问题 I have been searching all over the net to try and find a way to catch all errors thrown by PHP (5.3) I have been reading through the documentation and it looks like set_error_handler is what I need but it doesn't get fatal/parse errors.

问题 I have a strange problem that I don't know how to face. My application uses a WebView to load a HTML app. It is a long and complex app, that also involves JavaScriptInterfaces. Lately I am getting Core Dumps in the native webcore module that kill the whole activity. It happens sometimes, but frequently, let's say 1 of every 5 times.
