Can I install/add widgets during app installation or from within the app? (With User persmission, if possible)
Found an old, answered question. Is this still not possible in Nov'16?
Can I install/add widgets during app installation or from within the app?
As Android users know, there are many home screen implementations for Android. Across the thousands of device models there are hundreds of different pre-installed home screen implementations. And there are hundreds, if not thousands, of additional home screen implementations that the user can download and install from places like the Play Store.
None of these home screens have to support app widgets.
As such, Google did not implement an API to ask the home screen to install an app widget, let alone implement an API to force the home screen to install an app widget.
It is possible that some home screen implementations expose their own API for this, though I am not aware of any that do.
