Android App性能测试

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，如果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

Uptime: 5159608 Realtime: 5159608

可以通过过滤信息 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
