我一直在挣扎几个小时。我一直在试图从我的android应用程序发出一个请求。我发现我不能只从主线程发出请求，所以我发现我可以将它放在可运行的线程中。我尝试了很多人使用的方法，为别人工作，并且没有人为我工作。我有点明白了一个为这一个（不为我工作）：我允许它获得的存取权限互联网这样发送android的帖子请求

服务器端脚本API作品，我只是在一个网络应用程序中使用它。
有人可以指出我正确的方向吗？我无能为力。哪里可能是错误？也许错误在我的gradle中（我必须从apache.com下载http库并包含在我的gradle中 - 必须添加一个依赖编译org.apache.httpcomponents：httpclient：4.5'和一堆packagingOptions {
exclude 'META-INF/DEPENDENCIES'
exclude 'META-INF/NOTICE'
exclude 'META-INF/LICENSE'
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/NOTICE.txt'
}）有没有简单的方法？也发现了关于okhttp库，我将尝试实现它，但我真的不擅长使用gradle和导入外部库。
这就是我得到：
