Android应用程序在模拟器上工作而不是设备

时间：2014-10-07 14:43:35

标签： android json

美好的一天，我有一个巨大的惊喜。我的应用程序在模拟器上运行时工作，但在我在真实设备上尝试时崩溃。我不明白怎么会发生这种情况。我正在尝试将数据插入到DATABSE。

出于某种原因，只有在我使用设备时才会出现错误。 下面是错误日志和代码。

请原谅我，如果这是一个小错误而且我在问。我已经尝试了几个小时，仍然对于如何在仿真器上而不是在真实设备上工作而感到困惑。

答案 0 :(得分：-1)

你用过，

if (success == 1) 
{
      // successfully created product
      Intent i = new Intent(getApplicationContext(), MyActivity.class);
      startActivity(i);

      // closing this screen
      finish();
  } 
  else 
  {
     // failed to create product
     Intent i = new Intent(getApplicationContext(), RegisterActivity.class);
     startActivity(i);

     // closing this screen
     finish();
   }

getApplicationContext()是Context上的方法，AsyncTask不会从Context继承。

而是尝试其他方式来获取上下文 - getting context in AsyncTask
