Question: Your Version vs Android Version?

[0pLuS0]

Hello

Sorry for any ignorance on my part, but could you please explain what differences there are between your version of signapk.jar and the Android version?

This links downloads it;

I noticed that Google signapk.apk is 2MB in size, quite a difference, and I opened it up, of course a lot more going on, but can't I understand the difference still between them, if just to sign an apk?

Also I'm assuming to sign a apk all I need is signapk.jar, and then this command?

java -jar signapk.jar certificate.pem key.pk8 framework-res.apk test.apk

I used your signapk.jar to test this on framework-res.apk, which wasn't booting up, and then someone told me I might need to sign it, and so I did, and now it boots...

Thanks

Android signapk is updated and uses bouncycastle instead of sun classes, that's why it big.

another thing is this uses testkeys that are embedded in jar file itself, so you dont need them.

Third thing is that it can be used to sign with ONLY testkeys, no option to specify PRIVATE keys or other google keys.
