Incompatible Kotlin/Gradle Version on Branch Step.01-Exercise-Creating-and-Adding-a-Fragment

Branch Step.01-Exercise-Creating-and-Adding-a-Fragment had gradle errors for me. Android Studio forced upgrade of Gradle to 3.3.0 and then I made changes to upgrade the Kotlin version so that the kotlin-gradle-plugin was supported. I've attached a patch file of the changes.
0001-Update-gradle-and-kotlin-versions.zip

deprecated way for options Menu

setHasOptionsMenu(true) is deprecated at title fragment
onCreateOptionsMenu is deprecated at title fragment
onOptionsItemSelected is deprecated at title fragment

Gradle sync failure. Could not find androidx.navigation:navigation-safe-args-gradle-plugin:1.0.0-alpha07.

Cloned the repository. On sync the following occurs:

Adding the Up-Button causes app crashing

I had an issue with adding the Up-Button, where my App crashed with the message that my MainActivity would not have a NavController set.

I fixed this by accessing the navHostFragment directly:
// Delete this line
val navController = this.findNavController(R.id.myNavHostFragment)

//Replace it with:
val navHostFragment = supportFragmentManager.findFragmentById(R.id.myNavHostFragment) as NavHostFragment
val navController = navHostFragment.navController

//Continue with
NavigationUI.setupActionBarWithNavController(this, navController)

Can't use safe args

After adding safe-args dependency and plugins, there are no generated class.
GameFragmentDirections doesn't show up.

When I type below code in GameFragment Kotlin file, an error shows up at GameFragmentDirections. The error says unresolved references
(screenshot as below)

Unsolved referense

What is it supposed to refer to GameoverFragmentDirections, TitleFragmentDirections?

Fails to build in Android Studio 3.4, citing Gradle errors or IDE fatal error

This code does not build in Android Studio 3.4. It cites these Gradle errors if I choose "Don't remind me again for this project" when asked to update Gradle, as the lesson asks:

When I do update Gradle contrary to the lesson plans, and then rebuild, I get this "IDE Fatal Error":

I've been having a lot of trouble going through these lessons in Android Studio 3.4.

E/ViewRootImpl: sendUserActionEvent() mView == null

when i click on menu "about" this is error has shown "E/ViewRootImpl: sendUserActionEvent() mView == null" ,
by the way i use samsung with kit kat android version

ActivityMainBinding and FragmentTitleBinding unresolved reference

I don't know if this only happened to me, but when I tried binding the layout to the TitleFragment, the com.example.android.navigation.databinding.ActivityMainBinding (in MainActivity.kt) and com.example.android.navigation.databinding.FragmentTitleBinding (in TitleFragment) imports were giving me an unresolved reference error and consequently a compilation error.

I fixed them by adding kapt "com.android.databinding:compiler:3.1.4" to the app build.gradle file and that seems to have done the trick, but given that I am somewhat of a novice I'm unsure whether it's just a quick fix or it was the right thing to do. Could you please confirm? Thanks.

Navigation drawer not closing

Navigation drawer once opened by pressing hamburger icon does not getting closed by pressing it again.

Redundant code in GameFragment.kt (Branch: Step.03-Exercise-Conditional-Navigation)

andfun-kotlin-android-trivia/app/src/main/java/com/example/android/navigation/GameFragment.kt

Lines 90 to 99 in 0570399

 // The first answer in the original question is always the correct one, so if our 

 // answer matches, we have the correct answer. 

 if (answers[answerIndex] == currentQuestion.answers[0]) { 

 questionIndex++ 

 // Advance to the next question 

 if (questionIndex < numQuestions) { 

 currentQuestion = questions[questionIndex] 

 setQuestion() 

 binding.invalidateAll() 

 } else {

The code in line number 96 is redundant because the setQuestion() method also does that. (line 126)

andfun-kotlin-android-trivia/app/src/main/java/com/example/android/navigation/GameFragment.kt

Lines 125 to 128 in 0570399

 private fun setQuestion() { 

 currentQuestion = questions[questionIndex] 

 // randomize the answers into a copy of the array 

 answers = currentQuestion.answers.toMutableList()

The code in the setQuestion() method can't be changed because it also sets the first question. Therefore it is better to remove the code in line 96.

Any way to remove action bar on some fragments?

Hi,
Watched tutorials and implemented on my project. I wonder if there is any way to hide action bar on some fragments?

AndroidX implementation

This project seems to use, old android versioning for navigation, thus, leading to lot's of confusion when on some exercise. Is there a way, we can rewrite the commit history and fix the versioning and move the code to proper AndroidX?

Gradle sync failure. Failure to resolve - android.arch.navigation:navigation-fragment-ktx:2.3.0, - android.arch.navigation:navigation-ui-ktx:2.3.0

GameWonFragment compiler error when implementing SafeArgs

The following GameWonFragment line:
val args = GameWonFragmentArgs.fromBundle(arguments)

Generates the compiler error:
Type mismatch: inferred type is Bundle? but Bundle was expected

// found the fix here: https://github.com/googlecodelabs/androi-navigation/issues/49
val args: GameWonFragmentArgs by navArgs()

Step.09-Solution not working

It is giving java.lang.IllegalArgumentException: No drawer view found with gravity LEFT
and marking return NavigationUI.navigateUp(navController, drawerLayout) as the issue.

I tried everything like setting gravity to right|left or just left, even degrading the dependencies, but it's not working at all.

Please someone help as I wasted a lot of time with this.

Method onSupportNavigateUp: Sequence of method arguments interchanged

Sequence of method arguments interchanged:

Class:  MainActivity
Method: onSupportNavigateUp()

Change from:
return NavigationUI.navigateUp(drawerLayout, navController)
to:
return NavigationUI.navigateUp(navController, drawerLayout)

GameWonFragment compiler error when passing fragment in ShareCompat.IntentBuilder.from()

In GameWonFragment, in the fun getShareIntent the line:

return ShareCompat.IntentBuilder.from(activity)
                .setText(getString(R.string.share_success_text, args.numCorrect, args.numQuestions))
                .setType("text/plain")
                .intent

gives the error:
"Type mismatch. Required: Activity, Found: Fragment Activity?"

Error is in starter code branch, and Step 11 Solution Branch so I guess it is in every branch but I have not checked yet.
