Question

How can I access an image that has the path “DCIM/Camera/test.jpg” ? (DCIM is in the top level directory when I open the Android device in Android File Transfer. )

Answer 1

Now that we know you’re trying to load it into an ImageView:

ImageView imageView = (ImageView) findViewById(R.id.yourImageView);
Bitmap bMap = BitmapFactory.decodeFile("/sdcard/DCIM/Camera/" + yourFileName);
imageView.setImageBitmap(bMap);

And as Aerrow mentioned, you need to make sure you have the proper permissions in your manifest:

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