Implement SonarPlugin

Create a class implementing SonarPlugin.

Android

public class MySonarPlugin implements SonarPlugin {
  private SonarConnection mConnection;

  @Override
  public String getId() {
    return "MySonarPlugin";
  }

  @Override
  public void onConnect(SonarConnection connection) throws Exception {
    mConnection = connection;
  }

  @Override
  public void onDisconnect() throws Exception {
    mConnection = null;
  }
}

iOS

@interface MySonarPlugin : NSObject<SonarPlugin>
@end

@implementation MySonarPlugin

- (NSString*)identifier { return @"MySonarPlugin"; }
- (void)didConnect:(SonarConnection*)connection {}
- (void)didDisonnect {}

@end

C++

class MySonarPlugin : public SonarPlugin {
public:
  std::string identifier() const override { return "MySonarPlugin"; }
  void didConnect(std::shared_ptr<SonarConnection> conn) override;
  void didDisconnect() override;
};

Using SonarConnection

Using the SonarConnection object you can register a receiver of a desktop method call and respond with data.

Android

connection.receive("getData", new SonarReceiver() {
  @Override
  public void onReceive(SonarObject params, FlipperResponder responder) throws Exception {
    responder.success(
        new SonarObject.Builder()
            .put("data", MyData.get())
            .build());
  }
});

iOS

@interface MySonarPlugin : NSObject<SonarPlugin>
@end

@implementation MySonarPlugin

- (NSString*)identifier { return @"MySonarPlugin"; }

- (void)didConnect:(SonarConnection*)connection
{
  [connection receive:@"getData" withBlock:^(NSDictionary *params, FlipperResponder *responder) {
    [responder success:@{
      @"data":[MyData get],
    }];
  }];
}

- (void)didDisonnect {}

@end

C++

void MySonarPlugin::didConnect(std::shared_ptr<SonarConnection> conn) {
  conn->receive("getData", [](const folly::dynamic &params,
                             std::unique_ptr<FlipperResponder> responder) {
    dynamic response = folly::dynamic::object("data", getMyData());
    responder->success(response);
  });
}

Push data to the desktop

You don't have to wait for the desktop to request data though, you can also push data directly to the desktop.

Android

connection.send("MyMessage",
    new SonarObject.Builder()
        .put("message", "Hello")
        .build()

iOS

[connection send:@"getData" withParams:@{@"message":@"hello"}];

C++

void MySonarPlugin::didConnect(std::shared_ptr<SonarConnection> conn) {
  dynamic message = folly::dynamic::object("message", "hello");
  conn->send("getData", message);
}
