Empty login screen Android sample login app

Empty screen In the browser which contains https://xxxx.eu.auth0.com/login?state=blabla. What am I doing wrong? No logs produced.

Are you able to add logging and or view the logcat for your app to see what might be happening?

Good tip. Yes I have been able to see logcat. However now the apps (00-login AND 03-Session-Handling) crash even at startup, not even logcat. Tried several devices (Genymotion, samsung Note 8,

strings.xml is adapted to my auth0 settings etc.

It gives on the android screen:
“Session Management is stopped” or
“Hosted Login Page is stopped”

Debugging
the source, at that moment, tries to execute statement:

auth0 = new Auth0(this);

Nothing I have changed, AFAIK, strange…

I noticed that if I downgrade
compil ‘com.auth0.android:auth0:1.+’
to
compile ‘com.auth0.android:auth0:1.13.0’ or lower
It gives the behavior I got in the OP, logcat with library 1.13.0:

which sample are you referring to? are you following the Android quickstart ?

Yes, following it to the letter more than once…

Well almost, I have to admit
I changed:
in build.gradle:
i added
google()
to allprojects

and what made the difference:
I , have to admit, I customized the login page with a logo in js code with a syntax error, like
logo : '‘url’
corrected it to
logo : ‘url’

now it worrks with
compile ‘com.auth0.android:auth0:1.13.0’

however
compile ‘com.auth0.android:auth0:1.+
still keeps crashing’
