## Prerequisites

*Performed by: Developer*

**App prerequisites**

* minSdkVersion of **23** or higher
* compileSdkVersion of 36 or higher
* The Google Mobile Ads (GMA) SDK must be integrated in your app
* An ad unit must already be in place which will be used for targeting

## Install the SDK

*Performed by: Developer*

Ensure your `android/build.gradle` (project-level) includes the required repositories:

```
allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' }
    }
}
```

**Note:** On Gradle 7+, use [Gradle Setup (Gradle 7+)](/gradle-setup/for-gradle-version-7-plus) instead — declare repositories in `settings.gradle` under `dependencyResolutionManagement` and remove the `allprojects` block. Use one approach, not both.

Open the `build.gradle` (Module: app) file and add:

```
dependencies {
    implementation("io.github.tapmind-tech:customadapter-ironsource:2.1.15")
    implementation("com.google.android.gms:play-services-ads:25.0.0")
}
```

## Configure your app

*Performed by: Developer*

Add your AdMob app ID to `AndroidManifest.xml`. Omitting this crashes the app on launch with `Missing application ID`.

```
<manifest>
  <application>
    <!-- Sample AdMob app ID: ca-app-pub-3940256099942544~3347511713 -->
    <meta-data
        android:name="com.google.android.gms.ads.APPLICATION_ID"
        android:value="YOUR_ADMOB_APP_ID"/>
  </application>
</manifest>
```

Replace `YOUR_ADMOB_APP_ID` with your AdMob app ID from the [AdMob web interface](https://support.google.com/admob/answer/7356431). While testing, you may use Google's sample app ID shown above.

## Configure Unity LevelPlay

*Performed by: Ad ops*

**Create the TapMind network:** Monetize → Setup → SDK Networks → Available Networks → Manage Networks → select **Custom Adapter** → enter network key **15c11cb1d** → Enter → Save. The network appears as **TapMind**.

**Set up instances:** Setup → Instances → select TapMind (Custom) → Add ad instance → select ad type →

```
Instance Name : provided by your account manager
eCPM / Rate   : provided by your account manager
```

**Note:** Enter the rate for each placement — it determines waterfall order. Add one instance per ad format to start.

## Verify integration

*Performed by: Developer*

After install and dashboard configuration:

1. Run your app in a **debug** build. TapMind's test mode is enabled automatically in debug builds and serves test ads at a high fill rate.
2. Request an ad through your mediation SDK as you normally would.
3. Confirm a TapMind ad fills. Check logs for the tag **`TapMindAdapter`**.
4. When verified, build in **release** mode for production — test mode is disabled automatically in release builds, and live ads serve.

**Note:** Test mode is automatic. It follows your build type: debug = test ads, release = live ads. There is no flag to enable or disable, and nothing to turn off before going live.

**Release build QA:** There is currently no documented release-safe test path to validate R8/ProGuard without serving live ads. Consumer ProGuard rules from the TapMind AAR are applied automatically when you integrate the published adapter packages.

## Troubleshooting

*Performed by: Developer*

| Symptom | Likely cause | Fix |
|---------|--------------|-----|
| No TapMind ad in production, but works in debug | Wrong/missing class string, or release-build stripping | Verify the class string matches the [Class & Network Key Registry](/reference/class-network-key-registry) exactly; TapMind AARs ship consumer ProGuard rules automatically |
| No fill at all | `placementName` mismatch (case/space) or wrong eCPM position | Re-check `placementName` exactly against the TapMind Dashboard Placement Name; confirm waterfall position |
| App crashes on launch | Missing AdMob app ID in manifest/Info.plist | Add the app-ID meta-data exactly as shown in **Configure your app** |
| Unity LevelPlay network never appears | Wrong network key | Use the canonical key from the Registry |

For anything else, contact your account manager with the log output and the tag **`TapMindAdapter`**.
