In this article, we will learn how to create a release key store for Android app and then sign it.
Requirements:
1. Create private keystore
Make sure keytool command is global available (You can find in C:\Program Files (x86)\Java\jdk1.8.0_181\bin).
keytool -genkeypair -v -keystore <RELEASE_KEY_PATH> -alias <RELEASE_KEY_ALIAS> -keyalg RSA -keysize 2048 -validity 10000
Example:
2. Apply zipalign
The zipalign file alignment tool makes it possible to greatly optimize Android application (APK) files.
I have Android Studio installed, so my Android SDK location is C:\Program Files (x86)\Android\android-sdk.
You have to use the latest Android SDK installed path. In my case is C:\Program Files (x86)\Android\android-sdk\build-tools\27.0.3.
The APK_UNSIGNED_PATH is a Release APK.
zipalign -f -v 4 <APK_UNSIGNED_PATH> <APK_PATH>
3. Sign APK
In the same path from step 2.
apksigner sign --ks <RELEASE_KEY_PATH> --ks-key-alias <RELEASE_KEY_ALIAS> <APK_SIGNED_PATH>
Verify signature in APK:
apksigner verify <APK_SIGNED_PATH>
If everything is correct you won't see errors in the console.
