Còn minSdkVersion = "8" thì sao? NotificationListenerService yêu cầu cấp API 18. – samo
Nó đòi hỏi nhưng họ đã cung cấp hỗ trợ cho phiên bản cũ quá – Naga
@Nagendra Họ đã thực sự cung cấp hỗ trợ cho các phiên bản cũ hơn vì tôi không thể tìm thấy nó ở bất cứ đâu. Bạn có thể vui lòng hướng dẫn tôi một nơi nào đó hoặc cho tôi biết chính mình làm thế nào mà có thể được thực hiện? Tôi đã tìm kiếm điều này từ rất nhiều ngày. Tôi thực sự đánh giá cao sự giúp đỡ nào. – Anjani
