Profiling Android UI Performance

We try our best to deliver buttery-smooth UI performance by default, but sometimes that just isn't possible. Remember, Android supports 10k+ different phones and is generalized to support software rendering: the framework architecture and need to generalize across many hardware targets unfortunately means you get less for free relative to iOS. But sometimes, there are things you can improve (and many times it's not native code's fault at all!). The first step for debugging this jank is to answe

Flexbox#padding

padding number

Image#onProgress

iosonProgress function Invoked on download progress with {nativeEvent: {loaded, total}}

ProgressViewIOS#progressImage

progressImage Image.propTypes.source A stretchable image to display as the progress bar.

TabBarIOS.Item#badge

badge string, number Little red bubble that sits at the top right of the icon.

Modal#onRequestClose

onRequestClose Platform.OS === 'android' ? PropTypes.func.isRequired : PropTypes.func

ScrollView#directionalLockEnabled

iosdirectionalLockEnabled bool When true, the ScrollView will try to lock to only vertical or horizontal scrolling while dragging. The default value is false.

BackAndroid.exitApp()

static exitApp()
