问题
in my application I want that when a user click a button the application closes itself and automatically opens the add new widget context Menu. I'm making this:
if (viewId == R.id.bt_homeScreen) {
finish();
try {
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
startActivity(intent);
} catch (ActivityNotFoundException e) {
Toast.makeText(this.getApplicationContext(), getResources().getString(R.string.homeClientAlert), Toast.LENGTH_SHORT).show();
}
}
The problem whith this code is that I only go to the phone Home screen:

I want that when I launch the Intent it goes to the Home screen and open the widget context menu:

Take a look at Commonsware's answer to this question: Add widget to homescreen from Android application
You will be able to show the widget selection menu but you won't be able to process that selection in a normal app. The application that makes use of an appwidget selection must implement an AppWidgetHost. Home screen apps fall into this category, no normal apps.
