I read the documentation, but I did not understand what is the purpose of the DETAILS_META_DATA constant of the android.speech.RecognizerIntent class.
I read the source code of this class (in particular the getVoiceDetailsIntent method) and I have seen that the DETAILS_META_DATA constant is used to obtain the class name of the speech recognizer.
Is only this the purpose of this constant?
I can see no practical purpose for the constant in normal use of
RecognizerIntent.Perhaps, if you someone’s device has a second speech recognizer installed, your app could use
DETAILS_META_DATAto determine which one they are using.
