SSL on Android <3.0

Issue

I would like to parse JSON which is secured with SSL (https), and on Android 2.x I obtain: "No Peer Certificate Exception", and I don't know (almost) anything about certificates, can somebody explain how to step by step how to integrate SSL certificate to my app and use it (which I understand I had to). Thats my current code:

HttpGet httppost =  new HttpGet(url);
httppost.setHeader("Content-type", "application/json");
response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
inputStream = entity.getContent();

Solution

The exception means that the device does not trust the certificate of your server. If the used server certificate is a paid one (bought by a trustcenter) this means that the trustcenter certificate is not present on that device.

You can add the trustcenter certificate (or a self-signed certificate) into your app by placing it into a BouncyCastle Keystore (BKS)

Note that the latest versions of BouncyCastle produce by default a BKS file of a newer version that can not be read by Android. You need BouncyCastle 1.46.
