title: VFY: unable to resolve [lots of stuff]
body: <p>I came back to work today and I started debugging my app using the emulator (KitKat), and my app runs ok. I had made some changes since last Friday, but not much.</p>
  
  <p>Then I moved to the device (Gingerbread) and notices the app, that was working last week, had started to crash right on main activity's <code>setContentView()</code>. Here are the warning/error messages:</p>
  
  <pre><code>W/ActivityThread﹕ Application com.example.myapp is waiting for the debugger on port 8100...
  W/dalvikvm﹕ VFY: unable to resolve static method 790: Landroid/net/TrafficStats;.setThreadStatsTag (I)V
  W/dalvikvm﹕ VFY: unable to resolve instance field 50
  W/dalvikvm﹕ VFY: unable to resolve virtual method 95: Landroid/app/Activity;.getFragmentManager ()Landroid/app/FragmentManager;

  W/dalvikvm﹕ VFY: unable to resolve new-instance 6818 (Lmaps/c/i;) in Lmaps/e/al;
  </code></pre>
  
  <p>All these messages appear after the <code>setContentView</code> method.</p>
  
  <p>I noticed that it mentions <code>getFragmentManager</code>, however that's not part of my app. Since it has API 9 compatibility, I'm using the AppCompat v7, <code>getSupportFragmentManager</code> and including the <code>Support</code>everywhere it is needed.</p>
  
  <p>I've undone the changes I did earlier today, but it still doesn't work.
  Is it possible that the appcompat lib was updated recently? I'm using Gradle to get most of them:</p>
  
  <pre><code>dependencies {
      compile 'com.android.support:appcompat-v7:+'
      compile 'com.google.android.gms:play-services:+@aar'
      compile 'com.google.code.gson:gson:+@jar'
      compile 'com.google.zxing:android-integration:+@jar'
      compile 'com.googlecode.libphonenumber:libphonenumber:+@jar'
      compile 'com.intellij:annotations:12.0'
      compile fileTree(dir: 'libs', include: ['*.jar'])
      compile project(':Facebook')
  }
  </code></pre>
  
  <p>I don't know how to debug these VFY errors. What can I do to try to solve them?</p>
