[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.
