# Migrate v1 to v2

> Migration guide - v1 to v2

Version 2.0.0 introduced some breaking changes which warranted this short guide.

### 1. Update AndroidManifest.xml

Before version 2.0.0 it was required to have the following metadata inside the application tag in the `AndroidManifest.xml`:

```xml theme={null}
<meta-data
    android:name="com.google.android.gms.ads.APPLICATION_ID"
    android:value="ca-app-pub-3940256099942544~3347511713"/>
```

This can now be removed. This ID will be moved in the next step.

### 2. Update SDK Initialisation

Update to the new SDK configuration API which now requires the Google application ID as a parameter:

```kotlin theme={null}
val configuration = CIMobileAdsConfiguration.Builder(
    publisherId = "<PUBLISHER-ID>",
    googleId = "ca-app-pub-3940256099942544~3347511713" // New required parameter
)
.setDebugFeature(true)
.enableAppOpen("<PLACEMENT-ID>") // only required if using App Open ads
.build()
```

### 3. Interstitial ads

If your application uses Interstitial ads, the `CIInterstitialAd` API no longer requires the `context` parameter, so this can be removed:

```kotlin theme={null}
val interstitial = CIInterstitialAd(
    placementID = "<PLACEMENT-ID>",
    eventListener = eventListener,
    pageUrl = "https://example.com/sport"
)
```
