Creating the Release Build Apk for Android or React Native
Step 1. Generate a keystore
your_key_name can be any name you want to put for your project.
amitgupta@Amits-MacBook-Pro MyApplication > keytool -genkey -v -keystore your_key_name.keystore -alias your_key_name -keyalg RSA -keysize 2048 -validity 10000
Enter keystore password:
Re-enter new password:
What is your first and last name?
[Unknown]: Amit Gupta
What is the name of your organizational unit?
[Unknown]: MS
What is the name of your organization?
[Unknown]: Lists
What is the name of your City or Locality?
[Unknown]: HY
What is the name of your State or Province?
[Unknown]: TL
What is the two-letter country code for this unit?
[Unknown]: IN
Is CN=Amit Gupta, OU=MS, O=Lists, L=HY, ST=TL, C=IN correct?
[no]: yes
Generating 2,048 bit RSA key pair and self-signed certificate (SHA256withRSA) with a validity of 10,000 days
for: CN=Amit Gupta, OU=MS, O=Lists, L=HY, ST=TL, C=IN
[Storing android-blank-app.keystore]
Here I use your_key_name as “android-blank-app” shown in output.
Step 2. Adding Keystore to your project
amitgupta@Amits-MacBook-Pro MyApplication > mv android-blank-app.keystore /app
Or You can just move keystore file by drag and drop from your android studio from MyApplication Folder to app folder.
Step3. Add keystore into app/build.gradle
signingConfigs {
release {
storeFile file('android-blank-app.keystore')
storePassword 'password_which_you_entered_during_key_creation'
keyAlias 'android-blank-app'
keyPassword 'password_which_you_entered_during_key_creation'
}
}
buildTypes {
release {
signingConfig signingConfigs.release
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
If you want to run the Release Build on your Android Studio Project then you can use command like:
> ./gradlew assembleRelease
If It is react Native Project then you can run the following command:
> $ 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/
> cd android
> ./gradlew assembleRelease
It is complete now . Thanks for reading the content.
