Rejecting re-init on previously-failed class java.lang.Class<android.support.v4.view.ViewCompat$OnUnhandledKeyEventListenerWrapper> supportLib=28 : <p>This weird logcat messages started when I switched to supportLibrary 28, not happens on 27.1.1. I tried with an empty default project and the result exactly the same.</p>

<p>The problem is easily reproducible,</p>

<p>Create a new project with an empty activity and run on an emulator except API28 emulator. It'll give that error on my API21 emulator:</p>

<pre><code>Rejecting re-init on previously-failed class java.lang.Class&lt;android.support.v4.view.ViewCompat$OnUnhandledKeyEventListenerWrapper&gt;
</code></pre>

<p>My API24 device shows more detailed log:</p>

<p>I tried API21 emulator, API24 hardware device and API 28 emulator. Only API28 emulator didn't produce that error.</p>

<p>I googled, searched SO and also reported to <a href="https://issuetracker.google.com/issues/117685087" rel="noreferrer">android issue tracker</a> I can't find any solution and android team says that is an intended behavior. So I don't know what to do. Should I ignore an error message? Is there anybody have this issue? </p>
