Android app relies on keeping all fragments in memory

[voroshkov]

The app uses a "hack" to prevent unloading its screens from memory upon running setOffscreenPageLimit(4)

Chorus-RF-Laptimer/Android/ChorusRFLaptimer/app/src/main/java/app/andrey_voroshkov/chorus_laptimer/MainActivity.java

Line 181 in 1e01318

mViewPager.setOffscreenPageLimit(4);

But this in unlikely the common practice in Android development.
Removing this line crashes the app when switching between screens.
I guess this needs to be fixed (remove setOffscreenPageLimit, and prevent app from crashing)
