This is the well formed tutorial about Android ninepatch, noted from "http://radleymarx.com/blog/simple-guide-to-9-patch/"  asically, 9-patch uses png transparency to do an advanced form of  9-slice  or  scale9 . The guides are straight, 1-pixel black lines drawn on the edge of your image that define the scaling and fill of your image. By naming your image file  name.9.png , Android will recognize the  9.png format and use the black guides to scale and fill your bitmaps. Here’s a basic guide map: As you can see, you have guides on each side of your image. The TOP and LEFT guides are for scaling your image (i.e. 9-slice), while the RIGHT and BOTTOM guides define the fill area.

Anything thicker than one pixel will remain part of your image. (My examples have 4-pixel wide guides for

If you normally call new activity as above, the activity of other app would be put in to same task of the current applications, which means you are not openning new application. You can see an example of opening mail client, the mail client allow you to call mail activity and it is put in to your curren
