Include jsr-305 jar file in project libraries. Use @nullable with fields and RoboGuice will stop complaining about null objects.

For Android Studio:

Add the following to build.gradle:

dependencies {
    ...
    // For @Nullable/@NonNull
    compile 'com.android.support:support-annotations:+'
}

Go to File / Setting → Project Settings → Inspections and search for "nullable".

In Constant conditions & exceptions and @NotNull/@Nullable problems, click Configure annotations and select Android's annotations.

You may also want to check Suggest @Nullable annotations… under Constant conditions & exceptions, or possibly tweak other options.
