  <pre><code>Gradle: Execution failed for task ':Project:processDebugManifest'.
  &gt; Manifest merging failed. See console for more info.
  </code></pre>
  
  <p>In <code>AndroidManifest.xml</code></p>
  
  <pre><code>&lt;uses-sdk
      android:minSdkVersion="16"
      android:targetSdkVersion="18" /&gt;
  </code></pre>
  
  <p>In <code>build.gradle</code></p>
  
  <pre><code>android {
      compileSdkVersion 18
      buildToolsVersion "18.1.1"
  
      defaultConfig {
          minSdkVersion 16
          targetSdkVersion 18
