In the manifest it has

What solved the problem for me was - create a folder "drawable" in "..platforms/android/res/" and put "icon.png" in it.
对我来说解决问题的是 - 在“..platforms/android/res/”中创建一个“drawable”文件夹并将“icon.png”放入其中。

If you are 100% sure that directories and files are ok, have a look at the project location.
如果您 100% 确定目录和文件没有问题，请查看项目位置。
There is a limit on the path length of files in the Operating System. Perhaps this limit is being exceded in your project files.
操作系统中文件的路径长度是有限制的。也许您的项目文件超出了这个限制。
Move the project to a shorter folder (say C:/MyProject) and try again!
将项目移至较短的文件夹（例如 C:/MyProject）并重试！
This was the problem for me!
这对我来说是个问题！

I've spent on this problem much time and as for me (for Intellij IDEA) the solution is to specify right path to res directory:
我在这个问题上花了很多时间，对于我（对于 Intellij IDEA），解决方案是指定 res 目录的正确路径：
- right click on project
- click Modules in the left panel
- select Android below your project name
- in Structure tab set right path.
- 右键单击项目
- 单击左侧面板中的模块
- 在您的项目名称下方选择 Android
- 在结构选项卡中设置正确的路径。
And don't forget to check all the paths in this tab!
并且不要忘记检查此选项卡中的所有路径！
I hope it will be helpful for somebody!
我希望它会对某人有所帮助！

There's an even simpler solution - delete the cache folder at user/.android/built-cache and go back to android studio and sync with gradle again, if that still doesn't work delete the cache folder again, and restart android studio and re-import the project
有一个更简单的解决方案 - 删除 user/.android/built-cache 中的缓存文件夹，然后返回 android studio 并再次与 gradle 同步，如果仍然不起作用，再次删除缓存文件夹，然后重新启动 android studio 并重新- 导入项目

Yet another Googlemare Landmine.... Somehow, if you mess up, the icon line on your .gen file dies. (Empirical proof of mine after struggling 2 hours)
又一个 Googlemare Landmine ......不知何故，如果你搞砸了，你的 .gen 文件上的图标行就会消失。（我挣扎了 2 小时后的经验证明）
Insert a new icon 72x72 icon on the hdpi folder with a different name from the original, and update the name on the manifest also.
在 hdpi 文件夹中插入一个新图标 72x72 图标，其名称与原始图标不同，并更新清单上的名称。
The icon somehow resurrects on the Gen file and voila!! time to move on.
图标不知何故在 Gen 文件上复活了，瞧！！分手后要往前看了。

This happens when you have previously changed your icon or the ic_launcher; and when that ic_launcher no longer exists in your base folder.
当您之前更改了图标或 ic_launcher 时会发生这种情况；当您的基本文件夹中不再存在该 ic_launcher 时。
Try adding a png image and giving the same name and then copy it to your drawable folder.Now re build the project.
尝试添加一个 png 图像并赋予相同的名称，然后将其复制到您的可绘制文件夹。现在重新构建项目。

我有这个问题。我用 jpg 格式为我的背景创建了一张图片。在添加这张图片之前，我将格式更改为 png 并重命名格式。然后我和你一样遇到了这个错误。我用photoshop之类的图片编辑器将我的格式图片更改为png，并在我的项目中用图片替换它，然后我没有那个错误。对不起英语不好
