EditText weird crash on LG Optimus w/Swype (works on emulator and Droids)

问题

I have an app which works in the emulator and on Droid phones. While testing on an LG Optimus (which BTW has Swype installed) it crashes with the following stack trace (NOTE: it is in the constructor of EditText).

What is weird is that supposed offending line in TextView (981) is the method signature for getDefualtView() and there are no references to GestureDetector in EditText or TextView in 2.2 source code.

I'm presuming (or hazarding a guess that it is most likely due to Swype) and am not sure of:

if it is swype, then how do i write my code so that it is swype friendly?
if it is not swype, then what could it be? Whats baffling is that it is in the constructor using default styles, and null for attributes.

any help is appreciated.

Kindest regards, S-

回答1:

I looked into sources and it seems that invoking Looper.prepare() in the UI thread will fix this exeption. But it's very strange. Are you using multiple threads?
