    I have created a project in Android Studio: package com.example.apps.newapplication; Java code:

    import android.os.Bundle;
    import android.support.design.widget.FloatingActionButton;
    import android.support.design.widget.Snackbar;
    import android.support.v7.app.AppCompatActivity;
    import android.support.v7.widget.Toolbar;
    import android.view.View;
    import android.view.Menu;
    import android.view.MenuItem;
    import android.widget.RelativeLayout;
    import android.widget.Button;


    publicclassMainActivityextendsAppCompatActivity{

    @override
    protectedvoid onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);

    RelativeLayoutDakotasLayout=newRelativeLayout(this);
    Button redButton =newButton(this);

    DakotasLayout.addView(redButton);
    setContentView(DakotasLayout);

    Toolbar toolbar =(Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    FloatingActionButton fab =(FloatingActionButton) findViewById(R.id.fab);
    fab.setOnClickListener(newView.OnClickListener(){
    @override
    publicvoid onClick(View view){
    Snackbar.make(view,"Replace with your own action",Snackbar.LENGTH_LONG)
    .setAction("Action",null).show();
    }
    });
    }

    @override
    publicboolean onCreateOptionsMenu(Menu menu){
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    returntrue;
    }

    @override
    publicboolean onOptionsItemSelected(MenuItem item){
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if(id == R.id.action_settings){
    returntrue;
    }

    returnsuper.onOptionsItemSelected(item);
    }
    }
    Manifest.xml code:

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

    <application>
    android:allowBackup="true"
    android:icon="@Mipmap/ic_launcher"
    android:label="@String/app_name"
    android:supportsRtl="true"
    android:theme="@Style/AppTheme">
    <activity
    android:name=".MainActivity"
    android:label="@String/app_name"
    android:theme="@Style/AppTheme.NoActionBar">
    <intent-filter>
    <action android:name="android.intent.action.MAIN"/>

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

    </manifest>
    The problem is my app shuts down every time I launch it in the emulator. I'm not sure what's wrong in my java file. It might be my manifest file that's wrong, but I'm not sure.
