title: Android: Proper coding of getCacheDir()
body: <p>I am researching on how to get the cache file size and directory of every application that is installed in my android phone programmatically, based on what I found on my research, I need to use <strong>getCacheDir()</strong>, my question is, what is the proper coding using <strong>getCacheDir()</strong> ?
  can someone give me an example how to use it? I'm new to android so I'm not familiar yet on the proper coding in android</p>
