title: Android Studio HTTPS and SSL Certificate
body: <p>currently, i'm in the midst of developing mobile apps for Android using Android Studio. </p>
  
  <p>so far, login/senddata/getdata/viewdata in my mobile apps work like a charm in my local PC and <strong>HTTP web</strong>. i use <strong><em>HttpUrlConnection</em></strong> in my coding</p>
  
  <p>the problem is how to make my mobile apps run/send data/retrieve data/communicate with PHPMySQL in my <strong>HTTPS</strong> server. </p>
  
  <p>its only working on HTTP web server. 
  HTTPS does not work at all and my mobile apps is crashed and stop working.</p>
  
  <p>i have test my mobile apps into both <strong>HTTP &amp; HTTPS server (SSL &amp; Self-signed certificate)</strong></p>
  
  <p>is there any addition on the coding that i need to be aware of to make it accessible into HTTPS ? </p>
  
  <p>Thanks.</p>
