Hi @OrenZak , I have a question about the getUserLoginState, setJWT and logout methods

In Kin.login(JWT) method, you use AuthRepository.getInstance().getUserLoginState(JWT) to check the loginState. If the input user_id or device_id in jwt are different with the cached data, the logout method will be invoked.

But the cached data will not be clear if Kin SDK is not logged in before because the result of isAccountLoggedIn.compareAndSet(true, false) is false in logout method.

For example, user use user_id_1 to get jwt_1 and auth_token_1 and login Kin Successfully, then he logout app without call Kin#logout(developers forget to call Kin.logout when logout app's account) and kill app. In next time he use user_id_2 to try to login, but SDK will use user_id_1's authToken to try log in because user_id_1's authToken is not expired.

Hi @OrenZak , a NPE occurred in EcosystemActivity. The SDK version is 1.0.1. Here is the crash log:

Native earn option throws following exception

com.kin.ecosystem.common.exception.ServiceException: The Ecosystem server returned an error. See underlyingError for details

simply adding
implementation ('com.github.kinfoundation.kin-ecosystem-android-sdk:sdk:0.1.+')
causes the following when compiling my app
AAPT: error: duplicate value for resource 'attr/orientation' with config
AAPT: error: resource previously defined here.
(with a reference to a gradle cache file containing the definition of KinEcosystemDashView

:-(

update: it's a conflict with
implementation ("com.android.support:gridlayout-v7:27.1.1")

Hi @OrenZak , we watched a kotlin exception occurred in OnboardingFragment. SDK version is 1.0.1. Here is the crash log:

If you click the Transaction History when the spend offers is not loaded, it will occurs KotlinNullPointerException.

See the log below:

I would like to add my Android app to the Kin Ecosystem. I have read the documentation for the Kin Ecosystem Android SDK. I want to make sure I am on the right track. My app tracks user location outdoor/indoor and performs location analytics on user location history. Unlike other LBS apps no user location data leaves the device (phone). The app does not rely on the cloud to do its work.

My initial thought is to offer users of my app kin earn opportunities if they allow my app to track their location, and additional kin earn opportunities if they allow the app to perform location analytics on their location information. Does this make sense? Are there other earn opportunities related to location data and analytics?

It's not clear to me how I would add to my app the function to let users sell their location data and analytics in the Kin Ecosystem. I would appreciate thoughts on this.

I would also appreciate it if anyone would let me know about other location related applications currently in the Kin Ecosystem.

Thanks,

Alex Donnini

P.S. I posted this question on Stack Overflow too

Hi,

We were wondering what exactly is included in the SDK. Does it provide UI components for things like user balance and transactions?

We're looking to use this package in a React Native app and are wondering how much work it would be for us to rewrite it in Javascript. Can all actions be accomplished via API calls to the server? What does this package add beyond that?

I am having issues with the current FileProvider implementation in your SDK when another SDK uses FileProvider too:

:app:processDebugManifest

> Manifest merger failed with multiple errors, see logs

I created a fix, PR is on its way.

Hello @OrenZak , we watched two JSON crashes in SDK 1.0.1. Here are the logs:

serialize

deserialize

If you click "Kin Balance" quickly in MarketPlace when "Earn/Spend" is not displayed, kin will crash. Here is the log:
