title: Manifest Merger Error - Different versions of support library
body: <p>I'm adding the stepper indicator library - <a href="https://github.com/badoualy/stepper-indicator" rel="noreferrer">https://github.com/badoualy/stepper-indicator</a> - to my project. To do so, I added jitpack to my project gradle file and the stepper-indicator library to my app gradle file. However, I'm getting the following build error:</p>
  
  <pre><code>Error:Execution failed for task ':app:processDebugManifest'.
  &gt; Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(25.4.0) from [com.android.support:preference-v14:25.4.0] AndroidManifest.xml:25:13-35
      is also present at [com.android.support:appcompat-v7:26.0.0-beta2] AndroidManifest.xml:28:13-41 value=(26.0.0-beta2).
      Suggestion: add 'tools:replace="android:value"' to &lt;meta-data&gt; element at AndroidManifest.xml:23:9-25:38 to override.
  </code></pre>
  
  <p>The other dependencies in my app include:</p>
  
  <pre><code>compile 'com.android.support:preference-v7:25.4.0'
  compile 'com.android.support:preference-v14:25.4.0'
  compile 'eu.davidea:flexible-adapter:5.0.0-rc2'

  compile 'com.squareup.okhttp3:okhttp:3.8.1'
  </code></pre>
  
  <p>Without upgrading all of the android support libraries to an alpha version, is there a solution to this problem?</p>
