Curiously, these hideSoftInputFromWindow() crashes are all Galaxy Tab users running Android 3.2 (Honeycomb). The NPE is [re]thrown by Parcel.readException(), which means the original NPE was thrown from InputMethodManagerService's hideSoftInput(). I wonder if there was a bug in Honeycomb's InputMethodManagerService that was fixed in ICS? Our client should not be able to trigger NPEs in the service!

Catch unexpected NullPointerException from InputMethodManagerService.

Comment on attachment 656966 [details] [diff] [review] catch-NPE.patch [Approval Request Comment] Bug caused by (feature/regressing bug #): N/A User impact if declined: Intermittent crashes for some Honeycomb tablet users. I suspect this is a bug in Honeycomb that was fixed in ICS+. Testing completed (on m-c, etc.): Tested locally, BUT this is an intermittent bug I have not repro'd myself. Risk to taking this patch (and alternatives if risky): Low risk. The code change simply catches a NullPointerException from Google code instead of crashing. String or UUID changes made by this patch: N/A

Comment on attachment 656966 [details] [diff] [review] catch-NPE.patch mobile-only, low risk, still early in beta - we can take this to branches.

This is still crashing at about the same rate as mentioned in comment 0.

Let's open a new bug for this. The patch was landed and pushed all the way to beta.
