Problem With Unity 3D and manifest

I have a problem uploading an app to Slideme.com

since when I upload I have this error

Your application must have a valid sdkVersion set. You need to edit your AndroidManifest.xml file to fix this, and then upload again the .apk file.

This is my Manifesto

<?xml version="1.0" encoding="utf-8"?>
<!--
This Google Mobile Ads plugin library manifest will get merged with your
application's manifest, adding the necessary activity and permissions
required for displaying ads.
-->
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.google.unity.ads"
    android:versionName="4.0"
    android:versionCode="7">
  <uses-sdk android:minSdkVersion="14"
      android:targetSdkVersion="14" />
  <application>
  </application>
</manifest>

Probe -1 vote against

Probe Deleting the Min version and placing the Target version as the minimum and as the version in which it is being compiled but nothing works

I appreciate that you can help me I have several days trying to find the solution
