android.view.InflateException: Binary XML file line #30: Binary XML file line #30: Error inflating class <unknown>

Question

I am making a custom adapter in card view which loads data from a locally saved json file. I am able to fetch the data but the view is not being inflated and I keep on getting this error:

My Custom Adapter class:

package com.example.visan.pulse;

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import android.widget.TextView;

import java.util.List;

public class CardAdapter extends RecyclerView.Adapter<CardAdapter.ViewHolder>{
    private List<Data> dataSet;
    private Context context;

public CardAdapter(List<Data> dataSet, Context context){
    super();
    this.dataSet=dataSet;
    this.context=context;
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View v = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.card_layout, parent, false);
    ViewHolder viewHolder=new ViewHolder(v);
    return viewHolder;
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {
    Data data=dataSet.get(position);
    holder.event.setText(data.getName());
    holder.venue.setText(data.getVenue());
    holder.time.setText(data.getTime());
    holder.notify.setImageResource(R.drawable.ic_action_bell);
    holder.main.setImageResource(R.drawable.image_16);
}

@Override
public int getItemCount() {
    return dataSet.size();
}

public class ViewHolder extends RecyclerView.ViewHolder{
    public TextView event,venue,time;
    public ImageView main,notify;

    public ViewHolder(View itemView){
        super(itemView);
        main=(ImageView) itemView.findViewById(R.id.card_image);

        venue=(TextView) itemView.findViewById(R.id.textView_venue);

Text appearance attribute shouldn't be applied to android:textSize. Do this:

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textAppearance="?android:textAppearanceLarge"
            android:id="@+id/textView_event"/>
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textAppearance="?android:textAppearanceSmall"
            android:id="@+id/textView_time"/>
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textAppearance="?android:textAppearanceSmall"
            android:id="@+id/textView_venue"/>
