Voglio memorizzare l'immagine nel database sqlite che viene presa dalla galleria e fotocamera android

Question

Ho un'applicazione in cui l'utente aggiunge un'immagine facendo clic su Imageview e impostando l'immagine e scattando nuova foto dalla fotocamera. Voglio memorizzare quell'immagine nel database sqlite.

**AddkeyEventdetail.java**

database.java

pubblico insertAddKeyEvent vuoto (byte [] childpic, String EventDate, eventDetails String)

{ 
    ContentValues addkeyValues=new ContentValues(); 
    addkeyValues.put("CHILDPICS",childpic); 
    addkeyValues.put("EVENTDATE", eventDate); 
    addkeyValues.put("EVENTDETAILS", eventDetails); 

    parentmaster.insert("ADDKEYEVENT",null,addkeyValues); 



}

Convertire tua Bitmap in un byte[] dal seguente senso

ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
bitmap.compress(CompressFormat.JPEG, 100, baos); 
byte[] imageData = baos.toByteArray(); 

e aggiungere byte[] in un campo BLOB nel database.
