[IMA-SDK Android] An error occurs when trying to open the ad link in a custom tab

[pineapplevine1]

Hi IMA Team

We are developing a library that customizes Media3 and wraps the IMA SDK APIs, so that the app invokes the IMA SDK APIs through the library’s API.
Currently, with that implementation, when we call setEnableCustomTabs(true)—an IMA SDK API—and try to open an ad’s landing page in a custom tab, we encounter an Intent-related error.

> android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?

If you have any ideas about the cause of this issue or possible workarounds, please let us know.

Best Regards.

Hi,

Thank you for reaching out to the IMA SDK Support team.

The behavior you are experiencing when starting an Activity from a non-Activity context such as a Fragment is expected, as outlined in the documentation. You can try adding Intent.FLAG_ACTIVITY_NEW_TASK to your startActivity() call to see if that resolves the issue.Additionally, if you're using an older version of the SDK, we recommend updating to the latest version.

If the problem persists, please share the following details so we can investigate further.

• Sample project reproducing the issue
• Steps to replicate the issue
• Affected device information

Hi IMA Team

The startActivity() mentioned in the error message is not being called by our app or by our library that customizes Media3. We believe it is triggered by an Intent sent by the IMA SDK when the “Learn more” in the ad is tapped to open the link. Therefore, if FLAG_ACTIVITY_NEW_TASK is to be added, it would need to be handled within the IMA SDK’s processing.

Best Regards.

Hi,

Kindly apologies for the delay.

I have reviewed the provided sample project and was able to reproduce the crash. The crash occurs because setEnableCustomTabs(true) is being called inside the setupAdsRendering method. This call should be made within the onAdsManagerLoaded method, and the adsRenderingSettings object should be defined as a global variable.

I hope this helps! Let me know if you have any other questions.

Thanks,

Hi IMA Team

Based on your feedback, I have edited the sample project that I provided previously.
I changed the timing of the setEnableCustomTabs(true) call to onAdsManagerLoaded, and modified adsRenderingSettings to be a global variable. I tested the changes, but the situation has not improved.
Has the issue been resolved on your side?
I would like to confirm whether there is any discrepancy in our understanding of the modification method.

Best Regards.

Hi,

Thanks for getting back to us.

We have identified a change needed in the AdTagLoader class within the lib-exoplayer-ima module to address the crash issue. Currently, the line adsRenderingSettings.setEnableCustomTabs(true) is placed inside the setupAdsRendering() method (around line 627). This line should be removed from this method. Instead, set the setEnableCustomTabs(true) property inside the onAdsManagerLoaded() method (around line 1418) of the same class, as shown below:

AdsRenderingSettings adsRenderingSettings = imaFactory.createAdsRenderingSettings();
adsRenderingSettings.setEnableCustomTabs(true);

After applying the above changes, I tested the implementation and the crash no longer occurs. Please try these modifications on your end as well, and if the issue still persists, kindly share an updated sample project for further analysis.

Hi IMA Team

I have applied the changes you suggested and performed a functionality check.
It no longer crashes, but the configuration for setEnableCustomTabs(true) is not taking effect, and when tapping “Learn more,” the link opens in a web browser.
The expected behavior when setEnableCustomTabs(true) is set is that the link should open in the app's custom tab instead of in the web browser.

Best Regards.
