Hi Chelamcherla,

   This chrome issues has been seen intermittently in all the Android GMS version we tested from M, N and O. In this particular case Chrome was likely running in the background, since the test case when failure occurred was 'Send an email with no attachment using WLAN'. Device was in the email app composing and sending email with no attachment.

Please let Me know if you need more info on the same.

Thank you for providing more feedback. Adding the requester to the cc list.

Revert ASAP.

For Device 4 the logcat shows these (note the "bg anr" for chrome) but I'm not sure why:

The following is not the root-cause of ANR. ANR happened before that warning got logged.

10-06 11:14:13.920 W/PackageManager( 1312): Caller hasn't been triaged for missing apps;

As you can see from the below log snippet, there is a time-out on executing CustomTabsConnectionService.

0-06 11:14:13.609 W/ActivityManager( 1312): Timeout executing service: ServiceRecord{34464f1 u0 com.android.chrome/org.chromium.chrome.browser.customtabs.CustomTabsConnectionService}

Please check on why this time-out happened.

Hi,

Thanks for the report, and sorry for the long delay to get a reply.

From the logs, I doubt the actual issue is linked to Chrome. The log line you're referring to above happens when a service fails to start, which AFAICT from a cursory look at AOSP source code means that it failed to reach the Java entry point in the Service class.

If that's the case, then it's likely that something is blocking it in the framework. In this instance, there is a lot of exceptions on device 5. It's possible that it held a lock in PackageManager the prevented the device from starting.

Is this a device with significant Android framework changes?

Hi, I already checked the ANR logs. There no locks or deadlocks holding our chrome process.
And there is no much changes in framework as well.
Revert to me if you need more info on the same.
Thanks for your reply

This issue got reproduced again.

SERVICE TIME-OUT
10-17 18:39:48.028 W/ActivityManager( 1324): Timeout executing service: ServiceRecord{da9901a u0 com.android.chrome/org.chromium.chrome.browser.customtabs.CustomTabsConnectionService}

ANR
10-17 18:39:48.300 E/ActivityManager( 1324): ANR in com.android.chrome
10-17 18:39:48.300 E/ActivityManager( 1324): PID: 18684

Please check why CustomTabsConnectionService is getting called again and again while composing an email on GMail app.

Thanks for your time.
