AppLovin

Prerequisites

Performed by: Developer

App prerequisites

minSdkVersion of «MIN-ANDROID» (26) or higher
iOS «MIN-IOS» (18.0) or higher — confirm with your account manager
An ad unit must already be in place which will be used for targeting

Install the SDK

Performed by: Developer

Install the TapMind AppLovin extension:

Extension → Extension Manager → Install from File → select the TapMind extension ZIP → Enable.

Pin a tagged release ZIP rather than archive/refs/heads/main.zip.

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. While testing, you may use Google's sample app ID shown above.

Add GADApplicationIdentifier to your app's Info.plist, plus the SKAdNetworkItems array for attribution.

<key>GADApplicationIdentifier</key>
<!-- Sample AdMob app ID: ca-app-pub-3940256099942544~1458002511 -->
<string>YOUR_ADMOB_APP_ID</string>
<key>SKAdNetworkItems</key>
<array>
  <dict>
    <key>SKAdNetworkIdentifier</key>
    <string>cstr6suwn9.skadnetwork</string>
  </dict>
  <!-- Include the full SKAdNetworkItems list (Google + third-party buyer IDs) -->
</array>

Replace YOUR_ADMOB_APP_ID with your AdMob app ID from the AdMob web interface.

Include the complete SKAdNetworkItems list as published by Google — keep this snippet as your single source of truth so it never drifts between pages.

Configure AppLovin

Performed by: Ad ops

Create the custom network: MAX → Mediation → Manage → Networks → Add a Custom Network → Network type SDK →

Custom Network : TapMind Market Place
Android Class  : com.tapmind.tech.TapMindMediationAdapterApplovin
iOS Class      : TapMindMediationAdapterApplovin

Add the yield partner: MAX → Mediation → Manage → Ad Units → select your ad unit → enable TapMind → enter:

App ID             : leave blank (optional)
Placement ID       : provided by your account manager
eCPM               : provided by your account manager
Custom Parameters  : "placementName": "provided by your account manager"

Warning: placementName must match exactly — case-sensitive, no leading/trailing spaces. A mismatch fails silently (no error, no fill).

Verify integration

Performed by: Developer

After install and dashboard configuration:

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.
Request an ad through your mediation SDK as you normally would.
Confirm a TapMind ad fills. Check logs for the tag TapMindAdapter.
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.

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 exactly; confirm ProGuard keep-rules ship
No fill at all	`placementName` mismatch (case/space) or wrong eCPM position	Re-check `placementName` exactly; 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
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.
