**1. 相关代码：**

由Activity发Intent跳转引起的IllegalStateException异常。

public static Intent getApkFileIntent( Context context,String param ) {
    
        Intent intent = new Intent();
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.setAction(android.content.Intent.ACTION_VIEW);
        Uri uri = Uri.fromFile(new File(param ));
        intent.setDataAndType(uri,"application/vnd.ms-word");
        context.startActivity(intent);
        return intent;
    }

**2. 错误信息：**

。。。

**3. 原因分析**：  
从log来分析，很明显，是由于TestActivity发了Intent,act=android.intent.action.VIEW dat=file:///storage/emulated/0/aaa.doc typ=application/vnd.ms-word flg=0x10000000 \},  
从Intent的参数来看，是要用另外一个app打开word文档。但是，遗憾的是，整个手机中就没有打开这种类型的app，最终导致IllegalStateException异常。  
  
  
**4. 解决办法：**  
1. 这种异常，需要捕获，并抛出异常，提示用户“此文档无法打开”。  
  
  
2. 在手机上安装一个可以打开word文档的app。  
  
  
3. 将Intent相关参数改为"\*/\*",如：

intent.setDataAndType(uri,"*/*");
