Use try catch for complete activity

I know it's not proper programming but I wan't to trie it anyway. I wan't a whole activity to be put in try catch.

So I tried the following: Put all code and function calls in onCreate in try catch. But still it isn't caught. How can I do this? Maybe make the whole activity class throwable or something?

edit: logcat console added

create a class that implements java.lang.Thread.UncaughtExceptionHandler. then in your activity's onCreate() method call:

// register our own exception handler to the current thread
Thread.setDefaultUncaughtExceptionHandler(new YOUR_CLASS_HERE());

If you are trying to prevent Force Closes and catch them instead, I recommend more effort on optimizing the code and catching portions which will throw exceptions like parsing integers, etc. To wrap the whole activity simply will not work.
