Fragments reset to first page when screen rotates, or the app completely closes about material-intro

Can you record a vido of your screen?

I implemetd this the same way as it is done in the example app, however the issue is that the app closes in my case

[heinrichreimer]

So you used the gradle dependency and I guess SimpleSlide?
And the example App works?

Fragment lifecycle is tricky especially when used in a ViewPager. Did you override anything lifecycle related in your activity?
You can also try the new version 1.4.

Sorry i do not believe i fully understand? I am not all that knowledgeable with java. My drawer activity is my splash screen, which checks a preference for if it is the first time the app is starting. If so, then it is set to execute the activity which extends the IntroActivity and implements the SimpleSlide. I can attach some code if necesary. My app is based off an open-source dashboard, called Polar if this is of any use to you. :-)

That would be useful!

Sorry its not formatted correctly.

Hey there never mind. The issue seems to be resolved! It was an issue on my end, where I was calling the intro from the splash screen, and the splash screen would close. So when you rotated it there was no activity holding the intro I believe.

Anyway I've added your awesome into into my app! Feel free to check it out! https://play.google.com/store/apps/details?id=com.erc.software.materialwallpapers

Thank you very much for your assistance and sorry for the inconvenience.

[heinrichreimer]

Yep, that's the issue here. You should start the intro in your MainActivity.java. I should add a demo for implementing the intro with a splash screen
