Android Service needs to run always Never pause or stop

I had overcome this issue  and my sample code is as follows   Add the below line in your Main Activity  here BackGroundClass is the service class You can create this class in New -  JavaClass  In this class  add the process  tasks  in which you needs to occur at background   For Convenience  first denote them with notification ringtone as background process    startService new Intent this  BackGroundClass  class      In the BackGroundClass  just include my codings and you may see the result   import android app Service  import android content Intent  import android media MediaPlayer  import android os IBinder  import android provider Settings  import android support annotation Nullable  import android widget Toast   public class BackgroundService  extends Service       private MediaPlayer player       Nullable      Override     public IBinder onBind Intent intent            return null         Override     public int onStartCommand Intent intent  int flags  int startId         player   MediaPlayer create this Settings System DEFAULT RINGTONE URI           player setLooping true            player start            return START STICKY          Override     public void onDestroy             super onDestroy             player stop              And in AndroidManifest xml  try to add this    lt service android name   BackgroundService   gt    Run the program  just open the application  you may find the notification alert at the background  Even  you may exit the application but still you might have hear the ringtone alert unless and until if you switched off the application or Uninstall the application  This denotes that the notification alert is at the background process  Like this you may add some process for background    Kind Attention  Please  Don t verify with TOAST as it will run only once even though it was at background process   Hope it will helps

You don t require broadcast receiver  If one would take some pain copy one of the api serviceconnection  from above example by Stephen Donecker and paste it in google you would get this  https   www concretepage com android android-local-bound-service-example-with-binder-and-serviceconnection

I found a simple and clear way of keeping the Service running always    This guy has explained it so clearly and have used a good algorithm  His approach is to send a Broadcast when the service is about to get killed and then use it to restart the service    You should check it out  http   fabcirablog weebly com blog creating-a-never-ending-background-service-in-android

In order to start a service in its own process  you must specify the following in the xml declaration    lt service   android name  WordService    android process   my process     android icon   drawable icon    android label   string service name     gt   lt  service gt     Here you can find a good tutorial that was really useful to me  http   www vogella com articles AndroidServices article html  Hope this helps

If you already have a service and want it to work all the time  you need to add 2 things    in the service itself   public int onStartCommand Intent intent  int flags  int startId        return START STICKY     In the manifest   android launchMode  singleTop     No need to add bind unless you need it in the service

You can implement startForeground for the service and even if it dies you can restart it by using START STICKY on startCommand    Not sure though this is the right implementation

A simple solution is to restart the service when the system stops it   I found this very simple implementation of this method   How to make android service unstoppable

Is it possible to run this service always as when the application pause and anything else    Yes    In the service onStartCommand method return START STICKY   public int onStartCommand Intent intent  int flags  int startId            return START STICKY     Start the service in the background using startService MyService  so that it always stays active regardless of the number of bound clients    Intent intent   new Intent this  PowerMeterService class   startService intent    Create the binder   public class MyBinder extends Binder           public MyService getService                     return MyService this               Define a service connection   private ServiceConnection m serviceConnection   new ServiceConnection             public void onServiceConnected ComponentName className  IBinder service                    m service     MyService MyBinder service  getService                       public void onServiceDisconnected ComponentName className                    m service   null                Bind to the service using bindService           Intent intent   new Intent this  MyService class           bindService intent  m serviceConnection  BIND AUTO CREATE    For your service you may want a notification to launch the appropriate activity once it has been closed   private void addNotification                create the notification         Notification Builder m notificationBuilder   new Notification Builder this                   setContentTitle getText R string service name                    setContentText getResources   getText R string service status monitor                    setSmallIcon R drawable notification small icon               create the pending intent and add to the notification         Intent intent   new Intent this  MyService class           PendingIntent pendingIntent   PendingIntent getActivity this  0  intent  0           m notificationBuilder setContentIntent pendingIntent               send the notification         m notificationManager notify NOTIFICATION ID  m notificationBuilder build        You need to modify the manifest to launch the activity in single top mode             android launchMode  singleTop   Note that if the system needs the resources and your service is not very active it may be killed  If this is unacceptable bring the service to the foreground using startForeground           startForeground NOTIFICATION ID  m notificationBuilder build
