App development app crashing, can I get some help?

[AC Question]

App development app crashing

I have built an app ( My first one im very new to this), i have integrated Facebook login onto my app and the first time i ran it and logged in it worked and logged me in, then i wanted to see if i could log in and out double checking it really did work. Now when i start the app im always already signed in, when i click log out it does but then if i try to log back in to the app it says "Unfortunately, (appname) has stopped". I cant find what i have done wrong as there are no errors on android studio and debug mode shows nothing either.

If anyone might be able to help i would appreciate it.

Re: App development app crashing

Have you tried with adb shell/logcat while running your app? Maybe it can be useful.

LogCat will help you indeed,.. are you using AndroidStudio? if you do,. wire up your phone, run or debug your app and take a look in the logcat window (by default on the "Android" tab at the bottom of your dev-env.

By default it will give you a lot more log results than you need but you can set a filter. It helps if you create a filter and set the package name to yours.
