Description

I use a infinitely animated webp with fresco, I add a listener to check when it repeat. I found that onAnimationStart() and onAnimationRepeat() was bean called more than once in the beginning.

Solution

Additional Information

Fresco version: [1.5.0 ]
Platform version: [All Android device]

-----------code----------
`DraweeController webpController = Fresco.newDraweeControllerBuilder()
.setUri(animatedWebpUri)
.setOldController(image.getController())
.setControllerListener(new BaseControllerListener() {
@Override
public void onFinalImageSet(String id, ImageInfo imageInfo, Animatable anim) {
if (anim != null && anim instanceof AnimatedDrawable2) {
((AnimatedDrawable2) anim).setAnimationListener(new AnimatedWebpListener() {
@Override
public void onAnimationStart(AnimatedDrawable2 drawable) {
SLog.e("webp","onAnimationStart -- ");
}

@Override
public void onAnimationStop(AnimatedDrawable2 drawable) {
SLog.e("webp","onAnimationStop -- ");
}

@Override
public void onAnimationReset(AnimatedDrawable2 drawable) {
SLog.e("webp","onAnimationReset -- ");
}

@Override
public void onAnimationRepeat(AnimatedDrawable2 drawable) {
SLog.e("webp","onAnimationRepeat -- ");
}

@Override
public void onAnimationFrame(AnimatedDrawable2 drawable, int frameNumber) {
SLog.e("webp","onAnimationFrame -- " + frameNumber);
}
});
anim.start();
}
}
})
.build();`
