17.8 MiB heap allocation for a simple "Hello World" project?
android, eclipse-memory-analyzer, garbage-collection, heap-memory
Solution
And added a 56 KiB background image.
No, you added a 56 KiB file that you are using as a background image.
The actual heap space consumed by a bitmap is three bytes per pixel. With a ~6MB bitmap (per your MAT screen), you are running your app on a fairly high resolution device or emulator (1080p should result in ~8MB, IIRC).
Problem
I am guessing there is an obvious answer here... I am left confused with this one: Why do I get 17.8 MiB heap memory allocated when all I have done is: - Created a simple "Hello World" project with Eclipse's New Project option. - And added a 56 KiB background image. If I take out the `android:background="@drawable/background4"` line, the allocated memory goes down to 11.9 MiB. - Is this normal for the system to allocate this much memory? Should I worry about it? - What would take up this much of the heap? I also ran a MAT report on it, but I am not sure what conclusion to draw from it: Thanks in advance,
