri.parse(path));
mMediaPlayer.prepare();
resetTimer();
startTimer();
mMediaPlayer.start();
Intent intent = new Intent(MediaPlayerDemo_Audio.PLAY_START);
sendBroadcast(intent);
break;
case RESOURCES_AUDIO:
/**
* TODO: Upload a audio file to res/raw folder and provide
* its resid in MediaPlayer.create() method.
*/
// mMediaPlayer = MediaPlayer.create(this, R.raw.test_cbr);
//mMediaPlayer.start();
}
//tx.setText(path);
} catch (Exception e) {
//Log.e(TAG, "error: " + e.getMessage(), e);
}
}
I am using MediaPlayerDemo_Audio.java to play sounds. As you can see from the above code, the mMediaPlayer.setDataSource(MediaPlayerDemo_Audio.mp, Uri.parse(path)); is calling the code to retrieve the file and media player, I think. I am not too skilled with android code yet. Here is the code for MediaPlayerDemo_Audio.java:
public class MediaPlayerDemo_Audio extends Activity {

play_pause.setOnClickListener(play_pause_clk);

}

How can I fix this issue so files can be parsed with special characters and played correctly in MediaPlayer? Am I missing something?

For local files, do not use Uri.parse(). Use Uri.fromFile(), passing in a File object pointing to the file in question. This should properly escape special characters like #.

MediaPlayer oncomplete listener in service not executing

I'm trying to create a service that will play music in the background, but when a song completes the nextone should be played but seems oncomplete listener is not called. Can anyone tell me where is the problem?
P.S. I don't get anything in logcat, and I dont get the log that should be shown when entering oncomplete listener.
Here is my code:

Alarm Manager Does Not Execute Repeatedly

I'm working on a group project for a class I'm taking and we cannot seem to figure out why our Alarm Manager does not fire intents repeatedly. We've picked through the source code from top to bottom and cannot seem to isolate the source of this issue.
Can anyone recommend a fix? (or perhaps a starting point?)
// Start service using AlarmManager
Calendar cal = Calendar.getInstance();
cal.add(Calendar.SECOND, 10);
Intent intent = new Intent(Rules.this, LMW.class);
PendingIntent pintent = PendingIntent.getService(Rules.this, 0, intent,
0);
AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
7 * 1000, pintent);
// Start 2nd service using AlarmManager
Intent intent2 = new Intent(Rules.this, KillTimer.class);
PendingIntent pintent2 = PendingIntent.getActivity(Rules.this, 0, intent2,
0);
AlarmManager alarm2 = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
120 * 1000, pintent2); // here

http://android-er.blogspot.in/2010/10/schedule-repeating-alarm.html

I have had a similar problem and perhaps it applies to you (hard to tell since the code you supplied is pretty hard to navigate).
My issue was that applying multiple intents to the manager that evaluated as equal overrode the previous applications of that intent. See http://developer.android.com/reference/android/content/Intent.html#filterEquals(android.content.Intent) for what I mean by equivalence.
As an example, I had a schedule that used the URI domy://thing, with extras that varied over each intent (I need to fire the same action with different arguments each time). Extras don't count in equivalence, so my alarms were getting overwritten by each other.
To get around this, I stored a queue of my alarms in a separate file and when one fired, popped the next off the top and put that in the manager. Maybe that'll help you.
UPDATE:
No examples publicly visible, but try this (Trigger is a simple object containing a URI and a time it needs to be fired, scheduleDb is a class that extends SQLiteOpenHelper):
/**
* Pops the next trigger off the queue, adds it to the alarm manager, and
* stores it in the DB in case we need to cancel it later.
*/
private void scheduleNextTrigger() {
Log.d(TAG, "Popping next trigger off queue");
Optional<Trigger> nextTrigger = scheduleDb.getNextTrigger();
if (!nextTrigger.isPresent()) {
Log.d(TAG, "Trigger queue is empty");
return;
}
Trigger trigger = nextTrigger.get();
Log.d(TAG, "Scheduling new trigger " + trigger);
PendingIntent operation = createPendingIntent(trigger);
long timestamp = trigger.getTimestamp();
// Ensure the next item is in the future
if (timestamp > clock.currentTimeMillis()) {
Log.v(TAG, "Found valid trigger: " + trigger);
alarmManager.set(AlarmManager.RTC_WAKEUP, timestamp, operation);
}
scheduleDb.setScheduledTrigger(trigger);
}
private PendingIntent createPendingIntent(Trigger trigger) {
// AlarmManager allows only one instance of each URI, and seems to randomly
// delete bundled URI extras, so we'll encode the triggered URI and place it
// on a constant stem
Uri triggerUri = Uri.parse(TRIGGER_URI + "?" + Uri.encode(trigger.getUri()));
Intent triggerIntent = new Intent(Intent.ACTION_VIEW, triggerUri);
triggerIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
Log.d(TAG, "Created trigger intent " + triggerIntent);
PendingIntent operation = PendingIntent.getService(this, 0, triggerIntent, 0);
return operation;
}
Hope that helps

How to detect the button press on a bluetooth headset

I have been trying to achieve this.
I have found this but they don't seem to help me:
http://android.amberfog.com/?p=415
Registering a headset button click with BroadcastReceiver in Android
https://issuetracker.google.com/issues/36910848
No matter what I try when I press the button on my head set the phone display the volume level control instead of being catch by my application and do something. Here is some of the code:
public class MediaButtonIntentReceiver extends BroadcastReceiver {
public MediaButtonIntentReceiver() {
super();
}
#Override
public void onReceive(Context context, Intent intent) {
Log.i("test1'", "test2");
String intentAction = intent.getAction();
if (!Intent.ACTION_MEDIA_BUTTON.equals(intentAction)) {
return;
}
KeyEvent event = (KeyEvent) intent
.getParcelableExtra(Intent.EXTRA_KEY_EVENT);
if (event == null) {
Log.i("test3'", "test4");
return;
}
int action = event.getAction();
if (action == KeyEvent.ACTION_DOWN) {
// do something
Log.i("test5'", "test6");
}
abortBroadcast();
}
}
public class MainActivity extends Activity {
private static final String TAG = "BTAudioActivity";
private MediaPlayer mPlayer = null;
private AudioManager amanager = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
amanager = (AudioManager) getSystemService(AUDIO_SERVICE);
amanager.setBluetoothScoOn(true);
amanager.startBluetoothSco();
amanager.setMode(2);
mPlayer = new MediaPlayer();
try {
mPlayer.setDataSource(new FileInputStream("/sdcard/sample.wav")
.getFD());
mPlayer.prepare();
mPlayer.setVolume(8,8);
mPlayer.start();
} catch (Exception e) {
Log.e(TAG, e.toString());
}
}
#Override
protected void onResume() {
// TODO Auto-generated method stub
MediaButtonIntentReceiver mMediaButtonReceiver = new MediaButtonIntentReceiver();
IntentFilter mediaFilter = new IntentFilter(Intent.ACTION_MEDIA_BUTTON);
mediaFilter.setPriority(1000);
registerReceiver(mMediaButtonReceiver, mediaFilter);
super.onResume();
}
#Override
public void onDestroy() {
mPlayer.stop();
amanager.setMode(2);
amanager.setBluetoothScoOn(false);
super.onDestroy();
}
}

Try registering in onCreate...
and add a power manager wake_lock using this
