Question

当我在Eclipse Emulator中的Android 4.4.2下运行此代码时，应用程序崩溃并找不到源代码错误。

在所有旧的Api版本（4.3等）上，代码运行没有任何问题。

出了什么问题？

public void begin_drawing(){
   running = true;     
   direct_thread = new Thread(){
          @Override
          public void run() {                                         
          while(running){

            try {
            Thread.sleep(500);                                                                                                                                              
            runOnUiThread(new Runnable() {
                 @Override
                 public void run() {
                 try {                    
                   int i = 0;                                                                                                                      
                 } catch (Exception e1) {    
                    e1.printStackTrace();
                 }  
                }
             });  

           } catch (Exception e) {
                e.printStackTrace();
           }
         }
      };
      };  
      direct_thread.start();      
  }

单步调试Line＆＃34; Thread.sleep（500）＆＃34;将执行，但＆＃34; int i = 0;＆＃34;不会打电话。

当我按F8（恢复）时，应用程序崩溃了。
