Memory utilization on the mobile app has a significant impact on the customer experience. If your app creates a lot of objects, then Garbage Collection (GC) process will be triggered frequently to evict unused objects. Even though Garbage Collection is an automatic process, however, frequent Garbage Collection consumes a lot of CPU + it will also pause the app. Frequent pauses can jank the app (i.e. stuttering, juddering, or halting). Thus, you need to understand how many objects your app is creating, how frequently Garbage collection is triggered, how much time it takes to complete, how much memory is reclaimed after every event. All this information is present in the runtime log messages. Whenever a GC event runs, a log line is printed in the runtime log messages. You can view those log lines through logcat. GC log line format varies based on whether app runs on Dalvik VM or Android Run Time (ART). In the earlier article, we saw how to analyze ART GC log line. In this article, let???s see how to analyze Dalvik GC log line.
