| `android.state` | string | This attribute represents the state the application has transitioned into at the occurrence of the event. [1] | `created` |  |
|

|
**[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` has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.
|

|
| 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. |  |
|
|
| `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. |  |
|
|
| `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. |  |
