안드로이드 Task stack 뜯어보기

7 분 소요

안드로이드 Task에 대한 내용은 안드로이드 Task 포스팅을 참고할 것.

아래 ADB 명령을 통해 현재 기기에 생성된 Task를 확인할 수 있다.

adb shell dumpsys activity activities > result.txt

Activity의 상태를 보여달라는 명령으로 Activity에 Task 정보가 포함되어 있다.

아래는 현재 단말에 아무것도 실행된 앱이 없는 상태에서 kimss.app.tasktest 앱의 A Activity가 B Activity를 실행시킨 경우에 대한 예이다. (갤럭시 노트5로 테스트)

1.1 Stack #..

여기서 나타나는 Stack은 어떤 기준으로 나오는 것인지 잘 모르겠다.
구조상 Stack 아래에 여러개의 Task가 올 수 있다.

현재 “Stack #1” 에는 실행시킨 테스트앱의 Task가 들어가있고, “Stack #0” 은 런처앱의 Task가 있다.
런처앱에는 2개의 Task가 있는데 각각 “최근앱 목록” 에 해당하는 Task와 “런처 홈”에 해당하는 Task 이다.

현재는 테스트 앱 하나만 띄운 경우인데 여러앱을 띄우고 dump 데이터를 다시 뽑으니 “Stack #1” 에 여러개의 Task가 들어가게 된다.
정확히 어떤 기준으로 Stack이 나뉘어지고 Task들이 자리잡는지 모르겠으나 개발자가 임의로 설정할 수 있고 어떠한 의미를 가진다 라는 내용은 보지 못하였다.

1.2. Task id #…

Stack 아래에 있는 Task가 Activity Task의 정보이다.
하나의 Task는 별도의 Task ID를 가지고 분류된다.

Task의 순서도 안드로이드에서 의미가 있는 정보이다.
상위에 있는 Task가 최근에 실행한 Task이고, 이건 최근 앱 목록에 나오는 순서이기도 하다.

1.3. TaskRecord의 Hist #…

해당 Task의 Activity Stack 정보이다.
“Hist #0 > Hist #1 > Hist #2” 와 같이 순서대로 Stack 구조로 쌓인다.
최상위에 있는 Hist 정보가 Top Activity이고, 최하단에 있는 Hist #0 이 Root Activity 이다.

1.4. Running activities

해당 Stack 아래에 있는 각 Task에서 실행되고 있는 Activity 정보를 보여준다.
그냥 요약해서 보여주는 정보로 큰 의미는 없는것 같다.

2. Task 정보

Task 아래에 있는 정보는 아래와 같다.

Task 내용은 TaskRecord.java 코드를 참고하면 된다.

2.1. taskId

Task를 구분하는 유일 값. (Unique identifier for this task.)

2.2. affinity

Task 친밀도를 나타내는 정보.
(The affinity name for this task, or null; may change identity.)

2.3. rootAffinity

Initial base affinity. or null; does not change from initial root.

2.4. intent

이 Task에서 가장 먼저 실행된 Root Activity를 실행시킨 Intent 정보이다. (The original intent that started the task.)

2.5. affinityIntent

Intent of affinity-moved activity that started this task.

2.6. realActivity

The actual activity component that started the daytask.

2.7. origActivity

The non-alias activity component of the intent.

3. Activity History 정보

Task 아래 Activity Stack의 각 History가 가지는 정보는 아래와 같다.
