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:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
All the answers are outdated. It is best to use picasso for such purposes. It has a lot of features including background image processing.
Did I mention it is super easy to use:
Picasso.with(context).load(new File(...)).into(imageView);
String path = Environment.getExternalStorageDirectory()+ "/Images/test.jpg";
File imgFile = new File(path);
if(imgFile.exists())
{
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
ImageView imageView=(ImageView)findViewById(R.id.imageView);
imageView.setImageBitmap(myBitmap);
}
From the official site: http://developer.android.com/training/displaying-bitmaps/load-bitmap.html
ImageView image = (ImageView) findViewById(R.id.imagePreview);
try {
image.setImageBitmap(decodeSampledBitmap(picFilename));
} catch (Exception e) {
e.printStackTrace();
}
Here the methods:
private int calculateInSampleSize(
BitmapFactory.Options options, int reqWidth, int reqHeight) {
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
final int halfHeight = height / 2;
final int halfWidth = width / 2;
// Calculate the largest inSampleSize value that is a power of 2 and keeps both
// height and width larger than the requested height and width.
while ((halfHeight / inSampleSize) > reqHeight
&& (halfWidth / inSampleSize) > reqWidth) {
inSampleSize *= 2;
}
}
return inSampleSize;
}
private Bitmap decodeSampledBitmap(String pathName,
int reqWidth, int reqHeight) {
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(pathName, options);
// Calculate inSampleSize
options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
return BitmapFactory.decodeFile(pathName, options);
}
//I added this to have a good approximation of the screen size:
private Bitmap decodeSampledBitmap(String pathName) {
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
return decodeSampledBitmap(pathName, width, height);
}

if you are using image loading in List view then use Aquery concept .
https://github.com/AshishPsaini/AqueryExample
AQuery aq= new AQuery((Activity) activity, convertView);
//load image from file, down sample to target width of 250 pixels .gi
File file=new File("//pic/path/here/aaaa.jpg");
if(aq!=null)
aq.id(holder.pic_imageview).image(file, 250);
onLoadImage Full load
private void onLoadImage(final String imagePath) {
ImageSize targetSize = new ImageSize(imageView.getWidth(), imageView.getHeight()); // result Bitmap will be fit to this size
//ImageLoader imageLoader = ImageLoader.getInstance(); // Get singleto
com.nostra13.universalimageloader.core.ImageLoader imageLoader = com.nostra13.universalimageloader.core.ImageLoader.getInstance();
imageLoader.init(ImageLoaderConfiguration.createDefault(getContext()));
imageLoader.loadImage(imagePath, targetSize, new SimpleImageLoadingListener() {

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)
}
