# Migrating to Amplify Android From AWS Mobile SDK
[Amplify Android](https://github.com/aws-amplify/amplify-android) simplifies integrating AWS services into Android apps, making it easier to add features like authentication, data storage, and real-time updates without lots of code. This user-friendly interface not only cuts down on complexity but also speeds up the development process.
With Amplify Android, developers get tools that make setup straightforward, provide detailed documentation, and support advanced capabilities like offline data sync and GraphQL. This means you can spend less time dealing with the technicalities of cloud integration and more time crafting engaging user experiences.
Choosing Amplify Android could lead to quicker development, plus applications that are both scalable and secure.

Notes:

* Drop-in Auth provided by `AWSMobileClient` is replaced with [Authenticator UI component](https://ui.docs.amplify.aws/android/connected-components/authenticator). Additionally, Authenticator UI component does not support social providers yet. You can track updates on it [here](https://github.com/aws-amplify/amplify-ui-android/issues/125).

* To manually refresh the ID and access tokens (such as in scenarios where you might need to ensure that you have the latest tokens, perhaps because of changes in permissions or other security-related updates) refer to [Amplify docs](_https://docs.amplify.aws/android/build-a-backend/auth/accessing-credentials/#force-refreshing-session_)

* Amplify Sign In's will handle token refreshing as long as the refresh token is valid. Amplify does not support refreshing tokens automatically through `federateToIdentityPool()`.

Notes:

* For recording events:

When migrating from the AWS SDK for Android to Amplify, you'll need to adjust your approach to handle user sessions, as the two libraries have different mechanisms for managing user authentication and session management.

* Use `Amplify.Analytics.recordEvent()` for recording Monetization event.

```
// Example:
val PURCHASE_EVENT_NAME = "_monetization.purchase"
val PURCHASE_EVENT_QUANTITY_METRIC = "_quantity"
val PURCHASE_EVENT_ITEM_PRICE_METRIC = "_item_price"
val PURCHASE_EVENT_PRODUCT_ID_ATTR = "_product_id"
val PURCHASE_EVENT_PRICE_FORMATTED_ATTR = "_item_price_formatted"
val PURCHASE_EVENT_STORE_ATTR = "_store"
val PURCHASE_EVENT_TRANSACTION_ID_ATTR = "_transaction_id"
val PURCHASE_EVENT_CURRENCY_ATTR = "_currency"

val event = AnalyticsEvent.builder()
.name(PURCHASE_EVENT_NAME)
.addProperty(PURCHASE_EVENT_PRODUCT_ID_ATTR, productId)
.addProperty(PURCHASE_EVENT_STORE_ATTR, store)
.addProperty(PURCHASE_EVENT_QUANTITY_METRIC, quantity)
.addProperty(PURCHASE_EVENT_PRICE_FORMATTED_ATTR, formattedItemPrice)
.addProperty(PURCHASE_EVENT_ITEM_PRICE_METRIC, itemPrice)
.addProperty(PURCHASE_EVENT_TRANSACTION_ID_ATTR, transactionId)
.addProperty(PURCHASE_EVENT_CURRENCY_ATTR, currency)
.build()
Amplify.Analytics.recordEvent(event)
```

* Amplify Analytics events have default configuration to flush out to the network every 30 seconds. This interval can be configured in `amplifyconfiguration.json.` Refer [Flush Events](https://docs.amplify.aws/android/build-a-backend/more-features/analytics/record-events/#flush-events) section in Amplify Documentation for more details.
* Limits applicable to ingestion of events for Amazon Pinpoint can be found [here](https://docs.aws.amazon.com/pinpoint/latest/developerguide/quotas.html#limits-events).
