android清单文件中的Flutter位置权限问题

Question

我的颤振代码：

 onPressed: () async {
                  Geolocator
                      .getCurrentPosition(desiredAccuracy: LocationAccuracy.best, forceAndroidLocationManager: true)
                      .then((Position position) {
                    setState(() {
                      _currentPosition = position;
                      print ( "LAT: ${_currentPosition.latitude}, LNG: ${_currentPosition.longitude}");
                    });
                  }).catchError((e) {
                    print(e);
                  });
                },

它显示以下内容：

`No location permissions are defined in the manifest. Make sure at least CCESS_FINE_LOCATION` or ACCESS_COARSE_LOCATION are defined in the manifest.

即使我已经在清单中添加了权限

 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.agent">
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
   <application
        android:label="agent"
        android:icon="@mipmap/ic_launcher">
        <activity
            android:name=".MainActivity"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize">
            <meta-data
              android:name="io.flutter.embedding.android.NormalTheme"
              android:resource="@style/NormalTheme"
              />
            <meta-data
              android:name="io.flutter.embedding.android.SplashScreenDrawable"
              android:resource="@drawable/launch_background"
              />
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />
    </application>
</manifest>

我有以下无法修复的错误：

此处不允许使用属性 android:icon 未解析的类“MainActivity”

Answer 1

desiredAccuracy：LocationAccuracy.best 两者都需要

  <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
