Android 4.3.47 setPathAsync NetworkOnMainThreadException

【版本信息】

4.3.47

【平台信息】

Android 原生

【预期的表现】

PAG加载不报错。

【实际的情况】

使用PAGImageView的setPathAsync()异步加载网络pag，加载成功后调用play()播放动画。
setPathAsync(url) { pagFile ->
post {
onComplete()
play()
}
}

但是在Firebase上有NetworkOnMainThreadException报错，如下：

看了下流程，play()调用了animator.start()，触发了flush()操作，然后内部判断_composition为空又去网络重新下载，按理说setPathAsync返回成功肯定是资源文件已经有了。
