error using mat2file

error opening trace file: No such file or directory (2)

error opening trace file: No such file or directory (2) 这个问题的出现因为android模拟器版本和项目api不一致导致。一般情况下是这个原因。改成一致的后就不出现这个错误了。

linux 下报错error 2 (No such file or directory)

一、分析这是不同系统编码格式引起的：在windows系统中编辑的.sh文件可能有不可见字符，所以在Linux系统下执行会报以上异常信息。二、解决1）在windows下转换：利用一些编辑器如UltraEdit或EditPlus等工具先将脚本编码转换，再放到Linux中执行。转换方式如下（UltraEdit）：File–>Conversions–>DOS->UNIX即可。
