Question

我想用裁剪库（https://github.com/ArthurHub/Android-Image-Cropper）选择一张照片，然后我希望它存储在Firebase中。

问题是，在我选择默认图库上的图片后，裁剪未打开且图片未保存在Firebase存储上。我犯了什么错？（我在代码中删除了不重要的东西）

好的，现在有效。我刚做了一个错字。而不是requestCode，它必须是resultCode

 if (requestCode == GALLERY_PICK && resultCode== RESULT_OK) {

图像不会存储在Firebase上，并且裁剪不会打开
