@Joseph Roque is correct, you need to update the version numbers in android/app/build.gradle.

Here's how I automate this and tie it into the package's version in package.json and git commits.

In android/app/build.gradle:

/* Near the top */

import groovy.json.JsonSlurper

def getNpmVersion() {
    def inputFile = new File("../package.json")
    def packageJson = new JsonSlurper().parseText(inputFile.text)
    return packageJson["version"]
}
/* calculated from git commits to give sequential integers */
def getGitVersion() {
    def process = "git rev-list master --first-parent --count".execute()
    return process.text.toInteger()
}


......


def userVer = getNpmVersion()
def googleVer = getGitVersion()

android {
...
    defaultConfig {
        .....
        versionCode googleVer
        versionName userVer

        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
    }

Notes:

• It's important that versionCode is an integer - so we can't use semantic versioning here. This is used on the play store to tell which versions come after others - that's why it's tied to git commits in getGitVersion

• versionName however is shown to users - I'm using semantic versioning here and storing the real value in my package.json. Thanks to https://medium.com/@andr3wjack/versioning-react-native-apps-407469707661
