Android - Share on Facebook, Twitter, Mail, ecc

I need to develop an app that has the share function. I have to share on Facebook, twitter, email and maybe other services.

How can I do this? There a library on the net? For the iOS development there were ShareKit, but for Android?

Thanks :)

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"));

FYI, above code are referred from Sharing content in Android using ACTION_SEND Intent

Use this

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



SharingToSocialMedia("com.facebook.katana")


public void SharingToSocialMedia(String application) {

	Intent intent = new Intent();
	intent.setAction(Intent.ACTION_SEND);
	intent.setType("image/*");
	intent.putExtra(Intent.EXTRA_STREAM, bmpUri);

	boolean installed = checkAppInstall(application);
	if (installed) {
		intent.setPackage(application);
		startActivity(intent);
	} else {
		Toast.makeText(getApplicationContext(),
				"Installed application first", Toast.LENGTH_LONG).show();
	}

}


 private boolean checkAppInstall(String uri) {
    PackageManager pm = getPackageManager();
    try {
        pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
        return true;
    } catch (PackageManager.NameNotFoundException e) {
    }

    return false;
}

The ACTION_SEND will work correctly for all and it takes the Body of the text to wall in twitter, G mail.. but it fails For Face Book page... Its as known bug in the Facebook android SDK .. but still they haven't fixed it

This will help

1- First Define This Constants

 public static final String FACEBOOK_PACKAGE_NAME = "com.facebook.katana";
    public static final String TWITTER_PACKAGE_NAME = "com.twitter.android";
    public static final String INSTAGRAM_PACKAGE_NAME = "com.instagram.android";
    public static final String PINTEREST_PACKAGE_NAME = "com.pinterest";
    public static final String WHATS_PACKAGE_NAME =  "com.whatsapp";

2- Second Use This method

 public static void shareAppWithSocial(Context context, String application, String title, 
 String description) {

        Intent intent = new Intent();
        intent.setAction(Intent.ACTION_SEND);
        intent.setPackage(application);

        intent.putExtra(android.content.Intent.EXTRA_TITLE, title);
        intent.putExtra(Intent.EXTRA_TEXT, description);
        intent.setType("text/plain");

        try {
            // Start the specific social application
            context.startActivity(intent);
        } catch (android.content.ActivityNotFoundException ex) {
            // The application does not exist
            Toast.makeText(context, "app have not been installed.", Toast.LENGTH_SHORT).show();
        }


    }

I think the following code will help....

public void btnShareClick(View v) {
	// shareBtnFlag = 1;
	Dialog d = new Dialog(DrawAppActivity.this);
	d.requestWindowFeature(d.getWindow().FEATURE_NO_TITLE);
	d.setCancelable(true);

	d.setContentView(R.layout.sharing);

	final Button btnFacebook = (Button) d.findViewById(R.id.btnFacebook);
	final Button btnEmail = (Button) d.findViewById(R.id.btnEmail);

	btnEmail.setOnClickListener(new OnClickListener() {

		public void onClick(View arg0) {
			if (!btnEmail.isSelected()) {
				btnEmail.setSelected(true);

				eTask.execute();

				List<ResolveInfo> list = getPackageManager()
						.queryIntentActivities(sendIntent,
								PackageManager.MATCH_DEFAULT_ONLY);

				if (list.size() != 0) {

					startActivity(Intent.createChooser(sendIntent,
							"Send Email Using:"));

				}

				else {
					AlertDialog.Builder confirm = new AlertDialog.Builder(
							DrawAppActivity.this);
					confirm.setTitle(R.string.app_name);
					confirm.setMessage("No Email Sending App Available");
					confirm.setPositiveButton("Set Account",
							new DialogInterface.OnClickListener() {
								public void onClick(DialogInterface dialog,
										int which) {
									dialog.dismiss();
								}
							});
					confirm.show();
				}
			} else {
				AlertDialog.Builder confirm = new AlertDialog.Builder(
						DrawAppActivity.this);
				confirm.setTitle(R.string.app_name);
				confirm.setMessage("No Email Account Available!");
				confirm.setPositiveButton("Set Account",
						new DialogInterface.OnClickListener() {

								Intent i = new Intent(
										Settings.ACTION_SYNC_SETTINGS);
								startActivity(i);
								dialog.dismiss();
							}
						});
				confirm.setNegativeButton("Cancel",
						new DialogInterface.OnClickListener() {
							public void onClick(DialogInterface dialog,
									int which) {

								dialog.dismiss();
							}
						});
				confirm.show();
			}
		}

	});

	btnFacebook.setOnClickListener(new OnClickListener() {

		public void onClick(View arg0) {
			if (!btnFacebook.isSelected()) {
				btnFacebook.setSelected(true);
			} else {
				btnFacebook.setSelected(false);
			}
			saveBtnFlag = 1;

	d.show();

For facebook application use facebook SDK

The ACTION_SEND will only give you options for sending using GMail, YahooMail... etc(Any application installed on your phone, that can perform ACTION_SEND). If you want to share on Facebook or Twitter you will need to place custom buttons for each and use their own SDK such as Facebook SDK or Twitter4J .

