Android StrictModeDiskReadViolation when app startup
<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>StrictMode policy violation; ~duration=0 ms: android.os.StrictMode$StrictModeDiskReadViolation: policy=95 violation=2

<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>
