Android studio: Myapp stopped working.

[gridle]

Ik ben vrij nieuw met android studio, maar heb nu al een probleem. Ik gebruik de ADM, maar elke keer als ik mijn app start krijg ik: appnaam stopped working. Om te kijken of het aan mijn code lag heb ik een nieuw project gemaakt en zonder iets erin te zetten de app op het virtal machine proberen te draaien, maar zelfde probleem. Ik weet niet eens waar ik moet beginnen. Heb het all proberen te googlen maar kom ik niet uit.
...
Mijn Code is dus:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.onrus.myapplication">

<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

</manifest>

En:

package com.example.onrus.myapplication;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

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

Deze error krijg ik in de run na het runnen:

Zo zonder code-tags is het natuurlijk totaal niet te lezen, maar vooruit.

Als je googlet op 'java.lang.NoClassDefFoundError: Failed resolution of: Landroid/support/v7/appcompat/R$styleable;' vind je onder andere dit: https://stackoverflow.com...upport-v7-appcompat-rstyl

Kan je ook eens het gradle-bestand hier posten?

Hoeveel posts heb je gezien die geen gebruik maken van code tags? En hoe moeilijk is het om dit zelf toe te passen. Als je daar al geen onderzoek naar wilt doen...
