The memory consumtion rises indefinetly and I doubt that a memory consumtion of nearly 1GB is normal. My app is a very image-heavy app that uses Picasso as the image library. But even with the .networkPolicy(NetworkPolicy.NO_CACHE) modifier, the memory footprint stays roughly the same. Another issue that is visible on this image is the "Others" category that never gets garbage collected.
Is there a way to lower the memory usage of the "Graphics" or the "Others" category?
This is expected behavior bc garbage collection only applies to Java memory (memory controlled by the JVM). Also note that the Android Studio Profiler is a purely a visualization tool--it shows the breakdown of memory usage, but minimizing such usage is up to the developer.
