SetImageBitmap Not Working in Android

I'm developing an app for Android, I'm using the Gallery widget, and I've resized it to fullscreen mode, so it displays one image at a time.

<com.example.librosapp.MyGallery 
        android:id="@+id/examplegallery" android:layout_width="1920px"
        android:layout_height="1020px"
        android:padding="0px"
        android:layout_marginTop="-20px"
        />

And here is a part of my Activity's code:

public View getView(int position, View convertView, ViewGroup parent) {
        ImageView imgView = new ImageView(cont);

        //Here are my changes:
        File imgFile = new  File("sdcard/Libreria/0/0/0.JPG");
        if(imgFile.exists()){
            Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
            //The app runs OK til here:
            imgView.setImageBitmap(myBitmap);
            //BOOM! Exception
        }           

        imgView.setLayoutParams(new MyGallery.LayoutParams(1950, 1000));
        imgView.setScaleType(ImageView.ScaleType.FIT_XY);


        return imgView;
    }

I don't know which exception am I getting, because I can't debug here, I'm using the .APK in my device. (The only way that I have to debug this, is with the virtual device, and I donnow why it runs really slow.

Am I doing something wrong?, that code works perfect if I use the same image, but as a project Resource (using setImageDrawable)

This is happening because myBitMap is null. myBitMap is null because the file path is invalid. My guess would be the file path should be /sdcard/Libreria/0/0/0.JPG
