為配合主幹穩定開發模型，並確保生態系統的平台穩定性，我們將於 2026 年起，在第 2 季和第 4 季將原始碼發布至 AOSP。如要建構及貢獻 AOSP，建議使用 android-latest-release，而非 aosp-main。android-latest-release 資訊清單分支版本一律會參照推送至 AOSP 的最新版本。詳情請參閱「Android 開放原始碼計畫變更」一文。

公用方法

captureLayers

public static void captureLayers (ClientImpl client, 
                String viewRoot, 
                DebugViewDumpHandler handler)

參數
`client`	`ClientImpl`
`viewRoot`	`String`
`handler`	`DebugViewDumpHandler`

captureView

public static void captureView (Client client, 
                String viewRoot, 
                String view, 
                DebugViewDumpHandler handler)

參數
`client`	`Client`
`viewRoot`	`String`
`view`	`String`
`handler`	`DebugViewDumpHandler`

clientDisconnected

public void clientDisconnected (ClientImpl client)

用戶端已離開。可用於清除與這個用戶端連線相關聯的任何資源。

參數
`client`	`ClientImpl`

clientReady

public void clientReady (ClientImpl client)

用戶端已準備就緒。當用戶端判斷為 DDM 感知型 (通常是在收到 HELO 回應後)，監控執行緒會在所有處理常式上呼叫這個方法。

處理常式可利用這個機會初始化用戶端活動。因為我們很有可能想傳送訊息給用戶端，所以這個方法可能會擲回 IOException。

參數
`client`	`ClientImpl`

dumpDisplayList

public static void dumpDisplayList (Client client, 
                String viewRoot, 
                String view)

參數
`client`	`Client`
`viewRoot`	`String`
`view`	`String`

dumpTheme

public static void dumpTheme (ClientImpl client, 
                String viewRoot, 
                DebugViewDumpHandler handler)

參數
`client`	`ClientImpl`
`viewRoot`	`String`
`handler`	`DebugViewDumpHandler`

dumpViewHierarchy

public static void dumpViewHierarchy (Client client, 
                String viewRoot, 
                boolean skipChildren, 
                boolean includeProperties, 
                boolean useV2, 
                DebugViewDumpHandler handler)

參數
`client`	`Client`
`viewRoot`	`String`
`skipChildren`	`boolean`
`includeProperties`	`boolean`
`useV2`	`boolean`
`handler`	`DebugViewDumpHandler`

handleChunk

public void handleChunk (ClientImpl client, 
                int type, 
                ByteBuffer data, 
                boolean isReply, 
                int msgId)

處理傳入的區塊。資料 (區塊類型為「type」) 會從「data」的開頭開始，並持續到 data.limit()。

如果設定了「isReply」，則「msgId」會是我們傳送給用戶端的請求 ID。否則，就是用戶端為這個事件產生的 ID。請注意，回覆封包中可能包含我們未註冊的區塊。

處理常式不得修改「data」的內容。

參數
`client`	`ClientImpl`
`type`	`int`
`data`	`ByteBuffer`
`isReply`	`boolean`
`msgId`	`int`

`view`	`String`

invokeMethod

                Object... args)

參數
`client`	`ClientImpl`
`viewRoot`	`String`
`view`	`String`
`method`	`String`
`args`	`Object`

profileView

                String viewRoot, 
                String view,
