Share image and text through Whatsapp or Facebook

For sharing text and image on WhatsApp, more controlled version of code is below, you can add more methods for sharing with Twitter, Facebook ...

public class IntentShareHelper {

    public static void shareOnWhatsapp(AppCompatActivity appCompatActivity, String textBody, Uri fileUri) {
        Intent intent = new Intent(Intent.ACTION_SEND);
        intent.setType("text/plain");
        intent.setPackage("com.whatsapp");
        intent.putExtra(Intent.EXTRA_TEXT,!TextUtils.isEmpty(textBody) ? textBody : "");

        if (fileUri != null) {
            intent.putExtra(Intent.EXTRA_STREAM, fileUri);
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
            intent.setType("image/*");
        }

        try {
            appCompatActivity.startActivity(intent);
        } catch (android.content.ActivityNotFoundException ex) {
            ex.printStackTrace();
            showWarningDialog(appCompatActivity, appCompatActivity.getString(R.string.error_activity_not_found));
        }
    }

    public static void shareOnTwitter(AppCompatActivity appCompatActivity, String textBody, Uri fileUri){...}

    private static void showWarningDialog(Context context, String message) {
        new AlertDialog.Builder(context)
                .setMessage(message)
                .setNegativeButton(context.getString(R.string.close), new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.dismiss();
                    }
                })
                .setCancelable(true)
                .create().show();
    }
}

For getting Uri from File, use below class:

public class UtilityFile {
    public static @Nullable Uri getUriFromFile(Context context, @Nullable File file) {
        if (file == null)
            return null;

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            try {
                return FileProvider.getUriForFile(context, "com.my.package.fileprovider", file);
            } catch (Exception e) {
                e.printStackTrace();
                return null;
            }
        } else {
            return Uri.fromFile(file);
        }
    }

    // Returns the URI path to the Bitmap displayed in specified ImageView       
    public static Uri getLocalBitmapUri(Context context, ImageView imageView) {
        Drawable drawable = imageView.getDrawable();
        Bitmap bmp = null;
        if (drawable instanceof BitmapDrawable) {
            bmp = ((BitmapDrawable) imageView.getDrawable()).getBitmap();
        } else {
            return null;
        }
        // Store image to default external storage directory
        Uri bmpUri = null;
        try {
            // Use methods on Context to access package-specific directories on external storage.
            // This way, you don't need to request external read/write permission.
            File file = new File(context.getExternalFilesDir(Environment.DIRECTORY_PICTURES), "share_image_" + System.currentTimeMillis() + ".png");
            FileOutputStream out = new FileOutputStream(file);
            bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
            out.close();

            bmpUri = getUriFromFile(context, file);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return bmpUri;
    }    
}

Currently Whatsapp supports Image and Text sharing at the same time. (Nov 2014).

Here is an example of how to do this:

    /**
     * Show share dialog BOTH image and text
     */
    Uri imageUri = Uri.parse(pictureFile.getAbsolutePath());
    Intent shareIntent = new Intent();
    shareIntent.setAction(Intent.ACTION_SEND);
    //Target whatsapp:
    shareIntent.setPackage("com.whatsapp");
    //Add text and then Image URI
    shareIntent.putExtra(Intent.EXTRA_TEXT, picture_text);
    shareIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
    shareIntent.setType("image/jpeg");
    shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

    try {
        startActivity(shareIntent);
    } catch (android.content.ActivityNotFoundException ex) {
        ToastHelper.MakeShortText("Whatsapp have not been installed.");
    }

Please try the below code and hopefully it will work.

    Uri imgUri = Uri.parse(pictureFile.getAbsolutePath());
    Intent whatsappIntent = new Intent(Intent.ACTION_SEND);
    whatsappIntent.setType("text/plain");
    whatsappIntent.setPackage("com.whatsapp");
    whatsappIntent.putExtra(Intent.EXTRA_TEXT, "The text you wanted to share");
    whatsappIntent.putExtra(Intent.EXTRA_STREAM, imgUri);
    whatsappIntent.setType("image/jpeg");
    whatsappIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

    try {
        activity.startActivity(whatsappIntent);
    } catch (android.content.ActivityNotFoundException ex) {
        ToastHelper.MakeShortText("Whatsapp have not been installed.");
    }
