Hello,
I am trying to understand why the Toast behavior is longer, when I
dispatch key events such as "home", "menu", and "search", compare to
when I dispatch key event "back".
The way I invoke Toast is:
- intercept back, home, menu, and search key events in dispatchKey()
- instead of doing normal business, I throw a broadcast intent when
key action is UP:
(I tried both function below yields the same finding) :
mContext.getApplicationContext().sendBroadcast(broadcastIntent);
or
mContext.sendBroadcast(broadcastIntent);
- my test apk listen to the broadcast intent and do a with
Toast.LENGTH_SHORT
Compare the log, paste below, for "back" and "home" key, it appears
there is extra "add window" operation when home key is pressed but not
"back" key.
Is there some flag that I should be setting it to by pass this "add
window" operation?
Any insight is helpful.
Thanks,
Alvin
