*** ** * ** ***
Base class for derived classes to implement their `https://developer.android.com/reference/android/view/inputmethod/InputMethod`
interface. This takes care of basic maintenance of the input method,
but most behavior must be implemented in a derived class.
## Summary
### Inherited constants
From interface `https://developer.android.com/reference/android/view/inputmethod/InputMethod` `https://developer.android.com/reference/java/lang/String` `https://developer.android.com/reference/android/view/inputmethod/InputMethod#SERVICE_INTERFACE`
This is the interface name that a service implementing an input
method should say that it supports -- that is, this is the action it
uses for its intent filter.
`https://developer.android.com/reference/java/lang/String` `https://developer.android.com/reference/android/view/inputmethod/InputMethod#SERVICE_META_DATA`
Name under which an InputMethod service component publishes information
about itself.
`int` `https://developer.android.com/reference/android/view/inputmethod/InputMethod#SHOW_EXPLICIT`
*This constant was deprecated
in API level 37.
`https://developer.android.com/reference/android/view/inputmethod/InputMethodManager#SHOW_IMPLICIT` is deprecated therefore this flag
becomes the default. There is no need to pass it anymore.*
`int` `https://developer.android.com/reference/android/view/inputmethod/InputMethod#SHOW_FORCED`
*This constant was deprecated
in API level 35.
Starting in `https://developer.android.com/reference/android/os/Build.VERSION_CODES#BAKLAVA`,
`https://developer.android.com/reference/android/view/inputmethod/InputMethodManager#SHOW_IMPLICIT` is deprecated and has no effect, therefore all
requests will have this flag set. IMEs should no longer react to this flag.*
