Android 安卓应用程序在安卓8上运行，但在安卓6上崩溃

我正在构建一个应用程序，它在安卓8中运行良好

当我在旧版本上测试它时，我得到以下崩溃

• 安卓版本：6.0.1
• 设备：三星（SM-J500H）

有人能帮忙吗？

如果你使用自签名证书，谷歌不会接受。你应该使用X.509

当您请求服务器时，首先调用下面定义的

trustCerts

方法。然后，您可以启动一个请求

@SuppressLint("TrulyRandom")
public static void trustCerts() {
    try {
        TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {
            public X509Certificate[] getAcceptedIssuers() {
                return new X509Certificate[0];
            }

            @Override
            public void checkClientTrusted(X509Certificate[] certs, String authType) {
            }

            @Override
            public void checkServerTrusted(X509Certificate[] certs, String authType) {
            }
        }};

        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, trustAllCerts, new SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
        HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
            @Override
            public boolean verify(String arg0, SSLSession arg1) {
                return true;
            }
        });
    } catch (Exception e) {
        Log.e(TAG, "Could not trust certs:", e);
    }
}

您是否使用HTTPS进行请求？是的，我正在使用HTTPS。此错误原因是，您的url没有SSL证书。你有证书吗？是的，服务器有ssl证书，我使用的是matrix.org服务器，我们已经添加了它是配置ssl证书文件的路径，它在android 8上工作，但是现在当我在旧版本上测试时，我得到了这个错误，是sertifica自签名还是购买许可证？我应该在哪里调用这个方法示例，您想要解析json。您应该在先前请求时调用，请考虑通过将异常记录到某种形式的记录器来处理Tycatch语句，而不是对它做任何操作，除非您确实确信应该忽略catch语句。
