As of Android O, In your app, you can create a request for the system to pin a widget onto a supported launcher.

Create the widget in your app's manifest file Call the requestPinAddWidget() method

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
       AppWidgetManagermAppWidgetManager= getSystemService(AppWidgetManager.class);

        ComponentNamemyProvider=newComponentName(AddWidgetActivity.this, 
AppWidgetSmall.class);

        Bundleb=newBundle();
        b.putString("ggg", "ggg");
        if (mAppWidgetManager.isRequestPinAppWidgetSupported()) {
            IntentpinnedWidgetCallbackIntent=newIntent(AddWidgetActivity.this, 
 AppWidgetSmall.class);
            PendingIntentsuccessCallback= 
  PendingIntent.getBroadcast(AddWidgetActivity.this, 0,
                    pinnedWidgetCallbackIntent, 0);

            mAppWidgetManager.requestPinAppWidget(myProvider, b, successCallback);
        }
