运行时，在手机上面已经安装了几自己编写的百度地图的测试示例，估计是因为文件功能用造成的。

反编译baidumapapi_v2_1_1.jar包发现在 com.baidu.platform.comapi.d.c.j(Unknown Source)这个方法如下：

private static String j(Context paramContext)
  {
    String str1 = null;
    String str2 = "imei.dat";
    String str3 = paramContext.getFilesDir().getAbsolutePath() + "/" + str2;
    File localFile = new File(str3);
    try
    {
      Object localObject;
      if (!localFile.exists())
      {
        B = false;
        str1 = k(paramContext);
        localObject = paramContext.openFileOutput(str2, 32768);
        ((FileOutputStream)localObject).write(str1.getBytes());
        ((FileOutputStream)localObject).close();
      }
      else
      {
        B = true;
        localObject = paramContext.openFileInput(str2);
        byte[] arrayOfByte = new byte[((FileInputStream)localObject).available()];
        ((FileInputStream)localObject).read(arrayOfByte);
        ((FileInputStream)localObject).close();
        str1 = new String(arrayOfByte);
        int i1 = str1.indexOf('|');
        str1 = str1.substring(0, i1);
      }
    }
    catch (Exception localException)
    {
      localException.printStackTrace();
    }
    return (String)str1;
  }

说明：

imei.dat这个文件已经存在，推测这个文件已经被创建，所以推测原因是受其他程序的影响。

解决办法：

删除手机上面的其他有关地图测试示例安装程序后，上面的异常情况就消失了。
