Question build the apk error notifications

When I build the apk with "com.unity.mobile.notifications": "2.0.0", everything works fine.

But when I build the apk after upgrading to "com.unity.mobile.notifications": "2.0.2" I get the following error

Note: G:\CR_Online\Temp\gradleOut\unityLibrary\src\main\java\com\unity3d\player\UnityPlayerActivity.java uses or overrides obsolete APIs. Note: For details, recompile with -Xlint:deprecation. Note: G:\CR_Online\Temp\gradleOut\unityLibrary\src\main\java\com\unity\androidnotifications\UnityNotificationManager.java uses unchecked or unsafe operations.

this error if you read through it is because your key manager key is not the proper format for unity graple. you need to go into the build settings - player settings navigate to the android publish settings select custom keystore and build a key for your app and then build. you can also do this through edit - project settings - player. none of the video's i have watched on building an oculus app explains this. but having been an adroid developer since 2010 and having built many android apps i realized i had this type of problem before.
