Android N java.security.cert.CertPathValidatorException：未找到證書路徑的信任錨

Question

在我的應用程序中，我使用自簽名證書通過https進行連接。該應用程序的工作時compilesdk設置爲< 24完全正常，但是當compilesdk爲24我的應用程序無法通過https連接到服務器，並拋出以下異常：

我也跟着提到的步驟這裏https://developer.android.com/preview/features/security-config.html，但是我的應用仍然無法通過https連接到服務器。我network_security_config.xml是如下：

<?xml version="1.0" encoding="utf-8"?> 
<network-security-config> 
    <domain-config> 
     <domain includeSubdomains="true">test.abc.com</domain> 
     <trust-anchors> 
      <certificates src="@raw/ca_norton"/> 
     </trust-anchors> 
    </domain-config> 
</network-security-config> 

在我AndroidManifest.xml中包含的應用程序標記

<meta-data android:name="android.security.net.config" 
      android:resource="@xml/network_security_config" /> 

ca_norton.crt也被複制到原始文件夾下的下面。我在這裏錯過了什麼嗎？提前致謝。

在您的清單指定網絡安全配置正確的方法是：

<?xml version="1.0" encoding="utf-8"?> 
<manifest ... > 
    <application android:networkSecurityConfig="@xml/network_security_config" 
      ... > 
    ... 
    </application> 
</manifest>
