OutOfMemoryError

I get this error when I'm working in my app, not at the start app.
Nexus 5 (Android 5.1.1)

Any chance you have a large image you are trying to set as a View background?

[ilyamuromets]

I set only color and background-color values with your library.

[Shalom]

I see. What device are you using, and how much memory does it have available.

[ilyamuromets]

Nexus 5.
It happens when available 0-3% free memory. It shows logcat.

If I disable your library my app works without crashes.

The library has some memory consumption that is 'natural' to its work. As you can see from the stacktrace, there is a rendering of the background into a Bitmap, and that takes memory. The allocated Bitmap size in that case would be the size of the View you are trying to apply a background to. In case your device is that tight on memory, you should take that into account.

Saying that does not mean that the library cannot be improved :) In cases where the CSS only defines a color, and not an image or a gradient color, it can be modified to set the color directly on the View (instead of using a backgroud bitmap). This will take some work, and you are welcome to look into the code in case you are interested.

Thanks for the detailed answer!
Maybe there is a performance problem in my app.

I found steps to reproduce:
I set PixateFreestyle.setStyleClass(view, class) for a few view (about 8-10 views). My app starts with default.css then I click a button to download user.css from server and apply it. I edit user.css on server and click again a button to download. To apply new styles I use following PXStyleUtils.updateStyles(android.R.id.content, true).
After a few clicks on a button my app crashes with OutOfMemoryError.
