We're seeing a similar error in our code. Appears to be a combination of AGP 8.6.0 and Kotlin 2 needed to hit it.

private fun Intent.stripUnwantedFlags() {
    // Explicitly remove the new task and clear task flags (Our browser activity is a single
    // task activity and we never want to start a second task here).
    flags = flags and Intent.FLAG_ACTIVITY_NEW_TASK.inv()
    flags = flags and Intent.FLAG_ACTIVITY_CLEAR_TASK.inv()

    // IntentReceiverActivity is started with the "excludeFromRecents" flag (set in manifest). We
    // do not want to propagate this flag from the intent receiver activity to the browser.
    flags = flags and Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS.inv()
}

All 3 lines then hit:

Must be one or more of: Intent.FLAG_GRANT_READ_URI_PERMISSION, Intent.FLAG_GRANT_WRITE_URI_PERMISSION, Intent.FLAG_FROM_BACKGROUND, Intent.FLAG_DEBUG_LOG_RESOLUTION, Intent.FLAG_EXCLUDE_STOPPED_PACKAGES, Intent.FLAG_INCLUDE_STOPPED_PACKAGES, Intent.FLAG_GRANT_PERSISTABLE_URI_PERMISSION, Intent.FLAG_GRANT_PREFIX_URI_PERMISSION, Intent.FLAG_ACTIVITY_MATCH_EXTERNAL, Intent.FLAG_ACTIVITY_NO_HISTORY, Intent.FLAG_ACTIVITY_SINGLE_TOP, Intent.FLAG_ACTIVITY_NEW_TASK, Intent.FLAG_ACTIVITY_MULTIPLE_TASK, Intent.FLAG_ACTIVITY_CLEAR_TOP, Intent.FLAG_ACTIVITY_FORWARD_RESULT, Intent.FLAG_ACTIVITY_PREVIOUS_IS_TOP, Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS, Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT, Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED, Intent.FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY, Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET, Intent.FLAG_ACTIVITY_NEW_DOCUMENT, Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET, Intent.FLAG_ACTIVITY_NO_USER_ACTION, Intent.FLAG_ACTIVITY_REORDER_TO_FRONT, Intent.FLAG_ACTIVITY_NO_ANIMATION, Intent.FLAG_ACTIVITY_CLEAR_TASK, Intent.FLAG_ACTIVITY_TASK_ON_HOME, Intent.FLAG_ACTIVITY_RETAIN_IN_RECENTS, Intent.FLAG_ACTIVITY_LAUNCH_ADJACENT, Intent.FLAG_ACTIVITY_REQUIRE_NON_BROWSER, Intent.FLAG_ACTIVITY_REQUIRE_DEFAULT, Intent.FLAG_RECEIVER_REGISTERED_ONLY, Intent.FLAG_RECEIVER_REPLACE_PENDING, Intent.FLAG_RECEIVER_FOREGROUND, Intent.FLAG_RECEIVER_NO_ABORT, Intent.FLAG_RECEIVER_VISIBLE_TO_INSTANT_APPS

The initial report (comment#1) seems like a dup of b/352609562 (internal link), and fixed at https://cs.android.com/android-studio/platform/tools/base/+/f88d11033727f891bcc2a7a1cbbeb109c7d5dd0f I believe it's available in AGP 8.7.0-alpha02+

However, comment#2 indicates that there are more kinds of conversions we may miss... Let me double-check that.

Thanks for fixing! What release should we be able to verify the fix in? And is there any chance of a backport for 8.6.1?

The caveat is that the fix for comment#1 is in 8.7.0-alpha02 and the fix for comment#2 will be in 8.8.0-alpha02. I'm asking internally how we can handle this case.

the fix for comment#2 will be in 8.8.0-alpha02

It is cherry-picked to 8.7

the fix for comment#1 is in 8.7.0-alpha02

This one and the above one are cherry-picked to 8.6.1

Thanks for the update!

Thank you for your patience while our engineering team worked to resolve this issue. A fix for this issue is now available in:

• Android Studio Ladybug Feature Drop | 2024.2.2 Canary 2
• Android Gradle Plugin 8.8.0-alpha02

We encourage you to try the latest update.

If you notice further issues or have questions, please file a new bug report.

Thank you for taking the time to submit feedback — we really appreciate it!

The fixes for this issue are now also available in:

• Android Studio Ladybug | 2024.2.1 RC 1
• Android Gradle Plugin 8.7.0-rc01

We encourage you to try the latest update.

If you notice further issues or have questions, please file a new bug report.

Comment #25, note that the team member who works on this is OOO for a few days and may not respond for a little while. According to the comments above, yes, AGP 3.6.3 should include the fix.

Do you have repro steps? Just to help ensure that this is, in fact, the same issue reported here? There might be multiple paths to produce the same error, etc. etc. If you're certain it's the same issue as here, then repro steps will help us determine if we should reopen this. Otherwise, it might be best to file a new bug since this one seems to have quite a bit of history on it.

Meanwhile, there are 20 +1's on this bug. Can anyone else who was experiencing this report that it was actually fixed for them starting in 3.6.0?

Thanks! David

Hey David,

I think this may have regressed. I created a fork of the original sample project with AGP 4.1.2.

https://github.com/saadfarooq/Robolectric-Databinding-Lib

The Robolectric test fails with the same error. If kotlin-kapt plugin is removed, the test passes. But then the buildFeatures databinding config says If you plan to use data binding in a Kotlin project, you should apply the kotlin-kapt plugin.

So possibly something to do with kapt?

Ooof :) Hung, are you swamped? Would you be able to take a look?

Comment #27, in the meanwhile, it may be worth trying things out with a more recent version of AGP (e.g. using beta or canary) to see if this remains broken after 4.1.2, or if this was a temporary regression.

Hung: I meant to say, I reopned this bug, but if it ends up being a different cause, or just because this bug already has so much history, feel free to reclose it and create a new one.

I tried 4.2.0-beta05 and 7.0.0-alpha8 in Arctic Fox Canary 08 and the behavior is the same. Remove kapt, test passes. Added it back, get the NoClassDefFound error.

Thank you for the sample project! This issue was mentioned earlier at comment #20, 21, 23.

This is caused by https://youtrack.jetbrains.com/issue/KT-27404, originally reported at Issue 117145132.

Basically, when using kapt, users will need to add:

• kaptTest some-random-dependency for kapt to run annotation processing on unit test source code, which in this case will include the missing data binding classes.
• kaptAndroidTest some-random-dependency for kapt to run annotation processing on androidTest source code.

Please follow the Kapt bug above for progress on this issue.

@David: I'm closing this issue as this should ideally be fixed by the Kotlin Gradle plugin.
