The support library has been superseded by [AndroidX](/jetpack/androidx) which is part of [Jetpack](/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider [migrating](/jetpack/androidx/migrate) existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library [class\n| mappings](/jetpack/androidx/migrate/class-mappings).\n\n\n`\npublic\n\nfinal\n\nclass\nActivityLifecycleMonitorRegistry\n`\n\n\n`\n\nextends `[Object](https://developer.android.com/reference/java/lang/Object.html)`\n\n\n`\n\n`\n\n\n`\n\n|---|------------------------------------------------------------------------|\n| [java.lang.Object](https://developer.android.com/reference/java/lang/Object.html) ||\n| ↳ | android.support.test.runner.lifecycle.ActivityLifecycleMonitorRegistry |\n\n\u003cbr /\u003e\n\n*** ** * ** ***\n\nAn exposed registry instance to make it easy for callers to find the lifecycle monitor for their\napplication.\n\nSummary\n-------\n\n| ### Public methods ||\n|-----------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| ` static `[ActivityLifecycleMonitor](/reference/android/support/test/runner/lifecycle/ActivityLifecycleMonitor) | ` `[getInstance](/reference/android/support/test/runner/lifecycle/ActivityLifecycleMonitorRegistry#getInstance())`() ` Returns the ActivityLifecycleMonitor. |\n| ` static void` | ` `[registerInstance](/reference/android/support/test/runner/lifecycle/ActivityLifecycleMonitorRegistry#registerInstance(android.support.test.runner.lifecycle.ActivityLifecycleMonitor))`(`[ActivityLifecycleMonitor](/reference/android/support/test/runner/lifecycle/ActivityLifecycleMonitor)` monitor) ` Stores a lifecycle monitor in the registry. |\n\n| ### Inherited methods |\n|-----------------------|---|\n| From class ` `[java.lang.Object](https://developer.android.com/reference/java/lang/Object.html)` ` |-------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------| | ` `[Object](https://developer.android.com/reference/java/lang/Object.html) | ` clone() ` | | ` boolean` | ` equals(`[Object](https://developer.android.com/reference/java/lang/Object.html)` arg0) ` | | ` void` | ` finalize() ` | | ` final `[Class](https://developer.android.com/reference/java/lang/Class.html)`\u003c?\u003e` | ` getClass() ` | | ` int` | ` hashCode() ` | | ` final void` | ` notify() ` | | ` final void` | ` notifyAll() ` | | ` `[String](https://developer.android.com/reference/java/lang/String.html) | ` toString() ` | | ` final void` | ` wait(long arg0, int arg1) ` | | ` final void` | ` wait(long arg0) ` | | ` final void` | ` wait() ` | ||\n\nPublic methods\n--------------\n\n### getInstance\n\n```\nActivityLifecycleMonitor getInstance ()\n```\n\nReturns the ActivityLifecycleMonitor.\n\nThis monitor is not guaranteed to be present under all instrumentations.\n\n\u003cbr /\u003e\n\n| Returns ||\n|-------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------|\n| [ActivityLifecycleMonitor](/reference/android/support/test/runner/lifecycle/ActivityLifecycleMonitor) | ActivityLifecycleMonitor the monitor for this application. \u003cbr /\u003e |\n\n| Throws ||\n|-------------------------------------------------------------------------------------------------------|------------------------------------|\n| [IllegalStateException](https://developer.android.com/reference/java/lang/IllegalStateException.html) | if no monitor has been registered. |\n\n### registerInstance\n\n```\nvoid registerInstance (ActivityLifecycleMonitor monitor)\n```\n\nStores a lifecycle monitor in the registry.\n\nThis is a global registry - so be aware of the impact of calling this method!\n\n\u003cbr /\u003e\n\n| Parameters ||\n|-----------|-------------------------------------------------------------------------------------------------------------|\n| `monitor` | `ActivityLifecycleMonitor`: the monitor for this application.
