Error build Android (Defold 1.2.172)

gritsaenkosergeia · August 25, 2020, 9:11am

Hi! I used the new version of Defold to open my old project, it has no dependencies. I get this error when building for Android:

Unknown source:
contextResource cannot be null.

If you make an Android bundle with bob.jar directly it might give you a more specific error printed to the console.

I vaguely remember this error happening once in one of our projects but never posted about it. Sometimes to find weird problems like this we make a copy of a project and strip parts out, then try to bundle again, and repeat until it works to narrow down the problem.

It originates from this line of code:

github.com

defold/defold/blob/dev/com.dynamo.cr/com.dynamo.cr.bob/src/com/dynamo/bob/MultipleCompileException.java#L88


    Info info = new Info();
    info.severity = severity;
    info.resource = resource;
    info.lineNumber = lineNumber;
    info.message = message;
    this.issues.add(info);
}


public void attachLog(IResource contextResource, String rawLog) {
    if (contextResource == null) {
        throw new IllegalArgumentException("contextResource cannot be null.");
    }


    if (rawLog == null) {
        throw new IllegalArgumentException("rawLog cannot be null.");
    }


    this.contextResource = contextResource;
    this.rawLog = rawLog;
}

From here:

github.com

defold/defold/blob/dev/com.dynamo.cr/com.dynamo.cr.bob/src/com/dynamo/bob/bundle/BundleHelper.java#L1145


            if (contextResource == null && issueResource != null) {
                contextResource = issueResource;
            }
        }


        // If we do not yet have a context resource - fall back on an ext.manifest (possibly the wrong one!)
        if (contextResource == null) {
            contextResource = extManifestResource;
        }


        exception.attachLog(contextResource, buildError);
        throw exception;
    } catch (IOException ioe) {
        buildError = "<failed reading log>";
    } catch (CompileExceptionError ioe) {
        buildError = String.format("'%s' could not be built. Sdk version: '%s'\nLog: '%s'", platform, sdkVersion, buildError);
        throw new CompileExceptionError(buildError, e.getCause());
    }
}
buildError = String.format("'%s' could not be built. Sdk version: '%s'\nLog: '%s'", platform, sdkVersion, buildError);
throw new CompileExceptionError(buildError, e.getCause());

Are you using an app manifest to reduce the engine size?

gritsaenkosergeia · August 25, 2020, 12:24pm

Thank you for your answer, Yes I use app manifest, but it doesn’t seem to be the case. I still get this error. Maybe I should create a new project and add all the resources again

britzl · August 25, 2020, 12:41pm

You could try that but I’d like to understand why you got the error in the first place. If you are able to share the project with me (bjorn@defold.se) I can take a look as well.

gritsaenkosergeia · August 25, 2020, 1:02pm

I sent the project to you. Tell me if you find a problem, thank you

Just to add to the case, i’m having the same problem bundling the extension https://github.com/defold/extension-admob/ for android.

Mathias_Westerdahl · September 14, 2020, 9:44am

Do you have any more info about your troubles? Any build logs or errors?

gritsaenkosergeia · September 14, 2020, 9:49am

Yes, the admob extension is to blame. Its owner asks you to pay in patreon. I just removed this extension and now use unity ads, which is much better than admob. Now everything is fine

Mathias_Westerdahl · September 14, 2020, 10:02am

Note that this was the defold extension, which admittedly hasn’t gotten much love or attention. However, we’d still like to be able to build it properly.

Ceonello · September 14, 2020, 4:47pm

Hi Mathias, i just downloaded the project from https://github.com/defold/extension-admob/ and tried building it targeting Android Apk.
The building process stop wit this is error “contextResource cannot be null.”
If i can help in other ways just tell me.

Thank you

As suggested in a post of this thread, i tried building the project with bob.jar from command line, this is the exception stacktrace:

So is there a fix for this or do we just have to pay this guy so I can update my app. Aside from changing to Unity.

britzl · September 23, 2020, 3:38pm

The extension discussed in this thread is ancient and has never really been used in production. It was one of the first extensions ever created to test the feature. @sergey.lerg created a proper AdMob extension a long time ago. At first it was rev-share and recently change to paid access. The old rev-share version is still available:

Another alternative is to use Enhance to inject AdMob into your APK: https://defold.com/assets/enhance/

Or switch to UnityAds: https://defold.com/assets/defvideoads/

A final option would be to fix up the extension discussed in this thread, but that’s probably the most difficult if you haven’t worked with extensions before.
