在 LINUX/android 目录下执行如下命令，发现：OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to localhost:8077 仍然是ssl错误，意思是client给服务端发送了TLSv1.3加密方式的hello握手请求，直接就报错了。

❯ JACK_EXTRA_CURL_OPTIONS=-v ./prebuilts/sdk/tools/jack-admin list server

也可通过如下命令得出错误log。

./prebuilts/sdk/tools/jack-admin dump-report

可能会看到如下的错误，意思是没有合适的协议，协议被禁用或密码套件不对称。

javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)

解决如下，解除jdk中的ssl3禁用算法，去掉SSLv3，这样便支持了TLSv1.3，再编译即可。

nano /usr/lib/jvm/java-1.8.0-openjdk-amd64/jre/lib/security/java.security //jdk路径
//或代码中的jdk文件：LINUX/android/prebuilts/jdk/jdk8/linux-x86/jre/lib/security/java.security

    EC keySize < 224 
jdk.tls.disabledAlgorithms=TLSv1,TLSv1.1, RC4, MD5withRSA, DH keySize < 768, \
EC keySize < 224 //去掉SSLv3修改后
