Answer 1

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);
            } else {
                btnEmail.setSelected(false);
            }
            saveBtnFlag = 1;
            // Check if email id is available-------------
            AccountManager manager = AccountManager
                    .get(DrawAppActivity.this);
            Account[] accounts = manager.getAccountsByType("com.google");
            Account account = CommonFunctions.getAccount(manager);
            if (account.name != null) {
                emailSendingTask eTask = new emailSendingTask();

Share on Facebook

private ShareDialog shareDialog;

shareDialog = new ShareDialog((AppCompatActivity) context);
shareDialog.registerCallback(callbackManager, new FacebookCallback<Sharer.Result>() {
    @Override
    public void onSuccess(Sharer.Result result) {
        Log.e("TAG","Facebook Share Success");
        logoutFacebook();
    }

    @Override
    public void onCancel() {
        Log.e("TAG","Facebook Sharing Cancelled by User");
    }

    @Override
    public void onError(FacebookException error) {
        Log.e("TAG","Facebook Share Success: Error: " + error.getLocalizedMessage());
    }
});

if (ShareDialog.canShow(ShareLinkContent.class)) {
    ShareLinkContent linkContent = new ShareLinkContent.Builder()
            .setQuote("Content goes here")
            .setContentUrl(Uri.parse("URL goes here"))
            .build();
    shareDialog.show(linkContent);
}

AndroidManifest.xml

<!-- Facebook Share -->
<provider
    android:name="com.facebook.FacebookContentProvider"
    android:authorities="com.facebook.app.FacebookContentProvider{@string/facebook_app_id}"
    android:exported="true" />

dependencies {
    implementation 'com.facebook.android:facebook-share:[5,6)' //Facebook Share
}

Share on Twitter

public void shareProductOnTwitter() {
    TwitterConfig config = new TwitterConfig.Builder(this)
            .logger(new DefaultLogger(Log.DEBUG))
            .twitterAuthConfig(new TwitterAuthConfig(getResources().getString(R.string.twitter_api_key), getResources().getString(R.string.twitter_api_secret)))
            .debug(true)
            .build();
    Twitter.initialize(config);

    twitterAuthClient = new TwitterAuthClient();

    TwitterSession twitterSession = TwitterCore.getInstance().getSessionManager().getActiveSession();

    if (twitterSession == null) {
        twitterAuthClient.authorize(this, new Callback<TwitterSession>() {
            @Override
            public void success(Result<TwitterSession> result) {
                TwitterSession twitterSession = result.data;
                shareOnTwitter();
            }

            @Override

            }
        });
    } else {
        shareOnTwitter();
    }
}

private void shareOnTwitter() {
    StatusesService statusesService = TwitterCore.getInstance().getApiClient().getStatusesService();
    Call<Tweet> tweetCall = statusesService.update("Content goes here", null, false, null, null, null, false, false, null);
    tweetCall.enqueue(new Callback<Tweet>() {

            Log.e("TAG","Twitter Share Failed with Error: " + exception.getLocalizedMessage());
        }
    });
}

Answer 3

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
}

Answer 4

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

Answer 5

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

Answer 6

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();
        }


    }
