React-native : Compiling Android error on processReleaseResources step
<p>I m trying to compiling my app for android with react-native 0.25 ( i know that s not the last one but i started the project a long time ago now ) .</p>

<p>I recently changed one of my assets from "downArrow.jpg" to "downArrow.png" .
From this time, i can t compile for release mode because i m facing the following issue with gradle :</p>

<pre><code>18:04:27.715 [INFO] [org.gradle.api.Project] Unknown source file : res\drawable-mdpi-v4\assets_downarrow.png:0: error: Resource entry assets_downarrow is already defined.
18:04:27.726 [INFO] [org.gradle.api.Project] Unknown source file : res\drawable-mdpi-v4\assets_downarrow.jpg:0: Originally defined here.
</code></pre>

<p>since i have no folder "drawable-mdpi-v4" in the android resources folder i guess react native push my assets into this folder but the problem is i only have the "downArrow.png" left, the jpg one has already delete from the git.</p>

<p>I restarted the react-native packager and also ran the following command : 
    cd Android &amp;&amp; ./gradlew clean build assemble </p>

<p>but the problem still remain.</p>

<p>any idea ? </p>
