You can also use         File imgFile   new  File    filepath          if imgFile exists                  ImageView myImage   new ImageView this           myImage setImageURI Uri fromFile imgFile              This does the bitmap decoding implicit for you

Labeeb is right about why you need to set image using path if your resources are already laying inside the resource folder    This kind of path is needed only when your images are stored in SD-Card    And try the below code to set Bitmap images from a file stored inside a SD-Card    File imgFile   new  File   sdcard Images test image jpg     if imgFile exists          Bitmap myBitmap   BitmapFactory decodeFile imgFile getAbsolutePath          ImageView myImage    ImageView  findViewById R id imageviewTest        myImage setImageBitmap myBitmap        And include this permission in the manifest file    lt uses-permission android name  android permission WRITE EXTERNAL STORAGE    gt

Most of the answers are working but no one mentioned that the high resolution image will slow down the app   In my case i used images RecyclerView which was taking 0 9 GB of device memory In Just 30 Images   I Choreographer  Skipped 73 frames   The application may be doing too much work on its main thread   The solution is Sipmle you can degrade the quality like here   Reduce resolution of Bitmap But I use Simple way   Glide handles the rest of work fanContext  let               Glide with it                   load Uri fromFile File item filePath                     into viewHolder imagePreview
