The maximum of heap memory size, then keep constant.
On the basis of original ART memory managements mechanism, a kind of ART EMS memory management process of optimization is proposed.This method is borrowed
Data statistics technology is helped, data are used by the internal memory for collecting each application, it is big to calculate the heap memory needed during each application operation
It is small, so as to just distribute the heap memory of suitable size when application starts, avoid applying during front stage operation due to internal memory
Frequent GC caused by deficiency and the operation of internal memory application release, so as to improve the speed of service of android applications, reduce power consumption.
The method of application memory Data Collection is as follows：
The internal storage data of application is collected in units of process corresponding to applying, starts to collect when process creation, process knot
Stop collecting during beam；
In the running of the corresponding process of application, when having detected that Activity, Service and Provider component creates
When building and exiting, the heap memory size of process is collected；
At the end of using corresponding process, average value and maximum that the process uses heap memory size are calculated；
Calculate the average value used using heap memory and maximum rule is as follows：
(1) if, the application be to use first, after exiting, according to the heap memory data of collection, calculate these data
Average value, as the average value used using heap memory；Maximum therein, the maximum used as heap memory；
(2) if, use first using non-, after this application is exited, take the maximum of last time and data of this collection
Maximum, the maximum as heap memory；The average of both the average value of last time and current average value, as the application heap
The average value of memory size.
The method of ART virtual machines optimization is as follows：
(1), when application is first in use, the default value using ART virtual machine parameters HeapStartSize is used as heap memory
Initial value, other values use ART virtual machines default configuration；
(2), when application non-first time in use, being used as ART virtual machine heap memories using the average value of heap memory using this
Initial value；
(3) its minimum average value of size in front stage operation, keeping heap memory, is applied；When heap memory deficiency needs
During application, GC operations are first carried out, if heap memory is still unsatisfactory for after GC operations, heap memory size is expanded into its maximum；
If the heap memory of application needs to exceed its maximum, the heap memory distribution mechanism given tacit consent to according to ART is handled；
(4), apply in front stage operation, after Memory recycle, when heap memory is less than average value with size, keep heap memory
Size is its average value；If greater than average value but it is less than maximum, then remains maximum；During more than maximum, write from memory by ART
Recognize mechanism processing；
(5) when, using backstage is shifted onto, GC operations are performed, and discharge its heap memory, using ART default memory administrative mechanisms.
(6), using from when switching to foreground from the background, if heap memory size is less than average value, setting heap memory size is
Its average value；If greater than average value but it is less than maximum, then it is its maximum to set heap memory size；If greater than maximum
Value, then keep constant.
The embodiment of the present invention, on based on ART memory management manufacturing basis, by data statistics technology, being calculated should
With the use size of heap memory, by improving ART EMS memory management process, different memory management plans of the connected applications in front and back
Slightly, avoid applying and occur interim card caused by frequent GC in front stage operation, accelerate the speed of service of application, reduce system
Power consumption.Simultaneously after using backstage is fallen back on, the internal memory of free time can be reclaimed in time again, avoid the waste of internal memory.
Next, labor Dalvik virtual machine is that how to solve low memory problem, and distribute interior
Deposit and how to manage.
Dalvik virtual machine realizes a dvmAllocObject function.Whenever Dalvik virtual machine is needed for object point
, will call function dvmAllocObject during with internal memory.For example, refer to when the interpreter of Dalvik virtual machine runs into a new
When making, it will call function dvmAllocObject.
It is the type clazz for finding the object to be created first, then on the realization of the interpreter of Dalvik virtual machine
Using it as parameter call function dvmAllocObject as the object storage allocation to be created.Another parameter ALLOC_
DONT_TRACK is the heap manager for telling Dalvik virtual machine, and the object to be distributed is a root collection object, it is not necessary to it
It is tracked.Because root collection object can be tracked processing automatically in GC
The internal memory that function dvmAllocObject call functions dvmMalloc distributes one piece of specified size from Java heap is given
The object newly created uses.If it is allocated successfully, then new wound is just first next initialized using grand DVM_OBJECT_INIT
Build the member variable clazz to object so that the object newly created can associate with some specific class, then recall
Function dvmTrackAllocation records current Memory Allocation information, to notify DDMS.
Simply one piece of memory address that function dvmMalloc is returned, this is no type.But due to each Java
Object all gets off from Object Similar integrals, and therefore, function dvmAllocObject can be by acquisition without in type
Counterfoil unsteady state operation is an Object object.
Object classes have two member variables：Clazz and lock.Wherein, member variable clazz type is
ClassObject, it corresponds to the java.lang.Class classes of Java layers, for the class belonging to description object.Member variable
Lock is a lock, exactly because there is this member variable, in Java layers, each object can use when lock.
After the definition that understanding of Object classes, before and after Java heap storage allocation, locking reconciliation is carried out to Java heap
Lock, avoid multiple threads while Java heap is operated.This be respectively by function dvmLockHeap and
DvmunlockHeap is realized.Really perform Memory Allocation operation be by call another function tryMalloc come
Complete.If be allocated successfully, current thread is recorded into the information such as the internal memory byte number of the distribution of work and number of objects.Otherwise
The information such as words, internal memory byte number and object that just record current thread is unsuccessfully distributed.After having these information, our cans
The memory usage information of application program count by instruments such as DDMS.
Finally, if storage allocation is successful, and parameter flags ALLOC_DONT_TRACK positions are arranged to 0, then need
The reference list that the object newly created is increased to inside Dalvik virtual machine is gone.It is stored in pair of this internal reference table
As that when performing GC, root collection can be added to and gone, so as to the survival for the object that correctly judges.
On the other hand, if storage allocation fails, then just the call function throwOOME OOM that dishes out is different in time
Chang Liao.
1. call function dvmHeapSourceAlloc distributes the internal memory for specifying size on Java heap.If it is distributed into
Work(, then the address that distribution obtains just is directly returned to caller.Function dvmHeapSourceAlloc is not changing
Memory Allocation is carried out on the premise of the current size of Java heap, this is the Memory Allocation action for belonging to lightweight.
2. if previous step Memory Allocation fails, at this time just need to perform a GC.But if GC threads
In operation, i.e. gDvm.gcHeap->GcRunning value is equal to true, then just directly invokes function
DvmWaitForConcurrentGcToComplete waits until that GC is performed and completed exactly.Otherwise, it is necessary to call function
GcForMalloc performs a GC, and parameter false represents not reclaim the object that soft reference object is quoted.
After 3.GC is finished, call function dvmHeapSourceAlloc attempts the Memory Allocation behaviour of lightweight again
Make.If it is allocated successfully, then the address that distribution obtains just is directly returned to caller.
4. if previous step Memory Allocation fails, must at this time consider first to be dimensioned to the current of Java heap
The Java heap maximum that Dalvik virtual machine is specified when starting, then carry out Memory Allocation.This is to pass through call function
DvmHeapSourceAllocAndGrow is realized.
5. if the success of call function dvmHeapSourceAllocAndGrow storage allocations, directly obtains distribution
Address be directly returned to caller.
6. if previous step Memory Allocation still fails, at this time just draw mean method.Call function again
GcForMalloc performs GC.Parameter true represents to reclaim the object that soft reference object is quoted.
7.GC is finished, and call function dvmHeapSourceAllocAndGrow carries out Memory Allocation again.This is most
Once make great efforts afterwards, success or not is all so far.
The Key Functions referred here to have three, be respectively dvmHeapSourceAlloc,
DvmHeapSourceAllocAndGrow and gcForMalloc.
