android - Notification in Service on isolated process throws NPE -


i nullpointer, every time try send notification service runs on isolted service.

the exception:

    java.lang.nullpointerexception         @ android.app.notificationmanager.notify(notificationmanager.java:136)         @ android.app.notificationmanager.notify(notificationmanager.java:109)         @ de.nwo.client.modules.service.nwoservice.createorupdatenotification(nwoservice.java:66)         @ de.nwo.client.modules.service.nwoservice.access$000(nwoservice.java:23)         @ de.nwo.client.modules.service.nwoservice$1.run(nwoservice.java:47)         @ android.os.handler.handlecallback(handler.java:730)         @ android.os.handler.dispatchmessage(handler.java:92)         @ android.os.looper.loop(looper.java:137)         @ android.app.activitythread.main(activitythread.java:5103)         @ java.lang.reflect.method.invokenative(native method)         @ java.lang.reflect.method.invoke(method.java:525)         @ com.android.internal.os.zygoteinit$methodandargscaller.run(zygoteinit.java:737)         @ com.android.internal.os.zygoteinit.main(zygoteinit.java:553)         @ dalvik.system.nativestart.main(native method)

manifest declaration:

        <service         android:name=".modules.service.nwoservice"         android:exported="false"         android:isolatedprocess="true"         android:process=":nwoservice"/>

the service implementation:

    @override public int onstartcommand(intent intent, int flags, int startid) {     log.d(service_tag,"started!");     startlogging();     return service.start_sticky; }  private void startlogging() {     handler handler = new handler();     handler.postdelayed(new runnable() {         @override         public void run() {             createorupdatenotification();             startlogging();         }     },3000); }  private void createorupdatenotification(){     notificationcompat.builder builder = new notificationcompat.builder(this);     builder             .setsmallicon(r.mipmap.ic_launcher)             .setpriority(notification.priority_max)             .setcolor(color.green)             .setongoing(true)             .setcontenttext(string.valueof(++increment))             .setcontenttitle("nwo");     notificationmanager mnotificationmanager = (notificationmanager) getsystemservice(context.notification_service);     notification f = builder.build();     log.d(service_tag, "nm: " + mnotificationmanager + " , notification: " + f);     mnotificationmanager.notify(notificationid, f); //npe here }

if remove lines android:isolatedprocess="true" , android:process=":nwoservice" manfiset, works intended. know reason? why can't use notificationmanager isolated process?
