android.view.InflateException: Binary XML file line #7: Binary XML file line #7: Error inflating class fragment

i,ve just implemented my 4th tab into my application which has google maps implemented. before this implementation my application ran fine, now when i change tab it crashes. i have seen similar questions asked on here, but NOT ONE HAS THE ANSWER LOL(there was actually so many different causes and responses to this issue)

here is the fragmentshouts_maps class

package com.example.hp_user.shoutfinal28;



import android.os.Bundle;

import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;


public class FragmentShouts_Maps extends Fragment implements OnMapReadyCallback {


public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Get the view from fragment shouts.xml
    View root_view = inflater.inflate(R.layout.fragmentshouts_maps, container, false);
    SupportMapFragment supportMapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.Maps1);
    if (supportMapFragment!= null) {
        supportMapFragment.getMapAsync(this);
    }
    return root_view;
}


@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
}

@Override
public void onMapReady (GoogleMap map) {
    map.addMarker(new MarkerOptions()
            .position(new LatLng(0, 0))
            .title("Marker"));
}
