Android: Display Image from SD CARD

Question

This is driving me insane! Here\'s my code (I know this file exists):

File imageFile = new File(\"/sdcard/gallery_photo_4.jpg\");
ImageView jpgView = (Image         


        

Answer 1

This code worked for me finally:

    setContentView(R.layout.main);
    ImageView jpgView = (ImageView)findViewById(R.id.imageView);
    Bitmap bitmap = BitmapFactory.decodeFile("/sdcard/sample-1.jpg");
    jpgView.setImageBitmap(bitmap);

Crash was happening because setContentView() was not performed before attaching the jpgview:

code that was crashing:

    ImageView jpgView = (ImageView)findViewById(R.id.imageView);
    Bitmap bitmap = BitmapFactory.decodeFile("/sdcard/sample-1.jpg");
    jpgView.setImageBitmap(bitmap);
    setContentView(R.layout.main);

Answer 2

I would rather use a BitmapFactory to decode the Image from the file-path:

Bitmap bitmap = BitmapFactory.decodeFile(imageFile.getAbsolutePath());
jpgView.setImageBitmap(bitmap);

The Docs say:

If the specified file name is null, or cannot be decoded into a bitmap, the function returns null.

Can you check if the code works with another image and if you can open your image on your PC thought. Maybe the file is corrupt.

Answer 3

String imagePath = Environment.getExternalStorageDirectory().toString() + PATH_TO_IMAGE;
return Drawable.createFromPath(imagePath)

Answer 4

USE THIS LINE OF CODE FOR GETTING IMAGE FROM SDCARD. AND THEN DISPLAY IT IN YOUR IMAGEVIEW

where "FileInputOutput" is a folder in your sdcard

    String path = Environment.getExternalStorageDirectory()+ "/FileInputOutput/img1.jpg"; 
            File imgFile = new File(path);
            if(imgFile.exists())
        {
                Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());                  
                ImageView myImage = (ImageView) findViewById(R.id.imageView1);
                myImage.setImageBitmap(myBitmap);
        }
            else                    
                Toast.makeText(v.getContext(),"no IMAGE IS PRESENT'",Toast.LENGTH_SHORT).show();
        }
