I want to implement something like this. 
 
It should not be hard coded. If user haven't installed Dropbox there should not be a option to share via Dropbox.
Thanks in advance !

You can do the same by using:
Intent i=new Intent(android.content.Intent.ACTION_SEND);
i.setType("text/plain");
i.putExtra(android.content.Intent.EXTRA_SUBJECT,"Subject test");
i.putExtra(android.content.Intent.EXTRA_TEXT, "extra text that you want to put");
startActivity(Intent.createChooser(i,"Share via"));
Detailed example is here for your reference: http://mobile.tutsplus.com/tutorials/android/android-sdk-implement-a-share-intent/
For Sharing the Content Via:
Intent shareIntent =  new Intent(android.content.Intent.ACTION_SEND); 
//set type  
shareIntent.setType("text/plain");  
//add what a subject you want
shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"add what a subject you want");  
 String shareMessage="message body"; 
//message  
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT,shareMessage); 
//start sharing via 
startActivity(Intent.createChooser(shareIntent,"Sharing via"));  
in KOTLIN :
startActivity(createShareIntent(url))
fun createShareIntent(url: String): Intent = Intent.createChooser(Intent().apply {
    action = Intent.ACTION_SEND
    putExtra(Intent.EXTRA_TEXT, url)
    type = "text/plain"
}, null)
Hope it will helpful.
