Recommended that you trust the GC and avoid requesting explicit GCs if possible. The garbage collection was explicitly requested by an app, for instance, byĬalling #gc()} or #gc()}. In this case, the garbage collection occurred in the allocating thread. The GC was initiated because your app attempted to allocate memory when your heap I/art : Explicit concurrent mark sweep GC freed 104710(7MB) AllocSpace objects, 21(416KB) LOS objects, 33% free, 25MB/38MB, paused 1.230ms total 67.216msĪ concurrent GC which does not suspend app threads. I/art: () AllocSpace Objects, () LOS objects,Explicit GCs are always logged.ĪRT includes the following information in its garbage collection log messages: If the app is not in a pause perceptible process state, More precisely, if the GC pause exceeds than 5ms or Printed when they are they are deemed slow. Unlike Dalvik, ART doesn't log messages for GCs that were not explicitly requested. If this value continues to increase, you may have Concurrent pause times show two pauses: one at theÄ«eginning of the collection and another near the end.Īs these log messages accumulate, look out for increases in the heap stats 3571K/9991K} value in the above example). Larger heaps will have larger pause times. Percentage free of the heap and (number of live objects)/(total heap size).Ä®xternally allocated memory on API level 10 and lower (amount of allocated memory) / (limit at The amount of memory reclaimed from this GC. A GC for externally allocated memory (such as the pixel data stored in This happens only on API level 10 and lower (newer versions allocate everything in the Dalvik Should avoid calling and instead trust the GC to run when needed). Reasons that may appearĪ concurrent GC that frees up memory as your heap begins to fill up.Ī GC caused because your app attempted to allocate memory when your heap wasĪlready full, so the system had to stop your app and reclaim memory.Ī GC that occurs when you request to create an HPROF file to analyze your heap.Īn explicit GC, such as when you call #gc()} (which you What triggered the GC and what kind of collection it is. In Dalvik (but not ART), every GC prints the following information to logcat:Ä/dalvikvm: , , , Ä/dalvikvm( 9050): GC_CONCURRENT freed 2049K, 65% free 3571K/9991K, external 4703K/5261K, paused 2ms+2msThe logcat output is also available in theÄevice Monitor or directly in an IDE such as Android Studio. Sometimes when a GC occurs, a message is printed to The simplest place to begin investigating your appâs memory usage is the runtime log messages. Only way to be certain your app is using as little memory as possible is to analyze your appâs Switch between apps, it is important that your app does not needlessly consume memory when the userÄ®ven if you follow all the best practices for Managing Your App Memory duringÄevelopment (which you should), you still might leak objects or introduce other memory bugs. In order to provide a stable user experience that allows the system to quickly Routine garbage collection (GC), this doesnât mean you can ignore when and where your app allocates and Random-access memory (RAM) your app uses.

If the Game Bar doesnât appear, head to Settings > Gaming > Xbox Game Bar. To find it, open the Xbox Game Bar overlay by pressing Windows+G. However, you can âpinâ it to your desktop and make it appear over all other windows-desktop applications and PC games alike. This floating window is normally found in the Game Bar overlay itself. Windows 10âs Game Bar is a built-in overlay with all kinds of useful tools for gamers (and non-gamers,) including a performance usage graph.

So, if you want to change the graph to another one-for example, to change from CPU to GPU usage statistics-double-click the graph window, select a different graph in the sidebar, and doube-click the graph again.Ä«y the way, you can also double-click anywhere the left pane to see the left pane in a smaller floating window.
