你可以创建一个实例并调用dumpMemoryInfo方法来获取并打印内存信息。 4. 分析内存Dump文件 无论你是通过ADB、Android Profiler还是代码获取的内存Dump文件,你都需要使用适当的工具来分析这些文件。Android Studio自带的Profiler可以直观地展示内存使用情况,而像Eclipse Memory Analyzer这样的工具则提供了更深入的分析功能,帮助...
/os/Debug.java#MemoryInfo 该类记录了应用内存使用的数据,具体赋值上文已经分析,在 Native 层解析 smaps 进行赋值。主要关注该类的局部变量含义,以及相关方法 TODO 相关局部变量说明 /** * Thisclass is used to retrievedvarious statistics about the memory mappings for this * process. The returned ...
这个信息是在app进程中打印出来的,最终该命令会执行到对应进程的如下接口: android/frameworks/base/core/java/android/app/ActivityThread.java@OverridepublicvoiddumpMemInfo(ParcelFileDescriptorpfd,Debug.MemoryInfomem,booleancheckin,booleandumpFullInfo,booleandumpDalvik,booleandumpSummaryOnly,booleandumpUnreachable,String...

dumpsysmemorydumpsysmemoryinfo 源码基于:Android R0. 前言其实,很久以前在 android 查看内存使用情况 一文中已经分析过dumpsysmeminfo,但最近在统计内存数据的时候发现怎么也对不上,所以重新分析了下源码,之前在 android 查看内存使用情况1.meminfo的起点dumpsysAMS 下的meminfo统计是通过dumpsys命令进行dump 的,这个是...
