Android - Share on Facebook, Twitter, Mail, ecc

Paresh Mayani's answer is mostly correct. Simply use a Broadcast Intent to let the system and all the other apps choose in what way the content is going to be shared.

To share text use the following code:

String message = "Text I want to share.";Intent share = new Intent(Intent.ACTION_SEND);share.setType("text/plain");share.putExtra(Intent.EXTRA_TEXT, message);startActivity(Intent.createChooser(share, "Title of the dialog the system will open"));

yes you can ... you just need to know the exact package name of the application:

• Facebook - "com.facebook.katana"
• Twitter - "com.twitter.android"
• Instagram - "com.instagram.android"
• Pinterest - "com.pinterest"

And you can create the intent like this

Intent intent = context.getPackageManager().getLaunchIntentForPackage(application);if (intent != null) {     // The application exists     Intent shareIntent = new Intent();     shareIntent.setAction(Intent.ACTION_SEND);     shareIntent.setPackage(application);     shareIntent.putExtra(android.content.Intent.EXTRA_TITLE, title);     shareIntent.putExtra(Intent.EXTRA_TEXT, description);     // Start the specific social application     context.startActivity(shareIntent);} else {    // The application does not exist    // Open GooglePlay or use the default system picker}

I think you want to give Share button, clicking on which the suitable media/website option should be there to share with it. In Android, you need to create createChooser for the same.

Sharing Text:

Intent sharingIntent = new Intent(Intent.ACTION_SEND);sharingIntent.setType("text/plain");sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "This is the text that will be shared.");startActivity(Intent.createChooser(sharingIntent,"Share using"));

Sharing binary objects (Images, videos etc.)

Intent sharingIntent = new Intent(Intent.ACTION_SEND);Uri screenshotUri = Uri.parse(path);sharingIntent.setType("image/png");sharingIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);startActivity(Intent.createChooser(sharingIntent, "Share image using"));
