Image browse button in android activity


currently I'm developing an application which requires a browse button in my activity. When I press the browse button I should be able to browse the image files in my sdcard as well as in the phone memory. Upon tapping the image file it should be selected and the path of the image file (that is, where that selected image file is located) should be displayed in the activity in a textview. Also the selected image should be displayed in a imageview. How to do this? Can someone please help me out..
