Menu xml file causing activity to immediately crash

Question

I have been stuck on this for a few days now. Whenever I open ChannelActivity it errors once it reaches setContentView(R.layout.channel_activity) Other threads I've seen were resolved by fixing an issue inside of the menu xml or by moving the menu xml into a menu resource type directory.

I still get the same errors even if my menu class has nothing inside of it, aside from xmlns:android="http://schemas.android.com/apk/res/android" and i have doubly amde sure that my menu xml was correctly placed into a menu resource type directory.

Any help as to pointing out the cause of, or fixing the error would be greaty appreciated as I'm not sure what to do at this point.

ChannelActivity:

public class ChannelActivity extends AppCompatActivity {

  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.channel_activity);   //<--------------- ERROR
  }

  public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.channel_toolbar, menu);

    return true;
  }
}

Answer 1

You inflate wrong menu xml file in onCreateOptionsMenu()

change this:

getMenuInflater().inflate(R.menu.channel_toolbar, menu);

To:

getMenuInflater().inflate(R.menu.channel_menu, menu);

Happy coding!!

Answer 2

Replace channel_activity with channel_layout and channel_toolbar with channel_menu:

public class ChannelActivity extends AppCompatActivity {

 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.channel_layout);   
 }

 public boolean onCreateOptionsMenu(Menu menu) {
  getMenuInflater().inflate(R.menu.channel_menu, menu);

  return true;
 }
}

and remove that line from channel_layout.xml file.

    <include layout="@menu/channel_toolbar"  
         android:id="@+id/channelToolbar"/>

Answer 3

You can't include menu in layout. So remove the following:

<include layout="@menu/channel_toolbar"
             android:id="@+id/channelToolbar"/>

Answer 4

Try this code I hope you will be not getting this error.
public class ChannelActivity extends AppCompatActivity {

  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.channel_layout);   //<--------------- ERROR
  }

  public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.channel_menu, menu);

    return true;
  }
}
