Create app shortcut inside the Custom Launcher in Android

I'm trying to develop a custom launcher that will contain the shortcut of my installed application (or even apk files). I can create a shortcut BUT outside the application and what I need to do is to create it inside my launcher activity. How can I do that?

AdminActivity.java (This activity contains a method that has the ability to create shortcut of the installed app from the device)

private boolean installUninstall_ShortCut(Context context, String appName, boolean isTrue) {
    boolean flag =false ;
    int app_id=-1;
    PackageManager pm = context.getPackageManager();
    Intent i = new Intent(Intent.ACTION_MAIN);
    i.addCategory(Intent.CATEGORY_LAUNCHER);
    List<ResolveInfo> res = pm.queryIntentActivities( i,0);


    for(int k=0; k<res.size(); k++) {
        if(res.get(k).activityInfo.loadLabel(pm).toString().equals(appName)){
            flag = true;
            app_id = k;

            break;
        }
    }

    if(flag) {
        ActivityInfo ai = res.get(app_id).activityInfo;

        Intent shortcutIntent = new Intent(Intent.ACTION_MAIN);
        shortcutIntent.setClassName(ai.packageName, ai.name);
        shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

        Intent intent = new Intent();
        intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
        intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, appName);
        intent.putExtra("duplicate", false);

        if(isTrue) {        
            intent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, Intent.ShortcutIconResource.fromContext(context, R.drawable.ic_launcher));
            intent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");       
        } else {
            intent.setAction("com.android.launcher.action.UNINSTALL_SHORTCUT");
        }

        context.sendBroadcast(intent);

    } else
        System.out.println("applicaton not found");
    return true;
}

activity_launcher.xml (This is the Layout of Launcher Activity where the shortcut will go. I really don't know how to bring the created shortcut in this activity)

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/plain_without_logo"
    tools:context=".S_2nd_MainActivity" >

<GridView
    android:id="@+id/grid_app"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:columnWidth="80dp"
    android:gravity="center"
    android:horizontalSpacing="15dp"
    android:numColumns="auto_fit"
    android:padding="10dp"
    android:stretchMode="columnWidth"
    android:verticalSpacing="15dp" />

What you are creating is not a launcher like the home screen, its just an application. The launcher category refers to the activity being listed in the all apps drawer. I don't think applications can add their own shortcuts otherwise spam ware could just keep adding its icon to your home screen like this and annoy every user.

Also installUninstall_ShortCut is not how we name things in Java! Actually it doesn't match any naming convention I've ever come across

If you want to mimic adding-shortcut-like functionality then you can get the grid view and call addView on it
