python+minicap（二）

一、push文件至手机中

minicap 的使用有很强的针对性，针对不同架构的CPU和SDK制作了不同的 "minicap" 和 "minicap.so" 文件。

获取CPU版本

$ABI=adb shell getprop ro.product.cpu.abi

获取SDK版本

$SDK=adb shell getprop ro.build.version.sdk

1、有一种方法可以成功，可以截图成功的操作：通过adb shell进到手机对应的目录下/data/local/tmp目录下，执行 $LD_LIBRARY_PATH=/data/local/tmp /data/local/tmp/minicap -P 1080x1920@1080x1920/0 -s > /mnt/sdcard/tmp.jpg 命令就可以，然后再将截图Pull到win电脑中。
2、如果在dos命令提示 符中，直接执行adb shell LD_LIBRARY_PATH=/data/local/tmp /data/local/tmp/minicap -P 1080x1920@1080x1920/0 -s > c:\ tmp.jpg ，生成的图片就显示已损坏。

adb shell "$LD_LIBRARY_PATH=/data/local/tmp /data/local/tmp/minicap -P 1080x1920@1080x1920/0 -s" > c:\ tmp.jpg
另外这是一个shell命令，直接把结果导出到windows端会存在文件头解析的问题（因为手机是linux和windows的编码格式有一些差别导致的）
