Android : java.io.FileNotFoundException when trying to copy a image from Photos app

I'm trying to get a image from android Photos app using the share option that point to my PhotoGetFromGallery activity. Here is the code:

public void copy(File src, File dst) throws IOException {
    FileInputStream inStream = new FileInputStream(src);
    FileOutputStream outStream = new FileOutputStream(dst);
    FileChannel inChannel = inStream.getChannel();
    FileChannel outChannel = outStream.getChannel();
    inChannel.transferTo(0, inChannel.size(), outChannel);
    inStream.close();
    outStream.close();
}

public boolean isExternalStorageWritable() {
    String state = Environment.getExternalStorageState();
    if (Environment.MEDIA_MOUNTED.equals(state)) {
        return true;
    }
    return false;
}

void handleSendImage(Intent intent) {
    Uri imageUri = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);
    String sourcePath = getRealPathFromURI(imageUri);
    if(isExternalStorageWritable()) {
        if (imageUri != null) {
            File sd = Environment.getExternalStorageDirectory();
            File data = Environment.getDataDirectory();
            String destinationImagePath = sd + "/Pictures/MyAppImgFolder/";
            File source = new File(data, sourcePath);
            String fileName = source.getName();
            File destination = new File(sd, destinationImagePath + fileName);
            try {
                copy(source, destination);
            } catch (Exception e) {
                Log.e("COPY IMAGE ERROR", e.toString() + ". Destination Path is " + destinationImagePath.toString() + " and Source path is "+ sourcePath);
            }
        }
    }
}

sourcePath string returns the correct image path (ex. /storage/emulated/0/Pictures/Instagram/IMG_20150413_114608.jpg). However, I'm getting the FileNotFoundException because Environment.getDataDirectory() returns /data/storage/emulated/0/Pictures/Instagram/IMG_20150413_114608.jpg.

Here is my log:

E/COPY IMAGE ERROR﹕ java.io.FileNotFoundException: /data/storage/emulated/0/Pictures/Instagram/IMG_20150413_114608.jpg: open failed: ENOENT (No such file or directory). Destination Path is /storage/emulated/0/Pictures/MyAppImgFolder/ and Source path is /storage/emulated/0/Pictures/Instagram/IMG_20150413_114608.jpg

Here is my AndroidManifest.xml:

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

My question is how can I get, if possible, any path of images stored at Photos app or Android Gallery?
