If you're experiencing slow performance issues with your Android app or if Instant Run features in Android Studio stop working randomly, it could be due to memory leaks. Java's garbage collector periodically checks for unused objects and removes them, but a memory leak occurs when there are objects not in use that the garbage collector cannot recognize, leading to reduced available memory and unexpected results. To detect memory leaks, you can use tools like Android Studio's Memory Monitor or third-party libraries like Leak Canary, which allow you to send notifications when a memory leak is detected. Additionally, static analysis tools like Infer can help identify potential issues such as null pointer exceptions and resource leaks. By using these tools and techniques, you can identify and fix memory leaks in your app, improving its performance and stability.
