[android] 没有定位结果 about amap_location_fluttify HOT 17 CLOSED

[ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: PlatformException(Attempt to invoke virtual method 'int java.lang.Integer.intValue()' on a null object reference, null, null)
换旧的版本也不行，再换回最新0.8.3+4d92ce0后，直接报这个错了

from amap_location_fluttify.

断点com_amap_api_location_AMapLocationListener的onLocationChanged一直没有回调

from amap_location_fluttify.

@JakeWoki 你先下载demo apk试下能不能正常获取定位 https://github.com/fluttify-project/amap_location_fluttify/blob/master/example/build/app/outputs/apk/release/app-release.apk?raw=true

from amap_location_fluttify.

demo apk可以获取到，直接运行demo也可以获取到

from amap_location_fluttify.

那应该就是key不对，建议多检查一下。

from amap_location_fluttify.

如果是key有问题，会提示鉴权有问题的

from amap_location_fluttify.

那我也不知道了 :)

from amap_location_fluttify.

俺也遇到这个问题, 高德地图后台 key sha1 packageName 检查过都是正确的, 控制台打印的日志也没有说是鉴权问题. 也是抛出这句 ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: PlatformException(Attempt to invoke virtual method 'int java.lang.Integer.intValue()' on a null object reference, null, null)

俺 location map search 都引用了 就地图是可以正常用, 搜索和定位 都是报上面那句, 理论上说地图可以用,证明 key是正确的了吧?

这个错可否贴一个完整一点的，具体在哪一行报的这个错？

这是我点击定位后的所有报错信息了

OK，我会抽时间看下，感谢反馈，我比较喜欢你这样的反馈，直接上能够复现问题的repo 😉

from amap_location_fluttify.

原因我查到了，跟新版android embedding有关，如果你只使用定位组件，那么可以先强制依赖foundation_fluttify为0.4.3版本试下，如果用到另外两个组件，那么可能也要降低一下版本，但是具体降到多少版本可能需要你自己试一下，这个问题我会找时间看下怎么处理。

dependencies:
  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2
  decorated_flutter: ^0.10.0
  amap_location_fluttify: ^0.8.5+107df19
  permission_handler: ^4.0.0

# 这里覆盖一下foundation_fluttify的版本
dependency_overrides:
  foundation_fluttify: 0.4.3

from amap_location_fluttify.

按上面改用定位可以了。
新版android embedding
FoundationFluttifyPlugin

override fun onAttachedToEngine(binding: FlutterPlugin.FlutterPluginBinding) {
        val plugin = FoundationFluttifyPlugin()

        gMethodChannel = MethodChannel(binding.binaryMessenger, "com.fluttify/foundation_method")
        gMethodChannel.setMethodCallHandler(plugin)

        gBroadcastEventChannel = EventChannel(binding.binaryMessenger, "com.fluttify/foundation_broadcast_event")
    }

这里应该错了，去掉 val plugin = FoundationFluttifyPlugin()
gMethodChannel.setMethodCallHandler(plugin)改成gMethodChannel.setMethodCallHandler(this)

from amap_location_fluttify.

ok，我会尽快更新一下foundation_fluttify.

from amap_location_fluttify.

foundation_fluttify 0.4.5+1版本处理了这个问题，flutter packages upgrade; flutter packages get跑一下升级一下依赖。

from amap_location_fluttify.

foundation_fluttify 0.4.5+1刚刚用了可以获取到结果了
