How can you use Android Studio to find and fix memory leaks?

Analysing memory leaks in android studio is a pretty straight forward process. You just need to enable memory profiling in Android Studio, through which you can monitor the memory usage of your app and check for potential leaks. Select the process, that is most probably the package name of your app in Profiler window and clicking on Memory tab will show you the details of memory allocated and deallocated to you app over the course of time. You can record memory allocations, and capture heap dumps at multiple times and compare for potential memory leak of the objects. Analysing this data will give you a clear picture of where the memory leak is happening during your process.

Memory Profiler To open the Memory Profiler, follow these steps: Click View > Tool Windows > Profiler (you can also click Profile in the toolbar). Select the device and app process you want to profile from the Android Profiler toolbar. If you've connected a device over USB but don't see it listed, ensure that you have enabled USB debugging. Click anywhere in the MEMORY timeline to open the Memory Profiler. Alternatively, you can inspect your app memory from the command line with dumpsys, and also see GC events in logcat.

Use Android Profiler: Android Profiler is a tool built into Android Studio that allows you to monitor your app's CPU, memory, and network usage in real time. Open your project in Android Studio and click on the "Profiler" tab at the bottom. Run your app in debug mode and select the device/emulator you want to profile. Click on the "Memory" tab in the Profiler window to monitor memory allocations and deallocations.

Begin by activating a feature in Android Studio that tracks how your app manages memory, highlighting areas of concern. This tool displays a visual representation of memory handling, alongside options to document, manage, and analyze different aspects of memory usage.

Analyze Memory Profiler Data: In the Memory Profiler tab of Android Studio, you can analyze memory allocations over time. Look for trends such as continuously increasing memory allocations or objects that are not being garbage collected. Pay attention to memory allocations associated with activities, fragments, and other components that can potentially cause leaks.

Initiate a process that records your app's memory usage by tracking the creation and growth of objects while you simulate potential leak-causing actions. After recording, analyze the detailed report showcasing the objects' characteristics and connections, allowing for sorting and filtering to pinpoint potential issues.

Heap Dump Analysis: If you suspect a memory leak, take a heap dump while your app is running using Android Profiler. You can trigger a heap dump by clicking on the "Dump Java Heap" button in the Memory Profiler. Once the heap dump is captured, you can analyze it to identify objects that are not being garbage collected when they should be.

Take snapshots of your app's memory heap at different moments by using the designated feature, saving each state to a file for comparison. Analyze changes in memory usage by comparing these snapshots, focusing on the differences in object characteristics, to identify and address memory leaks, thus enhancing your app’s performance and user experience.

Use Memory Allocation Tracking: Android Studio's Memory Profiler also allows you to track memory allocations over time. You can enable "Allocation Tracking" to see where objects are being allocated and deallocated in your app. Look for instances where objects are being continuously allocated without being deallocated, which could indicate a memory leak. Fixing Memory Leaks: Once you've identified the source of the memory leak, fix it by correcting any references that are preventing objects from being garbage collected. Common causes of memory leaks include holding onto references to activities, contexts, views, or other long-lived objects. Use weak references or make sure to release references when they are no longer needed.

Memory Allocation Tracking: Utilize Android Studio's Memory Profiler to monitor where and when objects are created and destroyed in your app, identifying patterns where objects aren't being properly deallocated, hinting at potential memory leaks. Resolving Memory Leaks: After pinpointing a leak's source, resolve it by adjusting object references that hinder proper garbage collection, often caused by unnecessary retention of activities, contexts, or views, and employ weak references or ensure timely release of such references.
