Unity 3.5 "Compile NDK" deletes " lib-ouya-ndk.so " and other .unitypackage files

Ameon · January 2013

After hitting "compile NDK", we lose some files and get the following message:

console message:
A meta data file (.meta) exists but its asset 'Assets/Plugins/Android/libs/armeabi/lib-ouya-ndk.so' can't be found. When moving or deleting files outside of Unity, please ensure that the corresponding .meta file is moved or deleted along with it.
UnityEditor.AssetDatabase:Refresh()
OuyaPanel:Update() (at Assets/Ouya/SDK/Editor/OuyaPanel.cs:507)
UnityEditor.EditorApplication:Internal_CallUpdateFunctions()

Has anybody encountered this?

I haven't had that problem, but have you made sure that you have the NDK ( it's not grayed out ) installed and that the OuyaPanel is pointed to it?

I would double check that first.

additional note: at first, i didn't even have the NDK and didn't realize it. You can get it here:

You can ignore the meta file message. Unity is going to automatically recreate it. And since gameobjects don't reference that compiled file, the meta file can be ignored.

Yes tgraupmann you are right, it builds fine after files delete.

hi there, i'm having a similar problem.

first, when i import the Core package from scratch, all the fields in the Ouya Panel are filled in properly. (i've also updated the Build Identifier and commented out certain bits of code according to the required-steps). so far so good.

as soon as i hit the Compile button from the Ouya Panel Window, these 3 files get deleted:

\Plugins\Android\libs\armeabi\lib-ouya-ndk.so

\Plugins\Android\OuyaUnityPlugin.jar

\Plugins\Android\OuyaUnityApplication.jar

when that happens, the "OUYA/Plugin Jar" and "OUYA NDK Lib" fields in the 2 panels go grey because the link to those file are no longer there.

i noticed that for the OuyaUnityPlugin and OuyaUnityApplication files, this function is specifically deleting them: OuyaMenuAdmin::BuildApplicationJar(). if i try to compile again, i get an error because OuyaUnityPlugin is missing.

i'm using Unity 4.1.5f1

JDK 1.6, 32-bit

Android set to 4.1, Level 16

any help would be appreciated. thanks.

Make sure you sync your bundle id. Sure the process deletes the files it is about to create. And if there's a compile error, it will fail to create them. Do you have any errors in your log?

hi Tim, thanks for the quick reply.

i've definitely hit the Sync Bundle ID before doing any of this. here's what i've found:

- when i Compile Plugin from the Panel, it deletes the OuyaUnityPlugin.jar file and never re-creates it.

- the Console produces 12 lines of text but there are no errors reported.

- when i Compile Java from the Panel, it deletes the OuyaUnityApplication.jar file and never re-creates it.

- the Console produces 16 lines of text but there are no errors reported.

i was able to find a "fix" to the issue where the lib-ouya-ndk.so was being deleted and not re-created. someone wrote: "For now, as a workaround, move your android-ndk-r8d folder to C.".

hopefully someone can shed some light on why the other 2 files get deleted but not re-created.

thanks.

Oh yeah the NDK has to be at your root. The build scripts for NDK don't tolerate spaces.

hi again, i still need to figure out why OuyaUnityPlugin.jar doesn't get re-created when i select "Compile Plugin".

looking at the BuildApplicationJar() function, it seems to:

1) create a temporary folder called \Android\Classes

2) create the OuyaUnityPlugin,jar file within that Classes folder

3) delete the original \Android\OuyaUnityPlugin,jar file

4) move the newly created file from \Android\Classes\ to \Android\

5) finally, delete the \Android\Classes folder

this all makes sense but my problem seems to be with step (2); it never creates the file i need. if i comment out the code that eventually deletes the Classes folder, i noticed that it didn't actually create any files within it.

the OuyaPanel::RunProcess() function (which seems to be where the file creation is being handled) isn't reporting any errors.

getting this plugin file created is the last step in world domination so let me know if there's anything else i can do make it work.

i'm using Unity 4.1.5f1

JDK 1.6, 32-bit

Android set to 4.1, Level 16

thanks.

SOLVED. the Ouya Plugin and Application JAR files now get created after i upgraded to Java 1.7 (JDK 1.7.0_25).

tgraupmann · July 2013

I was thinking other things can get messed up if you have things in your path.

Like if you have two versions of Java in your path, it might make the compiling tricky.

I have the same problem when cygwin is in my path and I try to compile ndk.

JDK 1.7 probably works on the latest Unity 4.X version. I doubt it works for the 3.X folks. But apparently there are only 5% still on 3.X...

Howdy, Stranger!
