The CrystalExpress AdMob Custom Event allows AdMob publishers to add CrystalExpress as a Custom Ad Network within the AdMob platform.

CrystalExpress provides four ad formats for AdMob mediation. The relationship between AdMob ad unit and ad format in CrystalExpress is as following:

AdMob ad unit	AD format from CrystalExpress
Banner	Card AD
Rewarded Video	Rewarded Video AD
Interstitial	Splash AD
Native Advanced	Native AD (image only)

NOTICE: The aspect ratio for CrystalExpress ad is 16:9, 4:3 or 1:1.

Before adding CrystalExpress as Custom network, you have to integrate AdMob SDK by following the instructions on the AdMob website.

NECESSARY STEPS:

• Get CrystalExpress SDK and Crystal ID.

• Integrate the CrystalExpress SDK.

• Add CrystalExpress AdMob Custom Event into project.

• Configure AdMob to mediate CrystalExpress.

Get CrystalExpress SDK and Crystal ID

Please contact your Intowow account manager. We will provide the appropriate version of SDK and Crystal ID to fit your needs.

Integrate the CrystalExpress SDK.

Step 1

Unzip the SDK package, and you could find static library, header files, and sample app.

Step 2

Add ce-[premium|lite]-[global|cn]-[version].a to your project via Build Phases -> Link Binary With Libraries in the project setting of Xcode.

Step 3

Add header files to project.

Step 4

Make sure all of the following frameworks are added into Build Phases.

• Security.framework

• CFNetwork.framework

• MessageUI.framework

• MobileCoreServices.framework

• SystemConfiguration.framework

• AdSupport.framework

• libz.dylib

• libc++.dylib

• CoreTelephony.framework

• CoreMedia.framework

• libsqlite3.dylib

• AVFoundation.framework

• libicucore.dylib

Step 5

Add -ObjC flag in TARGETS -> Build Settings -> Linking -> Other Linker Flags.

Step 6

Copy CrystalExpress.plist to your project and set the Crystal_Id value to Crystal ID you received from Intowow account manager.

Step 7

Import I2WAPI.h in AppDelegate.m. Initialize SDK in application:didFinishLaunchingWithOptions: of AppDelegate.m:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // init SDK
    [I2WAPI initWithVerboseLog:NO isTestMode:NO];
    return YES;
}

• Enable/disable debugging message from SDK with initWithVerboseLog:(BOOL).

• Set SDK to test mode by isTestMode:(BOOL) for development.

Step 8

iOS 9 and later versions block http connection by default. Since most of the redirect links of ads use HTTP protocol, we have to modify Info.plist in your project to allow HTTP connections.

<key>NSAppTransportSecurity</key>
<dict>
     <key>NSAllowsArbitraryLoads</key>
     <true/>
</dict>

Add CrystalExpress AdMob Custom Event into project

Step 1

Contact Intowow account manager for CrystalExpress AdMob Custom Event and sample code.

Step 2

Unzip ce-[premium|lite]-global-custom-event-SDKversion.zip, and add files under AdMobDemo/CrystalExpress_Google_CustomEvent/ to your project according to following different propose.

• For Banner:

  Banner/CECustomEventCard.h

  Banner/CECustomEventCard.m

  Common/UIView+CELayoutAdditions.h

  Common/UIView+CELayoutAdditions.m

• For Native Advanced: (For now, we only support native image ad)

  NativeAdvanced/CECustomEventNativeAdvanced.h

  NativeAdvanced/CECustomEventNativeAdvanced.m

  NativeAdvanced/CEMediatedNativeAppInstallAd.h

  NativeAdvanced/CEMediatedNativeAppInstallAd.m

• For Rewarded Video:

  RewardedVideo/CEMediationAdapterRewardedVideo.h RewardedVideo/CEMediationAdapterRewardedVideo.m

• For Interstitial: Interstitial/CECustomEventInterstitial.h Interstitial/CECustomEventInterstitial.m

For further integration issues, please check the sample code within download folder.

The Layout of CrystalExpress AD

In AdMob Custom Event, our SDK will keep the aspect ratio of creatives and try to fit the ad view that you bind to AdMob.

If the aspect ratio for the ad view to be bound and the creative are inconsistent, the return ad will be filled with black background to match the aspect ratio.
