This approach allows most of the RAM pages allocated forįramework code and resources to be shared across all app processes. Loads and runs the app's code in the new process. The Zygote process starts when the system boots and loads common ItĮach app process is forked from an existing process called Zygote. In order to fit everything it needs in RAM,Īndroid tries to share RAM pages across processes. In that circumstance, the garbage collector executes multiple garbageĬollection events and can degrade the performance of your app.įor more general information about garbage collection, see Innermost part of a for-loop during each frame of an alphaīlending animation, you might pollute your memory heap with a More often or make them last longer-than-normal.įor example, if you allocate multiple objects in the Recommended 16ms threshold for efficient and smooth frame rendering.Īdditionally, your code flow may perform kinds of work that This increase can potentially push code execution in your app past the Like an animation or during music playback, it can increase processing time. Garbage collection occurs in the middle of an intensive processing loop The system stops executing the process and begins garbage collection. The system has a running set of criteria for determining when to perform When a garbage collection event occurs from within your code. The duration of the garbage collectionĭepends on which generation of objects it's collectingĪnd how many active objects are in each generation.Įven though garbage collection can be quite fast, it can stillĪffect your app's performance. To fill up, the system executes a garbage collectionĮvent in an attempt to free up memory. To an older generation, followed by a permanent generation.Įach heap generation has its own dedicated upper limit on the amount When an object stays active long enough, it can be promoted Reclaim the resources used by those objects.Īndroid’s memory heap is a generational one, meaning that there areĭifferent buckets of allocations that it tracks,īased on the expected life and size of an object being allocated.įor example, recently allocated objects belong in the Young generation. Garbage collection has two goals:įind data objects in a program that cannot be accessed in the future and The mechanism for reclaiming unused memory It frees it back to the heap, without any intervention from the programmer. That a piece of memory is no longer being used by the program,

This page explains how Android manages app processes and memoryĪllocation.

Mmapped in without modification, such as code,Ĭan be paged out of RAM if the system wants to use that memory elsewhere. Object references that the app holds, making the memory available to the The only way to release memory from an app is to release New objects or touching mmapped pages-remains resident in RAM andĬannot be paged out. The Android Runtime (ART) and Dalvik virtual machine use
