複製程式碼
需要注意的是在得到packageInfo後必須要設定applicationInfo的sourceDir和publicSourceDir,否則你在讀取label的時候會輸出如下錯誤資訊並丟擲異常
Failure retrieving text 0x7f050000 in package com.taskkiller.demo
你讀icon的時候會輸出如下錯誤資訊並丟擲異常
Failure retrieving icon 0x7f020005 in package com.sample.radio
這是因為label和icon都是在資源裡面的,不設定sourceDir和publicSourceDir就不能讀取資源裡面的資訊
