    private void getAppData() {

        Intent intent=getIntent();

        if(intent.getFlags()==101){     //这句出错 ，101不知道是什么 意思 


            Bundle bundle=intent.getExtras();

            Log.i("tag", data_str);

        }

    }

这个提示的意思是，用 Intent 的静态常量来代替这个数值101。后面列举出来了一系列常量，必须是其中一个。
源码里面的常量具体值一般是16进制，把101转成16进制，就能找到对应的常量了
