title: AndroidAnnotations Nothing Generated, Empty Activity
body: <p>I am trying to create a project using AndroidAnnotations in Android Studio. When I build and run the project, everything seems to compile fine, yet I get nothing but a blank activity for the app. In addition, it does not appear that anything is generated by AndroidAnnotations. </p>
  
  <p>I have added <code>androidannotations-api-2.7.1.jar</code> as a dependency for my project, and enabled annotation processing with the processor path the path to <code>androidannotations-2.7.1.jar</code>, which is in a separate folder from <code>androidannotations-api-2.7.1.jar</code>. I have checked store generated sources relative to module content root, and tried many different directories for the sources -- from <code>generated</code>, to <code>gen/aa</code>, to (currently) <code>build/source/aa</code> to match where it seems the generated files are created in Android Studio. Nothing has worked. I have changed the activity name in the manifest to <code>Activity_</code>, and set the configuration to launch this when the project is run. </p>
  
  <p>The only other dependencies I have are android-support-v4 and ActionBarSherlock. I have tried with both of these disabled, to no result. I initially planned to use Roboguice in conjunction with AndroidAnnotations, but have disabled it for the time being to try to focus on this issue. </p>
  
  <p>I am also using, or trying to use, Gradle. This is currently my <code>build.gradle</code>: </p>
  
  <pre><code>buildscript {
    repositories {
      maven { url 'http://repo1.maven.org/maven2' }
    }
    dependencies {
      classpath 'com.android.tools.build:gradle:0.4'
    }
  }
  
  apply plugin: 'android'
  
  dependencies {
    compile files('libs/android-support-v4.jar')
    compile files('libs/actionbarsherlock-4.3.1.jar')
    compile files('libs/androidannotations-api-2.7.1.jar')
  }
  
  android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"
  
    defaultConfig {
      minSdkVersion 7
      targetSdkVersion 17
    }
  }
  </code></pre>
  
  <p>However, I haven't really figured out how Gradle works, so I mostly just manually added the dependencies as you would a normal project, then put the compile lines in Gradle so the project would compile properly. I know this is probably not the correct way to use it.</p>
  
  <p>My activity and its layout are fairly standard, I just copied them from the official guide to get started with AndroidAnnotations.</p>
  
  <p>UPDATE: So I just went back to Maven to test the build with that, and I noticed something strange. It seems that even with how I have it set up in Maven, nothing is generated. However, with the Maven build I can run the project without changing the activity name in the manifest to <code>Activity_</code> and the project will compile and run correctly. This is very odd and seems like it could either further confuse the problem, or simplify it if it is indicative of something with Gradle as well.</p>
