英文:
Running Android Studio Volley in different API levels
问题
我制作的应用程序在不同的API级别上运行，但Volley库只能在API级别26上运行。
当我尝试在我的手机（Android 9）上登录应用程序时，我感到困惑，但稍后型号的手机可以正常工作。后来我发现，只能在Android 8手机（API级别26）上登录。我测试了多个具有不同API级别的虚拟设备，发现只有API级别26允许我登录，其他的都不起作用。我想知道如何使Volley库在API级别26及更高版本上工作。
编辑：这是我的一个大错误，但我现在已启用了错误日志并发现了以下问题。

英文:
The app I made ran on different API levels but the volley library only works API level 26.
I was puzzled when I can't login in the app using my phone (android 9) but a later model works just fine. I found out that I can only login in Android 8 phones (API level 26). I tested multiple virtual devices with different API levels and API level 26 let's me login and the rest just doesn't work. I was wondering how can I make volley library work on API level 26 and higher.
Edit: It was a big mistake for me but I now enabled the log for errors and I found these.

在你的应用程序标签中添加以下行：
<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
<uses-permission android:name="android.permission.INTERNET" />
<application
...
android:usesCleartextTraffic="true"
...>
...
</application>
</manifest>
英文:
Add this line in your application tag
<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
<uses-permission android:name="android.permission.INTERNET" />
<application
...
android:usesCleartextTraffic="true"
...>
...
</application>
</manifest>
