Description

I migrated from 0.55.4 to 0.56.0 and now ProGuard is failing my Android build. I think Fresco is getting one of its dependencies eliminated by ProGuard, so we need to write a keep line to prevent this. It would be nice to add this to the changelog of 0.56. Or alternatively, should react-native-upgrade do this automatically? I looked at your proguard template files, and they don't seem to have any lines that would fix this. I guess this may have just slipped under the radar.

10:16:29.581 [ERROR] [system.err] Warning: com.facebook.imagepipeline.nativecode.StaticWebpNativeLoader: can't find referenced class com.facebook.common.soloader.SoLoaderShim
10:16:29.581 [ERROR] [system.err] Warning: com.facebook.imagepipeline.nativecode.StaticWebpNativeLoader: can't find referenced class com.facebook.common.soloader.SoLoaderShim
10:16:31.897 [ERROR] [system.err] Warning: there were 2 unresolved references to classes or interfaces

Reproduction

Upgrade to rn 0.56, turn on proguard, and try to build the android project with Facebook's built in proguard template. Observe that the above class is not found by Fresco and fails the build.

Solution

Someone needs to write a keep rule for this and either document it or make Fresco automatically share its proguard config

[luisnaranjo733]

Worth noting I'm on implementation 'com.facebook.fresco:webpsupport:1.3.0'.

I just upgraded to 1.10.0 to see what would happen and now I'm getting more ProGuard errors.

According to the Fresco docs, 1.9.0 and up ship with a built in proguard config that will be automatically applied. Is there something else I have to do in order to get the latest ProGuard config?

[luisnaranjo733]

So, I've realized this is partially my own fault:

I only had this line in my build.gradle

    implementation 'com.facebook.fresco:webpsupport:1.3.0'

and now I have

    implementation 'com.facebook.fresco:fresco:1.10.0'
    implementation 'com.facebook.fresco:webpsupport:1.10.0'

However, the issue is still present, just now there are only 6 warnings from proguard regarding SoLoader that aren't covered by the built in proguard config fresco is shipping automatically.

It looks like you're including SoLoader in both Fresco and React Native. I guess you have to exclude the dependency (com.facebook.soloader:soloader:...)

[luisnaranjo733]

I ended up solving this by downgrading to Fresco 1.9

[oprisnik]

Yes, you always have to use the same version as React Native as well. Glad you fixed the issue.
