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

 1 public class DefaultExceptionHandler implements UncaughtExceptionHandler {   

 2 

 3    private Context act = null;  

 4    crashInterface crashInterface;

 5    @Override

 6    public void uncaughtException(Thread arg0, Throwable arg1) {

      Intent sIntent=new Intent(act , CrashActivity.class);

27        sIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//必须带上

28        act.startActivity(sIntent);

29 //       crashInterface.finsh();

30  //此处异常

31        return;

32    }

33    

34    public DefaultExceptionHandler(Context act,crashInterface  crashInterface) {  

35         this.crashInterface=crashInterface;

36        this.act = act;  

37     }  



47 }

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)); 

    }
