Android安全技术揭秘与防范

在一些特定的工作场景中，我们把数据及时写出磁盘，而不是暂时保存在系统的文件缓存区，防止掉电导致数据丢失 /** * Force all system buffers to synchronize with the underlying * device. This method returns after all modified data and * attributes of this FileDescriptor have been written to the * relevant device(s). In particular, if this FileDescriptor * refers to a physical storage medium, such as a file in a file * system, sync will not return until all in-memory modified copies * of buffers associated with this FileDescriptor have been * written to the physical medium. * * sync is meant to be used by code that requires physical * storage (such as a file) to be in a known state For * example, a class that provided a simple transaction facility ……

今天跟大家分享一下，如何通过Python实现一个轻量级的库来获取电脑上连接的Android设备信息，为什么说轻量呢因为整个库也就4KB，相比其他诸如Appetizer这样动辄就8MB多的库要轻很多，而且也基本满足项目中的需求。 这个库只有一个文件，通过封装Android的ADB命令实现，返回的是一个包含所有设备信息的标准json格式的列表方便解析，下面简单介绍一下： 检查环境变量 # 判断是否设置环境变量ANDROID_HOMEif "ANDROID_HOME" in os.environ: command = os.path.join( os.environ["ANDROID_HOME"], "platform-tools", "adb")else: raise EnvironmentError( "Adb not found in $ANDROID_HOME path: %s." % os.environ["ANDROID_HOME"]) 命令执行 class Shell: def __init__(self): pass @static……
