After trying to mess around with soft input mode, the only thing that work for my requirement is setting android:windowSoftInputMode="adjustResize" of the activity in manifest and activity?.window?.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN) in specific fragment to allow me have a dynamic input mode between fragments.
Upon trying multiple setup I noticed that adjustResize programmatic approach WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE is deprecated but I don't see any deprecation warning when it is being used in the manifest nor in the Android documentation. This is also the default behavior I am getting when windowSoftInputMode is not specified. What is it that we are actually deprecating here? Is the two approach the same or not?
