Problems with startActivity error Channel is unrecoverably Broken and will be disposed!

Question

My application is closing unexpectedly while doing a button event in the top menu. When this happens nothing is appearing in the Logcat I’m following the pattern like this:

Within a activity I put the método onOptionsItemSelected next:

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();

    if(id == R.id.favoritar){
        if (!restaurante.isFavorito()) {
            // Adiciona aos favoritos
            adicionarAosFavoritos();
        } else {
            // Remove
            removerDosFavoritos();
        }
    }else{
        Intent comentariosActivity = new Intent(getContext(), Comentarios.class); //Aqui é onde ta ocorrendo o error.
        startActivity(comentariosActivity);
        //Toast.makeText(getActivity(), "testando",  Toast.LENGTH_SHORT).show();
    }

    return super.onOptionsItemSelected(item);
}

In my classe java ComentariosActivity I do so:

package com.fomedemais.FomeDemais;

import android.os.Bundle;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.widget.Toolbar;
import com.fomedemais.FomeDemais.entity.retornos.Comentarios;
import org.androidannotations.annotations.EActivity;

import java.util.ArrayList;

@EActivity(R.layout.activity_comentarios)
public class ComentariosActivity extends ActionBarActivity {

ArrayList<Comentarios> lstComentarios;

private Toolbar mToolbar;
private NavigationDrawerFragment mNavigationDrawerFragment;
public static final String BACKSTACK = "backstack";


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
    mToolbar.setTitle("");
    setSupportActionBar(mToolbar);
    getSupportActionBar().setDisplayShowHomeEnabled(true);

    mNavigationDrawerFragment = (NavigationDrawerFragment) getFragmentManager()
            .findFragmentById(R.id.fragment_drawer);
    mNavigationDrawerFragment.setup(R.id.fragment_drawer,
            (DrawerLayout) findViewById(R.id.drawer), mToolbar);
 }
}

And in my activity I do so:

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="4dp"
    android:paddingRight="4dp"
    android:paddingTop="4dp"
    android:paddingBottom="4dp"
    tools:context=".MainActivity"
    android:background="#ff6eb6ff"
    android:onClick="startSecondActivity">


<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:text="DRAGÃO"
    android:id="@+id/textView"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"
    android:textSize="@dimen/abc_text_size_display_3_material"
    android:textColor="#ffffffff" />
</RelativeLayout>

If there is something I can do to check the error, initially I just want to make the screen appear.

This mistake was spit on the screen:

After the amendment of AndroidManifest being like this:

 <activity
      android:name="ComentariosActivity"
      android:label="@string/app_name"
      android:screenOrientation="portrait" />

another error occurred:
