How to implement share via option in android?

问题

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"));

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"));
