about why Android force Close appears and how to fix it

There are many reasons for force close, such as null pointers, classes are not found, resources are not found, and even the order errors used by the Android API can be caused (such as Setcontentview () Findviewbyid () operation)

Force Close some people say that it is possible to use the application to completely exit and deliberately cause this problem, so that the program is forced to shut down, which I still do not use.

How to avoid ejecting the Force close window can implement the Uncaughtexception method code for the Thread.uncaughtexceptionhandler interface as follows:

Import Java.lang.Thread.UncaughtExceptionHandler;
Import android.app.Application;
public class MyApplication extends application implements Uncaughtexceptionhandler {
@Override
public void OnCreate () {
  TODO auto-generated Method Stub
  Super.oncreate ();
}

@Override
public void uncaughtexception (thread thread, Throwable ex) {
  Thread.setdefaultuncaughtexceptionhandler (this);  
}

}

To add, you want which thread can handle the uncaught exception, Thread.setdefaultuncaughtexceptionhandler (this); This code will be executed once in that thread.
