OutOfMemoryError

Hi, thanks for your awesome library.

I got a crash report of an OutOfMemoryError that was caused by Konfetti.

Device: Samsung Galaxy S7 Android version: 7.0 Trace:

Fatal Exception: java.lang.OutOfMemoryError: Failed to allocate a 4861960 byte allocation with 2445416 free bytes and 2MB until OOM

And my setup was:

binding.konfetti.build() 
    .addColors(Color.rgb(239, 115, 47), Color.rgb(161, 44, 46), Color.rgb(39, 71, 134), Color.WHITE) 
    .setSpeed(1f, 3f) 
    .setFadeOutEnabled(true) 
    .setTimeToLive(3000L) 
    .addShapes(Shape.RECT, Shape.CIRCLE) 
    .addSizes(new Size(12, 5)) 
    .setDirection(0.0, 180.0) 
    .setPosition(0, (float) binding.mainContent.getWidth(), -100F, -100F) 
    .stream(70, 3000L);

I just got one crash report, so I guess is some edge case.

Cheers!

It’s the only crash report that I got from that user and the only crash report where Konfetti was involved (Konfetti was running just one day). When the crash happened, the device had 24% of the RAM free. The screen where I was showing the confetti was pretty simple, I cannot think of anything that could be clogging up the memory there.

Closing this for now since I haven’t had more reports. Please open a new issue when the same problem reoccurs.
