I am trying to export my app and the first problem I'm running into is finding the correct keystore. This is the file I selected: C:UsersJohnandroid-sdkssourcesandroid-14androidsecurityKeyStore.java And I use the password of: android When I click next it say "invalid keystore format" and I am not able to select an alias. How do you fix this? Will it work if I create a new keystore and key?

Im using eclipse and its a v1.4 app.

Hi MadMaxwell, Yep, you can create new keystores. Just make sure you use the same release keystore for any updates to your app. Here is a doc with step-by-step instructions to help you along: http://www.buzztouch.com/resources/Signing_Android_Apps_v1.0.pdf Mark

When Im creating a new key, what am I suppose to input for Validity(Years)? Does this mean how long the key is good for?

Yes..that means how many years it's good for. Android recommends a validity period of 25 years or more. Mark

I used the file above for my new keystore location, am I suppose to you something else because after I created a new key it said that the keystore was still invalid. Thanks for all the help Mark.

I'm not sure I follow. If you create a new release.keystore or debug.keystore, and gave it the appropriate passwords and alias', then you should be able sign your apps with no issues. You can actually even create a new keystore during the Export process for your app...just follow the wizard. Have you tried that? Mark

Yea, I'm using the wizard for the export process. The first page gives me the option to use existing keystore or create a new keystore. When I select create a new keystore the only thing that changes is that it asks me to confirm the password. It wont let me click next because it says that the file already exits...

I have a KeyStore Guide thay could help you. www.myskylla.wordpress.com Fred

OK, this is how it should go: * Right-click your project, hit Export... * Select Export Android Application, hit Next * Your current project should be listed there, so hit Next * Select the Create New Keystore radio button * Browse to where you want to save the keystore, and give it a name like madmaxwell_release.keystore. Don't select the one (release.keystore) that already exits. * Provide a password, and verify. Hit Next. * Enter a keystore alias, like madmaxrelease. Put in your password twice, and a validity > 25yrs. Fill in one of the remaining fields (Name is a good one). * Hit Next * Select the destination and filename for your apk file. * Hit Finish. That's it! Let me know how it works out! Mark *

I think I found the problem. * Browse to where you want to save the keystore, and give it a name like madmaxwell_release.keystore. Don't select the one (release.keystore) that already exits. I was selecting an existing file instead of create a new folder to save it to. I'll let you know what happens.

It works! Thanks for everything.

Awesomeness! Make sure you post the URL to your app when you publish it so we can all take a look! Mark

If you do a google search of "keytool" there is an add-on for eclipse that will help you with building your keystores. I have it on my eclipse indigo and it works great

Is this what you're talking about : http://keytool.sourceforge.net/ Looks pretty cool!

The tool is not necessary for creating the keystore, simple process, very useful for the Google Maps API key. Fred

Yes GoNorthWest. And though Fred is telling the truth, you do not "NEED" keytool, it is a neat add-on that is helpful to have... now if we only had an add-on that integrated advertising. Wish i was geeky enough to write raw code, that would be an add-on or plug in that ALL of us could use! :-)
