Android app crashes on startup(Error inflating class android.support.v7.internal.widget.ActionBarContextView)

Question

I have followed the tutorial Here and have made an Android app in Android studio. However, The app crashes on start up and I get this error:

03-09 13:08:39.597 27112-27112/com.test.test E/AndroidRuntime: FATAL EXCEPTION: main  03-09 13:08:39.597 27112-27112/com.test.test E/AndroidRuntime: java.lang.RuntimeException: Unable to start activity   ComponentInfo{com.test.test/com.test.test.MainActivity}: android.view.InflateException: Binary XML file line #43: Error inflating class android.support.v7.internal.widget.ActionBarContextView

I have tried many solutions which have worked for others but I am having no such luck. Is there any way to resolve this? If any code is needed then ask and i will post it. I have already tried the solutions provided Here,hereand here So, those solutions won't help.

Thanks in advance:)

EDIT:

Here is the main activity:

package com.test.test;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.Menu;
import android.view.MenuItem;

public class MainActivity extends AppCompatActivity implements topfrag.topfragListener {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

@Override
public void createPic(String top, String bottom) {
   picfrag bfrag=(picfrag)getSupportFragmentManager().findFragmentById(R.id.fragment2);
  bfrag.setPicText(top,bottom);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
 }
}

EDIT: Here is the activity_main.xml XML file

You have an error in your xml line 43. The xml you posted is shorter than 43 lines. — barq, Mar 09 '16 at 08:15
The one that contains the line where you are getting the error. — barq, Mar 09 '16 at 08:16
@barq It doesn't say which file has the error and all the xml fills i see have less than 43 lines. — Paul, Mar 09 '16 at 08:17

Sorry, you followed a youtube video without having access to the author's source code? And in the video he is nowhere showing the xml for activity_main.xml or any other layout xml he is using. How on earth you managed to complete this course?

From his github I found the project in the video: https://github.com/buckyroberts/Source-Code-from-Tutorials/tree/master/Android_Beginners/023-030_DankMeme/java but it is missing all the resources (it has only the java classes).

Anyway for start I think in your activity_main.xml you are missing the closing tag of RelativeLayout in the end of the file: </RelativeLayout>. You IDE is not complaining about not closing it?

I suspect that even if you correct this, other errors will emerge. Try to find the complete source code of this course else follow another tutorial.

Downvoters please post a comment explaining the reasons. thanks – pleft Mar 09 '16 at 09:07
The video was the final video in a play list. He showed the entire project in those videos. Also, the /RelativeLayout is in my code, I just didn't select when i was posting it. – Paul Mar 09 '16 at 09:07

@Paul But the youtube link you posted did not contain it. Please be more specific in your question and provide valid data. There are two more layout `xml`s in the project, you could at least post them too! – pleft Mar 09 '16 at 09:10
I posted the other XML files. Sorry for the delay, My Internet stopped working for a bit. Thanks for your patience:) – Paul Mar 09 '16 at 11:03
