title: Intent Error at Android Studio (it makes app tiwce)
body: <p>My Android Studio installs my app twice.</p>
  <p>I guess I have some error at  <strong>AndroidManifest.xml</strong></p>
  <p>And I guess I think this error produces from <code>&lt;intent-filter&gt;</code>.Because I wrote it twice.</p>
  <p>I don't know how to fix the code.</p>
  <p>This is my code.</p>
  <pre><code>&lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
  </code></pre>
  <p></p>
  <pre><code>&lt;application
