I made notification and I wanted to send the notification when the app is destroyed, so I put the notification inside a BroadcaseReceiver that is the inside onStartCommand method of service, and I make it executes onReceive when ACTION_TIME_CHANGED, however, the onStartCommand is executed, but onReceive() is not.
public class MyService extends Service {
NotificationManager notificationManager;
Notification.Builder notification;
#Override
public void onCreate() {
super.onCreate();
Toast.makeText(getApplicationContext(),"Service started",Toast.LENGTH_LONG).show();
}
#RequiresApi(api = Build.VERSION_CODES.O)
#Override
public int onStartCommand(#Nullable Intent intent, int flags, int startId) {
super.onStartCommand(intent, flags, startId);
Toast.makeText(getApplicationContext(),"Time is changed",Toast.LENGTH_LONG).show();
init_notification();
BroadcastReceiver receiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
Toast.makeText(context,"Time is changed",Toast.LENGTH_LONG).show();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
notificationManager.notify(NOTIFICATION_ID,notification.build());
}
}
};
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(Intent.ACTION_AIRPLANE_MODE_CHANGED);
registerReceiver(receiver,intentFilter);
return START_STICKY;
}
}
Modify your MyService class like this and let me know if it works.
public class MyService extends Service {
NotificationManager notificationManager;
Notification.Builder notification;
private BroadcastReceiver receiver;
#RequiresApi(api = Build.VERSION_CODES.O)
#Override
public void onCreate() {
super.onCreate();
init_notification();
receiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
Toast.makeText(context,"Time is changed",Toast.LENGTH_LONG).show();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
notificationManager.notify(NOTIFICATION_ID,notification.build());
}
}
};
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(ACTION_TIME_CHANGED);
registerReceiver(receiver, intentFilter);
Toast.makeText(getApplicationContext(),"Service started",Toast.LENGTH_LONG).show();
}
#Override
public int onStartCommand(#Nullable Intent intent, int flags, int startId) {
super.onStartCommand(intent, flags, startId);
Toast.makeText(getApplicationContext(),"Time is changed",Toast.LENGTH_LONG).show();
return START_STICKY;
}
#Override
public void onDestroy() {
super.onDestroy();
if(receiver != null)
unregisterReceiver(receiver);
}
}

I created an Android application to get all the call logs after the user ends the call. I used Broadcast Receiver to identify the changes then Run the service to get the information about the last call. But sometimes App is killed by the system after one or two days. I read the Broadcast Documentation, Android Service Documentation, and Android <OREO Restriction. Is there any way to keep the Call Broadcast Receiver all the time?
Is there any way to use work manager?
Is there any good approaches, please share here
Service class
public class CallReceiver extends BroadcastReceiver{
#RequiresApi(api = Build.VERSION_CODES.O)
#Override
public void onReceive(Context context, Intent intent) {
Intent startServiceIntent = new Intent(context, HammerService.class);
context.startForegroundService(startServiceIntent);
}
}
Service class
public class HammerService extends Service {
#Override
public void onCreate() {
super.onCreate();
IntentFilter ifilter = new IntentFilter();
ifilter.addAction(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED);
registerReceiver(receiver, ifilter);
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
String input = intent.getStringExtra("inputExtra");
Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this,
0, notificationIntent, 0);
Notification notification = new NotificationCompat.Builder(this, CHANNEL_ID)
.setContentTitle("Hammer Service")
.setContentText(input)
.setSmallIcon(R.drawable.ic_android)
.setContentIntent(pendingIntent)
.build();
startForeground(1, notification);
//do heavy work on a background thread
//stopSelf();
return START_NOT_STICKY;
}
#Override
public void onDestroy() {
super.onDestroy();
unregisterReceiver(receiver);
}
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
private final BroadcastReceiver receiver = new BroadcastReceiver() {
#Override
public void onReceive(final Context context, final Intent intent) {
String action = intent.getAction();
if(action.equals("android.provider.Telephony.SMS_RECEIVED")){
//action for sms received
}
else if(action.equals(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED)){
runfirstTime(context,intent);
}
}
};
I am using a service to start the mediaplayer as soon as the notification is shown and then stop the service when the action button is pressed. The service starts fine. But the service doesn't stop on clicking the action button.
This is my notification builder
public NotificationCompat.Builder getReminderNotification(String title,String message,PendingIntent intent1){
return new NotificationCompat.Builder(getApplicationContext(),reminderChannelID)
.setContentTitle(title)
.setContentText(message)
.setSmallIcon(R.drawable.ic_medicine)
.setColor(getResources().getColor(R.color.colorPrimary))
.setOngoing(true)
.addAction(R.drawable.ic_arrow_back,"OK",intent1);
}
public void cancelNotification() {
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.cancel(1); // Notification ID to cancel
}
public void startMyService(){
startService(new Intent(this, TimerService.class));
}
public void stopMyService(){
stopService(new Intent(this,TimerService.class));
}
This is my reminder receiver:
public class ReminderReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
NotificationHelper notificationHelper = new NotificationHelper(context);
Intent newIntent = new Intent(context,DismissReminderReceiver.class);
newIntent.putExtra("action","stop");
PendingIntent intent1 = PendingIntent.getBroadcast(context,0,newIntent,0);
Bundle extras = intent.getExtras();
String title=extras.getString("title");
String message=extras.getString("message");
NotificationCompat.Builder builder = notificationHelper.getReminderNotification(title, message,intent1);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
context.startForegroundService(new Intent(context.getApplicationContext(),TimerService.class));
}else {
notificationHelper.startMyService();
}
notificationHelper.getManager().notify(1, builder.build());
}}
This is my code to dismiss the notification
public class DismissReminderReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
System.out.println("Here");
Bundle extras = intent.getExtras();
String action = extras.getString("action");
System.out.println(action);
if (action.equals("stop")) {
NotificationHelper notificationHelper = new NotificationHelper(context);
notificationHelper.stopMyService();
notificationHelper.cancelNotification();
}
}}
And this is my service:
public class TimerService extends Service {
public Context context = this;
public Handler handler = null;
public Runnable runnable = null;
MediaPlayer mediaPlayer;public TimerService(){}
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
System.out.println("Service Started");
mediaPlayer=MediaPlayer.create(context, Settings.System.DEFAULT_RINGTONE_URI);
handler = new Handler();
runnable = new Runnable() {
#Override
public void run() {
mediaPlayer.start();
}
};
handler.postDelayed(runnable,0);
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
return super.onStartCommand(intent, flags, startId);
}
#Override
public void onDestroy() {
handler.removeCallbacks(runnable);
mediaPlayer.stop();
}}
I also don't see where you register the receiver - if you're doing it in the manifest, make sure it's there with a matching action (and the receiver stanza is there to begin with).
so i am trying to create a battery statistics android app but neither i'm able to receive broadcast using broadcastmanager cos its not available for android oreo and nor my service is running on background for more than a few minutes.
my question is how do i receive battery broadcasts like plug,unplug,level..... in background on android oreo api 26+
i run the service from the activity on destroy
/////my service code/////
public class bservice extends Service {
#Override
public void onCreate() {
super.onCreate();
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
IntentFilter ifl = new IntentFilter();
registerReceiver(bcr,new IntentFilter(Intent.ACTION_POWER_DISCONNECTED));
registerReceiver(bcr,new IntentFilter(Intent.ACTION_POWER_CONNECTED));
registerReceiver(bcr,new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
registerReceiver(bcr,new IntentFilter(Intent.ACTION_SCREEN_OFF));
registerReceiver(bcr,new IntentFilter(Intent.ACTION_SCREEN_ON));
registerReceiver(bcr,ifl);
new Thread(new Runnable() {
#Override
public void run() {
try {
Thread.sleep(10000);
update();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}).start();
Log.d("msg","running in background 1");
return Service.START_STICKY;
}
#Nullable
#Override

