1安卓笔记 异常捕捉

在程序崩溃的时候 ，捕捉异常

步骤  首先在 activity的oncreat中调用  Thread.setDefaultUncaughtExceptionHandler(new DefaultExceptionHandler( this.getApplicationContext(),crashInterface)); 
        实现一个继承UncaughtExceptionHandler的子类

public class DefaultExceptionHandler implements UncaughtExceptionHandler {   

   private Context act = null;  
   crashInterface crashInterface;
   @Override
   public void uncaughtException(Thread arg0, Throwable arg1) {
      Intent sIntent=new Intent(act , CrashActivity.class);
       sIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//必须带上
       act.startActivity(sIntent);
//       crashInterface.finsh();
 //此处异常
       return;
   }
   
   public DefaultExceptionHandler(Context act,crashInterface  crashInterface) {  
        this.crashInterface=crashInterface;
       this.act = act;  
    }  

}

在需要捕获异常的activity 中oncreat

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        view= getLayoutInflater().inflate(R.layout.activity_main, null);  
        
        view.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION|View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
        setContentView(view);
    
        crashInterface  crashInterface=new crashInterface() {
            
            @Override
            public void finsh() {
                // TODO Auto-generated method stub
                finish();
                Process.killProcess(Process.myPid());
             
            }
        };
        Thread.setDefaultUncaughtExceptionHandler(new DefaultExceptionHandler( this.getApplicationContext(),crashInterface)); 
    }
