Cannot resolve symbol 'proxy_port'

这个错误是在编译或运行代码时出现的，通常表示你在代码中引用了一个未定义或不可访问的变量或方法。根据错误信息来看，'proxy_port'这个符号无法解析，可能是因为你没有定义或者没有导入相应的类。

首先，你需要检查你的代码中是否有与'proxy_port'相关的变量或方法。如果有，确保这些变量或方法的命名是正确的，并且已经在适当的位置定义。

此外，你还需要检查是否导入了必要的类或包来使用这个变量或方法。在Java中，你需要使用import语句将所需的类导入到你的代码中，以便可以正常访问其中的成员。

如果以上的方法都没有解决问题，那么你可能需要查看你使用的库或框架的文档，以了解如何正确使用'proxy_port'和相关的设置。

如果你能提供更多的上下文或代码片段，我可以更具体地帮助你解决这个问题。

Cannot resolve symbol 'ACTION_USB_STATE'

`ACTION_USB_STATE` is a constant defined in the `android.hardware.usb.UsbManager` class. It is used to broadcast USB state changes. If you are getting the error "Cannot resolve symbol 'ACTION_USB_STATE'", it means that you haven't imported the necessary class or there might be an issue with your Android project configuration.

To resolve this issue, make sure you have the following import statement at the top of your Java file:

import android.hardware.usb.UsbManager;

Also, ensure that you have the necessary permissions declared in your AndroidManifest.xml file:

<uses-permission android:name="android.permission.USB_PERMISSION" />

If you have already done these steps and still encounter the issue, try cleaning and rebuilding your project or restarting your IDE.

Cannot resolve symbol 'WRITE_EXTERNAL_STORAGE'

This error typically occurs when you are trying to use the WRITE_EXTERNAL_STORAGE permission in your Android application but have not declared it in the AndroidManifest.xml file.

To resolve this error, add the following line of code to your AndroidManifest.xml file:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

This will declare the WRITE_EXTERNAL_STORAGE permission and allow your application to write to external storage.
