Add <com.blogspot.android_er.androidgif.GifView> in layout file, layout/activity_main.xml

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="10dp"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:autoLink="web"
        android:text="http://android-er.blogspot.com/"
        android:textStyle="bold" />

    <com.blogspot.android_er.androidgif.GifView
        android:id="@+id/gifview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal" />

</LinearLayout>

Nothing to do in com.blogspot.android_er.androidgif.MainActivity.java

package com.blogspot.android_er.androidgif;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    GifView gifView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        gifView = (GifView)findViewById(R.id.gifview);
    }

}

Edit src/main/AndroidManifest.xml to add <uses-permission> of "android.permission.INTERNET", and disable hardware ccceleration by setting android:hardwareAccelerated="false".

<?xml version="1.0" encoding="utf-8"?>
