FusedLocationProviderApi 致命异常：GoogleApiClient 尚未连接。

Question

我是新手 android 开发人员。我想制作一些 Google 地图应用程序，它将显示用户当前位置周围的一些位置。但我还没有捕获用户位置。我看了太多文档，Google来自 Google 的地图教程。从 Whosebug 搜索，但我找不到任何解决方案。

有我的HaritaFragment.java

问题是什么？我用 GooglePlayServices.

尝试了 4.0.1 真正的 HTC 设备和 4.4.4 GenyMotion

我想让用户靠近 Parse.com 的位置，我必须为此方法捕获用户位置：

if (userLocation != null) {

            ParseGeoPoint parsedLocation = (new ParseGeoPoint(userLocation.getLatitude(), userLocation.getLongitude()));
            ParseQuery<ParseObject> query = ParseQuery.getQuery("Vets");
            query.fromLocalDatastore();
            query.whereNear("location", parsedLocation);
            //query.whereWithinKilometers("location",userLocation,100);
            query.setLimit(250);
            query.findInBackground(new FindCallback<ParseObject>() {
                @Override
                public void done(List<ParseObject> list, ParseException e) {

                    if (e == null) {



                    } else {

                        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
                        builder.setTitle(getString(R.string.parse_online_query_error_title));
                        builder.setMessage(getString(R.string.parse_online_query_error_message));
                        builder.setPositiveButton(android.R.string.ok, null);
                        AlertDialog dialog = builder.create();
                        dialog.show();
                    }
                }
            });
        }

如果你告诉我另一种方法来做到这一点。这对我有好处。我不会坚持 FusedLocationProviderApi.

谢谢！

Answer 1

看起来你刚刚弄错了顺序。了解开始、暂停和恢复活动时的顺序 Android 很重要。

http://developer.android.com/training/basics/activity-lifecycle/pausing.html

您的代码中的问题是当您点击 onResume 时 mGoogleApiClient 可能没有完全连接。

这是你应该有的顺序

创建 mGoogleApi客户端
调用mGoogleApiClient.connect();
onConnected() 被自动调用。

-- 从 onConnected

内部调用 startLocationUpdates()

执行上述操作意味着您的 Api 客户端在您请求位置更新时始终处于连接状态。

我认为修复代码的最快方法是删除 onPause 和 onResume 方法并取消注释 onStop 中的 onDisconnect。

允许 onStart 和 onStop 处理您的连接，然后该连接依次处理位置更新。

祝你好运。
