            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

HttpURLConnection 使我的应用程序崩溃,因为即使我在清单文件中使用标签也没有授予互联网权限

It says no permissions requested

你能帮忙吗?

我正在使用 Marshmallow,我的 targetSdkVersion 是 23 我在 onCreate 方法中调用 HttpURLConnection

【问题讨论】:

你用棉花糖吗?你在哪里调用你的 httpurlconnection? "HttpURLConnection 使我的应用程序崩溃" -- 请编辑您的问题并发布 minimal reproducible example,包括崩溃的代码和崩溃的完整 Java 堆栈跟踪。 “它说没有请求权限”——列出了dangerous 权限;你的权限都没有protectionLevel 请问您的应用项目的目标编译版本是哪个Android版本? 是的,我使用 Marshmallow,targetSdkVersion 23 我在 onCreate 方法中调用 HttpURLConnection 【参考方案1】:

感谢@JoxTraex 解决了问题

您不能在主线程上执行任何网络调用。使用 AsyncTask 执行您的网络调用。
