title: Android Studio - No resource found that matches the given name
body: <p>I am developing an app in Android Studio, I used the Android Asset Studio to make the launcher icon, and then I tried to Copy/Paste the new icon to overwrite the default one (like I always did in Eclipse) and nothing happens, so what I did was changing the name of the default ic_launcher to <code>a.png</code> and then from the windows eplorer copy/paste each <code>ic_launcher.png</code> in the corresponding mipmap folder, and delete de <code>a.png</code>'s files (while Android Studio was running) and then that error was shown.</p>
  <p>I tried clean, rebuild, build , refresh, resync the project and nothing happens, I am getting the same error. I also try to rename the build folder to build.old as <a href="https://stackoverflow.com/questions/17893372/error-building-project-in-android-studio-error-no-resource-found-that-matches">this</a> thread says, but still the error.</p>
  <pre><code>Error:(16, 23) No resource found that matches the given name (at 'icon' with value '@mipmap/a.png').
  Error:Execution failed for task ':app:processDebugResources'.
  &gt; com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Users\MyUser\AppData\Local\Android\Sdk\build-tools\21.1.2\aapt.exe'' finished with non-zero exit value 1
  </code></pre>
  <p><strong>Manifest.xml</strong></p>
  <pre><code> ...&lt;application
          android:allowBackup=&quot;true&quot;
          android:icon=&quot;@mipmap/a.png&quot;
          android:label=&quot;@string/app_name&quot;
          android:theme=&quot;@style/AppTheme&quot; &gt;
          &lt;activity ...
  </code></pre>
  <p>Also I tried to change the value of <code>android:icon=&quot;@mipmap/a.png&quot;</code> to <code>android:icon=&quot;@mipmap/ic_launcher.png&quot;</code> but every time I rebuild it changes again to <code>a.png</code>.</p>
  <p>Would I have to start from 0 and make a new project and copy all the things I have done or there is a way to fix this?</p>
