IllegalStateException when launching InstallReferrerService (TagManager)

I have a problem with crashes of TagManager classes on Android 8. Here is the stack trace:
java.lang.RuntimeException: Unable to start receiver com.google.android.gms.tagmanager.InstallReferrerReceiver: java.lang.IllegalStateException: Not allowed to start service Intent { cmp=com.x.z/com.google.android.gms.tagmanager.InstallReferrerService (has extras) }: app is in background uid UidRecord{90347cf u0a65 RCVR idle procs:1 seq(0,0,0)}

For sure it is connected to Android 8.0: java.lang.IllegalStateException: Not allowed to start service Intent, but it looks I've configured the InstallReferrer according to Google documentation - https://developers.google.com/android/reference/com/google/android/gms/tagmanager/InstallReferrerReceiver

I have crash reports concerning only Android 8.0 and Samsung phones. I use com.google.android.gms:play-services-analytics:16.0.3
How to get rid of those crashes except removing the InstallReferrerReceiver code?

GcmBroadcastReceiver IllegalStateException: Not allowed to start service Intent

I am working on FCM Push notification in Android, where I am getting this exception:

You are running on Android 8.0+, with a targetSdkVersion of 26+. You cannot reliably call startService() from the background, such as from a GCM receiver. Instead, you should either:
Switch to startForegroundService() and use a foreground service, or
Switch to JobIntentService
In your particular case, the code that is calling startService() appears to be from Parse. You should see if there is an update to the Parse client that takes Android 8.0 into account.

Having hundreds of Oreo devices crashing due to this in past 24 hours. Seems to be affecting only on install. I am going to try and add android:permission="android.permission.BIND_JOB_SERVICE" to the 2 analytics services and see. Will report.
I Will be happy to provide more info if needed. Thanks

I recommend upgrading to play-services version 11.4.0. Add this in your Gradle file:
compile "com.google.android.gms:play-services-analytics:11.4.0
From the Play Services Revision 11.4.0, analytics section:
Added a new class AnalyticsJobService. This class provides compatibility support for Android O and is used by Analytics to upload data. No action is necessary to use this class, it’s added automatically as part of the Analytics package.
Deprecated the getContext() method of the AnalyticsService class.
Deprecated the CampaignTrackingService class.
and also you have to get permission.
android:permission="android.permission.BIND_JOB_SERVICE"
See below
https://developers.google.com/android/reference/com/google/android/gms/analytics/AnalyticsJobService

because CampaignTrackingService is now Deprecated
just remove this line from your manifest
<service android:name="com.google.android.gms.analytics.CampaignTrackingService"
android:exported="true"/>

COSU: Cannot find Activity any more after pin and then restart

I'm developing an App that can be Screen Pinned aka Corporate Owned Single Use aka Lock Task Mode.
If I pin it and then:
I close it (killing it) and then I launch it again
or after some code modification in android studio and then perform Run
restart after pin and unpin
I get the following error:

If I don't ever pin the app I can restart/upgrade&run it many times I want.
The nice thing is that is not even possible to uninstall the app because it has been configured as Device Owner, and so, it cannot be uninstalled unless a factory reset.
I dont understand how is possible that my activity disappears after an app restart. Can be something related to the intent category or action?
If anyone else encountered this behavior can tell me I will submit an issue to the bug report site.
Thanks.
EDIT 18/3
I think maybe this is happening because at a certain point, I kill the home category activity that in my case is the missing StartActivity in question, and it is not restarted even if I restart the app.

Found the solution in my COSU disable pinning implementation, I was doing:
PackageManager mPackageManager = getApplicationContext().getPackageManager();;
mPackageManager.setComponentEnabledSetting(
new ComponentName(getApplicationContext(), StartActivity.class),
PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
PackageManager.DONT_KILL_APP);
to disable the pinning on device boot, but this actually disable the specified component.
The correct implementation would be:
PackageManager mPackageManager = getApplicationContext().getPackageManager();;
mPackageManager.setComponentEnabledSetting(
new ComponentName(getApplicationContext(), StartActivity.class),
PackageManager.COMPONENT_ENABLED_STATE_DEFAULT,
PackageManager.DONT_KILL_APP);

Parse.com push notifications don't get to devices on background

Today I've implemented Parse.com Push service in my app.
I've noticed that the push notifications are being sent only when the app is open. I've also noticed that whenever I'm turning on my device there is a message says "Unfortunately, tof has stopped". The Logcat says Unable to start receiver.
The full Logcat:

I've tried to search on the Web but I didn't find any solution. I guess that it's something about the receiver background operation.
I need an answer as quickly as possible, so if you know a bit about Parse SDK and it's push topic so please, help me 'cause I need to solve this today.
This is my code.

I need major help right now!! Please help me!

Follow the steps below. This code works fine and run the receiver on background. The original answer link: https://www.parse.com/apps/quickstart#parse_push/android/native/existing

Have a look at this.

private static MainApplication instance = new MainApplication();
public MainApplication() {
instance = this;
}
public static Context getContext() {

}
#Override

super.onCreate();
Parse.initialize(this, " ", " ");
PushService.setDefaultPushCallback(this, FabulaClient.class);
PushService.subscribe(this, "Barca", FabulaClient.class);
ParseInstallation.getCurrentInstallation().saveInBackground();
}
}
taken from https://www.parse.com/questions/cannot-send-push-to-android-after-app-is-closed-until-screen-unlock

I've understood why I don't get the push notifications on background.
I've initialized parse sdk twice - on the OpenActivity.java and on ParseApplication.java. I've removed it from the OpenActivity.java and added this code line:
android:name=".ParseApplication"
To the application attribute on the AndroidManifest.xml and now I can get push notifications on background.
