Android_Mat_工具使用

抓取hprof

adb shell am dumpheap [pid] /data/local/tmp/[pid].hprof
hprof-conv 3725.hprof 3725.mat.hprof

adb shell am dumpheap 9384 /data/local/tmp/9384_02.hprof

使用MAT

这里需要修改,改为144就可以了.

private static final int DUMPSYS_ENTRY_COUNT_LIMIT = 14400; // 12 hours on 3 second poll

查找下面这段LOG

fling expand=false aboveThreshold=false thresholdNeeded=false screenOnFromTouch=false
