问题 We can detect code using gps, i want to detect location via wifi ??? how can i do that ? i want two threads simulataniously running one detecting locaiton using GPS another detecting using WIFI. 回答1: Check out this link and "public static final String NETWORK_PROVIDER " on that page. Also I think this open source project uses both gps and network location: Link . Hopefully a good example. 回答2: public class FastMainActivity extends Activity { Button searchBtn = null; Intent locatorService =

Android 2.3 emulator crashes when updating location

大憨熊 提交于 2019-12-09 18:01:19
问题 I am using Eclipse to write and debug an Android application. One of the things I need to do is to update the location of the device, and so I have tried to use the Location Controls panel in the Emulator control window. On the Manual tab, I select Decimal, enter a valid latitude and longitude, and then click Send. Unfortunately, what happens next is that the emulator crashes (logcat output below). Is this a known issue, and if so, is there a workaround? Thanks for any help, Martin 02-13 08

RuntimeException in Gson parsing JSON: Failed to invoke protected java.lang.ClassLoader() with no args

问题 I've inherited some code that saves our application state as JSON using Gson, and then reads it using fromJson. Gson gson = createGson(); gson.fromJson(objString, myClass); One of the fields being saved is a Location. Unfortunately, very occasionally the parsing of that saved data fails because my saved Location includes an mClassLoader in its mExtras, and the Gson library fails to create the ClassLoader with this error: RuntimeException: Failed to invoke protected java.lang.ClassLoader()

check if a user allows the app to use their location

拈花ヽ惹草 提交于 2019-12-09 16:43:19
问题 The first time the app tries to get the users location they are prompted with "Would like to use your current location" and they can hit Don't allow or ok. Is there any way to find out if the user has hit ok or don't allow? I'm trying to have the MKMapView show the users current location but I would like to take different actions based on the users selection. Normally you would think there would be a delegate to get this information but there doesn't seem to be. Thanks in advance for your

window.location 可以简写成location。location相当于浏览器地址栏,可以将url解析成独立的片段。 一、属性 1 console.log(location.host);//主机名,包括端口 2 console(location.hostname);//主机名 3 console.log(location.href); //完整的url(网址) 4 console.log(location.pathname); //文件名(url中的部分路径) 5 console.log(location.port); //端口号 6 console.log(location.protocol); //协议(HTTP、https) 7 console.log(location.search) //提交的text(查询字符串) 二、location 每个查询字符串参数获取方法 1、一个地址 1 HTML、CSS、JS文件代码/BOM代码文件/04 location对象的常用属性.html?user=aaa&pwd=123 2 3 //?user=aaa&pwd=123 2、取得去掉问号的查询字符串 1 var qs = location.search.length > 0? location.search.substring(1) : '';//user=aaa&pwd

Is the new 'Cloud Firestore' able to query based location distance?

若如初见. 提交于 2019-12-09 16:01:21
问题 I know Cloud Firestore stores locations based on latitude and longitude in Geopoints . However, I can't find a method or a way documented to query documents based on the distance to a certain point, kind of what GeoFire does for the Realtime database. Is there a way to achieve that? 回答1: It's something we're looking into, but isn't supported at this time. 来源: https://stackoverflow.com/questions/46579698/is-the-new-cloud-firestore-able-to-query-based-location-distance

Location getAccuracy() what this function do?

五迷三道 提交于 2019-12-09 08:18:43
问题 I know that this function returns a float indicating the accuracy of a particular location. My question is: Is it right that greater the value returned by this function means more accurate the location is? Or it is the inverse what I am saying ? 回答1: The lower the number, the more accurate it is. 回答2: getAccuracy() describes the deviation in meters. So, the smaller the number, the better the accuracy. 回答3: Accuracy reported by getAccuracy() is in meters, ex. 10 meters. Google defines accuracy
