Preventing and detecting memory leaks in Android apps

Mobile applications are prone to memory leaks, which occur when objects that are no longer needed continue to consume memory due to retained references, leading to inefficient memory usage and potential app crashes. Developers can address this issue in Android apps using tools like the Android Profiler and LeakCanary, which help detect and prevent memory leaks by analyzing memory allocation and tracking object lifecycles. Common causes of memory leaks include improper use of context, static references, threaded code, and handler threads, all of which can retain unnecessary references to application components. To mitigate these leaks, developers should manage object lifecycles carefully, use weak references where appropriate, and ensure that threads and handlers are stopped or cleared when no longer needed. By implementing these best practices, developers can maintain efficient memory management and improve app stability.
