Read an Image/file from External storage Android

Question

I\'m trying to load an image from external storage. I set the permissions, I tried different ways, but none of them works.

BitmapFactory.Options options =          


        

Answer 1

File sdCard = Environment.getExternalStorageDirectory();

File directory = new File (sdCard.getAbsolutePath() + "/Pictures");

File file = new File(directory, "image_name.jpg"); //or any other format supported

FileInputStream streamIn = new FileInputStream(file);

Bitmap bitmap = BitmapFactory.decodeStream(streamIn); //This gets the image

streamIn.close();

Answer 2

Get the path of the image from your folder as below. And then decode the file as a bitmap.

   File file= new File(android.os.Environment.getExternalStorageDirectory(),"Your folder");
   Bitmap bitmap = BitmapFactory.decodeFile(file.getAbsolutePath())

Answer 3

There is a function called

createFromPath(String)

in the Drawable class. So the statement

String path="/storage/..<just type in the path>";
Drawable.createFromPath(path);

will return a drawable object

Answer 4

If i have file abc.jpg on the sdcard then:

String photoPath = Environment.getExternalStorageDirectory() + "/abc.jpg";

and to get bitmap.

BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
Bitmap bitmap = BitmapFactory.decodeFile(photoPath, options);

or

Bitmap bitmap1 = BitmapFactory.decodeFile(photoPath);

to avoide out of memory error I suggest you use the below code...

BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 8;
final Bitmap b = BitmapFactory.decodeFile(photoPath, options);

To avoid above issue you can use Picasso (A powerful image downloading and caching library for Android)

Documentation

How To?

Picasso.with(context).load("file:///android_asset/DvpvklR.png").into(imageView2);
Picasso.with(context).load(new File(...)).into(imageView3);

If you have a file path, just use BitmapFactory directly, but tell it to use a format that preserves alpha:

BitmapFactory.Options options = new BitmapFactory.Options();

options.inPreferredConfig = Bitmap.Config.ARGB_8888;

Bitmap bitmap = BitmapFactory.decodeFile(photoPath, options);
selected_photo.setImageBitmap(bitmap);
