Use findViewById after setting your setContentView(R.layout.activity_main)

realm on sdk 16(Jelly Bean) without rxjava crashing

Important details
I have added the dummy class listed here
https://realm.io/docs/java/latest/#jackson-databind
And everything works well on Lollipop but as soon as I created a Genymotion emulator for 4.1 Jelly Bean and try to push the application I get the errors listed below which looks like it is trying to resolve the OnSubscribe interface defined within rxjava Observable which I am dummying.
I was not using Proguard for the below stack, but after setting it up I am getting the same.
Is this expected and should be ignored? I have one or two other warn messages I am trying to track down as well.

As it turns out this was not what was causing the Application to crash, it was just one of the many error messages being logged when running on dalvik instead of Art.
The issue I encountered was trying to run an app that was using Google Services on a version before 4.2.2 as instructed here.
https://developers.google.com/android/guides/setup
"The Android emulator with an AVD that runs the Google APIs platform based on Android 4.2.2 or higher."
So I still see the following error when deploying but the app seems to be functioning correctly.

In Realm documentation, specific section about Jackson say that the solucion is adding RxJAVA dependency in your project.
In my personal case, it's worked.

NoClassDefFoundError for socket.io on a background service when using multidex

However when i start my service my app crashes and i get the following error

I think that this exception is thrown because of not adding MultiDex.install() in the MyService class but on the other whenever i try to add it i get another exception

GridLayout (Support Version) - Android 2.3.3

I am developing for Android 2.3.3 and attempting to use the support GridLayout.
After SetContentView is run on onCreate in a class I am using, my app crashes.
I have the following GridLayout in a view:
<android.support.v7.widget.GridLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/chaptergrid"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:columnCount="4">
</android.support.v7.widget.GridLayout>
And I get the following in the Log Cat:
