You can also get real-time hardware info. Build.* parameters are set during compilation of Android before even deploying it on hardware itself.

您还可以获得实时硬件信息。Build.* 参数在 Android 编译期间设置，甚至在将其部署到硬件本身之前。

You can access Linux real-time hardware info by reading /proc/* "files".

您可以通过读取 /proc/* "files" 来访问 Linux 实时硬件信息。

You can do that with https://stackoverflow.com/a/3528239/997381

你可以用https://stackoverflow.com/a/3528239/997381做到这一点

Simply as command put cat /proc/cpuinfo.

就像命令一样cat /proc/cpuinfo。

You can test this with adb shell, and you don't need root permissions.

您可以使用 进行测试adb shell，并且不需要 root 权限。

The "Build" class in android.os looks like it will contain some of the information you require

android.os 中的“Build”类看起来将包含您需要的一些信息

use it as

用它作为

string build = Build.VERSION.DEVICE;

android Hardware Info

安卓硬件信息
