Android Studio 項目在更改 package 名稱后無法啟動活動

[英]Android Studio project unable to start activity after changing the package name

問題描述

這是我在更改項目的 package 名稱后遇到的錯誤

我已經重構了與之前的 package 名稱相關的所有內容。

僅供參考，我使用 android 工作室中的重構選項更改了 package 名稱

上面的這條線指向這條線

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home); <========== HERE

我已經嘗試解決的問題：

  • 清理並重建項目
  • 使緩存無效並重新啟動
  • 檢查對舊 package 名稱的所有引用

沒有實例化的activity_home

還要在導入部分更改 R 文件的路徑。

解決方案2

參考這些日志行：

...
Binary XML file line #15: Binary XML file line #10: Error inflating class fragment
...
Caused by: androidx.fragment.app.Fragment$InstantiationException: Unable to instantiate fragment com.nectardigit.eshopping.user.ui.home.HomeFragment: make sure class name exists
...

嘗試檢查您的 xml 文件R.layout.activity_home 。
