You need to first generate a private key using keytool, For Example:
keytool -genkey -v -keystore my-release-key.jks-keyalg RSA -keysize 2048 -validity 10000 -alias my-alias
The keystore as a file called my-release-key.jks, saving it in the current directory (you can move it wherever you'd like). The keystore contains a single key that is valid for 10,000 days
Sign your app manually from the command line

step 1: Open Android Studio, select View > Tool Windows > Terminal—and navigate directory where unsigned APK.
step 2: unsigned APK using zipalign:

**step 3:**APK with your private key using apksigner:
apksigner sign --ks my-release-key.jks --out my-app-release.apk my-app-unsigned-aligned.apk
