Answer 1

据Android Studio: "libpng warning: iCCP: Not recognizing known sRGB profile that has been edited"，这里是一个答案：

这只是一个警告，它的libpng开始在1.6.0版本发布，所以 你可以忽略它。

要摆脱警告，您需要修复警告中名为 的PNG文件。您可以使用任意一个PNG图像编辑器 （ImageMagick，GraphicsMagick等）删除有问题的iCCP 块。或者你可以将你的libpng降级到版本1.5.x.

看到类似的问题 libpng warning: iCCP: known incorrect sRGB profile

您可以使用ImageOptim与那些上市的图像文件，以摆脱警告，并删除：垃圾元数据和不必要的色彩配置文件。

希望它能帮助

Answer 2

正如libpng的手册页解释，你可以在自己的应用程序，以抑制有关无效sRGB配置的警告包括了这一点：

#if defined(PNG_SKIP_sRGB_CHECK_PROFILE) && \ 
    defined(PNG_SET_OPTION_SUPPORTED) 
    png_set_option(png_ptr, PNG_SKIP_sRGB_CHECK_PROFILE, 
     PNG_OPTION_ON); 
#endif 

如果你也不能编辑PNG文件或应用程序源代码，那么您只需将libpng降级到1.5.x或忽略警告（或向您的上游应用程序和映像供应商投诉）。
