Janic Duplessis 9f239d7914 Use react.gradle from repo root instead of copy in RNTester
Summary:
RNTester used a copy of the main react.gradle file instead of the real one. Recent changes to the real file caused builds to fail with older gradle versions but was not caught by CI because it wasn't using that file for RNTester. That copy of react.gradle is just a leftover from when projects included a copy instead of importing the one in RN directly.

Note: CI WILL fail with this PR, if we have trouble landing this I can add the revert in this commit too but wanted to keep it as 2 separate commits.

Tested that building RNTester actually fails now that it uses react.gradle with recent changes, then tested that is builds properly when reverting d16ff3bd8b92fa84a9007bf5ebedd8153e4c089d.

RNTester

The RNTester 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 RNTester/RNTester.xcodeproj in 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 :RNTester:android:app:installDebug
./scripts/packager.sh

Note: Building for the first time can take a while.

Open the RNTester 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 rntester
buck install -r rntester
./scripts/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).
