Add the following code to file node_modules/react-native/react.gradle :

doLast {
    def moveFunc = { resSuffix ->
        File originalDir = file("${resourcesDir}/drawable-${resSuffix}")
        if (originalDir.exists()) {
            File destDir = file("${resourcesDir}/drawable-${resSuffix}-v4")
            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()
}

inside def currentBundleTask = tasks.create(...

Found this temporary solution here.

@PierreBresson
seems not work with 0.57.0 , work fine with 0.55 🤔

pppluto on Sep 15, 2018

Thanks for posting this! It looks like your issue may refer to an older version of React Native. Can you reproduce the issue on the latest release, v0.55?

Thank you for your contributions.

react-native-bot on May 10, 2018

I’ve upgraded my react native to 57.7 react to 16.3.2 build tools gradle to 3.2.0 gradle to 4.6

and removed all drawable* folders

rm -rf android/app/src/main/res/drawable-*

from gradle.properties remove android.enableAapt2=false

#use the following command to bundle assets:

react-native bundle --platform android --dev false --entry-file index.android.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/build/intermediates/res/merged/release/

now generate release apk using following command. cd android && ./gradlew assembleRelease && cd ..

Note: bundled assets folder in RN > 57 has changed to android/app/build/intermediates/res/merged/release/

GaneshSaiKumar on Dec 18, 2018

@zszep yes @PierreBresson code solved it

Here’s how i generate signed apk for android now:

first i update jsbundle by this command

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

then Generate Signed apk as usual with android studio.

akamahesh on May 19, 2018

I moved image files from drawble-mdpi to drawable-hdpi directory. Now it is working fine!

TheHemantKaushik on Aug 14, 2018

well, i solved in this way:

in gradle-wrapper.properties use distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-all.zip
in gradle. properties remove enableAappt2=false
in android>build.gradle set

`buildscript {
    repositories {
       
        google()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        } 
        jcenter()
    }
    dependencies {
       classpath 'com.android.tools.build:gradle:3.2.0'

    }
}

allprojects {

        mavenLocal()

            name 'Google'
        }  
        jcenter()
        google()
        configurations.all {
            resolutionStrategy {

@7laria’s answer worked for me. Well, part of the answer did the trick. Along with step 1 and 2, just updated com.android.tools.build:gradle to 3.2.0
