Answer 1

This is how I handle it

ConnectionConfiguration config = new ConnectionConfiguration("your_server", port_no);
config.setSASLAuthenticationEnabled(true);
config.setCompressionEnabled(true);
config.setSecurityMode(SecurityMode.enabled);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
    config.setTruststoreType("AndroidCAStore");
    config.setTruststorePassword(null);
    config.setTruststorePath(null);
} else {
    config.setTruststoreType("BKS");
    String path = System.getProperty("javax.net.ssl.trustStore");
    if (path == null)
        path = System.getProperty("java.home") + File.separator + "etc"
            + File.separator + "security" + File.separator
            + "cacerts.bks";
    config.setTruststorePath(path);
}
