flutter: geolocator不起作用，请确保在清单中至少定义了ACCESS_FINE_LOCATION或ACC

Question

我正在尝试使用地理定位器，我添加了两个

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

到我的AndroidManifest主包下，我得到这个错误:E/flutter (21706): [error: flutter/lib/ui/ui_dart_state.cc(177)]未处理的异常:在manifest中没有定义位置权限。确保在清单中至少定义了ACCESS_FINE_LOCATION或ACCESS_COARSE_LOCATION。我的清单:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="leora3y.co.el_joker">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<!-- io.flutter.app.FlutterApplication is an android.app.Application that
calls FlutterMain.startInitialization(this); in its onCreate method.
In most cases you can leave this as-is, but you if you want to provide
additional functionality it is fine to subclass or reimplement
FlutterApplication and put your custom class here. -->
<application
android:name="io.flutter.app.FlutterApplication"
android:label="el_joker"
android:icon="@mipmap/ic_launcher">

谢谢。

Answer 1

您可以尝试以下步骤来解决问题。

1. Sync gradle from android studio (must required step) 
2. flutter clean
3. flutter pub get
4. flutter run

Answer 2

当你向AndroidManifest添加权限或其他内容时，请确保重新运行应用程序。

Answer 3

请务必请求权限

LocationPermission permission;
permission = await Geolocator.requestPermission();

Answer 4

首先编辑你的ANDROID MANIFEST文件并添加这些

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

然后请求用户的位置权限，因为如果不请求他的权限，您将无法获取它。

LocationPermission许可;

在您创建的async函数中添加上述两行代码最后在终端

中运行这些命令

1. 颤振清洁
3. 颤振运行

你现在可以走了。
