title: What is android:layout_marginStart
body: <p>I would like to add some space between the left display border and an ImageView. Android SDK made me aware of "android:layout_marginStart".</p>
  
  <blockquote>
    <p>Consider adding android:layout_marginStart="10dp" to better support right-to-left layouts</p>
  </blockquote>
  
  <p>Why should I use <code>android:layout_marginStart="10dp"</code> instead of <code>android:layout_marginLeft="10dp"</code>? I have never done so and never encountered any problems with so-called "right-to-left layouts".</p>
