Lineの認証画面から復帰した時に 「FAILED_A2A_LOGIN errorCode=2」 about line-sdk-starter-android HOT 21 CLOSED

FAILED_A2A_LOGIN Error is mostly caused if the apk signature is different from the technical configuration on channel console.
Please confirm it and if you change the configuration signature, please wait some time so it can be applied.

FAILED_A2A_LOGIN Error is mostly caused if the apk signature

I tried to check apk signature 10 or more times.(it's Google Play apk's signature)
What possible causes of the other ?

thanks

There may be your channel in the development of the state(the status is developing), this time can only get your developer's account authorization, other accounts authorization failed

I have one question: How can i get the FRIEND LIST permission?

from line-sdk-starter-android.

@Kevin-Misfit
Sorry it is not provided to public at this moment.

from line-sdk-starter-android.

So, it's only for internal use? but why did you guys write these information that more than just login on the document, make us believe we can get more permissions, and we can not get these, so sad!!

from line-sdk-starter-android.

@Kevin-Misfit
I meant its not open to public. It could be allowed in some strategy / business partnership cases.
I'll be working to reduce those gaps for you guys
