Answer 1

The steps above really helped.

Here's the scripts that work for us with react-native 0.55.3.

Run the android-build command locally or CI to generate an APK.

/packages.json (react-native):

"android-bundle": "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",
"android-release-fix": "node ./android-release-gradle-fix.js",
"android-build": "yarn killbin && yarn android-clean && yarn android-release-fix && yarn android-bundle && cd android && ./gradlew assembleRelease -x bundleReleaseJsAndAssets --info",
"android-clean": "cd android && ./gradlew clean",
"killbin": "rm -rf ./node_modules/.bin",

android-release-gradle-fix.js:

const fs = require('fs')

// Fix issues with Android resources like duplicate files
// CI: run install with --unsafe-perm option

try {
        var curDir = __dirname
        var rootDir = process.cwd()

        var file = `${rootDir}/node_modules/react-native/react.gradle`
        var dataFix = fs.readFileSync(`${curDir}/android-react-gradle-fix`, 'utf8')
        var data = fs.readFileSync(file, 'utf8')

        var doLast = "doLast \{"
        if (data.indexOf(doLast) !== -1) {
            throw "Already fixed."
        }

        var result = data.replace(/                \/\/ Set up inputs and outputs so gradle can cache the result/g, dataFix);
        fs.writeFileSync(file, result, 'utf8')
        console.log('Done')
    } catch (error) {
        console.error(error)
    }

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)
