## Prerequisites

*Performed by: Developer*

**App prerequisites**

* See the [Compatibility Matrix](/reference/compatibility-matrix) for the minimum Android and compile SDK versions for this package.
* The Google Mobile Ads (GMA) SDK integrated in your app, with its app-ID meta-data (`com.google.android.gms.ads.APPLICATION_ID`) set in `AndroidManifest.xml`. Any app already serving Google ads has this set - if it's missing, the app crashes on launch (see [App crashes on launch](/reference/troubleshooting#app-crashes-on-launch)).
* An ad unit must already be in place which will be used for targeting

**Note:** **Custom Adapter (GMA Next-Gen SDK)** covers **AdMob**, **Google Ad Manager**, and **Unity LevelPlay** on **Android only**. Use the standard Custom Adapter (GMA SDK) for other mediations and platforms.

## 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-nextgen:2.0.0")
    implementation("com.google.android.libraries.ads.mobile.sdk:ads-mobile-sdk:1.3.0")
}
```


## 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 Marketplace → Add ad instance → select ad type →

```
Instance name : provided by your account manager
placementCODE : provided by your account manager
Mediation Group: Select your target mediation group
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*

Before diving into logs, confirm the LevelPlay network key against the [Class & Network Key Registry](/reference/class-network-key-registry), and `placementName` and eCPM/rate with your account manager.

See [Troubleshooting](/reference/troubleshooting) for common symptoms, mediation-specific fixes, release vs debug guidance, and escalation steps. Partner-specific verification steps are under **Verify integration** above.
