Android Question How to insert an image thumbnail into mediastore?

[Inman]

Previously I asked a question on how to delete thumbnails from mediastore and got a working solution from Erel using ContentResolver. Now I am trying to do the opposite i.e. insert an image thumbnail into mediastore.

I can see that ContentResolver has an Insert method but the parameters confuse me. The second parameter is Values As android.content.ContentValues. Not sure how to build this because I have just the directory path and filename of the image file, whose thumbnail needs to be inserted to mediastore.

Based on the java code I found here, it looks like values will include MIME_Type and DATE_TAKEN. Please help me with translating to B4A code.

   Dim values As ContentValues
   Dim uri1 As Uri
   uri1.Parse("content://com.android.contacts/raw_contacts") ' adapt. this is from an example
   values.Initialize
   values.PutNull("account_name")
   values.PutNull("account_type")
   Dim rawUri As Uri = cr.Insert(uri1, values)

Thanks Don. I guess Images.Media.MIME_TYPE in Java becomes mimetype in B4A. Now what about Images.Media.DATE_TAKEN and MediaStore.MediaColumns.DATA?

no idea. Check googles Mediastore documentation.
