I use ksoap2 to access a webservice. Everything was just fine before to change the test webservice with production one, witch use a https protocol.
I know that this question was asked few more times here, on stackoverflow, but none of the answers work for me. When I use ksoap2 with https I got this error (exception):
Not trusted server certificate
Someone provided and answer (solution) here: Android ksoap2 via https but I don't understand how to implement that solution (or the proposed solution is not working for me)
The certificate used by WS is a self issued ssl certificate - I use the application only inside a small company, but the company system administrator requires encrypted connection.
Can someone provide a better explanation for this issue?
Thank you.
I had a similar problem. Basically, when using Http related classes with the https protocol, Android will check with its installed certificates(which I believe are stored in the os keystore).
Because your certificate is self-signed, the certificate is not trusted. I added my self-signed certificate to my app for testing purposes(alexander.egger's answer at How to install trusted CA certificate on Android device?). Maybe you can use this approach? I guess Vedran's approach at Android ksoap2 via https does a similar thing and should work too. What part of that answer is unclear?
However, I dont think these are good solutions.
For my production environment, I ordered a (cheap) ssl certificate from a signing authority trusted by all Android devices and installed it on the server. I am not going to advertise here, but most commercial ssl certificates are trusted by all android devices, and it should be easy to find a cheap one with some research. I think this is the best solution to this problem. Without a proper ssl certificate, your server would be untrusted to the entire world except your particular app, which is probably not a good solution(what if you extend to an ios device, a third party application calling the webservice,etc..).
