从主要活动更改为其他活动时出现错误 - Android

我有一个使用谷歌地图的应用程序 - 直到现在它工作正常。但现在，当我想单击按钮以在地图上添加功能时，我遇到了问题。我设法在屏幕上可视化按钮，它也可以在单击时工作 - 它可以正确显示吐司。但我的目标是开始一项新活动（拥有自己的布局） - 查找和阅读教程和内容的语气就是我所拥有的：

        //the Add Button in the upper right corner
    Button addBookmark = (Button) findViewById(R.id.Button);
    addBookmark.setOnClickListener(new View.OnClickListener() 
    {
        @Override
        public void onClick(View mapView) {

            Intent addBookmarkIntent = new Intent(GoogleMapsApp.this, LocationBookmaker.class);
            startActivity(addBookmarkIntent);                                           
        }
    });

此外，我还编辑了清单文件：

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

        <activity android:name=".LocationBookmarker"
        android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.DEFAULT"/>
            </intent-filter>
        </activity>

        ...

</manifest>

无论我尝试什么，我总是得到“应用程序 GoogleMapsApp（进程 google.maps.app）已意外停止，请重试。”仅有“强制关闭”选项。

我已经尝试了两天了 - 在互联网上的很多例子中，其他人都说它应该像这样工作。我看不出我的错误在哪里。也许在意图的开始，或清单或哪里......？

原文

I have an application using the Google maps - until the moment it works fine. But now when I want to click a button in order to add functionality over the map I have problems.
I managed to visualise the button on the screen, also it works on click - it shows a toast correctly. But my aim is to start a new activity (having his own layout) - looking and reading tones of tutorials and stuff here is what I have :

        //the Add Button in the upper right corner
    Button addBookmark = (Button) findViewById(R.id.Button);
    addBookmark.setOnClickListener(new View.OnClickListener() 
    {
        @Override
        public void onClick(View mapView) {

            Intent addBookmarkIntent = new Intent(GoogleMapsApp.this, LocationBookmaker.class);
            startActivity(addBookmarkIntent);                                           
        }
    });

Also I've edited the manifest file:

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

        <activity android:name=".LocationBookmarker"
        android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.DEFAULT"/>
            </intent-filter>
        </activity>

        ...

</manifest>

No matter what I try I always get the "The Application GoogleMapsApp (process google.maps.app) has stopped unexpectedly. Please try again." with the only "Force close" option.

I've been trying since two days now - and in a lot of examples in the Internet other say it should be working like this. I cannot see where could be my mistake.
Maybe in the starting of the intent, or the manifest or where...?
