title: Can't find react-native package in external libraries
body: <p>We have two modules named app and lib. Since we have to add rn into lib, we have added lib's build.gradle with :</p>
  
  <pre><code>dependencies {
  compile fileTree(include: ['*.jar'], dir: 'libs')
  compile "com.facebook.react:react-native:+"  // From node_modules}
  </code></pre>
  
  <p>and in project's build.gradle</p>
  
  <pre><code>allprojects {
  repositories {
      mavenLocal()
      jcenter()
      maven {
          // All of React Native (JS, Android binaries) is installed from npm
          url "$rootDir/../node_modules/react-native/android"
      }
  }}
  </code></pre>
  
  <p>and node_modules has been downloaded and put in the usual folder,with package.json</p>
  
  <pre><code>"dependencies": {
  "react": "15.1.0",
  "react-native": "0.28.0" }
  </code></pre>
  
  <p>and
  <code>G:\dev&gt;react-native -v
  react-native-cli: 1.0.0
  react-native: 0.28.0</code></p>
  
  <p>We event have </p>
  
  <pre><code>&lt;orderEntry type="library" exported="" name="react-native-0.28.0" level="project" /&gt;
  </code></pre>
  
  <p>in the <code>lib.iml</code>, and can find react-native 0.28's dependencies like <code>okhttp-3.2.0</code> and <code>okio-1.8.0</code>(never used or added before) in studio's External Libraries, </p>
  
  <p>But <code>react-native-0.28.0</code> never appears in studio's External Libraries and not valid for the code.</p>
  
  <p>Any ideas why that happen? Thanks in advance.</p>
  
  <p><strong>update</strong></p>
  
  <p>After I put <code>compile 'com.android.support:appcompat-v7:23.1.1'</code> in app module's dependency <code>react-native-0.28.0</code> appears... that's very strange, Is that a bug or something?</p>
