Android APK program Signature

[Preface]
We usually develop Android applicationsProgramGenerally, the integrated development environment of eclipse is used, so the generated APK has the signature permission for the debug version. However, if we want to release an application, if you want to run on a real machine, you need to sign it.

[Tools]
Keytool and jarsigner in the Java Development Environment. Note that the Environment path is configured. The following prompt is displayed after you enter the command:
