It works for me   File imgFile   new  File   sdcard Images test image jpg    if imgFile exists         Bitmap myBitmap   BitmapFactory decodeFile imgFile getAbsolutePath           Drawable d   new BitmapDrawable getResources    myBitmap       ImageView myImage    ImageView  findViewById R id imageviewTest       myImage setImageBitmap myBitmap        Edit   If above hard-coded sdcard directory is not working in your case  you can fetch the sdcard path   String sdcardPath   Environment getExternalStorageDirectory   toString    File imgFile   new  File sdcardPath

Create bitmap from file path   File sd   Environment getExternalStorageDirectory    File image   new File sd filePath  imageName   BitmapFactory Options bmOptions   new BitmapFactory Options    Bitmap bitmap   BitmapFactory decodeFile image getAbsolutePath   bmOptions   bitmap   Bitmap createScaledBitmap bitmap parent getWidth   parent getHeight   true   imageView setImageBitmap bitmap     If you want to scale the bitmap to the parent s height and width then use Bitmap createScaledBitmap function   I think you are giving the wrong file path     Hope this helps

you can t access your drawables via a path  so if you want a human readable interface with your drawables that you can build programatically   declare a HashMap somewhere in your class   private static HashMap lt String  Integer gt  images   null     Then initialize it in your constructor   public myClass       if  images    null        images   new HashMap lt String  Integer gt         images put  Human1Arm   R drawable human one arm          for all your images - don t worry  this is really fast and will only happen once         Now for access -  String drawable    wrench      fill in this value however you want  but in the end you want Human1Arm etc    access is fast and easy  Bitmap wrench   BitmapFactory decodeResource getResources    images get drawable    canvas drawColor Color  BLACK   Log d  OLOLOLO  Integer toString wrench getHeight      canvas drawBitmap wrench  left  top  null

Well  using the static Drawable createFromPath String pathName  seems a bit more straightforward to me than decoding it yourself     -   If your mImg is a simple ImageView  you don t even need it  use mImg setImageUri Uri uri  directly
