【问题描述】：
我正在尝试裁剪image（我从图库中选择或从我的相机中拍摄）并将其传递给另一个activity，后者应该将image 上传到我的firebase 存储。
起初（没有裁剪图像）一切都很顺利。我能够通过并上传image...但是在将图像裁剪代码添加到我的onActivityResult 之后，它只是在按下“裁剪”后关闭了 imageCropActivity 并跳回了我的 MainActivity。
我试过了，但我真的不知道为什么会这样。也许我错过了一些东西。有任何想法吗？
对于图像裁剪，我正在使用这个库：https://github.com/ArthurHub/Android-Image-Cropper
