handling state change like orientation or size change

[derysudrajat]

I've tried with this solution but it leaves some bug when we change the orientation or size changed, the previous fragment when recreating it coming stack among the previous fragment and new fragment, anyone has an idea?

Kotlin solution.
For me the best solutions was checking for savedInstanseState and getting fragments from memory.

if (savedInstanceState != null) {
	supportFragmentManager.findFragmentByTag("fragment_1")?.let { fragment1 = it; if (!it.isHidden) activeFragment = it }
	supportFragmentManager.findFragmentByTag("fragment_2")?.let { fragment2 = it; if (!it.isHidden) activeFragment = it }
	supportFragmentManager.findFragmentByTag("fragment_3")?.let { fragment3 = it; if (!it.isHidden) activeFragment = it }
	supportFragmentManager.findFragmentByTag("fragment_4")?.let { fragment4 = it; if (!it.isHidden) activeFragment = it }
	supportFragmentManager.findFragmentByTag("fragment_5")?.let { fragment5 = it; if (!it.isHidden) activeFragment = it }
}
else {
	supportFragmentManager.beginTransaction().add(R.id.fragments_container, fragment5, "fragment_5").hide(fragment5).commit()
	supportFragmentManager.beginTransaction().add(R.id.fragments_container, fragment4, "fragment_4").hide(fragment4).commit()
	supportFragmentManager.beginTransaction().add(R.id.fragments_container, fragment3, "fragment_3").hide(fragment3).commit()
	supportFragmentManager.beginTransaction().add(R.id.fragments_container, fragment2, "fragment_2").hide(fragment2).commit()
	supportFragmentManager.beginTransaction().add(R.id.fragments_container, fragment1, "fragment_1").commit()
}
