/**
* Base class for a service that device owner/profile owners can optionally have.
*
* <p>The system searches for it with an intent filter with the
* {@link DevicePolicyManager#ACTION_DEVICE_ADMIN_SERVICE} action, and tries to keep a bound
* connection as long as the hosting user is running, so that the device/profile owner is always
* considered to be in the foreground. This is useful to receive implicit broadcasts that
* can no longer be received by manifest receivers by apps targeting Android version
* {@link android.os.Build.VERSION_CODES#O}. Device/profile owners can use a runtime-registered
* broadcast receiver instead, and have a {@link DeviceAdminService} so that the process is always
* running.
*
* <p>Device/profile owners can use
* {@link android.content.pm.PackageManager#setComponentEnabledSetting(ComponentName, int, int)}
* to disable/enable its own service. For example, when a device/profile owner no longer needs
* to be in the foreground, it can (and should) disable its service.
*
* <p>The service must be protected with the permission
* {@link android.Manifest.permission#BIND_DEVICE_ADMIN}. Otherwise the system would ignore it.
*
* <p>When the owner process crashes, the service will be re-bound automatically after a
* back-off.
*
* <p>Note the process may still be killed if the system is under heavy memory pressure, in which
* case the process will be re-started later.
