android livewallpaper设置按钮单击导致错误 - 不幸的是，动态壁纸选择器已停止

标签： java android crash libgdx live-wallpaper

我正在尝试使用libgdx库在Android中制作动态壁纸应用程序，但我有一个问题。每当在动态壁纸选择器中按下设置按钮时，应用程序崩溃并显示消息：“不幸的是，动态壁纸选择器已停止”，否则一切正常。

我一直在关注这个例子： How to create android live wallpaper

我尝试在这里寻找解决方案，例如： Live Wallpaper crash when tap on Settings

但没有什么能解决我的问题 - 我认为它在某个地方的xml文件中，但也许将libgdx与livewallpaper结合起来会有问题？

我一直试图找到解决方案，但不能，真的很感激一些帮助。

这是我的代码：

答案 0 :(得分：0)

我发现了问题，我错误地引用了“LivewallpaperSettings.java” “wallpaper.xml”文件中的类：

代替： 机器人：settingsActivity =“lwp.example.android.LivewallpaperSettings

它应该是： 机器人：settingsActivity = “com.mygdx.game.android.LivewallpaperSettings”

我使用了另一个项目作为参考并复制它而不将其更改为正确的路径。抱歉..浪费了我的时间和其他人：/

感谢您的帮助。