> Create Choose Editable

Intent sendIntent = new Intent(Intent.ACTION_SEND);
        	sendIntent.setType("text/plain");
        	sendIntent.putExtra(Intent.EXTRA_SUBJECT, "My application name");
        	String sAux = "\nLet me recommend you this application\n\n";
        	sAux = sAux + "https://play.google.com/store/apps/details?id=the.package.id \n\n";
        	sendIntent.putExtra(Intent.EXTRA_TEXT, sAux);
        	startActivity(Intent.createChooser(sendIntent, "choose one"));

==============================================================

> Create Choose Default

        	Intent sendIntent = new Intent(Intent.ACTION_SEND);
        	sendIntent.setType("text/plain");
        	sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
        	startActivity(sendIntent);

=================================================================

> Multi-Piece send

Send multiple pieces of content

To share multiple pieces of content, use the ACTION_SEND_MULTIPLE action together with a list of URIs pointing to the content. The MIME type varies according to the mix of content you're sharing. For example, if you share 3 JPEG images, the type is still "image/jpeg". For a mixture of image types, it should be "image/*" to match an activity that handles any type of image. You should only use "*/*" if you're sharing out a wide variety of types. As previously stated, it's up to the receiving application to parse and process your data. Here's an example:

ArrayList<Uri> imageUris = new ArrayList<Uri>();
imageUris.add(imageUri1); // Add your image URIs here
imageUris.add(imageUri2);

Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND_MULTIPLE);
shareIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, imageUris);
shareIntent.setType("image/*");
startActivity(Intent.createChooser(shareIntent, "Share images to.."));

================================================================

> Share With Facebook

    ShareLinkContent shareLinkContent = new ShareLinkContent.Builder()
            .setQuote("Application of social rating share with your friend")
            .setContentUrl(Uri.parse("https://google.com"))
            .build();
    if (ShareDialog.canShow(ShareLinkContent.class)) {
        sd.show(shareLinkContent);
    }

==============================================================

> Share With SMS

    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_VIEW);
    intent.putExtra("Body", "Application of social rating share with your friend");
    intent.setType("vnd.android-dir/mms-sms");
    startActivity(intent);

==============================================================

> Share With Mail

    Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto", "", null));
    emailIntent.putExtra(Intent.EXTRA_EMAIL, "Address");
    emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Application of social rating share with your friend");
    emailIntent.putExtra(Intent.EXTRA_TEXT, "Body");
    startActivity(Intent.createChooser(emailIntent, "Send Email..."));

=============================================================

> Share with WhatsApp

    Intent whatsappIntent = new Intent(Intent.ACTION_SEND);
    whatsappIntent.setType("text/plain");
    whatsappIntent.setPackage("com.whatsapp");
    whatsappIntent.putExtra(Intent.EXTRA_TEXT, "Application of social rating share with your friend");
    try {
        Objects.requireNonNull(getActivity()).startActivity(whatsappIntent);
    } catch (android.content.ActivityNotFoundException ex) {
        Toast.makeText(getActivity(), "WhatsApp have not been installed.", Toast.LENGTH_SHORT).show();
    }

This will let you share your app on whats app etc:

try
			{ Intent i = new Intent(Intent.ACTION_SEND);  
			  i.setType("text/plain");
			  i.putExtra(Intent.EXTRA_SUBJECT, "My application name");
			  String sAux = "\nLet me recommend you this application\n\n";
			  sAux = sAux + "https://play.google.com/store/apps/details?id=Orion.Soft \n\n";
			  i.putExtra(Intent.EXTRA_TEXT, sAux);  
			  startActivity(Intent.createChooser(i, "choose one"));

String message = "This is testing."
Intent shareText = new Intent(Intent.ACTION_SEND);
shareText .setType("text/plain");
shareText .putExtra(Intent.EXTRA_TEXT, message);

startActivity(Intent.createChooser(shareText , "Title of the dialog the system will open"));

sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"your subject" );
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "your text");
startActivity(Intent.createChooser(sharingIntent, ""));

Share on Facebook
