Question

我尝试了adb shell top，但它提供了太多详细信息。

我需要的只是总可用内存。如何通过亚行获得？

Answer 1

为什么不内置::

$ adb shell "cat /proc/meminfo"

大多数手机缺少free实用程序以及更多buzybox。另一方面，/proc/meminfo是Linux的组成部分。

Answer 2

最干净＆＃34;清洁＆＃34;我到目前为止发现的方式是adb shell vmstat

它提供如下信息：

procs  memory                       system          cpu
 r  b    free mapped   anon   slab    in   cs  flt  us ni sy id wa ir
 1  0   99120  55400 618680  25600  2207 4089    0   6  0  9 84  0  0

其中，99120是以KB为单位的可用内存。

如何使用busybox？

adb shell busybox free -m
             total         used         free       shared      buffers
Mem:           741          503          237            0            5
-/+ buffers:                498          242
Swap:            0            0            0
