How to know whether android shortcut already exist

Question

while creating shortcut I get toast like "Shortcut created" and subsequently "Shortcut already exists".I have set the intent for duplicate and it doesnt create any duplicate. Now my doubt is

How can i detect if the shortcut already exist.
how can I disable the toast messages like "Shortcut created" and "Shortcut already exists".I have checked the LauncherModel(under com.android) api that shows the Toast,but app like WhatsApp dont show any Toast.

When creating shortcut you can add like this

addIntent.putExtra("duplicate", true);

(then when creating, create duplicate shortcut even it exist )

ex.

public void createShortcut(String url,,String classname,String shortcutName , String type)
    {           
        Intent shortcutIntent = new Intent();       
        shortcutIntent.setAction(Intent.ACTION_VIEW);

        if(type.equalsIgnoreCase("web")) {  

            Uri uri = Uri.parse(url);
            shortcutIntent.setData(uri);
        }
        else if (type.equalsIgnoreCase("app")) {


            shortcutIntent.setClassName(url,classname);
        }

        shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

        Intent addIntent = new Intent();
        addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
        addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, shortcutName);
        addIntent.putExtra("duplicate", true);

       addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, R.drawable.ic_launcher);

        addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
        sendBroadcast(addIntent);
//        Toast mToast = Toast.makeText(this, "shortcut created", Toast.LENGTH_SHORT);
//        mToast.show();

    }

This doesn't help. If the shortcut already exists, you get a toast saying "Shortcut already exists". — David Wasser, Nov 19 '12 at 17:10

You must use uniqie ID for your shortcuts (For example shortcut name or id from server db)

In begging of your add shortcut method:

if (loadBoolean(context, String.valueOf(shortcutid))) return;

After sendbroadcast method you must call:

saveBoolean(context, true, String.valueOf(shortcutid));

Code of save and load methods:

 protected static boolean saveBoolean(Context context, boolean value, String tag) {
        try {
           PreferenceManager.getDefaultSharedPreferences(context).edit().putBoolean(tag, value).apply();
        } catch (Exception e) {
            return false;
        }
        return true;
    }

    protected static boolean loadBoolean(Context context, String tag) {
        boolean value = false;
        try {
            value = PreferenceManager.getDefaultSharedPreferences(context).getBoolean(tag, false);
        } catch (Exception ignored) {}
        return value;
    }

I also have the same problem like u, I've deleted the shortcut n wanted to create it again, but it keeps coming out with the message "Shortcut xxx already exist".

I tried changing the contact name and it works.
