来自AndroidManifest.xml的属性application @ allowBackup value =(false)也出现在[:barcodescanner:] AndroidManifest.xml value =(true) [英] Attribute application@allowBackup value=(false) from AndroidManifest.xml is also present at [:barcodescanner:] AndroidManifest.xml value=(true)

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会抱怨以下错误:

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

AndroidManifest.xml:4:18-45中的属性application @ allowBackup value =(false)也出现在[:barcodescanner:] AndroidManifest.xml:12:9-35 value =(true).建议:添加"tools:replace =""android:allowBackup"覆盖AndroidManifest.xml:4:5-11:19的元素.

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ionic 3应用程序中使用了条形码扫描仪.(回购: https://github.com在 https://ionicframework.com/中推荐的/phonegap/phonegap-plugin-barcodescanner 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

您必须告诉编译器忽略外部库中的属性.这样做的方法是在应用程序标签中添加以下行:

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，请在顶部的清单标签中添加 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.
