Android Application APK signing?

I would like to know about Android application signing.

IFAIK, blackberry and iphone application must be signed to work on the real device. For the Android, does app开发者_Go百科lication need to sign ?

If so, how to sign the application ?

Please advice. guys.

Thanks in advance.

If you are using the Eclipse plugin.

Right click on the project > Android Tools > Export Signed Application Package

Follow the instructions for creating a .keystore file and you're sorted!

There's a guide to signing Android applications on the developer website: http://developer.android.com/guide/publishing/app-signing.html

To answer your immediate concern: you don't need a real device to sign an application. You sign during the build process, so it can be done on any computer with the correct software (which is all free). The easiest way to build a signed application is to just use Eclipse's ADT plugin, which has an "export signed application" feature.

As @Laurence Dawson mentioned one way to do this is just by opening your project in eclipse then

Right click on the project > Android Tools > Export Signed Application Package

BUT you MUST create a Keystore prior to do this, this is really easy and simple the option will appear after you select "Export Signed Application Package" from right click options, it will ask you to "sign" your APK (in order to Beta/Alpha/Production publish) this process is done simply by creating this Keystore, once its created just select this new keystore (it will appear right in the options of "Export Signed Application Package") and voila! then it will just ask you for enter the path where to upload your signed APK ready for google developer website!
