title: Is app-release.apk zipaligned apk?
body: <p>I am using Android Studio 1.0.2. 
  When I click assembleRelease in gradle tasks, two files are generated, app-release-unaligned.apk and app-release.apk. I know app-release-unaligned.apk is unaligned but what is app-release.apk? Is it aligned apk? My build.gradle is like below.</p>
  
  <pre><code>buildTypes {
      release {
          minifyEnabled true
          proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
          signingConfig signingConfigs.config
          zipAlignEnabled true // Is this necessary or not in Android Studio 1.0.2?
      }
  }
  </code></pre>
  
  <p>Even if I didn't put zipAlignEnabled true, app-release.apk is generated.
  Is it still necessary in Android Studio 1.0.2?
  All information I get about zipalign is before Android Studio 1.0 comes out.</p>
