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

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

To use Sonar, 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/sonar/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 Sonar and launch an emulator/simulator or connect a device, you will already be able to see the device logs in Sonar. 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" />
```

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

```
repositories {
  jcenter()
}

dependencies {
  debugImplementation 'com.facebook.sonar:sonar:0.6.11'
}
```

Now you can initialize Sonar 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 Sonar 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"

target 'MyApp' do

  pod 'SonarKit', '~>0.6'
  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 Sonar 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/Sonar/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, Sonar works with both emulators and physical devices connected through USB. However on iOS, we don't yet support physical devices.
* Also Sonar doesn't work with swift projects as its written in C++ and had C++ dependencies. But we are working on supporting sonar for swift projects. You can find this issue [here](https://github.com/facebook/Sonar/issues/13)

## Ready for takeoff

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