Building apps for mobile platforms is nuanced, there are many little details that developers coming from a web background often do not consider. This guide is intended to explain some of these nuances and demonstrate how you might factor them in to your application.
We are improving and adding more details to this page. If you'd like to help out, chime in at react-native/14979.
Entering text on touch phone is a challange - small screen, software keyboard. But based on what kind of data you need, you can make it easier by properly configuring the text inputs:
TextInput docs for more configuration options.
Software keyboard takes almost half of the screen. If you have interactive elements that can get covered by the keyboard, make sure they are still accessible by using
KeyboardAvoidingView (see docs).
On mobile phones it's hard to be very precise when pressing buttons. Make sure all interactive elements are 44x44 or larger. One way to do this is to leave enough space for the element,
minHeight style values can be useful for that. Alternatively, you can use
hitSlop prop to increase interactive area without affecting the layout. Here's a demo:
Android API 21+ uses the material design ripple to provide user with feedback when they touch an interactable area on the screen. React Native exposes this through the
TouchableNativeFeedback component. Using this touchable effect instead of opacity or highlight will often make your app feel much more fitting on the platform. That said, you need to be careful when using it because it doesn't work on iOS or on Android API < 21, so you will need to fallback to using one of the other Touchable components on iOS. You can use a library like react-native-platform-touchable to handle the platform differences for you.
