RoboGuice 3.0 NoClassDefFoundError: AnnotationDatabaseImpl

Question

For some reason the RoboBlender does not generate the annotation database. My build.gradle has the following dependencies:

dependencies {
    provided 'org.roboguice:roboblender:3.0'
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'org.roboguice:roboguice:3.0'
}

Answer 1

This is not a final solution, but it can help you. I don't know why, but RoboGuice 3.0 and 3.0.1 throws this exception. What you have to do is disable annotations for databases in your MainActivity as follows:

static {
    RoboGuice.setUseAnnotationDatabases(false);
}

I hope this help

Answer 2

Ok, so it seems that since I didn't have any injection in the main class MainActivity it didn't trigger the annotation processing of the inner AsyncTask. Therefore no annotation database was created.

Moreover, it seems that injection in anonymous inner classes is not supported. So the AsyncTask needs to be a proper class (it can still be inside the MainActivity).

I haven't figured out yet how to tell RoboGuice to inspect the inner classes even though the outer one does not have injections.

were you able to figure this out? – Spinning

Answer 3

What does the rest of your project structure look like?

Specifically, have you read the RoboBlender wiki

Later versions of Android Studio will, by default, generate a project that falls into the Configuring RoboBlender for a large application using libraries-category.

Fix below does the following:

1. Rearrange dependencies in build.gradle
2. Supplies pointer to GuiceModule in project
3. Rudimentary module for your project

I added the compiler arguments and the meta-data in android manifest. You can find the full project at: github.com/jush/RoboGuice3Test The error is still: "Didn't find class "org.jush.roboguice3test.AnnotationDatabaseImpl" on path: /data/app/org.jush.roboguice3test-1.apk" – Neologism

AndroidManifest.xml is missing something like ``` <meta-data android:name="roboguice.modules" android:value="org.jush.roboguice3test.GuiceModule"/>``` and then your in your project, create that module as well. It could very well be empty. – Beatnik

thanks for the suggestion but it didn't help even though I added it: github.com/jush/RoboGuice3Test/commit/… – Neologism

I tried as you suggested, re-order dependencies and added module constructor with Application parameter and still same error. – Neologism

Answer 4

What did you have to do that it did trigger the annotation processing? My main activity has injections. The maina activity inherits from an abstract activity which has as well injections. That abstract activity inherits from RoboActivity.

When i set the roboguice.annotations.packages to roboguice the NoClassFound exception isn't thrown anymore, but i get a NullPointer Exception for the first inject-Object that I wanna use.

I use eclipse to start the app.

When I disable RoboBlender (RoboGuice.setUseAnnotationDatabases(false);) injection works.

Pierson

If your activity inherits from RoboActivity then it's a different problem from the one I had. Moreover, you say that if you disable the annotation database then it works. Therefore, the injection is working but the db is not generated. Also I didn't find any way to trigger the injection of the inner anonymous class. I had to move to its own class. – Neologism

Does Roboblender even work with Eclipse? I keep getting noclassdeffound on AnnotationDatabaseImpl, the class doesn't get generated. – Sudorific

Answer 5

The AnnotationDatabaseImpl is generated at compile time

An explanation is available here

Injected objects became null after upgrading to Roboguice 3
