一、内存

1、查看单个应用App最大内存限制

Command：adb shell “getprop|grep heapgrowthlimit”

C:\Users\hujiachun>adb shell "getprop|grep heapgrowthlimit"
[dalvik.vm.heapgrowthlimit]: [128m]

128M是单个APP最大内存限制，假设Dalvik Heap 的Pss大于128。就会报内存溢出

2、监控某个App内存

Command：adb shell dumpsys meminfo com.meizu.mstore

C:\Users\hujiachun>adb shell dumpsys meminfo com.meizu.mstore
Applications Memory Usage (kB):
Uptime: 5159608 Realtime: 5159608** MEMINFO in pid 13914 [com.meizu.mstore] **Pss  Private  Private  Swapped     Heap     Heap     HeapTotal    Dirty    Clean    Dirty     Size    Alloc     Free------   ------   ------   ------   ------   ------   ------Native Heap        0        0        0        0    28672    18939     9732Dalvik Heap    45029    44068        0        0    60986    56981     4005Dalvik Other      680      680        0       60Stack      492      492        0       36Other dev        6        0        4        0.so mmap     2454      172      284     1728.apk mmap      509        0      228        0.ttf mmap      854        0      464        0.dex mmap     6240        0     6236        0.oat mmap     5925        0     2564        0.art mmap     2951     1748      716        8Other mmap      137        4      104        0EGL mtrack    14960    14960        0        0GL mtrack    59264    59264        0        0Unknown    16331    16256        0      816TOTAL   155832   137644    10600     2648    89658    75920    13737ObjectsViews:     1242         ViewRootImpl:        1AppContexts:        4           Activities:        1Assets:        4        AssetManagers:        4Local Binders:       31        Proxy Binders:       29Parcel memory:       15         Parcel count:       60Death Recipients:        1      OpenSSL Sockets:        0SQLMEMORY_USED:      430PAGECACHE_OVERFLOW:      116          MALLOC_SIZE:       62DATABASESpgsz     dbsz   Lookaside(b)          cache  Dbname4       20             83       210/52/9  /data/data/com.meizu.mstore/d

能够通过过滤信息 得到Dalvik Heap 的Pss值。实时监控

二、CPU

Command：adb shell " dumpsys cpuinfo |grep com.meizu.mstore"

C:\Users\hujiachun>adb shell " dumpsys cpuinfo |grep com.meizu.mstore"1.3% 18957/com.meizu.mstore: 1% user + 0.2% kernel / faults: 171 minor

 1.3% 是总消耗CPU

user是用户消耗

kernel 是内核消耗
