    Just to say thank you guys (gamestudio > perfect step by step), and suggest that this thread should be a tutorial on the Android Publishing page of Unity.com

    That helped a lot!

    I think I am facing the same problem you guys did but I can't get past to it. I am on OS/X, using Unity 3.5.2 and whenever I try to create "create new key" after entering the info and confirming, I get this error:

    And then the alias is not shown on the alias drop down (only Unsigned (debug) is shown actually)

    Now I checked my Java stuff here and it seems to be running ok, my version is "1.6.0_33" (according to java -version)

    I've also runned the same command printed on Unity output via terminal and it seems to work, but when I select the "use existing keystone" option using the created keystore it happens the same thing as before...nothing is shown on the alias drop down menu.

    Then I created this keystore on a Windows7 command prompt and try to load it back on Unity but... nothing changed...

    Updated my Unity to the latest version (3.5.5f3) and gave another shot...still the same problem...

    Is there something else I could/should do??? (besides what I am constantly thinking these days -> abandoning Unity)

    I get the same fault, is there any solution to this.
    Using the debug signing works no problem but my own generated key wont let the application install.

    EDIT:

    I uninstalled jdk-7u3-windows-x64 and then installed jdk-6u34-windows-i586 and it all works 100% now.

    Ok, I get it.
    I follow the gamestudio's tutorial.

    But I have other problem now.
    I insert the key. Is all ok, but when I try to install in my device, it say: "Application is not installed".

    I try in 2 differents devices, and it show me the same.

    I test to build without the key and I installed, but I need with the key.

    Can anyone help me, please?

    Hi everyone.

    I've just done battle with the infamous JDK 1.7 signing issue and have gone back to the JDK 1.6. When I create a new keystore and key, I can build,sign, and install my app just fine. I can't, however, use the old key and keystore I previously made.

    First of all, does that make sense that the key I created (albeit with the 1.7 version of the JDK) won't work anymore? I'll admit, I'm completely new to the whole signing thing, but I thought the important part was the actual signing process that happens after the build.

    Second of all, if I'm not mistaken, when I try to upload the new apk to the Google Play store, it won't let me upgrade the existing bad version because it will have a different key. Is there any way around that? I'd rather use the existing listing and upgrade rather than have to disable it and have old garbage laying around. Any hints?

    Thanks,
    David

    What I did was delete the non working JDK 1.7 generated keystore and created a new one with JDK 1.6 using the exact same details passwords and alias and had no problems.

    I think it is an issue with the generation of the keystore itself that is the problem with 1.7

    I also use the JDK 'keytool.exe' program from the windows command line to generate my keystore then just use that keystore in unity.

    I am using Unity3d 3.5.4f1 on Mac OS lion 10.7.5
    After following all the step of creating keystore inside unity3d editor, when I click on create key button, nothing is happening. The Keystore window remains same with no error.

    It helps to simply sanity check your APK to confirm Unity is actually signing your app.

    Your keystone settings will be reflected in the output plus the expiration date. You should see any Debug CERT messages in there...

    Note if you then apply Android Market License aka Google Play's Public Key (provide by google) you may also see this error: jarsigner: java.util.zip.ZipException: error in opening zip file. Which will be ok. You would leave this field blank when signing your app for Barnes and Noble Nook.

    I think I've signed properly through Unity and yet when I attempt to upload my apk to google play it throws this error:

    Upload failed
    We could not save your changes. Please try again.


    I cant check if i've signed properly through jarsigner or keytool because the exe in this path just disappears:
    C:\Program Files (x86)\Java\jdk1.7.0_09\bin

    I've tried adding the path to the environment variables and no luck .

    What am I missing?

    I successfully created the key/keystore inside of unity 3.5.6. One note is that i believe you have to make the alias name the same as the keystore file name itself (without '.keystore' of course. :)

    Thanks for all the help. :p

    We had the same problem with Unity 3.5.5 , Windows 7 64-bit, Java 1.7 64bit .

    gamestudios Tutorial help a lot - so better use Java 1.6 32bit.

    One remark. I think it's possible to see that the key is bad, all our old keystores had some strange code at the
    end (Extensions: ...........)
    So it's good to have a look at the keystores with:
    keytool -list -v -keystore name_of_the_keystore.Keystore
    So you don't have to upload bad version to Play Store, to test it.

    (If you can't run that command you should set the system varriables like gamstudio explained it.)

    Hi, I just wanted to let you know that for 3.5.7 and 4.0 we did a major cleanup in regards to how we handle apk signing. Hopefully this will solve any problems previously related to different versions of java and/or different signing algorithms. The fix should also provide you with more detailed error messages as to what the problem is when the apk fails the signing process.

    Anyone have a solution for this? I did see the answer at http://stackoverflow.com/questions/4322367/i-lost-my-keystore-file but I would like more explanation. If I remember all the fields in the "Create a new key" dialog, shouldn't I be able to generate the same key and update my application? What other variables does key generation take into account to make it unique? I'm new to this; thanks.

    Unfortunately you can't. The certificate and the key used for signing is unique. I haven't looked at the implementation but I'm pretty sure 'secure random' is part of the equation. So, make sure you always backup the keystore!

    What is the latest version of the jdk we can use to make keystone? I am trying it with 1.7.0 v11 32 bit and the Unity Editor is telling me to go take a hike.

    Using Unity Pro 4.0.1 (With Unity Pro Android)

    Thanks.

    [EDIT]
    Fixed all my problems with JDK Java SE 6 Update 41 32 bit version.

    Question:

    If Unity can create new keystore and alias key, why we still need to create and make use of keytool and jarsigner?( are there some reasons behind?)
    And where is the LVL? I am a bit messy with it now, what is the proper way to publish a apk in google play, PLEASE give a hand!!!

    All applications are automatically signed by the android build tool used by Unity. If you don't provide a key the application will be signed with a debug key provided by the tool. However, this debug key will not be valid for publishing.

    That has nothing to do with the signature. In the Build Settings window there is a checkbox "Development Build", make sure that is unchecked before doing your final release build.

    You have to select where to save your keystore. Hit "Browse Keystore" and select a location. After that "Create a new Key" should then be enabled for that keystore.

    I believe it's still there, as long as you've entered all the information in step (2) (using the correct/matching passwords)?

    Hey! Sorry to dig an old post like this, but is anyone else having this issue of play store complaining the AAB is in debug mode even when it's NOT in debug mode?

    This is my build settings:
    upload_2021-5-25_23-47-42.png

    Publishing settings:
    upload_2021-5-25_23-48-5.png

    My other settings:
    upload_2021-5-25_23-48-53.png

    I have just created a new app in play console and right now I'm trying to upload the first version of the game to open test. I just don't stop getting this error...

    I created my key, registered my password, alias and so on... I have already published a game before to play store and I didn't have any problem... but right now I'm stuck in this for days trying, trying, trying....

    Anyone? Any light?

    (Unity 2020.3.6f here)

    [EDIT] -----------------------------------------------------------------------------

    I figured it out!
    I checked my AndroidManifest.xml in "Assets/Plugins/Android/" and I found this:
    Code (CSharp):
    1. <application android:theme="@style/UnityThemeSelector" android:icon="@drawable/app_icon" android:label="@string/app_name" android:debuggable="true">
    I've just set this android:debuggable="true" to false. And that's it!
