title: Android StrictModeDiskReadViolation when app startup
body: <p>I've enabled <code>StrictMode</code> on my app by code:</p>
  
  <pre><code>public void onCreate() {
      setStrictMode();
      super.onCreate();
  }
  
  private void setStrictMode() {
      StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
              .detectAll()
              .penaltyLog()
              .penaltyDeath()
              .build());
      StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
              .detectAll()
              .penaltyLog()
              .build());
  }
  </code></pre>
  
  <p>I found a crash when startup with log below :</p>

  <p>I think is an io operate on main thread violation, My device is samsung s6, android version 5.1.1, but I can't find the method <code>getFullFlipFont</code> anywhere, if I disable strictmode it will be alright, where is the io violation happen?</p>
