Description

When I was trying to generate signed APK with Android Studio, I am getting duplicate resource error.
Error log:

I have faced similar issue yesterday. Removing the raw folder from
/Users/ad/Documents/react-native-project/android/app/src/main/res/ worked for me!

This might help facebook/react-native#22234 (comment).

add this into node_modules/react-native/react.gradle file

def flavorPathSegment = ""
android.productFlavors.all { flavor ->
if (targetName.toLowerCase().contains(flavor.name)) {
                    flavorPathSegment = flavor.name
            }
            }

            doLast {
                def moveFunc = { resSuffix ->
                    File originalDir = file("$buildDir/generated/res/react/${flavorPathSegment}release/drawable-${resSuffix}")
                    if (originalDir.exists()) {
                        File destDir = file("$buildDir/../src/main/res/drawable-${resSuffix}")
                        ant.move(file: originalDir, tofile: destDir)
                    }
                }
                def moveRawFunc = { dir ->
                    File originalDir = file("$buildDir/generated/res/react/${flavorPathSegment}release/${dir}")
                    if (originalDir.exists()) {
                        File destDir = file("$buildDir/../src/main/res/${dir}")
                        ant.move(file: originalDir, tofile: destDir)
                    }
                }

                moveFunc.curry("ldpi").call()
                moveFunc.curry("mdpi").call()
                moveFunc.curry("hdpi").call()
                moveFunc.curry("xhdpi").call()
                moveFunc.curry("xxhdpi").call()
                moveFunc.curry("xxxhdpi").call()
                moveRawFunc.curry("raw").call()
            }
