ssl - Android TLS connection and self signed certificate

Question

I'm trying to connect to a node.js based TLS server from my Android app. Naturally it fails becouse I'm using a self-signed certificate.

Is there anyway I can just add the certificate to my app and have Android trust it somehow? Note, I'm not using HTTPS, this is a TLS over TCP connection.

After a lot of reading around, I came up with an answer.

A pretty good guide is here: http://nelenkov.blogspot.no/2011/12/using-custom-certificate-trust-store-on.html

Now, since I'm not using HTTPS, I had to come up with a slightly different approach for getting a clean SSL socket with the new keystore:

KeyStore store = KeyStore.getInstance("BKS");
InputStream truststore = mainActivity.getResources().openRawResource(R.raw.trust);
store.load(truststore, "PASSWORD".toCharArray());
TrustManagerFactory tmf = TrustManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
tmf.init(store);
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, tmf.getTrustManagers(), new SecureRandom());
Socket socket = context.getSocketFactory().createSocket(ip, port);
