SetImageURi(uri) problems

[murali.lancer]

hi friends ,
I am facing problem that whenever i am setting the image to a ImageView dynamically from a file path(not from the Res,drawable),by using SetImageURI(uri),i am getting one error like

resolve uri failed on bad bitmap uri

so how can i get the image from a file path by using this setImageURI(uri)

Thanks and Regards
