Hi,

Thank you for sending your stack trace. It looks like you are using a custom player, MBPlayerDemo. I just have a couple of questions to clarify the issue that you are experiencing:

Would you be able to provide additional steps necessary in order for us to try to reproduce this issue?
If you can provide some code snippets and details of your implementation that may be helpful as well.
Also, have you experienced this issue with our sample examples?

Thanks,

Tyler Sidell

Hi Tyler,

I just tried out the sample examples->Swift->Basic Example and am seeing the same issue( Xcode Version 7.2, ios 9.2)

Please, let me know of there is any more info that I can provide.

Thanks

Hi Somya,

Can you please send us the answers to the questions proposed:

Would you be able to provide additional steps necessary in order for us to try to reproduce this issue?
If you can provide some code snippets and details of your implementation that may be helpful as well.

Does this prevent ad playback or crash your app?

If you can send us reproducible steps along with sample code snippets, that would be helpful to troubleshoot if there is a crash.

Thanks,

Hi Tyler,

I've posted my version of the sample here here. I didn't really change anything other than add a static reference to the Ads Framework as I'm also experiencing the same issue as this with the pods: https://groups.google.com/forum/#!topic/ima-sdk/2zDvx_KYHdo

Also, yes this is crashing the sample app. Look forward to your feedback.

Thanks

Hi Somya,

Did you intend to include an attachment to your sample? That did not seem to be attached.

Hi Somya,

Thank you for sending over your Github project. I also was able to see the error messages that you received, "Include of non-modular header inside framework module 'GoogleInteractiveMediaAds". Have you tried following the instructions outlined in this thread? This could also be related to an issue with XCode 7.1+. Have you tried adding the headers manually instead of using Cocoapods? Another suggestion would be to go to Build Settings -> Allow Non-Module includes in Framework Modules is set to 'Yes', clean project, then build.

Also, after I fixed the headers on the example I was not able to reproduce the crash that you are describing. Can you provide step-by-step analysis so that we can try to capture the behavior on our end? In addition, feel free to send over stack traces if you have them.

Thanks,

I'm getting the same issue. It doesn't look like a header issue because the project is compiling just fine. When it runs, though, I get the same crash:

Hi Scott,

Thank you for reporting this crash. May I suggest adding the library manually to see if you are having the same issues? There is a bug open with Cocoapods about this issue. In the meantime, I'll speak to the rest of our team to see if there is anything that can be done on our end.

Cheers,

The linker flag fixed things for me.

Hi,

I was able to solve the crash issue after setting the linker flag to "-all_load".

But when I added the "GoogleMobileAds.framework", app won't compile due "-all_load" linker flag.

Can I add Admob and IMA in my project? Or any solution to solve the compilation issue?

Hi Girish,

I believe the issue that you are facing is due to duplicate symbols being used by both the IMA and Mobile Ads SDK. Here is how I would suggest you to setup your project to include both the SDK's - 
First download the sample project for IMA. For this example, download the Basic Example for SWIFT. Next update the pod file to only include this - pod 'GoogleAds-IMA-iOS-SDK-For-AdMob' . Basically this pod would include both the IMA and AdMob SDK and would fix your duplicate symbols issue.
Next, the IDE would still likely throw the 'non-modular' error. The simplest way to fix this without changing the Linker Flags would be to open in Xcode -> Pods -> Pods -> GoogleAds-IMA-iOS-SDK-For-AdMob -> Frameworks -> GoogleInteractiveMediaAds.framework -> Headers -> GoogleInteractiveMediaAds.h and change it to the following -
#import "IMAAVPlayerContentPlayhead.h" 
#import "IMAAVPlayerVideoDisplay.h" 
#import "IMAAd.h" 
#import "IMAAdDisplayContainer.h"
#import "IMAAdError.h" 
#import "IMAAdEvent.h" 
#import "IMAAdPlaybackInfo.h" 
#import "IMAAdPodInfo.h" 
#import "IMAAdsLoader.h" 
#import "IMAAdsManager.h" 
#import "IMAAdsRenderingSettings.h" 
#import "IMAAdsRequest.h" 
#import "IMACompanionAdSlot.h" 
#import "IMAContentPlayhead.h" 
#import "IMAPictureInPictureProxy.h" 
#import "IMASettings.h" 
#import "IMAStreamManager.h" 
#import "IMAStreamRequest.h" 
#import "IMAUiElements.h" 
#import "IMAVideoDisplay.h"
Basically we are trying to directly import the header file here in the IMA SDK. That's it.
I have also attached a sample project that includes both the SDK's.
