[devfd]

what is your testing environment - RN version, what kind of emulator or device ?
thanks

[seanscal]

I'm using RN 18.1 and android studio nexus 5 emulator

[devfd]

do you observe the same issue when running the sample app ?

also the issue seems to come from the logout method. are you correctly logged-in when you call this method ?

[seanscal]

I deleted my entire index.android.js file and replace the contents with the sample and I still get the same thing. It seems can't log in as this comes up immediately after starting my app. Everything is still working in Xcode and the iphone emulator but not android.

[devfd]

just tested the sample app on a real nexus 5. everything works just fine (login & logout)

if you can share your code I could be able to help you.

my problem solved with this:

cd android
gradlew clean
gradlew assembleDebug --stacktrace

i hope that works for you
