Drop in ui not showing

[jin9393]

I used async to fetch token from my server and at the end of the async i call the dropin function and nothing happen after that. However, when i hard coded the token into a string and place it into the dropin function the ui appear. Any way to solve this?

It sounds like fetching the token from the server is the issue since Drop-in launches fine with a hard coded client token.

You can verify your client token is correct by following these steps:

When Drop-in is passed a malformed authorization it finishes with an error.

This example usage in our README shows where that error is referenced back to your activity.

That exception will clue into why Drop-in is not starting.

@jin9393 I'm going to close this. Feel free to reopen it if you are still having issues.

Sorry I forget I posted here as i have been on email with braintree support team. Yes i am still facing the same error since that day.

onActivityResult, i cant cast data to exception. The drop-in ui is still not loading. I have sent over the whole code to the support team and still waiting for their feedback.

You shouldn't cast Intent data to an Exception. See our Usage example.

If some serializable extra exists under DropInActivity.EXTRA_ERROR then the exception will be there.

My bad, I did exactly what is stated on the example and i got this when i try to log the exception.
"Caused by: java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Exception".

Another thing to take note is the onActivityResult resultCode. The resultCode is returning 1 and its not loading into resultCode == Activity.RESULT_OK, even though the drop-in is not loading

Hmm, we do pass a string as a value for DropInActivity.EXTRA_ERROR when BraintreeFragment has an invalid argument which sounds like it would be the Client Token mentioned in your first comment. We should be passing the Exception back and not the String though so we'll work on a fix for that! This would be unrelated to the invalid argument that is being passed in though.

resultCode is returning 1 and its not loading into resultCode == Activity.RESULT_OK, even though the drop-in is not loading

This makes sense, Activity.RESULT_OK == -1. RESULT_OK would be used when Drop-in finishes successfully. If it has an issue it would not return RESULT_OK Activity.RESULT_FIRST_USER == 1 which is the value we use to represent that an error has happened when using Drop-in.

Please check the value you're getting back for DropInActivity.EXTRA_ERROR. If the error is Tokenization Key or client token was invalid we will know that the client token is malformed, and there is some issue with passing the String from your server.

Yes client token was invalid. Thing have been solved. The token from the server pass in with a extra double quote and it was insert into the drop-in ui token. Was solved after removing it. Thanks you very much
