APK Signing Failed! Unable to determine signature algorithm.

Hi,
I wanted to compile an android project (in 3.5.0b6) started in unity 3.4 and updated to 3.5.0b6, but it fails at signing the APK so i can't upload an updated version to the android market.
It worked well in 3.4.

Code (csharp):

1. Error building Player: UnityException: APK Signing Failed!
2. Unable to determine signature algorithm.  See the Console for details.

Error in file: at line -1


theres also a message about data entered in the Key for the game in the console followed by:

Code (csharp):

1. UnityEngine.Debug:LogError(Object)
2. PostProcessAndroidPlayer:GetSigAlgo()
3. PostProcessAndroidPlayer:SignAndroidPackage(String)
4. PostProcessAndroidPlayer:PostProcess(BuildTarget, String, String, String, String, String, String, BuildOptions)
5. UnityEditor.HostView:OnGUI()

Error in file: .../Runtime/ExportGenerated/Editor/UnityEngineDebug.cpp at line 39


it also throws another error message first:

Code (csharp):

1. !IsDirectoryCreated(targetFolder)
2. UnityEditor.HostView:OnGUI()

Error in file: .../Editor/Src/BuildPipeline/BuildTargetPlatformSpecific.cpp at line 413


Is anyone else experiencing this problem too and is there a workaround/solution? Or do i have to wait until the unity team fixed it and releases an update?
I'm using unity pro with android pro on win 7 32bit and 64bit. (in case it matters)

 

I'm getting this error:

!IsDirectoryCreated(targetFolder)
UnityEditor.HostView:OnGUI()

Error in file: .../Editor/Src/BuildPipeline/BuildTargetPlatformSpecific.cpp at line 413

but none of the other ones. The above error has not prevented me from publishing in the Android Market, but I'd still like to know what the error means.

 

Downloaded installed 3.5.0f1 and still experience this problem.

No one else having this problem? And there's no known solution to it?

 

I am facing the same problem as Fuzzy does."APK Signing Failed! Unable to determine signature algorithm."
I spent a day on this matter but got no luck.
My project works fine ( can be exported , signed and uploaded to android market ) in Unity 3.4. But fail to export in Unity 3.5.0f1.

 

I had the same problem and it seems like it keeps loosing the password for the keygen, othertimes I just close the editor reopen it and it seems to solve it most of the time.

 

Re-opening the editor did not work for me, at lest the maybe 10 times i've tried it.

So is there still no solution around? And is this really such a rare problem as it seems, since there are barely any repsonses about others having the same problem here.

 

I got the same problem, but only on Windows
Doing the signing on OSX works flawlessly ... This might al come down to an incompatible Java Version installed or similar

 

Awesome!
I have to thank you!

 

I am still having this issue with the release version of 3.5.

 

Hi Erique,

I am still experiencing the issue of APK signing failing when I try to build and sign my app in 3.5 release.

In a previous reply in this thread, you stated to have identified the problem and that it would be fixed in 3.5 release version.

Perhaps it is my setup, but I have tried 3 different versions of JDK (both 32-bit and 64-bit). I'm not sure what else it could be. I have tried uninstalling and reinstalling Unity, and updated the Android SDK.

This is a critical issue, as I can't release my apps to the Android Market at the moment.

Would really appreciate for this to be looked into.

 

bump for this critical issue

 

Bingo that's it!

My CLASSPATH environment variable had been set by another software (OpenNI in my case). For anyone else having this problem, rename or remove the CLASSPATH environment variable.

Thanks a lot, issue resolved.

 

Same problem here. I tried un-installing all java software (jre, jdk, etc), removed all registry entries, paths, etc. Then re-installed the jre and jdk. Same problem. Reset the classpath to just ".;", same problem. Set the classpath to ".;F:\JDK\bin", same problem. Removing the classpath environment variable entirely doesn't solve the problem either. All methods tried after a reboot.
This is serious!

 

hey guys , im facing the same prob. i have downloaded the Unity for Android 3.5 version and also have included Vuforia plugin to add some AR. I tried building the same app and while building im getting this error.

I tried rebooting the system, reloading the Unity ,i even changed my t shirt .Nothing worked
m kinda frustrated.any suggestions would help.Thank you !!

 

Same errors here, I'm trying to fix this and I'm getting a variety of "APK Signing Failed! Unable to determine signature algorithm." or
"jarsigner: unable to read password .... APK Signing Failed!" and others.

This is quite unnacceptable. Anyone have more possible solutions to this?
Thanks a bunch

ps: that's in 3.5.0f5

 

I had the same problem plaguing me for a while, and managed to fix it by upgrading OSX Unity from 3.5.0f1 to 3.5.0f5.

 

I'm on PC, maybe I'll try reinstalling Unity, eh who knows

 

I reinstalled Unity 3.4.0f5 (latest version) and it still doesn't work.

 

Looks like this problem is back in the newest version of unity

 

I fixed this issue by uninstalling everything java, the jdk, all the java envrionement variables and reinstalling jdk 6.x, hope it helps

 

Having this issue too.

 

Did you try what I said? In the last post? I also found that with my new computer, which is a 64bit, I had installed jdk 64bit but you need to install the 32bit version otherwise there are problems.
