Android app always show app name in toolbar

Issue

I want to show a specific text in my app toolbar but it also always shows the name of the app too. How can I get rid of the app name and only the text of the TextView?

<android.support.design.widget.AppBarLayout
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:theme="@style/AppTheme.AppBarOverlay"
    android:fitsSystemWindows="true" >

    <android.support.v7.widget.Toolbar
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:minHeight="?attr/actionBarSize"
        app:popupTheme="@style/AppTheme.PopupOverlay"
        android:fitsSystemWindows="true" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:gravity="left"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:text="The title I want to show"
            android:layout_alignParentTop="true"
            android:layout_alignParentStart="true" />

    </android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>

Solution

Add label to activity declaration in AndroidManifest.xml file.

    <activity
        ....
        android:label="Name of Your Screen"
        ....
    </activity>
