This guide shows you how to use Google Mobile Ads Flutter Plugin to load and display ads from Mintegral using [mediation](https://developers.google.com/admob/flutter/mediation.md.txt), covering both waterfall and bidding integrations. It covers how to add Mintegral to an ad unit's mediation configuration, and how to integrate the Mintegral SDK and adapter into a Flutter app. ## Supported integrations and ad formats The AdMob mediation adapter for Mintegral has the following capabilities: | Integration || |---|---| | Bidding | Yes | | Waterfall | Yes | | App Open | Yes | | Banner | Yes | | Interstitial | Yes | | Rewarded | Yes | | Rewarded Interstitial | | | Native | Yes | ## Prerequisites Before you continue, verify the following: - Latest Google Mobile Ads Flutter Plugin version. - Flutter framework version 3.7.0 or later. - To deploy on Android - Android API level 24 or later. - To deploy on iOS - iOS deployment target of 13.0 or later. - A working Flutter project configured with the Google Mobile Ads Flutter Plugin. See [Set up Google Mobile Ads Flutter Plugin](https://developers.google.com/admob/flutter/quick-start.md.txt) for details. - [Set up AdMob Mediation](https://developers.google.com/admob/flutter/mediation.md.txt). ## Step 1: Set up configurations in Mintegral UI - [Sign up](https://dev.mintegral.com/user/signup) or [Log in](https://dev.mintegral.com/user/login) to your Mintegral account. ### Locate the App Key - Navigate to the **APP Setting** tab and take note of the **APP Key**. -  ### Add a new application - From the **APP Setting** tab, click the **Add APP** button. -  - Select the **Platform** and fill out the rest of the form. Then, click **Save**. ### Android  ### iOS  - Take note of your application's **APP ID**. ### Android  ### iOS  ### Create an ad placement - Once your application has been created, navigate to the **Placements \& Units** tab and click on the **Add Placement** button as shown below to create your ad placement. ### Android  ### iOS  - Enter a **Placement Name** and **AD Format**. > [!IMPORTANT] > **Important:** For native ad format, select **Native (Custom Rendering)** as the **AD Format**. ### Bidding Select **Header Bidding** as the **Bidding Type** . Fill out the rest of the form and click **Save**.  ### Waterfall Select **Waterfall** as the **Bidding Type** . Fill out the rest of the form and click **Save**.  - Once your ad placement is created, take note of the **Placement ID**. ### Android  ### iOS  - Click the **1 AD Units** drop down and take note of the **AD Unit ID**. ### Android  ### iOS  ### Locate your Mintegral Reporting API Key ### Bidding This step isn't required for bidding integrations. ### Waterfall You will need your Mintegral Reporting API Key for setting up your AdMob ad unit ID. Navigate to **Account** \> **API Tools** . Take note of your **Skey** and **Secret**.  ### Update your app-ads.txt - [Authorized Sellers for Apps app-ads.txt](https://iabtechlab.com/wp-content/uploads/2019/03/app-ads.txt-v1.0-final-.pdf) is an IAB Tech Lab initiative that helps ensure your app ad inventory is only sold through channels you've identified as authorized. To prevent a significant loss in ad revenue, you'll need to implement an `app-ads.txt` file. If you haven't done so already, [set up an app-ads.txt file for your app](https://support.google.com/admob/answer/9363762). - To implement `app-ads.txt` for Mintegral, see [How app-Ads.txt Can Help Fight Ad Fraud](https://www.mintegral.com/en/blog/how-app-ads-txt-can-help-fight-ad-fraud). ## Step 2: Set up Mintegral demand in AdMob UI ### Configure mediation settings for your ad unit ### Android For instructions, see step 2 in the guide for [Android](https://developers.google.com/admob/android/mediation/mintegral.md.txt#step-2). ### iOS For instructions, see step 2 in the guide for [iOS](https://developers.google.com/admob/ios/mediation/mintegral.md.txt#step-2). ### Add Mobvista/Mintegral to GDPR and US state regulations ad partners list > [!IMPORTANT] > **Important:** Verify that you have **Account Management** permission to complete the configuration for EU Consent and GDPR, US State regulations, and User Messaging Platform. See [Manage user access to your > account](https://support.google.com/admob/answer/2784628) for details. - Follow the steps in [European regulations settings](https://support.google.com/admob/answer/10113004#adding_ad_partners_to_published_gdpr_messages) and [US state regulations settings](https://support.google.com/admob/answer/14125907) to add **Mobvista/Mintegral** to the European and US state regulations ad partners list in the AdMob UI. ## Step 3: Import the Mintegral SDK and adapter > [!NOTE] > **Note:** Failure to integrate the compatible Mintegral and Google Mobile Ads Flutter Plugin versions might lead to build issues. ### Integration through pub.dev - (Android only) Add the following repositories to the `build.gradle` file inside your project's `android` directory: ```groovy repositories { google() mavenCentral() maven { url = uri("https://dl-maven-android.mintegral.com/repository/mbridge_android_sdk_oversea") } } ``` - Add the following dependency with the latest versions of the Mintegral SDK and adapter in your package's `pubspec.yaml` file: ```yaml dependencies: gma_mediation_mintegral: ^2.1.5 ``` ### Manual Integration - Download the latest version of Google Mobile Ads mediation plugin for [Mintegral](https://pub.dev/packages/gma_mediation_mintegral/versions), extract the downloaded file, and add the extracted plugin folder (and its contents) to your Flutter project. Then, reference the plugin in your `pubspec.yaml` file by adding the following dependency: ```yaml dependencies: gma_mediation_mintegral: path: path/to/local/package ``` ## Step 4: Implement privacy settings on Mintegral SDK ### EU consent and GDPR - To [comply with the Google EU User Consent Policy](https://www.google.com/about/company/consentstaging.html), you must make certain disclosures to your users in the European Economic Area (EEA), the UK, and Switzerland, and obtain their consent for the use of cookies or other local storage where legally required, and for the collection, sharing, and use of personal data for ads personalization. This policy reflects the requirements of the EU ePrivacy Directive and the General Data Protection Regulation (GDPR). You are responsible for verifying that consent is propagated to each ad source in your mediation chain. - Mintegral Flutter adapter version 2.1.1 and later supports passing GDPR consent signals from consent management platforms that integrate with IAB's Transparency and Consent Framework (TCF) to Mintegral SDK. For more information, see Mintegral's [Android](https://dev.mintegral.com/doc/index.html?file=sdk-m_sdk-android&lang=en#sdkprivacycompliancestatement) and [iOS](https://dev.mintegral.com/doc/index.html?file=sdk-m_sdk-ios&lang=en#sdkprivacycompliancestatement) SDK Privacy Compliance Statement documentation. ## Step 5: Add required code ### Android No additional code is required for Mintegral integration. ### iOS ### SKAdNetwork integration Follow [Mintegral's documentation](https://dev.mintegral.com/doc/index.html?file=sdk-m_sdk-ios&lang=en) to add the SKAdNetwork identifiers to your project's `Info.plist` file. ## Step 6: Test your implementation ### Enable test ads - Make sure you [register your test device](https://developers.google.com/admob/flutter/test-ads.md.txt#enable_test_devices) for AdMob. - To get Mintegral test ads for banners, interstitials, rewarded and native ad formats, Mintegral recommends using the App Keys, App IDs, Placement IDs and Ad Unit IDs provided in the [Mintegral Test ID page](https://dev.mintegral.com/doc/index.html?file=sdk-m_sdk-ios&lang=en#testid). > [!IMPORTANT] > **Important:** Disable test mode for AdMob and Mintegral before releasing your app. ### Verify test ads - To verify that you are receiving test ads from Mintegral, enable [single ad source testing](https://developers.google.com/admob/flutter/ad-inspector.md.txt#single_ad_source_testing) in ad inspector using the **Mintegral (Bidding) and Mintegral (Waterfall)** ad source(s). ## Error codes - If the adapter fails to receive an ad from Mintegral, you can check the underlying error from the ad response using [`ResponseInfo`](https://developers.google.com/admob/flutter/response-info.md.txt) under the following classes: ### Android ```java com.mbridge.msdk com.google.ads.mediation.mintegral.MintegralMediationAdapter ``` ### iOS ```objective-c GADMediationAdapterMintegral ``` - Here are the codes and accompanying messages thrown by the Mintegral adapter when an ad fails to load: ### Android | Error code | Domain | Reason | |---|---|---| | 100 | com.mbridge.msdk | The Mintegral SDK returned a failure callback. | | 101 | com.google.ads.mediation.mintegral | Invalid server parameters (e.g. Missing app ID or placement ID). | | 102 | com.google.ads.mediation.mintegral | The requested ad size does not match a Mintegral supported banner size. | | 103 | com.google.ads.mediation.mintegral | Missing or invalid bid response. | | 104 | com.google.ads.mediation.mintegral | Mintegral SDK returned a no fill error. | | 105 | com.mbridge.msdk | Mintegral SDK failed to initialize. | | 106 | com.google.ads.mediation.mintegral | An ad for the Mintegral slot is already loaded and is yet to be shown. | ### iOS | Error code | Domain | Reason | |---|---|---| | 101 | com.google.mediation.mintegral | Invalid server parameters (e.g. Missing app ID or placement ID). | | 102 | com.google.mediation.mintegral | Mintegral SDK returned a no fill error. | | 103 | com.google.mediation.mintegral | Mintegral SDK failed to show an ad. | | 104 | com.google.mediation.mintegral | The requested ad size does not match a Mintegral supported banner size. | ## Mintegral Flutter Mediation Adapter Changelog #### Version 2.1.6 (In progress) #### Version 2.1.5 -
