I have made a custom keyboard using InputMethodService() and registered it in manifest file in android studio but issue is that it made the keyboard global means now when ever i am opening keyboard it open custom keyboard only, but my use case is that I want to get opened my custom keyboard on clicking certain edit text only and for remaining, inside my app want that default keyboard only. How can i achieve this.
