我正在尝试使用 Platfrom 通道集成第三方原生 SDK（用 java 编写）来颤振。现在第三方 sdk 可以完美地在原生编码中工作（没有颤动）。

但是，当我尝试使用平台通道启动意图时，应用程序只会在按钮单击时停止并显示此错误日志。

这是我的本机 UI 代码：

class NativeView implements PlatformView{
    private  Button button;

    NativeView(Context context, int id, Map<String, Object> creationParams) {
        button = new Button(context);

        button.setText("Update");
        button.setTextSize(20);

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                start_service(v);
            }
        });
    }

    public Boolean start_service(View view){
//        Log.d("NATIVE","Method called");
//        return true;
        Intent intent = new Intent(view.getContext(),com.xxx.xxx.xxx.class);
        intent.putExtra("MY-TOKEN","mytoken");
        intent.putExtra("CLIENT","xxx-xxxx");
        intent.putExtra("ENV","test");
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        view.getContext().startActivity(intent);
        return true;
    }


    @Override
    public View getView() {
        return button;
    }

    @Override
    public void dispose() {}
}

这是我的 main.dart 代码


void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) => MaterialApp( home: Native() );
}

class Native extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(),
      body: Column(
        mainAxisAlignment: MainAxisAlignment.center,
        children: <Widget>[
          Expanded( child: AndroidView(viewType: "view1",) ),
        ],
      ),
    );
  }
}

这是 mainactivity.java 文件

package com.example.platform_view_java;

import androidx.annotation.NonNull;

import io.flutter.embedding.android.FlutterActivity;
import io.flutter.embedding.engine.FlutterEngine;

public class MainActivity extends FlutterActivity {
    @Override
    public void configureFlutterEngine(@NonNull @org.jetbrains.annotations.NotNull FlutterEngine flutterEngine) {
        super.configureFlutterEngine(flutterEngine);
        flutterEngine
                .getPlatformViewsController()
                .getRegistry()
                .registerViewFactory("view1", new NativeViewFactory());


    }
}

最后是我的 nativeviewfactory.java

package com.example.platform_view_java;

import android.content.Context;
import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import java.util.Map;
import io.flutter.plugin.common.StandardMessageCodec;
import io.flutter.plugin.platform.PlatformView;
import io.flutter.plugin.platform.PlatformViewFactory;

class NativeViewFactory extends PlatformViewFactory {

    NativeViewFactory() {
        super(StandardMessageCodec.INSTANCE);
    }

    @Override
    public PlatformView create(@NonNull Context context, int id, @Nullable Object args) {
        final Map<String, Object> creationParams = (Map<String, Object>) args;
        return new NativeView(context, id, creationParams);
    }
}

我究竟做错了什么？提前致谢。
