title: Android: Including multiple Java Packages to Manifest
body: <p>The app I am developing has many activities organized into seven java packages. Originally I wrote all the coding and stuff for each group of activities in a java package as different projects.</p>
  
  <p>Now I'm at the point where I want to put all the packages together into one project. When I add a new package to the src folder, I get an error for all my R.id.* values ("R cannot be resolved"). </p>
  
  <p>My instinct tells me that there is something fancy I have to put in the project manifest, but I can't find any resource online to tell me how.</p>
  
  <p>(Note: I have read <a href="https://stackoverflow.com/questions/2925529/multiple-packages-in-an-android-app">this</a> and <a href="http://blog.javia.org/android-package-name/" rel="noreferrer">this</a> and I still couldn't figure out how to add additional packages to my project.)</p>
