# Initialize third parties

### AdMob

If you want to support AdMob in your application you need to fill these infos In `local.properties` file :

```
# AdMob
admob_app_id_android=
admob_rewarded_ad_id_android=

admob_app_id_ios=
admob_rewarded_ad_id_ios=
```

You need to go on your AdMob account and create two applications: one for Android and one for iOS. Then create rewarded ads for both projects. Use these app ids and rewarded ads ids in `local.properties`.

#### Remove AdMob support

#### If you don't want to support AdMob you have to remove this line in the AndroidManifest.xml file: 

```
<meta-data 
android:name="com.google.android.gms.ads.APPLICATION_ID" 
android:value="${admobAppId}" />
```

Remove dependency in shared module (build.gradle file)

```
api(libs.play.services.ads)
```

Remove this line on AppInitializer#initialize and all code related to AdMob

```
initAdMob()
```

### Google Map

If you want to support Google Map fill the api key else just ignore.

```
# Google Map
google_map_api_key=
```

### RevenueCat

Fill your api keys in local.properties

```
# RevenueCat
revenuecat_api_key_android=
revenuecat_api_key_ios=
```

If you don't want to setup RevenueCat simply do not fill the api keys in this file and just don't call the paywall and RevenueCat apis, this should be working.

### Sentry

If you want to support Sentry fill the api key else just ignore.

```
# Sentry
sentry_dsn=
```

### PostHog

To setup PostHog you just need to add the host and api key after you created the project on PostHog.

```
# PostHog
posthog_api_key=
posthog_host=
```

### Google SignIn

To support Google login fill the web client id. You can find this value after you enabled Firebase Auth + Google auth:

<figure><img src="/files/EKKD1atGiqp281awasLX" alt="" width="563"><figcaption></figcaption></figure>

```
# Google Sign in
google_sign_in_web_client_id=
```

### AppKickstarter AI Backend Proxy

```
# AI Proxy
mobile_ai_api_hmac_secret_key=
