 | Attribute  | Type | Description  | Examples  | Stability |
 |---|---|---|---|---|
 | `android.os.api_level` | string | Uniquely identifies the framework API revision offered by a version (`os.version`) of the android operating system. More information can be found [here](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels). | `33`; `32` | ![Experimental](https://img.shields.io/badge/-experimental-blue) |

+| `android.state` | string | This attribute represents the state the application has transitioned into at the occurrence of the event. [1] | `created` | ![Experimental](https://img.shields.io/badge/-experimental-blue) |
+
+**[1]:** The Android lifecycle states are defined in [Activity lifecycle callbacks](https://developer.android.com/guide/components/activities/activity-lifecycle#lc), and from which the `OS identifiers` are derived.
+
+`android.state` MUST be one of the following:
+
+| Value  | Description | Stability |
+|---|---|---|
+| `created` | Any time before Activity.onResume() or, if the app has no Activity, Context.startService() has been called in the app for the first time. | ![Experimental](https://img.shields.io/badge/-experimental-blue) |
+| `background` | Any time after Activity.onPause() or, if the app has no Activity, Context.stopService() has been called when the app was in the foreground state. | ![Experimental](https://img.shields.io/badge/-experimental-blue) |
+| `foreground` | Any time after Activity.onResume() or, if the app has no Activity, Context.startService() has been called when the app was in either the created or background states. | ![Experimental](https://img.shields.io/badge/-experimental-blue) |
