I have been using Microsoft EWS in my Android application. The Android devices with versions < 4.4 received `Javax.net.ssl.SSLHandshakeException`, so I had to add the code below to solve the issue from this link . I tried other solutions related to these issues, but none other than these lines of codes worked.
ProviderInstaller.installIfNeeded(getApplicationContext());
SSLContext sslContext;
sslContext = SSLContext.getInstance("TLSv1.1");
sslContext.init(null, null, null);
sslContext.createSSLEngine();
After adding the code, the SSL issue was solved, but then came yet another big issue, the Microsoft EWS functions (login, create the event, etc..) keep crashing:
