Be informed that we have created an apk file through command line with the help of Android SDK. Now since uploading it to google play store needs the apk to be signed. How shall we do this.

In case it help in future.
From android developer doc, remember that:
If you want to sign an app bundle from the command line, you can use jarsigner. If instead you want to sign an APK, you need to use zipalign and apksigner as described below.
So for an apk:
To align: $.\zipalign.exe -v -p 4 'C:\Users\User\Downloads\unsigned.apk' 'C:\Users\User\Downloads\aligned.apk'
To sign: $.\apksigner.bat sign --ks 'C:\Keystores\my.keystore' --out 'C:\Users\User\Downloads\signed.apk' 'C:\Users\User\Downloads\aligned.apk'
For an aab:

First you need a keystore to begin the process. You will be signing your apk with this keystore and you need to sign with same keystore for future updates. Know more about keystore here: https://developer.android.com/studio/publish/app-signing#generate-key
Once you generate the keystore, you should jarsigner
utility (which is available in JDK folder)
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore your-release-key.keystore android-release-unsigned.apk alias -storepass password
zipalign
tool(available in android SDK folder) to verify the apk.path-to-android-sdk/build-tools/version/zipalign -v 4 android-release-unsigned.apk android-prod-released-signed.apk
apksigner
tool (available in android SDK folder)path-to-android-sdk/build-tools/version/apksigner verify android-prod-released-signed.apk
PS: Replace paths, files and passwords with actual values

Follow these commands to make the apk play store ready:
Step 1: Create an unsigned apk:
./gradlew assembleRelease
Step 2: Create a signed apk:
jarsigner -keystore YOUR_KEYSTORE_PATH -storepass YOUR_KEYSTORE_PASSWORD app/build/outputs/apk/release/app-release-unsigned.apk YOUR_KEY_ALIAS
Step 3: Zipaligning the apk:
your_android-sdk_path/android-sdk/build-tools/your_build_tools_version/zipalign -v 4 app/build/outputs/apk/release/app-release-unsigned.apk release.apk

First you need to generate a private signing key
keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
This command will prompt you for a password for your keystore and key (also for some additional fields). Please remember to keep your keystore file private at anytime.
Next you need to setup gradle
my-release-key.keystore
which you generated in Step 1 under android/app
Update your ~/.gradle/gradle.properties
under android/app
and add the following
MYAPP_RELEASE_STORE_FILE=my-release-key.keystore
MYAPP_RELEASE_KEY_ALIAS=my-key-alias
MYAPP_RELEASE_STORE_PASSWORD=<The password you choose earlier with the keytool>
MYAPP_RELEASE_KEY_PASSWORD=<The password you choose earlier with the keytool>
Finally you need to update your android/app/build.gradle
.
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
}
}
}
Now you can simply generate a signed release via the command line by running the following command in your android directory
./gradlew assembleRelease
The generated apk can then be found under your build/outputs/apk/release
directory.
