Android内存泄露利器（内存统计篇） (转)

我们可以通过adb shell "dumpsys meminfo %curProcessName%"命令得到某个进程的内存使用情况。

getMemoryState.bat主要用于解析该命令返回的内存，得到NativeSize，DalvikSize，NativeAllocated，DalvikAllocated，NativePSS，DalvikPSS等。它把不同时期得到的数据按时间前后为顺序以逗号作为分隔符的排列输出到一个以进程名命名的文本文件，以便在excel中生产图表。

注意：需要把bat库genSerial.bat，getSubStr.bat放在子目录lib中。
