【解决方案1】：

读取日志。 onActivityResult 方法中的 NullPointException。 com.example.android.imageuploader.MainActivity.onActivityResult(MainActivity.java:56) 在

你的回答没有一点帮助..请解释一下
我猜，“数据”对象为空。

【解决方案2】：

如果有人仍然想知道，我遇到了这个问题，在我的情况下，这是因为意图不再返回图像的 Uri，而是返回图像位图作为额外的，因此您可以尝试检索位图从“OnActivityResults”意图（“数据”）额外并从此位图创建一个文件并使用它上传到firebase，为什么意图真的这样做了我不确定我使用的是文件提供程序然后将其删除，所以我认为正是在这个阶段改变了意图的行为。
