Summary: **Motivation** In iOS you cannot dismiss alerts by clicking outside of their box, while on Android you can. This can create some inconsistency if you want to have identical behavior on both platforms. This change makes it possible for Android apps to have irremovable/required alert boxes just like in iOS. This adds an additional parameter to the Alert method. The way to use it is by providing an object with the cancelable property. The cancelable property accepts a boolean value. This utilizes the Android DialogFragment method [setCancelable](https://developer.android.com/reference/android/app/DialogFragment.html#setCancelable(boolean)) **Usage example** ```js Alert.alert( 'Alert Title', null, [ {text: 'OK', onPress: () => console.log('OK Pressed!')}, ], { cancelable: false } ); ``` **Test plan (required)** I added an additional alert to the UIExplorer project where it can be tested. I also added a part in the Dialog Module test to make sure setting canc Closes https://github.com/facebook/react-native/pull/8652 Differential Revision: D3690093 fbshipit-source-id: 4cf6cfc56f464b37ce88451acf33413393454721
UIExplorer
The UIExplorer is a sample app that showcases React Native views and modules.
Running this app
Before running the app, make sure you ran:
git clone https://github.com/facebook/react-native.git
cd react-native
npm install
Running on iOS
Mac OS and Xcode are required.
- Open
Examples/UIExplorer/UIExplorer.xcodeprojin Xcode - Hit the Run button
See Running on device if you want to use a physical device.
Running on Android
You'll need to have all the prerequisites (SDK, NDK) for Building React Native installed.
Start an Android emulator (Genymotion is recommended).
cd react-native
./gradlew :Examples:UIExplorer:android:app:installDebug
./packager/packager.sh
Note: Building for the first time can take a while.
Open the UIExplorer app in your emulator.
See Running on Device in case you want to use a physical device.
Running with Buck
Follow the same setup as running with gradle.
Install Buck from here.
Run the following commands from the react-native folder:
./gradlew :ReactAndroid:packageReactNdkLibsForBuck
buck fetch uiexplorer
buck install -r uiexplorer
./packager/packager.sh
Note: The native libs are still built using gradle. Full build with buck is coming soon(tm).
Built from source
Building the app on both iOS and Android means building the React Native framework from source. This way you're running the latest native and JS code the way you see it in your clone of the github repo.
This is different from apps created using react-native init which have a dependency on a specific version of React Native JS and native code, declared in a package.json file (and build.gradle for Android apps).
