Your catching a NullPointerException in your
inputConnection.getTextBeforeCursor call is unnecessary. You are already
checking to see if inputConnection is null. It From the documentation of
InputConnection, and I quote
This method may fail either if the input connection has become invalid (such
as its process crashing) or the client is taking too long to respond with
the text (it is given a couple seconds to return). In either case, a null is
returned.
end quote. So I would guess your NullPointerException is possibly in the
fact that the cSeq is null and you are calling the method length() on a
possibly null object.
In the future you will be better off reading and sending logcat output which
would probably have told you the line no where the Exception was thrown and
hence made it simpler...
