Bug: Product config function fetchAndActivate is not working as expected.

[SuhasTS]

Function fetchAndActivate() in class CTProductConfigController is fetching the new values but failing to activate the same in some scenarios.

fun setup(context: Context) {
        Log.d("ProductExperience", "setup: ")
        val clevertapApi = CleverTapAPI.getDefaultInstance(context) ?: return
        val productConfigController = clevertapApi.productConfig()
        productConfigController.setDefaults(R.xml.product_experience_defaults)
        clevertapApi.setCTProductConfigListener(object : CTProductConfigListener {
            override fun onActivated() {
                Log.d("ProductExperience", "onActivated: ${productConfigController.getString("Debug")}")
            }

            override fun onFetched() {
                Log.d("ProductExperience", "onFetched: ${productConfigController.getString("Debug")}")
            }

            override fun onInit() {
                Log.d("ProductExperience", "onInit: ${productConfigController.getString("Debug")}")
                productConfigController.activate()
                productConfigController.fetchAndActivate()
            }
        })
    }

Logs on running the above function

D/ProductExperience: setup: 
D/ProductExperience: onInit: 
D/ProductExperience: onActivated: Default value in xml
D/ProductExperience: onInit: Default value in xml
D/ProductExperience: onActivated: Default value in xml
D/ProductExperience: onFetched: Default value in XML  //onactivated callback is missing after this

@SuhasTS Thanks for the time & effort to raise a fix for this.

Before going ahead with the PR, Can you please explain the scenario in which it's failing & the solution you have proposed will work to handle the scenario?

[SuhasTS]

The sample function that I have shared is the scenario where it fails.
Basically when you call fetchAndActivate and previously called activate function is completed after that(activate function is asynchronous) the variable isFetchAndActivating is reset to false as a result, it only fetches the new values but never activates them.
The PR which I have raised resolves this issue.

@SuhasTS As per my understanding , you are calling activate() & fetchAndActivate() method one after another in a sequence. So the isFetchAndActivating = true is getting overridden.

Please confirm.

[SuhasTS]

Yes.

We will including the fix in our next planned release.
Will keep you informed.
