Requirements

• Android API level 16 or higher

• Latest Google Mobile Ads SDK

Step 1: Set up InMobi

Sign up or log in to your InMobi account.

Add an app

Click the Add an App button to add your app to InMobi.

Enter your app's URL and click the Look Up button. Otherwise click Have an app that isn't yet published?

Enter the name of your app and choose Android as the Platform. Select whether or not your app is COPPA compliant and click Add App when done.

Placements

InMobi requires you to create a placement before you finish adding your app.

Note: To add a placement to an existing app, open your app details page by clicking on your app's name in the InMobi dashboard and navigate to the Placements tab located in the left navigation bar. Then click the Add Placement button.

Banner

Select BANNER as the type and enter a Placement Name. Click the Create Placement button when done.

Once the placement is created, its details are shown. Take note of the Placement ID, which will be used for setting up your Ad Manager ad unit.

Interstitial

Select INTERSTITIAL as the type and enter a Placement Name for your placement. Click the Create Placement button when done.

Once the placement is created, the placement details are are shown. Take note of the Placement ID, which will be used for setting up your Ad Manager ad unit.

Rewarded Video

Select REWARDED VIDEO as the type and enter a Placement Name for your placement. Click the Create Placement button when done.

Once the placement is created, its details are are shown. Take note of the Placement ID, which will be used later to set up your Ad Manager ad unit. Enter values for Key and Value for the reward details.

Note: The reward value specified here is forwarded by the adapter unless reward values are overridden on the Ad Manager UI.

Native

Select NATIVE CONTENT as the type and enter a Placement Name for your placement. Click the Create Placement button when done.

Once the placement is created, its details are are shown. Take note of the Placement ID, which will be used later to set up your Ad Manager ad unit. Select either PREROLL, STREAM, or SPLASH as the Native Ad Layout style and click Customize.

The FEED Native Ad Layout does not contain some of the assets that are required by Google Mobile Ads SDK and the adapter would fail the ad request if one of the required assets is missing.

Note: The Native Ad Layout styles displayed here are just suggestions. You can still customize the layout of your native ad in code.

Select the desired size for Screenshots (main image), then click Save.

---

Account ID

Now that the placement has been created, click Proceed to Integration, then click Done.

Next, you will get your Account ID, which can be found by clicking on your email address (located in the top-right corner of your InMobi dashboard).

In addition to your Account ID and Placement ID you need a secret key provided by InMobi. Contact the InMobi support team to obtain your key.

Step 2: Configure mediation settings for your Ad Manager ad unit

Sign in to your Ad Manager account. Navigate to Delivery > Yield groups and click the New yield group button.

Enter a unique Name for your yield group, set the Status to Active, select your Ad Format, and set the Inventory type to Mobile App. Under the Targeting > Inventory section, select the Ad Unit ID to which you want to add mediation.

Next, click the Add yield partner button.

If you already have a Yield partner for InMobi, you can simply select it. Otherwise, select Create a new yield partner.

Select InMobi as the Ad network and enter a unique Name. Enable Mediation and turn on Automatic data collection, and enter the Secret Key obtained from InMobi support. Next, enter your Username and click Save when done.

Once the Yield partner is selected, choose Mobile SDK mediation as the Integration type, Android as the Platform, and Active as the Status. Enter the Account ID and the Placement ID obtained in the previous section and a Default CPM value.

Click Save at the bottom of the page when done.

Note: Automatic data collection takes a few days to gather data before it can accurately calculate a Dynamic CPM value for a mediation network. Once the eCPM can be calculated, it will be automatically updated on your behalf.

Using rewarded video ads

In the settings for your rewarded video ad unit, provide values for the reward amount and reward type. Then, to ensure you provide the same reward to the user no matter which ad network is served, check the Override reward settings from third-party ad networks when using mediation box.

If you don't apply this setting, the InMobi adapter passes back the reward specified in the InMobi dashboard when creating the placement.

Step 3: Import the InMobi SDK and adapter

Android Studio integration (recommended)

Add the following implementation dependencies with the latest version of the InMobi SDK and adapter in the app-level build.gradle file:

repositories {
    jcenter()
}

...
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'com.google.android.gms:play-services-ads:19.7.0'
    implementation 'com.google.ads.mediation:inmobi:9.1.6.0'
}
...

Migrate project to AndroidX

The InMobi SDK depends on Android support libraries but the latest Google Mobile Ads SDK uses Jetpack libraries.

To ensure the InMobi SDK and the Google Mobile Ads SDK are compatible, create a gradle.properties file in the top-level of your project, and add the following code:

android.useAndroidX=true
android.enableJetifier=true

This will rewrite the InMobi SDK binary to use use Jetpack libraries. See AndroidX migration guide for more information about these settings.

Manual integration

• Download the InMobi Android SDK and extract the InMobiSDK.aar file under the libs folder and add it to your project.

• Download the latest InMobi adapter .aar file from Bintray, and add it to your project.

• Download the latest version of Picasso Android library and add the picasso-version.jar file to your project.

Android RecyclerView library is part of the v7 Support Libraries and can be located under your Android SDK directory. Extract the android-support-v7-recyclerview.jar file from android-sdk-dir/extras/android/support/v7/recyclerview/libs/ and add it to your project.

Step 4: Additional code required

No additional code is required for InMobi integration.

Step 5: Test your implementation

To enable test ads for a placement, go to your app's details page by clicking on your app's name in the InMobi dashboard and navigate to the Placements tab located in the left navigation bar. Select the placement for which you want to enable test ads and click on the Diagnostics section to expand it.

You can choose either Global ON or Selective ON as the Test Mode. If you select Selective ON, you need to add a test device. Make sure that InMobi Test Ad is selected as the Test ad.

Optional steps

EU Consent and GDPR

Under the Google EU User Consent Policy, you must ensure that certain disclosures are given to, and consents obtained from, users in the European Economic Area (EEA) regarding the use of device identifiers and personal data. This policy reflects the requirements of the EU ePrivacy Directive and the General Data Protection Regulation (GDPR). When seeking consent, you must identify each ad network in your mediation chain that may collect, receive, or use personal data and provide information about each network's use. Google currently is unable to pass the user's consent choice to such networks automatically.

The section below shows you how to enable or disable personalized ads for InMobi.

In version 7.1.0.0, the InMobi adapter added the InMobiConsent class that allows you to pass consent information to InMobi. The following sample code calls updateGDPRConsent() on the InMobiConsent class. If you choose to call this method, it is recommended that you do so prior to requesting ads via the Google Mobile Ads SDK.

Note: Your app must reference both the InMobi adapter 7.1.0.0 or higher and the InMobi SDK 7.1.0 or higher to use the code below.

import com.inmobi.sdk.InMobiSdk;
import com.google.ads.mediation.inmobi.InMobiConsent;
// ...

JSONObject consentObject = new JSONObject();
try {
  consentObject.put(InMobiSdk.IM_GDPR_CONSENT_AVAILABLE, true);
  consentObject.put("gdpr", "1");
} catch (JSONException exception) {
  exception.printStackTrace();
}

InMobiConsent.updateGDPRConsent(consentObject);

See InMobi's GDPR implementation details for more information about the possible keys and values that InMobi accepts in this consent object.

Permissions

For optimal performance, InMobi recommends adding the following optional permissions to your app's AndroidManifest.xml file.

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

Network-specific parameters

The InMobi adapter supports additional request parameters that can be passed to the adapter as an Android Bundle. The adapter looks for the following keys in the bundle:

Request parameters and values
InMobiNetworkKeys.AGE_GROUP The user's age group.	InMobiNetworkValues.BELOW_18 InMobiNetworkValues.BETWEEN_18_AND_24 InMobiNetworkValues.BETWEEN_25_AND_29 InMobiNetworkValues.BETWEEN_30_AND_34 InMobiNetworkValues.BETWEEN_35_AND_44 InMobiNetworkValues.BETWEEN_45_AND_54 InMobiNetworkValues.BETWEEN_55_AND_65 InMobiNetworkValues.ABOVE_65
InMobiNetworkKeys.EDUCATION The user's education level.	InMobiNetworkValues.EDUCATION_HIGHSCHOOLORLESS InMobiNetworkValues.EDUCATION_COLLEGEORGRADUATE InMobiNetworkValues.EDUCATION_POSTGRADUATEORABOVE
InMobiNetworkKeys.AGE	String. The age of the user
InMobiNetworkKeys.POSTAL_CODE	String. The user's postal code (usually a five-digit number)
InMobiNetworkKeys.AREA_CODE	String. The user's area code (part of the telephone number)
InMobiNetworkKeys.LANGUAGE	String. The user's native language (if known).
InMobiNetworkKeys.CITY	String. The user's city
InMobiNetworkKeys.STATE	String. The user's state
InMobiNetworkKeys.COUNTRY	String. The user's country
InMobiNetworkKeys.LOGLEVEL Sets the Log level for InMobi SDK.	InMobiNetworkValues.LOGLEVEL_NONE InMobiNetworkValues.LOGLEVEL_DEBUG InMobiNetworkValues.LOGLEVEL_ERROR

Here's a code example of how to set these ad request parameters:

JAVA

Bundle extras = new Bundle();
extras.putString(InMobiNetworkKeys.AGE_GROUP, InMobiNetworkValues.BETWEEN_35_AND_54);
extras.putString(InMobiNetworkKeys.AREA_CODE, "12345");
...
PublisherAdRequest request = new PublisherAdRequest.Builder()
        .addNetworkExtrasBundle(InMobiAdapter.class, extras)
        .build();

KOTLIN

val extras = Bundle()
extras.putString(InMobiNetworkKeys.AGE_GROUP, InMobiNetworkValues.BETWEEN_35_AND_54)
extras.putString(InMobiNetworkKeys.AREA_CODE, "12345")
...
val request = PublisherAdRequest.Builder()
        .addNetworkExtrasBundle(InMobiAdapter.class, extras)
        .build()

Using native ads

Ad rendering

The InMobi adapter returns its native ads as UnifiedNativeAd objects. It populates the fields described in Custom native ad formats for a UnifiedNativeAd.

Field	Assets always included by InMobi adapter
Headline
Image
Body
App icon
Call to action
Star rating
Store
Price

Impression and click tracking

The Google Mobile Ads SDK uses the InMobi SDK's callbacks for impression and click tracking, so the reports on both dashboards should match up with few to no discrepancies.

Media views

InMobi does not provide an image asset for any native ads (video or static). For non-video ads, InMobi's SDK populates its media view with an image asset instead. To avoid potential null pointer errors, the InMobi adapter automatically creates a blank NativeAd.Image and includes it in the images asset array that's part of the ad object received by the app.

Publishers mediating to InMobi are encouraged to avoid using the image assets directly, and instead use MediaView in their UI. Ads loaded via the InMobi adapter will always provide a media view, which will automatically display video assets for ads that contain them and an image asset for ads that don't.

Error codes

If the adapter fails to receive an ad from InMobi, publishers can check the underlying error from the ad response using ResponseInfo.getAdapterResponse() under the following classes:

com.google.ads.mediation.inmobi.InMobiAdapter
com.google.ads.mediation.inmobi.InMobiMediationAdapter

Here are the codes and accompanying messages thrown by the InMobi adapter when an ad fails to load:

Error code	Reason
0-99	InMobi SDK Errors. See code for more details.
100	InMobi server parameters configured in the Ad Manager UI are missing/invalid.
101	Failed to initialize the InMobi SDK.
102	The requested ad size does not match an InMobi supported banner size.
103	Ad request is not a unified native ad request.
104	Attempted to request an InMobi ad without initializing the InMobi SDK. This should in theory never happen since the adapter initializes the InMobi SDK prior to requesting InMobi ads.
105	InMobi's ad is not yet ready to be shown.
106	InMobi failed to display an ad.
107	InMobi returned a native ad that is missing a required asset.
108	InMobi's native ad image assets contain a malformed URL.
109	The adapter failed to download InMobi's native ad image assets.
