更改壁纸意图 应用程序在 Nook Color 中崩溃：
我需要为 Nook Color 开发一个壁纸应用程序。之后我安装了 Nook 颜色插件，当我在我的应用程序中使用此代码时，它每次都会崩溃。以下 API 意图允许任何应用程序在 Nook Color 设备中打开壁纸设置管理器 UI
Intent i = new Intent();
i.setAction( "com.bn.nook.CHANGE_WALLPAPER" );
startActivity( i );
Error: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.bn.nook.CHANGE_WALLPAPER }
请帮忙，提前致谢。

此意图仅在 Nook 设备上可用。
在任何其他不是专门设计为角落的设备或模拟器上使用它是行不通的。
这就像尝试在未安装 Internet Explorer 的计算机上打开 Internet Explorer 一样。
This intent is only going to be available on Nook device.
Using this on any other device or emulator that isn't specifically designed to be the nook isn't going to work.
It would be like trying to open Internet Explorer on a machine which doesn't have Internet Explorer installed.
您发布的代码是（我假设）官方Nook开发者页面的直接复制粘贴 这里。
该代码本质上并不是错误的，您指定的操作似乎根本不存在 - 您需要从 Developers/Nook API 中找到正确的操作名称。
The code you have posted is a direct copy paste from (i assume) the official Nook Developer page here.
The code isn't inherently wrong, the Action your specifying simply doesn't seem to exist - you need to find the correct Action name from the Developers/Nook API.
