"Debug certificate expired' error in Eclipse Android plugins


I am using Eclipse Android plugins to build a project, but I am getting this error in the console window:




[2010-02-03 10:31:14 - androidVNC]Error generating final archive:



Debug certificate expired on 1/30/10 2:35 PM!




How do I fix it?

  1. Delete your debug certificate under ~/.android/debug.keystore on Linux and Mac OS X; the directory is something like %USERPROFILE%/.androidon Windows.

    The Eclipse plugin should then generate a new certificate when you next try to build a debug package. You may need to clean and then build to generate the certificate.

  2. Upon installation, the Android SDK generates a "debug" signing certificate for you in a keystore called debug.keystore. The Eclipse plug-in uses this certificate to sign each application build that is generated.

    Unfortunately a debug certificate is only valid for 365 days. To generate a new one you must delete the existing debug.keystore file. Its location is platform dependent - you can find it in Preferences - Android - Build - Default debug keystore.

  3. It's a pain to have to delete all your development .apk files, because the new certificate doesn't match so you can't upgrade them in all your AVDs. You have to get another development MAP-API key as well. There's another solution.

    You can create your own debug certificate in debug.keystore with whatever expiration you want. Do this in the .android folder under your HOME directory:

    keytool -genkey -v -keystore debug.keystore -alias androiddebugkey -storepass android -keypass android -keyalg RSA -validity 14000

    ADT sets the first and last name on the certificate as "Android Debug", the organizational unit as "Android" and the two-letter country code as "US". You can leave the organization, city, and state values as "Unknown". This example uses a validity of 14000 days. You can use whatever value you like.

  4. On Vista, this worked:


    DOS: del c:\user\dad\.android\debug.keystore
    ECLIPSE: In Project, Clean the project. Close Eclipse. Re-open Eclipse.
    ECLIPSE: Start the Emulator. Remove the Application from the emulator.


    You are good to go.

    I was pretty worried when I say that error, but I fixed it from reading here and playing around for 10 minutes.

  5. WINDOWS


    Delete: debug.keystore
    located in
    C:\Documents and Settings\[user].android

    Restart Eclipse and automatically you will have another keystore


    MAC


    Delete your keystore located in ~/.android/debug.keystore then restart Eclipse.

  6. In Windows 7 it is at the path

    C:\Users\[username]\.android



    goto this path and remove debug.keystore
    clean and build your project.

  7. If certificate expires in the middle of project debugging you must do manual uninstall:

    Please execute 'adb uninstall <package_name>' in a shell.

  8. On Ubuntu, this worked:

    I went to home/username/.android and I renamed keystore.debug to keystoreold.debug. I then closed Eclipse, started Eclipse, and SDK created new certificate keystore.debug in that folder.

    You then have to uninstall/reinstall apps you installed via USB Debugging or an unsigned APK ("unsigned" APK = signed with debug certificate).

  9. I had this problem couple of weeks ago. I first tried the troubleshooting on the Android developer site, but without luck. After that I reinstalled the Android SDK, which solved my problem.

  10. On a Mac, open the console (current user's directory should open), cd ".android" ("ls" to validate debug.keystore is there). Finally "rm debug.keystore" to remove the file.

  11. H-m-m-m. Interesting how so many people have had slightly different experiences with this. I remember the days when this was considered a sign that the software was not ready for release, and the team would actually fix it BEFORE users started seeing these problems:(

    My own experience was just a little different. I had already tried Project>Clean, but still got the same build failure. Then I deleted the debug.keystore (under .android) just as the first answer said. Still got the same problem. Then I did a clean again, and wonder of wonders, it worked!

    Now don't get me wrong, I am glad that I got it working thanks to the hints in this thread. But clearly clean isn't working right, and how did it find an expired key after I deleted the keystore??? Clearly something is wrong with Eclipse or the ADT -- not so sure which.

  12. The Android SDK generates a "debug" signing certificate for you in a keystore called debug.keystore.The Eclipse plug-in uses this certificate to sign each application build that is generated.

    Unfortunately a debug certificate is only valid for 365 days. To generate a new one, you must delete the existing debug.keystore file. Its location is platform dependent - you can find it in Preferences -> Android -> Build -> *Default debug keystore.

    If you are using Windows, follow the steps below.

    DOS: del c:\user\dad.android\debug.keystore

    Eclipse: In Project, Clean the project. Close Eclipse. Re-open Eclipse.

    Eclipse: Start the Emulator. Remove the Application from the emulator.

    If you are using Linux or Mac, follow the steps below.

    Manually delete debug.keystore from the .android folder.

    You can find the .android folder like this: home/username/.android

    Note: the default .android file will be hidden.

    So click on the places menu. Under select home folder. Under click on view, under click show hidden files and then the .android folder will be visible.

    Delete debug.keystore from the .android folder.

    Then clean your project. Now Android will generate a new .android folder file.

  13. 1) It would be nice to be warned this fun is coming when I start a project.

    2) Thanks to Mortensen and Kumar for the link 'Click For Full Solution'. The first suggestion there worked. And I'd tried editing the start/end dates in the keystore file using UltraEdit. Nothin.

    3) AND finally, can some old hand at the Eclipse IDE (or is the an Android issue) please tell me what purpose having your project unable to be rebuilt if you come back to it 366 days later possibly serves?

  14. Delete following file and clean build in Eclipse:

    Linux and Mac OS X
    ~/.android/debug.keystore on
    Windows:
    %USERPROFILE%/.android
