Tutorial on Signing your apk for publishing!

[Destroythenseek]

Hey Guys,
I had a really really really hard time figuring this out so here is exactly how to do it for those of you who need/want it.

First of all,
jarsigner and keytool are .exe files that help create your "signed" application for release to the market to prevent fraud.

1.
Make a folder somewhere called "keytools" and make a folder in that called "keys"

2.
If you're using Eclipse, in Package Exp window... right click on your project -> Android Tools -> Exports Unsigned Application Package ... Save in keytools
"filename.apk" or something.

3. Check
"C:\Program Files\Java\jdk1.6.0_12\bin" for jarsigner and keytools..
... or whatever jdk version you have

If you DONT have it install the following .. https://cds.sun.com/is-bin/INTERSHOP...-CDS_Developer

4. open cmd.exe,

5. cd your way to where you have your keytools folder...
I had to do.. cd desktop, cd g1, cd keytools to get to C:\Users\Anton\Desktop\G1\keytools\

In this directory is you apk file which we will manipulate.

type the following now (or something similar to my example)...
C:\"Program Files"\Java\jdk1.6.0_12\bin\keytool -genkey -alias donate.keystore -keyalg RSA -validity 20000 -keystore keys/donate.keystore

Then you will have be presented with:
Enter keystore password: (type in a password you will use)
Re-enter new password: (type in same password here)
What is your first and last name? Anton
What is the name of your Organization unit? (You dont have to type anything really)
What is the name of your city or locality?
What is the name of your state or providence?
what is the two-letter country code for this unit? US
is CN=Anton C=US correct?
[no]: yes (type yes there)
Enter key password for <donate.keystore>
<RETURN if same as keystore password>: (push enter)

6.

type the following now (or something similar to my example)...
C:\"Program Files"\Java\jdk1.6.0_12\bin\jarsigner -verbose -keystore key/donate.keystore -signedjar Donate_signed.apk Donate.apk donate.keystore

Enter Passphase for keystore: (your password you made earlier)
adding: META-INF/MINFEST.MF ....
.......
.....
...Signing: classes.dex

and you're all set! you signed your Doante_signed.apk file or whatever you wanted to create!
Congratulations.
NOW STOP BEING FRUSTRATED LIKE I WAS FOR HOURS!

Thanks a lot!
Great info!
This is exectly what I am looking for.
Do you have such a great topic regarding application updating?

[dackyD]

Sorry for resurecting this post, but does signing get rid of the "Install Blocked" message when you are installing your signed application?

I thought it does, so how do we get rid of this message?

Thanks

This dont work for me
I have 2 sets of java folders, and tried all with this but it doesnt work

C:\android\keytools>C:\Program Files (x86)\Java\jdk1.6.0_17\bin\keytool -genkey
-v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -validity 100
00
'C:\Program' is not recognized as an internal or external command,
operable program or batch file.

C:\android\keytools>

and this

C:\android\keytools\keys>C:\Program Files\Java\jre6\bin\keytool -genkey -alias d
onate.keystore -keyalg RSA -validity 20000 -keystore keys/donate.keystore
'C:\Program' is not recognized as an internal or external command,
operable program or batch file.

am new to android but my java setup is fine...a little help

britishgoose - I haven't successfully completed this via these instructions yet but the problem you are getting originates from the space character in your command. In your command you need to add quotations around Program Files. C:\Program Files (x86)\Java should be C:\"Program Files (x86)"\Java

Hope this solves your problem.
