我正在按照https://pub.dev/packages/firebase_messaging#-readme-tab-的步骤在模拟器中显示通知,但在flutter终端中却收到此错误,
出了什么问题: 任务':app:generateDebugBuildConfig'的执行失败。 org.xml.sax.SAXParseException; systemId:文件:/ C:/Users/steve/Repos/off-top-flutter/android/app/src/main/AndroidManifest.xml; lineNumber:17; columnNumber:44;已经为元素“应用程序”指定了绑定到名称空间“ http://schemas.android.com/apk/res/android”的属性“名称”。>
下面是我在AndroidManifest.xml中的代码:
<application
android:name=".Application"
android:name="io.flutter.app.FlutterApplication"
android:label="off_top_mobile"
android:icon="@mipmap/ic_launcher">
<activity
android:name=".MainActivity"
android:launchMode="singleTop"
android:theme="@style/LaunchTheme"
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
android:hardwareAccelerated="true"
android:windowSoftInputMode="adjustResize">
<!-- This keeps the window background of the activity showing
until Flutter renders its first frame. It can be removed if
there is no splash screen (such as the default splash screen
defined in @style/LaunchTheme). -->
<meta-data
android:name="io.flutter.app.android.SplashScreenUntilFirstFrame"
android:value="true" />
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
<intent-filter>
<action android:name="FLUTTER_NOTIFICATION_CLICK" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
答案 0 :(得分:0)
您在application元素中两次指定了android:name
属性:
<application
android:name=".Application"
android:name="io.flutter.app.FlutterApplication"
您只能拥有一个。您可能只想保留刚开始的那个,而不是添加的那个。
