This:

logoImage = (ImageView) findViewById(R.drawable.logo);

…should probably be this:

logoImage = (ImageView) findViewById(R.id.logo);

…which also expects you to have an <ImageView /> in your layout XML with the id @+id/logo, similar to this:

<ImageView
    android:id="@+id/logo"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
/>

If your ImageView isn’t using the id @+id/logo, then just change the R.id.logo above to whatever you’ve picked. 🙂

TLDR: You’re trying to find a view based on the resource identifier of your Drawable. This is not the same as the identifier you’ve given your ImageView.
