[Android][Bug] Memory grows over time in sample app

[kesha-antonov]

Hello!

I've noticed that memory grows over time with no reason. In my app I see significant growth. In sample app is lower. But still.
It grows over limit. And then starts again and never stops to grow.

What's the reason?

Here's video:

@kesha-antonov Can you try running 0.50.0-rc.2 and see if it still happens? I've been running the sample app (with constant but simple network calls) on 0.50.0-rc.2 for > 12 hours and my memory graph still looks pretty flat.

Also, wondering if you're running the profiler with the debug build? If you are, chances are that the memory usage will keep growing.

@yinghang Ok thanks! I will try latest master

I've tried both. Memory grows. In sample app slowly. In my production app faster

With recent master will try tomorrow

@yinghang BTW your graph looks like a saw. It means memory constantly grows and garbage collected. You think it's okay? I don't have much experience with java so not sure.

[yinghang]

I think so, I think it's due to the API call that I'm making every 5 seconds.

Maybe related #16732

Are you using WebSockets in your app? If not I'm afraid that they're probably unrelated. Also, did you get to build your app with the release variant? App memory will grow continuously in debug mode.
