How to display external storage image in imageview

Question

I want to display external storage image like:

"storage/sdcard0/image.jpg"

in my android application.

can any one guide me how to achieve this?

Answer 1

If your image is in the root folder of sdcard then access it through

 Bitmap bmp = BitmapFactory.decodeFile(Environment.getExternalStorageDirectory().toString + File.separator + "yourimage.jpg");     
 webImage.setImageBitmap(bmp);

Answer 2

this is the right way to do this:

Bitmap myBitmap = BitmapFactory.decodeFile(Environment.getExternalStorageDirectory() + File.separator + "image.jpg");     
myImageView.setImageBitmap(myBitmap);

but is necessary add the permission:

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

or require this permission manually for OS 6.0+ :

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M){

 int permissionCheck = ContextCompat.checkSelfPermission(
            this, Manifest.permission.WRITE_EXTERNAL_STORAGE);
    if (permissionCheck != PackageManager.PERMISSION_GRANTED) {      
            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 225);
    } 

}

Answer 3

Try this function:

Bitmap bitmap = BitmapFactory.decodeFile(Environment.getExternalStorageDirectory()+File.separator+"image.png");

Set this bitmap to imageview:

imageView.setImageBitmap(bitmap);
