1. You send the picture of your friend home and address and explain that you are staying with your firend. (Your friend house rental contract may be needed if your friend rent that house)
2. You book a paid booking for 2-3 days and send the hotel name and hotel address. (There may be some risk that the officer will check with the hotel for your stay). In case they ask you why only 2-3 days, you can tell them that you don't want to stay in one place for too long and you are visiting other places)
Other that that, I cannot think any other options.
