title: How to create a Mini Map in Android Google Maps API v2?
body: <p>I want to use a kind of "mini map" over my GoogleMap. The minimum requisites are create markers and change zoom dynamically (of both). Is there an easier way than create two GoogleMaps with two fragments? </p>
  
  <p>I think using two GoogleMaps at the same time decreases the performance, I didn't try it yet.</p>
  
  <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

      android:layout_width="match_parent"
      android:layout_height="match_parent" &gt;
  
  
      &lt;fragment
          android:id="@+id/miniMap"
          android:name="com.example.presentation.views.MainActivity"
          android:layout_width="300dp"
          android:layout_height="300dp"
          class="com.google.android.gms.maps.MapFragment" /&gt;
      &lt;fragment
          android:id="@+id/bigMap"
          android:name="com.example.presentation.views.MainActivity"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          class="com.google.android.gms.maps.MapFragment" /&gt;
  
  
  &lt;/RelativeLayout&gt;
