keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000
  • Replace my-release-key.keystore with your desired keystore file name.
  • Replace alias_name with a descriptive alias (e.g., your app's name).
  • -keyalg RSA specifies the algorithm (RSA is recommended).
  • -keysize 2048 sets the key size (higher is more secure).
  • -validity 10000 sets the validity period in days (10000 days is approximately 27 years).

You'll be prompted to provide a password for your keystore and information about your organization.

  1. Sign the APK: After building your APK (usually a *.apk file), you'll use the jarsigner tool (also part of the JDK) to sign it:
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore my-app-unsigned.apk alias_name
  • Replace my-app-unsigned.apk with the path to your unsigned APK file.
  • Replace alias_name with the alias you used when creating the keystore.
  1. Align the APK (Optional but Recommended): This step optimizes the APK for installation on various Android devices. Use the zipalign tool (also part of the Android SDK):
zipalign -v 4 my-app-signed.apk my-app-aligned.apk

This creates a final, optimized APK (my-app-aligned.apk).

Important Notes:

  • Keep your keystore safe! Losing it means you'll lose the ability to update your app.
  • Use a strong password.
  • Never share your keystore with anyone.
  • Use a version control system to safely manage your keystore (like Git, but store it securely outside your primary repository).

Simple Answer:

To ensure your Android APK's authenticity, generate a keystore using keytool, then sign your APK using jarsigner and optionally align it using zipalign from the Android SDK tools.
