Flipper helps you debug Android and iOS apps running in an emulator/simulator or connected physical development devices. Flipper consists of two parts:

- The desktop app for macOS
- The native mobile SDKs for Android and iOS

To use Flipper, you need to add the mobile SDK to your app.

## Setup

### Desktop app

The desktop part of Sonar doesn't need any particular setup. Simply [download the latest build](https://www.facebook.com/fbflipper/public/mac) of our app and launch it. The desktop app is available for macOS and requires a working installation of the Android/iOS development tools on your system.

Once you start Flipper and launch an emulator/simulator or connect a device, you will already be able to see the device logs in Flipper. To see app specific data, you need to integrate our native SDKs with your app.

### Setup your Android app

Add the following permissions to your AndroidManifest.xml. The SDK needs these to communicate with the desktop app on localhost via adb. It won't make any external internet requests.

```
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
```

Flipper is distributed via JCenter. Add dependencies to your `build.gradle` file.

```
repositories {
  jcenter()
}

dependencies {
  debugImplementation 'com.facebook.flipper:flipper:0.6.16'
}
```

Now you can initialize Flipper in your Application's `onCreate`-method like this:

```java
public class MyApplication extends Application {

  @Override
  public void onCreate() {
    super.onCreate();
    SoLoader.init(this, false);

    if (BuildConfig.DEBUG && SonarUtils.shouldEnableSonar(this)) {
      final SonarClient client = AndroidSonarClient.getInstance(this);
      client.addPlugin(new MySonarPlugin());
      client.start();
    }
  }
}
```

### Setup your iOS app

To integrate with an iOS app, you can use [CocoaPods](https://cocoapods.org). Add the mobile Flipper SDK and its dependencies to your `Podfile`:

```ruby
project 'MyApp.xcodeproj'
source 'https://github.com/facebook/Sonar.git'
source 'https://github.com/CocoaPods/Specs'
# Uncomment the next line to define a global platform for your project
swift_version = "4.1"
sonarkit_version = '0.6.16'

target 'MyApp' do

  pod 'SonarKit', '~>'+sonarkit_version
  # Layout and network plugins are not yet supported for swift projects
  pod 'SonarKit/SonarKitLayoutComponentKitSupport', '~>' + sonarkit_version
  pod 'SonarKit/SKIOSNetworkPlugin', '~>' + sonarkit_version

  post_install do |installer|

        installer.pods_project.targets.each do |target|
            if ['YogaKit'].include? target.name
                target.build_configurations.each do |config|
                    config.build_settings['SWIFT_VERSION'] = swift_version
                end
            end
        end
    end
end
```

and install the dependencies by running `pod install`. When you open the Xcode workspace file for your app, you now can import and initialize Flipper in your AppDelegate.

```objective-c
#import <SonarKit/SonarClient.h>

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
#if DEBUG
  SonarClient *client = [SonarClient sharedClient];
  [client addPlugin:[MySonarPlugin new]];
  [client start];
#endif
  ...
}
@end
```

<div class='warning'>

- We haven't released the dependency to CocoaPods yet, here is the [issue](https://github.com/facebook/flipper/issues/132) by which you can track.
- If you do not use CocoaPods as a dependency management tool then currently there is no way to integrate SonarKit other than manually including all the dependencies and building it.
- For Android, Flipper works with both emulators and physical devices connected through USB. However on iOS, we don't yet support physical devices.
- The Flipper layout plugin isn't supported in Swift projects since they include C++ dependencies. We're working on supporting it for Swift apps. You can join the discussion on the [issues page](https://github.com/facebook/flipper/issues).

## Ready for takeoff

Finally, you need to add plugins to your Flipper client. See [Network Plugin](network-plugin.md) and [Layout Inspector Plugin](layout-plugin.md) for information on how to add them.
