libpng warning: iCCP: Not recognizing known sRGB profile that has been edited

[Guy Tavor]

Hi,

Since upgrading to the new gradle / build-tools, we keep getting this message for resources in our project:

libpng warning: iCCP: Not recognizing known sRGB profile that has been edited

Any idea what's wrong?

Can we safely ignore these?

[Philip Bergqvist]

It sounds like they can be ignored:

It's metadata added by tools like Photoshop that isn't even honored by Android. Strip it.

brew install exiftool

find . -path '*src/main/res/*' -name '*.png' -exec exiftool -overwrite_original -all= {} \;

Even if we safely ignore this warning but for apps which have log of drawable resources, the build time increases unexpectedly.

During mergeResources task , warning message for each image takes lot of time.

Is there any way i can disable these warnings ? any build options ?

[Csaba Kozák]

Check out Jake's answer above.

Jake's answer says that we should strip the images of all the metadata that is causing it.

I dont want to do this.. i only want the mergeResources to not give this warning and skip this warning without showing them on Gradle console and continue the build.

Is it possible without removing the metadata ?

[Csaba Kozák]

No.
