Android Basics: Forage app

When I start Testing my app I face this problem:
"Run Android instrumented tests using Gradle" option was ignored because this module type is not supported yet.

I tried to change the versions of the implementations and still not fixed and when I disabled "Run android instrumented tests using gradle" the error doesn't show again because the tests are not passing at all

Any solution !! ( I tried the app by my self and it's working)

typo in step 1:

private val viewModel: ForageableViewModel by activityViewModels {
   ForageableViewModelFactory(
       (activity?.application as BaseApplication).database.foragableDao()
   )
}

foragableDao should be forageableDao

Android Basics: Forage app----------YOU GUYS HAVE A INCOMPLETE IMPORT----URGENT!!!

Can you please complete this import? I can't do it, it is something YOU have too do. I CANNOT run it until you fix.

It just says import R

Then re-upload a FINISHED starter code on the website. Screenshot below

thanks!

Android Basics: Forage app

Dear Madam or Sir,

I am writing regarding the Quiz of this pathway (Use Room for data persistence), not the Project.
The reason I am using the Project Mistake Reporting System is because I could not find an option to report a mistake through the Quiz UI.

Question 3 in the Quiz asks why we need to use 'synchronized' when creating a database.
According to the attached screenshot from the codelab, the correct answers would be the first 2 options:

1. synchronized() is used to avoid race conditions.
2. synchronized() ensures only one thread can enter the block of code at once.

However, this is not the case in the Quiz.
According to the Quiz, the correct answers are:

1. Doing so allows multiple copies of the database to be created.
2. Calling synchronized() allows this code to be safely accessed from multiple threads at once.

I triple-checked the question, and I am pretty sure I am not required to select the FALSE answers.

What am I missing here?

Your help would be very much appreciated.

Thank you,
Ray T.

Dear Experts,
In step 4 at codelab, It's said that " tableName = 'forageable_database' " . Could it be typo here ? Maybe table name can be "forageable" only.
1-Annotate the class using @Entity with the table name "forageable_database".

Codelab link: https://developer.android.com/codelabs/basic-android-kotlin-training-project-forage?continue=https%3A%2F%2Fdeveloper.android.com%2Fcourses%2Fpathways%2Fandroid-basics-kotlin-unit-5-pathway-2%23codelab-https%3A%2F%2Fdeveloper.android.com%2Fcodelabs%2Fbasic-android-kotlin-training-project-forage#3

In fact, the comment in Forageable.kt explains it.

/**
 * Forageable entity to be stored in the forageable_database.
 */

Android Basics: Forage app

private val viewModel: ForageableViewModel by activityViewModels {
ForageableViewModelFactory(
(activity?.application as BaseApplication).database.foragableDao()
)
}

->

private val viewModel: ForageableViewModel by activityViewModels {
ForageableViewModelFactory(
(activity?.application as BaseApplication).database.forageableDao()
)
}

Android Basics: Forage app

After lunching the app in Android Studio, I got a suggested Upgrades:
. Upgrade Gradle version to 7.3.3
. Upgrade Gradle plugins
. Upgrade AGP dependency from 4.1.1 to 7.2.1

I have Done that, then when I tried to Build the project I got an error.

then I searched for a solution I found this:

Then I got another Error:

Delete button causes app to crash

URL of codelab
https://developer.android.com/codelabs/basic-android-kotlin-training-project-forage#0

In which task and step of the codelab can this issue be found?
Step 5

Describe the problem
The delete button on AddForageableFragment causes the app to crash. Immediately after deleting the forageable (and navigating back to ForageableListFragment, the onViewCreated method of AddForageableFragment gets called again returning a null object for the observed data ( "selectedForageable" becomes null)

viewModel.getForageable(id).observe(viewLifecycleOwner, Observer {
forageable = selectedForageable
bindForageable(forageable)
})

Thus, unless you check for the null

if (selectedForageable != null) {
forageable = selectedForageable
bindForageable(forageable)
}

the app will crash. This behaviour is different from the Inventory App of a prior code lab:

https://developer.android.com/codelabs/basic-android-kotlin-training-update-data-room

In the Inventory App, the onViewCreated method of ItemDetailFragment does not get called after deleting the item so there's no need to check for null on selectedItem. I suspect it has to do with the differences in navigation code between the two apps and I would like to know why.

Steps to reproduce?
delete any forageable

Hi

I've completed Forage project step1 -5, but strugging to run the tests in step 6 of the Forage app project on both emulator (Pixel 5 API30) and physical device (pixel 6 pro API33).

Whenever I try to right click and run the PersistenceInstrumentationTests, the existing app that had been running on the device would crash and when I try to re-open the app, I'd get a blank screen. No error message thrown in Android Studio. See screenshot attached

This is the same regardless of whether I'm running the test in the original starter app with no modifications or running in my own version of the completed project. Not sure what I'm doing wrong, but any help is appreciated. Thanks

This is what I see before running the test:

This is what I get after running the test:
