Reporting risk level

Pass the highest risk level of user's exposure from last 14 days detected by Exposure Notification Framework to PWA.

Steps:

• PWA request reporting risk level
  • JS Bridge UseCase: OnGetBridgeDataUseCase
  • JS Bridge Data Type: OutgoingBridgeDataType.ANALYZE_RESULT
• Get all data about exposures from local database
  • UseCase: GetAnalyzeResultUseCase
  • Repository function: ExposureRepository.getAllResults()
  • Repository implementation: ExposureRepositoryImpl.getAllResults()
• Filter exposure with the highest risk score from exposures
  • UseCase: GetAnalyzeResultUseCase
• Calc risk level from risk score (max riskScore = 4096):
  • riskScore < 1500 -> NO_RISK
  • riskScore < 3000 -> MIDDLE_RISK
  • else -> HIGH_RISK
  • Enum function: RiskLevelData.fromRiskScore(riskScore: Int)
• Pass calculated risk level to PWA by returning json with result model back through OnGetBridgeDataUseCase
  • JS Bridge UseCase: OnGetBridgeDataUseCase
  • JS Bridge Data Type: OutgoingBridgeDataType.ANALYZE_RESULT
  • Json composer: OutgoingBridgeDataResultComposer.composeAnalyzeResult(exposure: ExposureItem)
