## Public constructors

### OnSubscriptionsChangedListener

Added in [API level 22](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public OnSubscriptionsChangedListener ()
```

Create an OnSubscriptionsChangedListener. For callers targeting `https://developer.android.com/reference/android/os/Build.VERSION_CODES#P` or earlier, this can only be called on a thread that already has a prepared Looper. Callers targeting Q or later should subsequently use `https://developer.android.com/reference/android/telephony/SubscriptionManager#addOnSubscriptionsChangedListener(java.util.concurrent.Executor,%20android.telephony.SubscriptionManager.OnSubscriptionsChangedListener)`. On OS versions prior to `https://developer.android.com/reference/android/os/Build.VERSION_CODES#VANILLA_ICE_CREAM` callers should assume that this call will fail if invoked on a thread that does not already have a prepared looper.
