[Android Studio] Screen permission options

알람이 제때 실행될 때 화면 표시 옵션 설정

메소드를 만들어서 onCreate 메소드에 넣어도 되고

아래와 오버라이드해서 직접 넣는 방법도 있다.

// 잠금화면 위에 표시
    override fun onAttachedToWindow() {
        super.onAttachedToWindow()
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O_MR1) {
            setShowWhenLocked(true)
            setTurnScreenOn(true)

            val keyguardMgr = getSystemService(Context.KEYGUARD_SERVICE) as KeyguardManager
            keyguardMgr.requestDismissKeyguard(this, null)
            window.addFlags(
                WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
                        or
                        WindowManager.LayoutParams.FLAG_ALLOW_LOCK_WHILE_SCREEN_ON
            )



        } else {


            window.addFlags(
                WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED    // deprecated api 27
                        or WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD     // deprecated api 26
                        or WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
                        or WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON   // deprecated api 27
                        or WindowManager.LayoutParams.FLAG_ALLOW_LOCK_WHILE_SCREEN_ON
            )

        }
    }

deprecated 된 항목이 꽤 된다.

모든 버전을 커버하기위해서 버전에 따라서 분기점을 만들어서 적용한다.
