Challenges Faced Building an Android APK file for local release.

You can visit the React-Native documentation for the actual release of your application. Click Here

In this article, we will discuss the local release of the application for Android.

1. Build APK Key:

   go to the JDK directory in your C:\Program Files\jdkfolder\bin open the terminal paste the below command and set the password and remaining fields. Once you successfully run the command the my-upload-key.keystore the file is created inside the bin folder move the created file into yourapplication/android/app and paste it there.

    keytool -genkeypair -v -keystore my-release-key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias my-key-alias
   

2. Set Up Gradle for Release:

   Edit android/gradle.properties to include the following (replace placeholders with your actual key information):

    MYAPP_RELEASE_STORE_FILE=my-release-key.jks
    MYAPP_RELEASE_KEY_ALIAS=my-key-alias
    MYAPP_RELEASE_STORE_PASSWORD=your-store-password
    MYAPP_RELEASE_KEY_PASSWORD=your-key-password
   

   Edit android/app/build.gradle to add the signing configuration:

    android {
        ...
        defaultConfig { ... }
        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
                }
            }
        }
        buildTypes {
            release {
                signingConfig signingConfigs.release
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            }
        }
    }
   

3. Generate the JavaScript Bundle:

    npx 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/
   

4. Build the Release APK:

    cd android
    ./gradlew assembleRelease
   

5. Problem: ENOENT: no such file or directory for index.android.bundle

   Issue: The error indicates that the index.android.bundle file or assets directory doesn't exist.

   i. Create the Assets Directory:

    mkdir -p android/app/src/main/assets
   

   ii. Again Generate the Javascript Bundle [step 3]

6. If the build is successful then you will find the apk file at yourapplication\android\app\build\outputs\apk\release location.
