Ich bin neu bei Android Dev, warum bekomme ich diesen seltsamen Fehler?

das ist meine Hauptaktivität Java-Datei:Ich bin neu bei Android Dev, warum bekomme ich diesen seltsamen Fehler?

package com.example.fg; 

import android.app.Activity; 
import android.os.Bundle; 

public class MainActivity extends Activity { 

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

    } 

}

und das ist das Layout es

<?xml version="1.0" encoding="utf-8"?> 
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:fitsSystemWindows="true" 
    tools:context="com.example.fg.MainActivity"> 

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

     <android.support.v7.widget.Toolbar 
      android:id="@+id/toolbar" 
      android:layout_width="match_parent" 
      android:layout_height="?attr/actionBarSize" 
      android:background="?attr/colorPrimary" 
      app:popupTheme="@style/AppTheme.PopupOverlay" /> 

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

    <include layout="@layout/content_main" /> 

    <android.support.design.widget.FloatingActionButton 
     android:id="@+id/fab" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_gravity="bottom|end" 
     android:layout_margin="@dimen/fab_margin" 
     android:src="@android:drawable/ic_dialog_email" /> 

</android.support.design.widget.CoordinatorLayout>

und das ist der Fehler, den ich bekommen:

dies kann Ihnen helfen, http: // stackoverf low.com/questions/26561235/error-inflating-class-android-support-v7-widget-toolbar –

Versuchen Sie eine andere App: popupTheme –

der Fehler ist "Diese App wurde mit einer falschen Konfiguration erstellt. Bitte konfigurieren Sie Ihre Build für VectorDrawableCompat. "Es ist nicht das gleiche wie die eine Amit verknüpft. Diese https://stackoverflow.com/questions/38143867/why-this-app-has-bene-built-with-an- false-configuration-error-occured-in-s steht möglicherweise in Verbindung. Versuchen Sie also, die Gravel-Version zu aktualisieren, falls dies nicht möglich ist. – njzk2

Ihre Aktivität sollte sich AppCompatActivity:

public class MyActivity extends AppCompatActivity { 
    // ... 
}

XML:

<android.support.v7.widget.Toolbar 
    android:id="@+id/my_toolbar" 
    android:layout_width="match_parent" 
    android:layout_height="?attr/actionBarSize" 
    android:background="?attr/colorPrimary" 
    android:elevation="4dp" 
    android:theme="@style/ThemeOverlay.AppCompat.ActionBar" 
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>

Dann:

@Override 
     protected void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.activity_my); 
      Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar); 
      setSupportActionBar(myToolbar); 
      }
