Question

I’m new in using view pager, I’ve done everything correctly, I conveted my activities into fragments and put them in FragmentPagerStateAdapter.
When testing it in the emulator, what I noticed is that the onCtreate to the onResume are called one fragment before the actual visibility on the view pager – it makes sense, the device wants to get ready for the next step, but the problem is that I have one fragment which calls a dialog every onStart so that actually happens on the wrong fragment.

What should be done?

You can use an OnPageChangeListener on your ViewPager to detect when you navigate to the right fragment.
