Question

我正在应用程序中设置一个当前位置。但是它崩溃了

在com.example.webforest.quickaidlikeuber2nd.CustomerMapActivity.getDriversAround（CustomerMapActivity.java:577）

val rawJson: String = """xxx{"a": "x", "b": "y", "c": "z"}""" // invalid JSON
val rawJson: String = """[1,2,3]""" // not a JSON object
val rawJson: String = """{"a": 1, "b": "y", "c": "z"}""" // not all values are string

at com.example.webforest.quickaidlikeuber2nd.CustomerMapActivity.access $ 2300（CustomerMapActivity.java:76）

async def get_cells(websocket):
    async for message in websocket:
        ...

async def get_shaded_area(websocket):
    async for message in websocket:
        ...

async def router(websocket, path):
    if path == "/":
        await get_cells(websocket, path)
    elif path == "/shade-area":
        await get_shaded_area(websocket, path)

asyncio.get_event_loop().run_until_complete(
    websockets.serve(router, 'localhost', 8765))

asyncio.get_event_loop().run_forever()

在com.example.webforest.quickaidlikeuber2nd.CustomerMapActivity $ 10.onLocationResult（CustomerMapActivity.java:512）中说

 boolean getDriversAroundStarted = false;
List<Marker> markers = new ArrayList<Marker>();
private void getDriversAround(){
    getDriversAroundStarted = true;
    DatabaseReference driverLocation = FirebaseDatabase.getInstance().getReference().child("driversAvailable");

    GeoFire geoFire = new GeoFire(driverLocation);
    GeoQuery geoQuery = geoFire.queryAtLocation(new GeoLocation(mLastLocation.getLongitude(), mLastLocation.getLatitude()), 999999999);

Answer 1

请查看其source codes：

if (!GeoLocation.coordinatesValid(latitude, longitude)) {
    throw new IllegalArgumentException("Not a valid geo location: " + latitude + ", " + longitude);
}

public static boolean coordinatesValid(double latitude, double longitude) {
    return latitude >= -90 && latitude <= 90 && longitude >= -180 && longitude <= 180;
}

通知-118.2541117不在允许的范围内。

Answer 2

看来您的经纬度顺序错误。

错误消息Not a valid geo location: -118.2541117, 33.985805显示纬度，后跟经度。 -118度的纬度没有意义。纬度值必须在-90到+90度之间。

请告诉我如何解决这个问题。

仔细检查您的代码，看看在哪里改变了纬度和经度。

看起来可能可能在这里：

  GeoQuery geoQuery = geoFire.queryAtLocation(
          new GeoLocation(mLastLocation.getLongitude(),
                          mLastLocation.getLatitude()), 999999999);

您可以使用调试器进行验证。
