Downgrade minSdk to 23

Archives are currently not supported on API < 28.
Fallback image decoder may have low performance.

minsdk should never lower than 26 aka Oreo since
Bitmap are stored in dalvik heap on these platforms

Doing so is meaningless unless you'd like infinity OOM
I suggest using hippo's

Please take a look

And that's why hippo use a external 'image' object and render it through OpenGL
We want bitmap data stored (at least...) in native heap

My phone was broken and had to use an old phone (API 25) temporarily, it's not intended to bring full support to 23.
Surprisingly I didn't get much OOM with that 2G RAM device.

It doesn't look like it's going to OOM, except when loading GIFs.

Maybe I just remove GIF support completely.

It somewhat helps, but does not solve the issue.
