Android Notification arrives only when device is usb debug attached

Question

I have exactly the same problem.Android Notifications triggered by pending intent works perfectly when device is attached with debugger but does not works after remove.The solution given in that problem does not works for me.

Code

public class MedicineReceiver extends BroadcastReceiver {

    private static int notificationId=0;
    private static int id=0;
    DataBase dataBase;

    public MedicineReceiver() {
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO: This method is called when the BroadcastReceiver is receiving
        // an Intent broadcast.
        //throw new UnsupportedOperationException("Not yet implemented");

        if(id!=intent.getIntExtra("ID",-1))
        {
            notificationId++;
            id=intent.getIntExtra("ID",-1);
        }

        dataBase=new DataBase(context);
        if(dataBase.isOkay(id+""))
        {


            Intent myIntent=new Intent(context,Medicine_ItemActivity.class);
            myIntent.putExtra("ID",intent.getIntExtra("ID",-1));
            PendingIntent pendingIntent=PendingIntent.getActivity(context,id,myIntent,PendingIntent.FLAG_ONE_SHOT);

            NotificationCompat.Builder mBuilder =
                    new NotificationCompat.Builder(context)
                            .setSmallIcon(R.mipmap.medicine)
                            .setContentTitle("ঔষধ ")
                            .setContentText(createText(intent))
                            .setAutoCancel(true)
                            .setLights(Color.RED, 3000, 3000)
                            .setVibrate(new long[]{1000,1000,1000})
                            .setContentIntent(pendingIntent);
            if (getBool(dataBase.getSound(id + ""))) {
                String source = dataBase.getSourcse(id + "");
                if(source.compareTo("DEFAULT")==0)
                {
                    Uri uri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
                    mBuilder.setSound(uri);
                }
                else
                {
                    mBuilder.setSound(getURI(source, context));
                }
            }

            NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
            mNotificationManager.notify(notificationId, mBuilder.build());
        }
    }

    Uri getURI(String  st,Context context)
    {
        File ringtoneFile = new File(st); //sd-card path/songname.mp3

        ContentValues content = new ContentValues();

        content.put(MediaStore.Audio.Media.IS_MUSIC, false);


        Uri Ringtone1 = Uri.parse(st);
        //Insert it into the database
        Log.i("TAG", "the absolute path of the file is :"+
                ringtoneFile.getAbsolutePath());
        Uri uri = MediaStore.Audio.Media.getContentUriForPath(

        context.getContentResolver().delete(uri, MediaStore.MediaColumns.DATA + "=\"" + ringtoneFile.getAbsolutePath() + "\"",

        System.out.println("uri=="+uri);

        return newUri;
    }

    String getFileName(String  st)
    {
        String []pathFile=st.split("/");
        return pathFile[pathFile.length-1];
    }
    boolean getBool(String st)
    {
        if(st.compareTo("true")==0)
        {
            return  true;
        }
        else
        {
            return  false;
        }
    }
    String createText(Intent intent)
    {
        String text="আপনার "+dataBase.getName(id+"")+" ঔষধটি ";
        if(intent.getStringExtra("MORNING")!=null)
        {
            text+="(সকালে";
        }
        if(intent.getStringExtra("NOON")!=null)
        {
            text+=",দুপুরে";
        }
        if(intent.getStringExtra("NIGHT")!=null)
        {
            text+=",রাতে";
        }
        text+=")খাওয়ার সময় হয়েছে।";
        return text;
