Android Firebase-将新图像更新为当前用户会停止应用程序（不会崩溃）

问题描述

我试图通过单击图像视图来更改个人资料图片，并且能够裁剪图像然后将其存储到Firebase存储中。 但是，当添加新的图像文件时，程序停止并且无法单击任何内容。 应用程序甚至没有崩溃也没有关闭。 当我看到我的android显示器时，它一直在不断打印某些内容。 我认为这会在某处陷入某种无限循环。 有谁认识到这个问题？

PS当我更新新的配置文件图像时，我发现Firebase数据库中“用户”下的image子级来回变化非常快。 如果先前的图像是“ 1”，而我更新的图像是“ 2”，则它会像疯了一样变成1-> 2-> 1-> 2-> 1-> 2..。 他们彼此交换得非常快
