Keyboard Hidden crashes on android Lollipop

Does anyone solve the problem with keyboard hidden crash on android 5.0? I've tried on 4.4.2 with the same code but it doesn't happen.

This is my activity settings:

<activity
        android:name=".activity.MainActivity"
        android:configChanges="orientation|screenSize"
        android:hardwareAccelerated="true"
        android:label="@string/app_name"
        android:screenOrientation="portrait"
        android:theme="@style/AppTheme.NoActionBar">

This is the log after freezing
