Missed this in my last patch, apparently getInputMethodManager can be called in a runnable as well.

Do you know which Runnable is calling getInputMethodManager() here? Can it handle a null return? Not all of GeckoInputConnection's calls to getInputMethodManager() handle null returns (which is appropriate for code paths that can only run when we have a View and Context).
Comment 3 Kartikaya Gupta ( 2012-07-26 10:53:19 PDT
In this case it's the runnable in notifyIMEChange, according to the stack trace. I looked through all of the calls to getInputMethodManager and all of the ones in runnables seem to handle null returns.
