Summary: The problem is that whenever an app is shutdown, and then reopened, the flipper dir gets reset when getting the CSR for connecting to flipper. This causes the first connection attempt to fail always, and it goes through the whole cert exchange, taking longer than necessary. Fixes it by loading the csr from disk if it's not loaded yet, without blowing away the whole certs state. A side effect of this would be that as long as some file exists where the csr lives, flipper state would never get reset, so it wouldn't be able to fix itself automatically anymore. To keep that working, I've made `resetFlipperDir()` public and am calling it explicitly when starting certificate exchange. This should ensure that we still reset when we need to, but not unnecessarily. The reason it went wrong is that getCSR used to be called only at cert exchange, when resetting and generating a new one was always desirable. However, when we shipped the fix for changeable android serials, it started to be used as a normal getter.

Mobile development
Flipper aims to be your number one companion for mobile app development on iOS and Android. Therefore, we provide a bunch of useful tools, including a log viewer, interactive layout inspector, and network inspector.
Extending Flipper
Flipper is built as a platform. In addition to using the tools already included, you can create your own plugins to visualize and debug data from your mobile apps. Flipper takes care of sending data back and forth, calling functions, and listening for events on the mobile app.
Contributing to Flipper
Both Flipper's desktop app and native mobile SDKs are open-source and MIT licensed. This enables you to see and understand how we are building plugins, and of course, join the community and help improve Flipper. We are excited to see what you will build on this platform.

- iOS developer tools (for developing iOS plugins)
- Android SDK and adb
Building from Source
Desktop
Running from source
git clone https://github.com/facebook/flipper.git
cd flipper
yarn
yarn start
NOTE: If you're on Windows, you need to use Yarn 1.5.1 until this issue is resolved.
Building standalone application
Provide either --mac, --win, --linux or any combination of them
to yarn build to build a release zip file for the given platform(s). E.g.
yarn build --mac --version $buildNumber
You can find the resulting artifact in the dist/ folder.
iOS SDK + Sample App
cd iOS/Sample
rm -f Podfile.lock
pod install --repo-update
open Sample.xcworkspace
<Run app from xcode>
You can omit --repo-update to speed up the installation, but watch out as you may be building against outdated dependencies.
Android SDK + Sample app
Start up an android emulator and run the following in the project root:
./gradlew :sample:installDebug
Documentation
