问题描述

我正在尝试将 ionic 3 应用清单中的 allowBackup 属性设置为 false，但 gradle 抱怨以下错误:

I’m trying to set the allowBackup attribute in my ionic 3 app manifest to false but gradle complains with the following error:

来自 AndroidManifest.xml:4:18-45 的属性 application@allowBackup value=(false) 也存在于 [:barcodescanner:] AndroidManifest.xml:12:9-35 value=(true).建议:添加 'tools:replace="android:allowBackup"'将 AndroidManifest.xml:4:5-11:19 处的元素覆盖.

Attribute application@allowBackup value=(false) from AndroidManifest.xml:4:18-45 is also present at [:barcodescanner:] AndroidManifest.xml:12:9-35 value=(true). Suggestion: add 'tools:replace="android:allowBackup"' to element at AndroidManifest.xml:4:5-11:19 to override.

使用 config.xml 文件中的以下行设置 allowBackup=false

To Set allowBackup=false using below line in config.xml file

<platform name="android"> <edit-config file="AndroidManifest.xml" target="/manifest/application" mode="merge"> <application android:allowBackup="false"/> </edit-config> </platform>

我在我的 ionic 3 应用程序中使用条形码扫描仪.(回购:https://github.com/phonegap/phonegap-plugin-barcodescanner 在 https://ionicframework.com/中推荐docs/native/barcode-scanner/)

I use Barcode Scanner in my ionic 3 app.(Repo: https://github.com/phonegap/phonegap-plugin-barcodescanner recommended in https://ionicframework.com/docs/native/barcode-scanner/)

请帮助我.谢谢！

推荐答案

你必须告诉编译器忽略来自外部库的属性.这样做的方法是在应用程序标签中添加这一行:

You have to tell the compiler to ignore the attribute from the external library. The way to do that is to add this line in application tag:

tools:replace="android:allowBackup"

PS:要访问这些工具，请在顶部的清单标记中添加 xmlns:tools="http://schemas.android.com/tools".

PS: To access the tools add xmlns:tools="http://schemas.android.com/tools" in the manifest tag at the top.
