我嘗試解決此問題的一些基本方法:
Some basic things i've tried to solve this issue:
- 使緩存失效/重啟
- 刪除 gradle 文件夾
推薦答案
很可能是 JPG 重命名為 PNG 文件，而不是實際的 PNG 文件
問題可能是由于圖像的錯誤擴展名造成的.
就我而言，該文件是 JPEG 圖像，但它保存為 PNG 未轉換為.在這種情況下，將擴展名更改為真實的擴展名并轉換為 PNG，然后重試.
It's likely a JPG renamed to a PNG file, not an actual PNG file
The problem could be because of the wrong extension of images.
In my case, the file was a JPEG image but it was saved as PNG not converted to. In this situation change extension to the real one and convert to PNG then retry.
例如，您有 ic_logo.png，但它實際上是 JPG 圖片.
您應該將其重命名為 ic_logo.jpg 并使用 Photoshop 之類的工具將圖像轉換為 PNG 格式.
For instance, you have ic_logo.png but it's actually a JPG image.
You should rename it back to ic_logo.jpg and use something like Photoshop to convert the image to PNG format.