return null;
}
private final BroadcastReceiver bcr = new BroadcastReceiver() {
#Override

Log.d("msg","running in background 2");
}
};
#Override
public void onDestroy() {
super.onDestroy();
//unregisterReceiver(bcr);
Log.d("msg","service destroyed");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
startForegroundService(new Intent(this,bservice.class));
Log.d("msg","serv restarted");
}
}
void update()
{.......... my updating code
updaten(pct,cc,isCharging,isCharging);
}
Notification notification;
NotificationManager notificationManager;
void updaten(float pct,float cc,boolean a,boolean ot)
{.........my notification update code
notificationManager.notify(id, notification);
}
}
}
Use JobIntentService instead of Service and then register broadcast receiver dynamically from service.
https://developer.android.com/reference/android/support/v4/app/JobIntentService.html
I want to start service in BroadcastReceiver (BOOT_COMPLETED) and make Notification from it.
Like this:
public class AutoLoad extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent arg1) {
Intent i = new Intent(context, MyService.class);
i.putExtra("screen_state", false);
context.startService(i);
}
}
public class MyService extends Service {
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Notification notification = new
NotificationCompat.Builder(getApplicationContext()).setContentTitle("New mail from ").setContentText("Text")
.setSmallIcon(android.R.drawable.btn_plus).build(); // addAction
NotificationManager nm = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
nm.notify(0, notification);
return Service.START_STICKY;
}
#Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
But no notification I can see. Please help!
You will need an Activity and run it at least once in order to be able to register to BOOT_COMPLETED intents.
I have a service to show notification at a specific time and one broadcastreceiver for starting this service. When the app is started, the service is started and shows notification and shows the service in app running on the device, but sometimes in the running app service is a Restarting and the message does not display.
my service code is:
public class NotificationService extends Service {
private boolean flag=false;
public static NotificationCompat.Builder mBuilder;
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Timer timer=new Timer();
final Context context=getApplicationContext();
timer.scheduleAtFixedRate(new TimerTask() {
#Override
public void run() {
if(CheckTime()){
//Intent intent = new Intent(context, NotificationReciver.class);
//sendBroadcast(intent);
showNotification();
}
}
},0,(1000*60));
return START_NOT_STICKY;
}
private boolean CheckTime(){
final Context context=getBaseContext();
Calendar calendar=Calendar.getInstance();
int hour=calendar.get(Calendar.HOUR_OF_DAY);
int minute=calendar.get(Calendar.MINUTE);
if(hour==16 && minute==11){
return true;
}else {
return false;
}
}
private void showNotification() {
Context context=getApplicationContext();
Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Intent intent=new Intent(context, QuestionActivity.class);
PendingIntent pendingIntent=PendingIntent.getActivity(context,0,intent,0);
mBuilder = new NotificationCompat.Builder(context).
setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Feelinger")
.setContentText("How are you feeling today?")
.setSound(alarmSound)
.setContentIntent(pendingIntent)
.setAutoCancel(true)
.setVibrate(new long[]{300, 200, 200, 200});
android.app.NotificationManager mNotificationManager = (android.app.NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(100, mBuilder.build());
}
and BroadcastReceiver code is:
public class NotificationManager extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
context.startService(new Intent(context,NotificationService.class));
}
How to solve this problem?
Write inside service
#Override
public int onStartCommand (Intent intent, int flags, int startId)
{
return START_NOT_STICKY;
}
