Dagger 2 / DialogFragment / appcompat-v7:22.2.0 causes "cannot access DialogStyle"

[jeffdcamp]

I don't know if this is an issue with Dagger 2.0 or Android AppCompat....

We are using android.support.v4.app.DialogFragment and Dagger 2. When switching from appcompat-v7:22.1.0 to appcompat-v7:22.2.0 Dagger annotation processor causes the following error:

===== Gradle log ===== :processDebugJavaRes UP-TO-DATE :compileDebugJavaWithJavac error: cannot access DialogStyle class file for android.support.v4.app.DialogFragment$DialogStyle not found Consult the following stack trace for details. com.sun.tools.javac.code.Symbol$CompletionFailure: class file for android.support.v4.app.DialogFragment$DialogStyle not found 1 error :compileDebugJavaWithJavac FAILED

Very Simple Sample Code which causes the error:

===== TestFragment.java ===== import android.support.v4.app.DialogFragment; import org.company.project.Prefs; import javax.inject.Inject;

public class TestFragment extends DialogFragment { @Inject Prefs prefs; }

===== AppComponent.java ===== import org.company.project.ui.TestFragment; import javax.inject.Singleton; import dagger.Component;

@Singleton @Component(modules = AppModule.class) public interface AppComponent { void inject(TestFragment target); }

I'm seeing this issue as well :-\

I am getting the same results with my dialogs.

It seems that this might be a AppCompat issue... there seems to be similar discussions about this same issue with other annotation processing libraries:

and

I just found a TEMPORARY workaround... till appcompat fixes this issue:

1. Create the following package in your project src/main/java

android.support.v4.app

1. Create the following new file:

DialogFragment$DialogStyle.java

1. Contents package android.support.v4.app;

// todo remove this file when fixed in appcompat (https://code.google.com/p/android/issues/detail?id=175086) public @interface DialogFragment$DialogStyle { }

@jeffdcamp You're proposed solution doesn't seem to work for me I now get the following error:

@marcoRS Interesting.... I have applied this work-around to 4 different projects and verified that these projects compile correctly on several machines... I compile with java 8 on one machine and java 7 on another machine....

Same issue with @jeffdcamp Is updating jre etc helpful?

[RobertoArtiles]

Getting the same error as @marcoRS

+1. Got the same error as @marcoRS

same error as @marcoRS

[jeffdcamp]

@marcoRS, @RobertoArtiles, @malroy89 , @AlexanderThiele I found another work-around.... a bit more ugly... but has gotten us around this issue (including the NPE on the above work-around) till appcompat 22.2 is fixed.

• Create the following package in your project src/main/java

android.support.v4.app

• Copy the Google v4 FragmentDialog.java code

https://android.googlesource.com/platform/frameworks/support/+/refs/heads/master/v4/java/android/support/v4/app/DialogFragment.java

• Rename the class (to something like TempFragmentDialog). You will get a "Duplicate" class error if you don't rename the class.
• Any FragmentDialog, in your project, that has @Inject will need to extend your copy of the FragmentDialog (example: public class MyFragmentDialog extends TempFragmentDialog)

[marcoRS]

@jeffdcamp Thanks for the workaround. I however had to change every class that extended from DialogFragment, not just the classes that used @Inject

[floating-cat]

It was fixed on Android Support 22.2.1.

Fixed
