Android R.anim.files cannot be found
<p>I am not sure if it is only me but strangely, I cannot access slide_in_right.xml and slide_out_left.xml inside res/anim that I created
<br><br> I am using this line of code to access the animation </p>

<pre><code>UserProfile.this.overridePendingTransition(android.R.anim.slide_in_right, android.R.anim.slide_out_left);
</code></pre>

<p>However, it underlines the slide_in_right and slide_out_left saying that it cannot Resolve symbol.</p>

<p>Methods tried:<br>
1. Clean the project<br>
   &nbsp;&nbsp;&nbsp;&nbsp;Still cannot Resolve symbol for both android.R.anim.slide_in_right and <br>&nbsp;&nbsp;&nbsp;&nbsp;android.R.anim.slide_out_left<br><br>
2. Rebuild project <br>
   &nbsp;&nbsp;&nbsp;&nbsp;Gives me an error saying <b>error: cannot find symbol variable slide_in_right</b> <br><br>
3. Double checked if i spelled the anim uncorrectly but it seem to be correct</p>
