不起作用javax.net.ssl.SSLHandshakeException:握手失败
Not work javax.net.ssl.SSLHandshakeException: Handshake failed
我尝试了许多方法，许多代码，但仍然没有
I tried many methods, many codes, and still haven't
推荐答案
当android从TLSv1退回到SSLv3时，通常会发生该错误.
That error usually occurs when android falls back to SSLv3 from TLSv1.
尝试以下解决方案:
打开您的 Application 类，并在其 onCreate() 方法中编写以下代码.
Open your Application class and write below code in its onCreate() method.
try {
ProviderInstaller.installIfNeeded(getApplicationContext());
SSLContext sslContext;
sslContext = SSLContext.getInstance("TLSv1.2");
sslContext.init(null, null, null);
sslContext.createSSLEngine();
} catch (GooglePlayServicesRepairableException | GooglePlayServicesNotAvailableException
| NoSuchAlgorithmException | KeyManagementException e) {
e.printStackTrace();
}
