我目前正在开发一款带有电容器的Ionic应用程序。奇怪的是，apk产生了意想不到的结果。
这种情况经常发生。让我描述一下我的工作。
在构建apk时，我首先确保删除capacitor.config.json中的server密钥。它是在我使用Ionic Live Reload时写的。
然后我使用以下命令来构建apk：
-
ionic build -
ionic cap copy -
ionic cap sync -
ionic cap open android
在单击"播放"按钮在设备上安装应用程序之前，我会转到我的设置并清除应用程序的缓存和数据，然后卸载应用程序。
然后我在手机上安装了新的应用程序。但奇怪的是，内部数据库中既有旧值，也有一些旧值。
这怎么会发生？我做错了什么？
这是我的package.json:

我也遇到了同样的问题。我通过删除ionic应用程序中的android和dist文件夹解决了这个问题。然后我跑了：
npm run build
ionic capacitor add android
ionic capacitor open android’
更新：您也可以在不删除文件夹的情况下执行以下步骤：
npm run build
npx cap sync
ionic capacitor open android
(In android studio) sync project with gradle files
我发现了问题。
在Android清单中，设置android:allowBackup="false"。默认情况下为true，并且在未设置为false时将加载一些旧数据。
