在任何事情之前
1-选择文件使用这个或无论如何选择它
https://github.com/iPaulPro/aFileChooser
只需导入即可
2-不要忘记将此添加到清单
<\uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
3-不要忘记更改java代码中的uri和php代码中的文件夹名称
4-只需复制并通过此代码即可使用我尝试过并且可以 100% 工作
