Android: I created a bitmap from canvas and save it to “sdcard/folder/subfolder” but I couldn't decode it to a image view

Question

I've created a bitmap from canvas. Save it to my "/sdcard/folder/subfolder/file.png"

I want to get this png file into imageview after saving it. I tried this by using BitmapFactory.decodeFile("/sdcard/folder/subfolder/file.png"); method. But it returned nothing. There is no image on imageview.

Do you have any idea?
