Memory leak with mBlurImage

[techtunde]

When enableBlurBackground() is set to true, if you monitor the memory of the application, you can see that memory goes up each time you do hover.show(), but doesn't go down when you do hover.hide(). If you look at the code for onAnimationEnd() for mGlobalDisappearAnimators, you see that the image within mBlurImage is not freed. I believe this is what causes the memory leak.

/** * 使用弱引用 */ private InvalidationLoop invalidationLoop = new InvalidationLoop(this);

private static class InvalidationLoop implements Choreographer.FrameCallback{
    private WeakReference<BlurLayout> blurLayoutWeakReference;

    public InvalidationLoop(BlurLayout blurLayout) {
        this.blurLayoutWeakReference = new WeakReference<>(blurLayout);
    }

    @Override
    public void doFrame(long frameTimeNanos) {
        try {
            if (blurLayoutWeakReference != null && blurLayoutWeakReference.get() != null) {
                BlurLayout blurLayout = blurLayoutWeakReference.get();
                blurLayout.invalidate();
                Choreographer.getInstance().postFrameCallbackDelayed(this, 1000 / mFPS);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}
