My understanding of the signature of the APK file in Android (1)

To publishProgramDevelopers need to use their own digital certificates to sign the APK package. There are two methods.

1. Use JDK and keytool (used to generate digital certificates) and jarsigner (used to sign digital certificates) in the command line to sign the APK package.

2. Use the ADT export wizard (wizard) for signature (if there is no digital certificate, you may need to generate a digital certificate ).

Previously, I wrote a blog about signature using method 1. However, using method 2 makes it easier for us to complete this process. In eclipse, right-click the application project and choose Android tools, as shown in:

 

 

Then, you can perform operations step by step, which is exactly the same as the operations under the command line. I will not repeat it here, and I will explain a lot about this on the Internet (I agree with it more often in method 2 ).
