How to Generate a React Native Release Build APK for Android

in this video tutorial i will explain how you can create release apk for android.

Generating an upload key

You can generate a private signing key using keytool. On Windows keytool must be run from C:\Program Files\Java\jdkx.x.x_x\bin.

First Step go to the project root directory. 

Write the cmd and open the command prompt 

Generating an upload key 

The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app, so remember to take note of the alias.

Note: Remember to keep your keystore file private and never commit it to version control.

press enter then it will start process to generate.

my-release-key.keystore file need to put the android/app folder.

gradle.properties setup

MYAPP_RELEASE_STORE_FILE=my-release-key.keystore

MYAPP_RELEASE_KEY_ALIAS=my-key-alias

MYAPP_RELEASE_STORE_PASSWORD=enter your password here

MYAPP_RELEASE_KEY_PASSWORD=enter your password here

  android/app/build.gradle

defaultConfig  Section add this codding

signingConfigs {

        release {

            if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {

                storeFile file(MYAPP_RELEASE_STORE_FILE)

                storePassword MYAPP_RELEASE_STORE_PASSWORD

                keyAlias MYAPP_RELEASE_KEY_ALIAS

                keyPassword MYAPP_RELEASE_KEY_PASSWORD

            }

        }

    }

Built type need to add those line

signingConfig signingConfigs.release

Now you need to process some command in cmd go to the cd android folder

Now enter the command .\gradlew clean. its means it will clean the previous apk. and it will generate again. if your apk is stopped working you need to generate this .\ gradlew assembleRelease –stacktrace

if you found more error ./gradlew --warning-mode=all 

if gradlew is giving any error run the command ./gradlew --stop

Run this command to generate sign in apk gradlew assembleRelease

after generating the apk. you will find apk here 

android\app\build\outputs\apk\release

if you find any problem with generating apk you can knock me into the command section below.

Have a good day!
