Android Studio HTTPS和SSL证书

Question

currently, i'm in the midst of developing mobile apps for Android using Android Studio.

so far, login/senddata/getdata/viewdata in my mobile apps work like a charm in my local PC and HTTP web . i use HttpUrlConnection in my coding

the problem is how to make my mobile apps run/send data/retrieve data/communicate with PHPMySQL in my HTTPS server.

its only working on HTTP web server. HTTPS does not work at all and my mobile apps is crashed and stop working.

i have test my mobile apps into both HTTP & HTTPS server (SSL & Self-signed certificate)

is there any addition on the coding that i need to be aware of to make it accessible into HTTPS ?

Thanks.

Answer 1

The official Android documentation for HTTPS has details about how HTTPS connections work in Android, including commonly seen errors.

If you have a trusted certificate that was issued by a CA or a reseller, your current code with HttpURLConnection should work fine. From https://developer.android.com/reference/java/net/HttpURLConnection.html ,

Calling openConnection() on a URL with the "https" scheme will return an HttpsURLConnection , which allows for overriding the default HostnameVerifier and SSLSocketFactory . An application-supplied SSLSocketFactory created from an SSLContext can provide a custom X509TrustManager for verifying certificate chains and a custom X509KeyManager for supplying client certificates.

If you're using self signed certificates (not recommended in Production), this article at CodeProject describes the process to handle this.
