今天用android studio在模拟器上运行程序总是出错，模拟器能起来，但程序一直安装运行不了，查看错误日志发现如下错误：
10:49 Emulator: [5228:9620:0808/104900.536:ERROR:ssl_client_socket_impl.cc(1050)] handshake failed; returned -1, SSL error code 1, net_error -10310:49 Emulator: [5228:9620:0808/104900.613:ERROR:ssl_client_socket_impl.cc(1050)] handshake failed; returned -1, SSL error code 1, net_error -10310:49 Emulator: [5228:9620:0808/104919.819:ERROR:ssl_client_socket_impl.cc(1050)] handshake failed; returned -1, SSL error code 1, net_error -10310:49 Emulator: emulator: INFO: QtLogger.cpp:68: Critical: Uncaught ReferenceError: $ is not defined (qrc:/html/js/location-loader.js:1, (null))10:49 Emulator: [5228:9620:0808/104919.824:ERROR:ssl_client_socket_impl.cc(1050)] handshake failed; returned -1, SSL error code 1, net_error -10310:49 Emulator: emulator: INFO: QtLogger.cpp:68: Critical: Uncaught ReferenceError: $ is not defined (qrc:/html/js/location-loader.js:1, (null))
如图：
根据网上的方法试了很多，比如重启模拟器，配置变量等方法都未成功，最后看了一个帖子，问题得以解决，解决方法如下：
进入SDK中的platform-tools文件夹下打开cmd，我这里的路径为：E:\software\rj\bianji\Android\SDK\platform-tools，进入后输入cmd后按回车
即打开cmd窗口：
重启adb，输入如下命令：
adb kill-server
adb devices
