android jack server问题总结

这里以我的解决方法为例
1.确定自己安装的编译系统
   Linux test-Z490-UD 4.15.0-142-generic #146~16.04.1-Ubuntu SMP Tue Apr 13 09:27:15 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
2.java 版本
   test@test-Z490-UD:~$ java -version
   openjdk version "1.8.0_292"
   OpenJDK Runtime Environment (build 1.8.0_292-8u292-b10-0ubuntu1~16.04.1-b10)
   OpenJDK 64-Bit Server VM (build 25.292-b10, mixed mode)
   test@test-Z490-UD:~$ javac -version
   javac 1.8.0_292
   test@test-Z490-UD:~$
3. curl -v https://127.0.0.1:8076 这个包与连接要能执行，有错的话，我这边不影响，可以跳过做其它试验，回头来看这个问题

/
test@test-desktop:~$ curl -v https://127.0.0.1:8076

curl: (60) SSL certificate problem: self signed certificate
More details here: https://curl.haxx.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.
test@test-desktop:~$

4.配置文件的权限确定
没有这个文件 ~/.jack-server/config.properties
先编译一次android源码，或者修改一下 ~/.jack-settings 的端口，记录下来，先编译一下，我这边就生成了
有这个文件，就可以修改端口了，没有这个文件，就不能修改，这个文件要编译自己生成的

5.tty只有一个人登录使用，不要多个tty登录去测试，如果一个tty登录编译能正确，那么就是多个用户端口的问题
这里的多个用户，一是指ubuntu下，或者linux下的不同用户，二是不同人的tty登录情况，个人总结与理解
所有，如果其它用户能编译能过，则自己在任何用户，任何tty的情况，包括ssh putty登录，都要重新统一配置jack-server的端口，并且
对jack-server停止，再启动 jack-admin restart-server

5.jack-server的加密与连接问题
尝试：
#找到这段
jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES, MD5withRSA, \
DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \
include jdk.disabled.namedCurves

#删掉其中的TLSv1, TLSv1.1 , 改成下面这样即可
jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, \
DH keySize < 1024, EC keySize < 224, anon, NULL, \
include jdk.disabled.namedCurves

6.关闭所有的tty登录
分别使用root用户与普通用户进行登录
或者对android的源码进行 7777 权限处理再编译
7.java方面的的修改，我没有使用过
添加java运行参数-Xmx4g
还有一种方法是说修改prebuilts/sdk/tools/jack-admin脚本，修改java运行参数，添加-Xmx4g，其中4g是指内存大小，以自己编译机的实际内存的一半为宜。
修改方法如下：

-JACK_SERVER_VM_ARGUMENTS="${JACK_SERVER_VM_ARGUMENTS:=-Dfile.encoding=UTF-8 -XX:+TieredCompilation}"
+JACK_SERVER_VM_ARGUMENTS="${JACK_SERVER_VM_ARGUMENTS:=-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4g }"

-JACK_SERVER_COMMAND="java -XX:MaxJavaStackTraceDepth=-1 -Djava.io.tmpdir=$TMPDIR $JACK_SERVER_VM_ARGUMENTS -cp $LAUNCHER_JAR $LAUNCHER_NAME"
+JACK_SERVER_COMMAND="java -XX:MaxJavaStackTraceDepth=-1 -Djava.io.tmpdir=$TMPDIR $JACK_SERVER_VM_ARGUMENTS -Xmx4g -cp $LAUNCHER_JAR $LAUNCHER_NAME"

8.jacks-server curl 是否支持https方式或者其它的方式查资料学习确定
