1、实现UncaughtExceptionHandler，在方法uncaughtException中处理没有捕获的异常。

public class GlobalException implements UncaughtExceptionHandler
{  
  private final static GlobalException myCrashHandler = new GlobalException();

  private GlobalException()
  {
  }

  public static synchronized GlobalException getInstance()
  {
    return myCrashHandler;
  }

  public void uncaughtException(Thread arg0, Throwable arg1)
  {
    Trace.Log("-------------caught Exception--");
  }
}

2、继承Application ，在其中调用Thread方法setDefaultUncaughtExceptionHandler，来捕获异常

代码：

public class MyApplication extends Application 
{
  public void onCreate() 
  {
    super.onCreate();
    GlobalException handler = GlobalException.getInstance();    
    Thread.setDefaultUncaughtExceptionHandler(handler);   
    
  }
}
