Now I could open an external App of dictionary in my app. My code is as following
====================================
B4X:
Sub OpenDictionary(keyword As String )
Dim PackageName As String, I As Intent, p As PackageManager
PackageName=modFun.GetTheApp("oxfordadvanceddiction")
I = p.GetApplicationIntent(PackageName)
StartActivity(I)
End Sub
but everytime I have to type the vocabulary that I want to look up. I wonder that if I can pass the vocabulary to the App of dictionary when my app call this external app in my App. Highly appreciate for any kind of support.
