val EXTRA_CALLING_PACKAGE_INTEROP: String = "android.support.v4.app.EXTRA_CALLING_PACKAGE"(source)

Intent extra that stores the name of the calling package for an ACTION_SEND intent. When an activity is started using startActivityForResult this is redundant info. (It is also provided by getCallingPackage.) Note that this is only for interoperability between pre-1.0 AndroidX and AndroidX 1.1+ worlds. You are strongly encouraged to use getCallingPackage or getCallingPackage.
