title: Android Studio gradle failed to resolve for SDK version 16
body: <p>I just installed Android Studio for a new class and I can't even run a HelloWorld program. There are no third party dependencies as I literally just installed Android Studio, SDK version 16, the latest support repository, latest build tools, and created a Nexus 5 AVD running 4.1.2 (16). I keep getting </p>
  
  <pre><code>"Error:(24,13) Failed to resolve: com.android.support.appcompat-v7:16.+"
  </code></pre>
  
  <p>Here is my <code>build.gradle</code>:</p>
  
  <pre><code>apply plugin: 'com.android.application'
  
  android {
  compileSdkVersion 16
  buildToolsVersion '23.0.2'
  
  defaultConfig {
      applicationId "edu.usna.mobileos.hellooooworld"
      minSdkVersion 16
      targetSdkVersion 16
      versionCode 1
      versionName "1.0"
  }
  buildTypes {
      release {
          minifyEnabled false
          proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
      }
  }
  }
  
  dependencies {
      compile fileTree(dir: 'libs', include: ['*.jar'])
      testCompile 'junit:junit:4.12'
      compile 'com.android.support:appcompat-v7:16.+' // line giving me the error
  }
  </code></pre>
  
  <p>I've tried many other solutions I've found online, but none have worked so far. I need to work with API version 16 (Android 4.1.2) in this class, so using a newer API isn't an option.</p>
