完成效果：拨打电话，发送短信，播放音乐，播放视频，打开网页，查看图片，通知栏。

PopWindow中完成效果：拍照片，从相册选择照片并且可裁减。

首先在清单文件中加入如下权限：

<uses-permission android:name="android.permission.CALL_PHONE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
