unity对接百度地图(显示地图和自身位置)

我是将unity工程导出为android工程,将定位脚本和需要的jar包依赖等加入,如下

            }
        });
    }

    /**

    /**

    public class MyLocationListenner  extends BDAbstractLocationListener {

        @Override
        public void onReceiveLocation(BDLocation location) {
            // MapView 销毁后不在处理新接收的位置
            if (location == null || mMapView == null) {
                return;
            }
            if (isFirstLoc) {
                LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
                MapStatusUpdate update= MapStatusUpdateFactory.newLatLng(latLng);
                mBaiduMap.animateMapStatus(update);
                isFirstLoc = false;
                MapStatus.Builder builder = new MapStatus.Builder();
                builder.target(latLng).zoom(20.0f);
                mBaiduMap.animateMapStatus(MapStatusUpdateFactory.newMapStatus(builder.build()));
                addMarker(latLng);
            }

            MyLocationData locData = new MyLocationData.Builder()
                    .accuracy(location.getRadius())// 设置定位数据的精度信息，单位：米
                    .direction(location.getDirection()) // 此处设置开发者获取到的方向信息，顺时针0-360
                    .latitude(location.getLatitude())
                    .longitude(location.getLongitude())
                    .build();
            // 设置定位数据, 只有先允许定位图层后设置数据才会生效
            mBaiduMap.setMyLocationData(locData);
        }
    }

    @Override
    protected void onResume() {
        super.onResume();
        // 在activity执行onResume时必须调用mMapView. onResume ()
        mMapView.onResume();
    }

    @Override
    protected void onPause() {
        super.onPause();
        // 在activity执行onPause时必须调用mMapView. onPause ()
        mMapView.onPause();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        bitmapA.recycle();
        // 退出时销毁定位
        mLocClient.stop();
        // 关闭定位图层
        mBaiduMap.setMyLocationEnabled(false);
        // 在activity执行onDestroy时必须调用mMapView.onDestroy()
        mMapView.onDestroy();
    }
}

因为我是unity对接,所以在UnityPlayerActivity下加入

	// 这个名字随便起的,自己根据unity方法改
	 public  void ShowToast()
    {
        startActivity(new Intent(this, LocationCustomDemo.class));
    }

DemoApplication

public class DemoApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        // 在使用 SDK 各组间之前初始化 context 信息，传入 ApplicationContext
        // 默认本地个性化地图初始化方法
        SDKInitializer.initialize(this);

        //自4.3.0起，百度地图SDK所有接口均支持百度坐标和国测局坐标，用此方法设置您使用的坐标类型.
        //包括BD09LL和GCJ02两种坐标，默认是BD09LL坐标。
        SDKInitializer.setCoordType(CoordType.BD09LL);
    }
}

因为我在LocationCustomDemo中申请权限用了AndPermission,代码不放了,可以去这里看

activity_locationcustom

AndroidManifest 有些配置是unity自带的
注意application的android:name=".BaiduMap.DemoApplication",如果不加这个会报错

不要忘了在build.gradle下加入下面这个,否则会报错

   sourceSets {
        main {
            jniLibs.srcDir 'libs'
        }
    }

还有百度地图需要的库,可以自己去官网下地图需要的库即可,这里我就不放出来了

记 : 定位定到几内亚或者地球经纬度的另一端是因为鉴权错误,确认AK和应用包名是否匹配,然后看下鉴权信息把应用的sha1码改成鉴权信息上的sha1码即可
