your textwathcer changes text watching, causing call watcher, causing change text, ... , on until run out of stack space invoking methods.

one way fix set boolean flag true when you're running inside watcher , return if flag set kill recursion. in pseudocode:

boolean misinwatcher = false;  void ontextchanged(...) {    if (misinwatcher) return;    misinwatcher = true;     // text modifications here     misinwatcher = false; }
