Question

当我的Android 23项目尝试通过HTTPS连接到我的服务器时，一切都很好。

如果我将目标SDK切换为24，则会出现以下错误：

切换回23并再次工作。
关于证书的最低要求，24有什么变化吗？

Answer 1

如果docker exec为24 +，则默认情况下，在Android 7.0上，用户安装的证书未通过“设置”应用合并：

默认情况下，来自所有应用的安全（例如TLS，HTTPS）连接信任预安装的系统CA，而针对API级别23（Android M）及以下的应用也默认信任用户添加的CA商店。

（来自the network security configuration docs）

要解决此问题，您需要定义network security configuration XML资源：

db

然后，从清单中targetSdkVersion元素中的<?xml version="1.0" encoding="utf-8"?> <network-security-config> <base-config> <trust-anchors> <certificates src="system"/> <certificates src="user"/> </trust-anchors> </base-config> </network-security-config>属性指向该XML资源。

通常，Android 7.0通过网络安全配置子系统（android:networkSecurityConfig和来自堆栈跟踪的亲属）路由HTTPS。这里引入的其他兼容性问题可能与<application>相关联。因此，如果缺少用户证书不是您的问题，您可以创建一个再现问题的示例项目file an issue。由于我保持a backport of that stuff，我有兴趣了解任何错误。： - ）

Android是否更改了API 24中的SSL配置？
