How to use android studio profiler4/17/2023 ![]() ![]() ![]() When you first open the Memory Profiler, you’ll see a detailed timeline of your app’s memory use and access tools to force garbage collection, capture a heap dump, and record memory allocations. Record memory allocations during normal and extreme user interaction to identify exactly where your code is either allocating too many objects in a short time or allocating objects that become leaked.Several heap dumps over an extended period of time can help identify memory leaks. Dump the Java heap to see which objects are using up memory at any given time.Look for undesirable memory allocation patterns in the timeline that might be causing performance problems. ![]() To help prevent these problems, you should use the Memory Profiler to do the following: Then when the user returns to your app, it must restart completely. Eventually, the system is forced to kill your app process to reclaim the memory. This behavior can slow the rest of the system’s memory performance by forcing unnecessary garbage collection events. The delay could cause your app to skip frames and cause visible slowness.Įven if your app doesn’t exhibit slowness, if it leaks memory, it can retain that memory even while it’s in the background. However, if your app allocates memory faster than the system can collect it, your app might be delayed while the collector frees enough memory to satisfy your allocations. Click anywhere in the MEMORY timeline to open the Memory Profiler.Īndroid provides a managed memory environment-when it determines that your app is no longer using some objects, the garbage collector releases the unused memory back to the heap.If you’ve connected a device over USB but don’t see it listed, ensure that you have enabled USB debugging. Select the device and app process you want to profile from the Android Profiler toolbar.Click View > Tool Windows > Profiler (you can also click Profile in the toolbar).To open the Memory Profiler, follow these steps: It shows a real-time graph of your app’s memory use and lets you capture a heap dump, force garbage collections, and track memory allocations. The Memory Profiler is a component in the Android Profiler that helps you identify memory leaks and memory churn that can lead to stutter, freezes, and even app crashes. ![]()
