Android studio 2.2 Cannot resolve symbol 'FragmentPagerAdapter'
<p>I have a project that is working perfectly on Android Studio 2.1 but when I updated to Android Studio 2.2 it stopped resolving <code>android.support.v13.app.FragmentPagerAdapter</code> I don't know why</p>

<p>I tried the project on Android Studio 2.1 again and it still working fine.
I tried to import settings from old to new Studio but this didn't solve it.
What's preventing Android Studio 2.2 from resolving <code>android.support.v13.app.FragmentPagerAdapter</code> ?</p>

<p>I have already tried :</p>

<pre><code>1、File-&gt;Invalidata Caches/Restart-&gt;Invalidata and Restart
2、Build-&gt;Make Module
3、Build-&gt;Make Project
4、Build-&gt;Clean Project
5、Build-&gt;Rebuild Project
</code></pre>

<p>I saw this question <a href="https://stackoverflow.com/questions/37336960/android-studio-2-2-1-cannot-resolve-symbol">android studio 2.2.1 cannot resolve symbol *</a> but I already have android studio 2.2 preview 2 and it didn't solve the issue.</p>

<p>This is my build.grade file for the app module :</p>
