Hello,
This is baffling me. It must be something that I am doing wrong
fundamentally, but for the life of me I can't see it
Can a good soul help me please?
I am (supposedly) catching NullPointerException and returning 0 if
that happens. But occasionally I get
NullPointerException failure anyway.
Is catching it this way no enough to prevent this failure?
Thanks for your help.
private char getCharBehindCursor (int offset){ // get a single char
behind cursor + offsett
CharSequence cSeq;
InputConnection inputConnection = getCurrentInputConnection();
unicode
if (inputConnection != null){
try {
cSeq = inputConnection.getTextBeforeCursor (offset +
1, 0);
} catch (NullPointerException npe) {
/* failure*/
return (char)0;
}
if (cSeq.length() == offset+1){ // if we got
enough
characters
return cSeq.charAt(0); // we always
want the first one in the
returned string
}
}
return (char)0;
}
