Hi,
Want to know why in CarLauncherViewModel.java, the background is set to red

@Override
public void onTaskVanished(@NonNull ActivityManager.RunningTaskInfo taskInfo) {
if (DEBUG) {
Log.d(TAG, "MapsTaskView: onTaskVanished: taskId=" + taskInfo.taskId);
}
if (!sAutoRestartOnCrash) {
// RemoteCarTaskView color is set to red to indicate
// that nothing is wrong with the task view but maps
// in the task view has crashed. More details in
//

b/247156851

.
mRemoteCarTaskView.setBackgroundColor(Color.RED);
}
}

Janet, are you able to route this to a good PoC?

Hi Cal, is this something you can help with? I see in b/336337049, the issue may have been addressed though perhaps on a different branch? Thanks!

The reason to do this is because there are times when an app (which is an embedded task) has crashed but not the task view in which the app is embedded. So this serves as a good indicator whether it is a task view bug or an app bug.

There was a fix internally which was stopping the app from getting killed. Can you share some more details about when you are seeing this, branch and also attach a bugreport and winscope please? With that, we will be able to provide more context.

The red screen is shown every time when come back to homescreen from app list, on android 15 glodroid release. Due to company confidentiality policies, I am unable to provide the logs.

Is it possible to check a few things then:

Do you see some log like this I wm_finish_activity: .... recent-task-trimmed]?
Once the red screen is there and if you press home button again, is the red screen gone?
Are shell transitions enabled?

The snippet from #comment1 just sets the color to red. If the color is not red, a black screen would be there but the underlying problem would still exist with the app.

1. no
2. red screen only shows for a very short time, less than 1s
3. yes
