Getting started photoshop design for an Android application

Question

I am designing an android application in photoshop. But I am stuck at the first step itself. I have so many confusion and after searching for a solution in google confusion increased threefold.

My big confusions are

1.What should be the canvas size
2.What is the size of status bar
3.How many sizes of assets i have to handover to development team.

Few suggested me to do everything in DP. Again confusion.

1.How to setup photoshop workspace in DP.
2.What is the size of the canvas I have to start with.
3.What is the size of status bar.
4.how to set text size in sp.

Thank you so much.

Answer 1

Consider dp = px in Photoshop

1. xlarge screens are at least 960dp x 720dp
2. large screens are at least 640dp x 480dp
3. normal screens are at least 470dp x 320dp
4. small screens are at least 426dp x 320dp

Following more specific

1. 320dp: a typical phone screen (240x320 ldpi, 320x480 mdpi, 480x800 hdpi, etc).
2. 480dp: a tweener tablet like the Streak (480x800 mdpi).
3. 600dp: a 7” tablet (600x1024 mdpi).
4. 720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc).
