当应用于测试类时，此Rule执行测试方法后执行“getprop”设备命令并将其记录到外部存储器上的文件中。 默认文件位置通过getTestDir(String, String, int)检索。

The Rule logs the runtime build number, device name, build type, lcd density, cpu type, among many other device state attributes. When used in conjunction with a device lab it might assist in identifying trends in test failures for a subset of Android devices.

The pertinent information output by this rule typically doesn't change between tests, therefore, it is typically used manually by using the before() and after() methods in a RunListener.

Usage: \@Rule public LogDeviceGetPropInfoRule mLogDeviceGetPropInfoRule = new LogDeviceGetPropInfoRule();
