这是 AndroidManifest.xml

    package="com.example.myapp">
   <application
        android:label="myapp"

我尝试使用它来显示它

class _MyHomePageState extends State<MyHomePage> 
 
  Completer<GoogleMapController> _controller = Completer();



static const LatLng _center = const LatLng(45.521563, -122.677433);
 void _onMapCreated(GoogleMapController controller) 

_controller.complete(controller);





  @override
  Widget build(BuildContext context) 
    // This method is rerun every time setState is called, for instance as done
    // by the _incrementCounter method above.
    //
    // The Flutter framework has been optimized to make rerunning build methods
    // fast, so that you can just rebuild anything that needs updating rather
    // than having to individually change instances of widgets.
    return Scaffold(

         appBar: AppBar(

           title: Text('Maps Sample App'),

           backgroundColor: Colors.green[700],

           ),

           body: GoogleMap(

             onMapCreated: _onMapCreated,

             initialCameraPosition: CameraPosition(

               target: _center,

               zoom: 11.0,

          ),

        ),

      );
  

我在 AndroidManifest.xml 中添加了<uses-library android:name="org.apache.http.legacy" android:required="false"/>，但应用程序仍然崩溃。有人可以帮帮我吗？

【问题讨论】：

我正在使用google_maps_flutter: ^1.0.6。谢谢

可能与这个github.com/flutter/flutter/issues/72185（？）有关

谢谢我去看看

【参考方案1】：

如果您在 build.gradle 中将 minSdkVersion 更改为 24，它会起作用。 还没有找到原因。

顺便说一句，即使 minSdkVersion 为 16，它也可以在 java/android studio 中运行。

所以这可能是一个颤振配置问题。

我将 minSdkVersion 更改为 24，但它仍然崩溃

【参考方案2】：

尝试 Gradle 版本 3.5.0 和最小 SDK 20

为我工作
