Install Home Screen Widgets Progrommaticly

I have main activity window in my app, which displays three icons on it, also there are 3 home screen widgets in this application. is there a possibility for long press on one of

Solution 1:

The user will have to manually install the app widget. Since widgets need to be positioned -- and so users do not have app widgets forced upon them -- users must choose to add it to their home screen.

Solution 2:

In Android O, its possible to set app widget programmatically.

AppWidgetManagermAppWidgetManager=
    context.getSystemService(AppWidgetManager.class);

AppWidgetProviderInfomyWidgetProviderInfo=newAppWidgetProviderInfo();
ComponentNamemyProvider= myWidgetProviderInfo.provider;

if (mAppWidgetManager.isRequestPinAppWidgetSupported()) {
  // Create the PendingIntent object only if your app needs to be notified// that the user allowed the widget to be pinned. Note that, if the pinning// operation fails, your app isn't notified.IntentpinnedWidgetCallbackIntent=newIntent( ... );

  // Configure the intent so that your app's broadcast receiver gets// the callback successfully. This callback receives the ID of the// newly-pinned widget (EXTRA_APPWIDGET_ID).PendingIntentsuccessCallback= PendingIntent.createBroadcast(context, 0,
          pinnedWidgetCallbackIntent);

  mAppWidgetManager.requestPinAppWidget(myProvider, null,
           successCallback.getIntentSender());
}
