Flutter 运行报错 Attribute application@label value=(XXX) from AndroidManifest.xml

前言

最近想搞个flutter 项目，本人初学，在启动flutter时，报了以下错误

D:\developSoftware\flutter\workspace\chat_flutter\android\app\src\debug\AndroidManifest.xml:4:9-37 Error:
Attribute application@label value=(chat_flutter) from AndroidManifest.xml:4:9-37
is also present at [com.tencent.imsdk:imsdk:4.9.6] AndroidManifest.xml:18:9-41 value=(@string/app_name).
Suggestion: add 'tools:replace="android:label"' to <application> element at AndroidManifest.xml:3:4-40:19 to override.

结局方案

错误中描述的很清楚，在application标签中添加 'tools:replace="android:label"'

可我看了我的文件中没有application标签

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.chat_flutter">
    <uses-permission android:name="android.permission.INTERNET"/>
</manifest>

于是还是去网上搜了一下，网上说直接新加applcaition标签，改造如下

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
        xmlns:tools="http://schemas.android.com/tools"
    package="com.example.chat_flutter">
    <application  tools:replace="android:label" >
    </application>
    <uses-permission android:name="android.permission.INTERNET"/>
</manifest>

但这时有报了个错误

错误时说  android:label 属性无value值

D:\developSoftware\flutter\workspace\chat_flutter\android\app\src\debug\AndroidManifest.xml:4:5-6:19 Error:
        tools:replace specified at line:4 for attribute android:label, but no new value specified
D:\developSoftware\flutter\workspace\chat_flutter\android\app\src\debug\AndroidManifest.xml Error:
        Validation failed, exiting

于是最终改造如下：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.example.chat_flutter">
    <application  tools:replace="android:label" android:label="XXXX">
    </application>
    <uses-permission android:name="android.permission.INTERNET"/>
</manifest>
