adb 打印终端中内存使用情况的方法

来源：互联网发布：还珠格格小燕子知乎编辑：程序博客网时间：2024/05/21 06:55

在调试一些内存相关的问题时，我们通常需要实时打印出当前系统中所使用的内存信息。

下面提供两种方法来查看这些信息。

方式一，使用 adb shell dumpsys meminfo

使用示例：

C:\Users\Administrator>adb shell dumpsys meminfoApplications Memory Usage (kB):Uptime: 14868066 Realtime: 21560285Total PSS by process:    35958 kB: system (pid 463)    30518 kB: com.bbk.launcher2 (pid 824)    26253 kB: com.android.systemui (pid 630)    20983 kB: com.android.settings (pid 7366)    10239 kB: com.android.phone (pid 706)     9986 kB: com.tencent.qqpimsecure (pid 893)     9326 kB: com.iqoo.ime.service (pid 685)     8962 kB: android.process.media (pid 796)     7418 kB: com.sohu.sohuvideo:log_service (pid 6695)     7140 kB: com.ting.mp3.oemc.android:pushservice_v1 (pid 6502)     7074 kB: com.mediatek.bluetooth (pid 716)     7062 kB: com.sina.weibo (pid 2429)     7033 kB: android.process.acore (pid 1150)     6288 kB: com.sina.weibo.servant (pid 5979)     5898 kB: com.eg.android.AlipayGphone (pid 3473)     5435 kB: com.android.ActivityNetwork (pid 6621)     5327 kB: com.tencent.mm (pid 6553)     5281 kB: com.android.bbkmusic (pid 1322)     4559 kB: com.netease.pris:push (pid 7126)     4445 kB: com.android.mms (pid 6463)     4392 kB: com.mediatek.mdlogger (pid 725)     4347 kB: com.baidu.map.location:remote (pid 843)     4275 kB: com.mediatek.mobilelog (pid 7063)     4254 kB: com.android.contacts (pid 857)     3993 kB: com.bbk.appstore (pid 7262)     3854 kB: com.mediatek.MediatekDM (pid 6281)     3667 kB: com.android.keychain (pid 7276)     3623 kB: com.baidu.map.location (pid 784)     3387 kB: com.mediatek.atci.service (pid 7110)     3359 kB: com.android.bbksoundrecorder (pid 746)     3265 kB: com.svox.pico (pid 7332)     3261 kB: com.android.defcontainer (pid 6448)Total PSS by OOM adjustment:    35958 kB: System               35958 kB: system (pid 463)    63631 kB: Persistent               26253 kB: com.android.systemui (pid 630)               10239 kB: com.android.phone (pid 706)                7074 kB: com.mediatek.bluetooth (pid 716)                7033 kB: android.process.acore (pid 1150)                5281 kB: com.android.bbkmusic (pid 1322)                4392 kB: com.mediatek.mdlogger (pid 725)                3359 kB: com.android.bbksoundrecorder (pid 746)    29945 kB: Foreground               20983 kB: com.android.settings (pid 7366)                8962 kB: android.process.media (pid 796)    27841 kB: Perceptible                9986 kB: com.tencent.qqpimsecure (pid 893)                9326 kB: com.iqoo.ime.service (pid 685)                4275 kB: com.mediatek.mobilelog (pid 7063)                4254 kB: com.android.contacts (pid 857)    14255 kB: A Services                7140 kB: com.ting.mp3.oemc.android:pushservice_v1 (pid 6502)                3854 kB: com.mediatek.MediatekDM (pid 6281)                3261 kB: com.android.defcontainer (pid 6448)    30518 kB: Home               30518 kB: com.bbk.launcher2 (pid 824)    27087 kB: B Services                7418 kB: com.sohu.sohuvideo:log_service (pid 6695)                6288 kB: com.sina.weibo.servant (pid 5979)                5435 kB: com.android.ActivityNetwork (pid 6621)                4559 kB: com.netease.pris:push (pid 7126)                3387 kB: com.mediatek.atci.service (pid 7110)    41627 kB: Background                7062 kB: com.sina.weibo (pid 2429)                5898 kB: com.eg.android.AlipayGphone (pid 3473)                5327 kB: com.tencent.mm (pid 6553)                4445 kB: com.android.mms (pid 6463)                4347 kB: com.baidu.map.location:remote (pid 843)                3993 kB: com.bbk.appstore (pid 7262)                3667 kB: com.android.keychain (pid 7276)                3623 kB: com.baidu.map.location (pid 784)                3265 kB: com.svox.pico (pid 7332)Total PSS by category:   145990 kB: Dalvik    44471 kB: Unknown    35557 kB: Other dev    24404 kB: .so mmap    14348 kB: .dex mmap     3830 kB: Other mmap     1214 kB: .apk mmap      524 kB: Native      424 kB: .ttf mmap       68 kB: Ashmem       32 kB: Cursor        0 kB: .jar mmapTotal PSS: 270862 kB      KSM: 0 kB saved from shared 0 kB           0 kB unshared; 0 kB volatile

方式二：使用 adb shell procrank 命令

使用示例：

方式二中能看出当前系统总共有多少内存，有多少空闲，有多少buffer，缓存等信息

当前使用这两种方式的前提是 adb remount 能够成功。

可以通过 adb shell kill PIDNumber 来杀死你想杀死的后台进程来模拟某种 bug 的复现条件。

譬如 adb shell kill 630 就能杀死 com.android.systemui 这个进程，有兴趣的可以尝试一下，盯住手机屏幕看下有什么反应……

adb shell ps 可以查看当前终端中的进程信息

那么如何在代码中判断当前的硬件系统有多少的 RAM 呢？

使用下面代码可以奏效：

在 Framework ProcessList.java 中有如下代码可用：

     ProcessList() {        MemInfoReader minfo = new MemInfoReader();        minfo.readMemInfo();        mTotalMemMb = minfo.getTotalSize()/(1024*1024);     }

这个可以用于 app 层来适配不同内存配置的机型。
