Android在線熱更新hot fix - AndFix試用

原理

  • 方法替換
  • principle.png
  • bug fix process

run demo

  • 具體步驟參考開源庫地址
  • 注意，執行apkpatch.bat -f 3.apk -t 1.apk -o output -k xx.keystore -p xxx-a yy -e xxx生成的是一個目錄，我們用到的是目錄裏面的xxx.apatch，將這個apatch推到手機即可
  • 測試工程，主要用於代碼學習，在native和java層加了log，地址https://github.com/cheyiliu/test4XXX/tree/master/test4AndFix-master

測試

  • 測試1，新增方法和修改方法均可hot fix
  • 測試2，新增類並調用，不可行，app異常退出
  • 測試3，在測試1的基礎上，刪除掉patch後重啓app或者重啓手機再起app，fix依然有效，框架留有緩存(/data/data/com.euler.andfix/files)

實現

  • 類圖
    class_diagram

  • 序列圖
    SequenceDiagram
