Generating a signed APK
To generate the signed APK, navigate to Build | Generate Signed APK. Select the app module and click on the Next button. In the dialog to generate the signed APK, we are asked for a certificate. The APK is signed by this certificate, which indicates that it belongs to us.
If this is our first application, we might not have any certificates. Click on the Create new... button to open the New Key Store dialog. Now, fill in the following information:
Key store path: This is the path in your system to create the key store. The key store is a file with the
.jksextension, for example,release_keystore.jks.Password: This is the key store password. You have to confirm it.
Alias: This is the alias for your certificate and is a pair of public and private keys. Let's name it
releasekey.Password: This is the certificate password. You have to confirm it.
Validity (years): This is the certificate that will be valid until the validity date. A value of 25 years or more is recommended...
