title: Glide-4.0.0 Missing placeholder, error, GlideApp and does not resolve its method placeholder,error
body: <p>I want to use the Glide Android library to download an image and show in <code>ImageView</code>.</p>
  
  <p>In the previous version we used:</p>
  
  <pre><code>Glide.with(mContext).load(imgUrl)
                  .thumbnail(0.5f)
                  .placeholder(R.drawable.PLACEHOLDER_IMAGE_NAME)
                  .error(R.drawable.ERROR_IMAGE_NAME)
                  .crossFade()
                  .diskCacheStrategy(DiskCacheStrategy.ALL)
                  .into(imageView);
  </code></pre>
  
  <p>But I have seen Glide documentation:</p>
  
  <blockquote>
    <p>it says use <code>GlideApp.with()</code> instead <code>Glide.with()</code></p>
  </blockquote>
  
  <p>My concern is a missing placeholder, error, GlideApp, and other options.</p>
  
  <p>I am using</p>
  
  <pre><code> compile 'com.github.bumptech.glide:glide:4.0.0'
  </code></pre>
  
  <p>Where am I doing wrong? With reference to <a href="http://bumptech.github.io/glide/doc/getting-started.html" rel="noreferrer">here</a>.</p>
  
  <p>How has <code>GlideApp.with()</code> been used?</p>
  
  <p>The API is generated in the same package as the <code>AppGlideModule</code> and is named <code>GlideApp</code> by default. Applications can use the API by starting all loads with <code>GlideApp.with()</code> instead of <code>Glide.with()</code>:</p>
  
  <pre><code>GlideApp.with(fragment)
     .load(myUrl)
     .placeholder(placeholder)
     .fitCenter()
     .into(imageView);
  </code></pre>
