착용 앱을 열 때마다 Android Wear를 휴대 전화와 동기화하십시오.

Question

Android 용 휴대 전화 및 착용 용 기본 날씨 앱을 구현하려고합니다. 응용 프로그램은 웹 API에서 데이터를 가져온 다음 전화 상에 표시합니다. 앱이 Wear에서 열려 있고 전화에서 열면 지금 날씨에 동기화됩니다. 그리고 만약 당신이 전화로 날씨를 바꾼다면, 그것은 착용시에도 바뀝니다. 착용 응용 프로그램을 열 때마다 착용 응용 프로그램이 휴대 전화에서 날씨를 가져 오도록 만들고 싶습니다. 메시지를 통해 전화를 "핑"하고 전화가 데이터 맵을 통해 정보를 전송하도록 구현하려고했습니다. 전화가 데이터 맵을 보냈다고 말했지만 마모가 전화에서 데이터 맵을 수신하지 않는다는 점을 제외하면이 방식이 효과적입니다.

는 applicationID가에 대한 build.gradle에서 동일 있는지 확인 모바일 및 착용 앱. 또한 두 앱 모두 buildTypes 부분과 signingConfigs 부분이 동일해야합니다. Source.Long.toString(System.currentTimeMillis())을 전송하여 매번 변경 될 때이를 확인할 수도 있습니다.
