React Native App 没有从 Android Emulator 获取位置

Question

First of all I'll let you know that this question solves a part of my problem but not all of it:

Emulator's Location simulation not working

I managed to have the emulator's location provider to work (verifying it using the Google Maps App) but it is my React Native app the one that is not getting the location. It does on a real device so I would say it is more of an issue between the app and the emulator.

So as I said, I'm getting this location in the Google Maps App:

My Emulator specs:

What I'm doing in my React App is the following:

In a React async action: (Works on real device)

return navigator.geolocation.getCurrentPosition(
  (position) => {
    let initialCenterPosition = {
      latitude : position.coords.latitude,
      longitude : position.coords.longitude
    }

    dispatch(requestInitialCenterPositionSuccess(initialCenterPosition))
  },
  (error) => {
    dispatch(requestInitialCenterPositionError(error))
  },
  {enableHighAccuracy: true, timeout: 10000, maximumAge: 0}
)

And the current permissions in my Android Manifest XML just in case:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

My Sdk and Build Tools versions in the build.graddle file:

compileSdkVersion 23
buildToolsVersion "23.0.3"

Also tested it with builtToolsVersion : "24.0.2"

Switching the enableHighAccuracy to false in the getCurrentPosition function won't do any change.

Is there another aspect I should be aware off in my React Native app specs so this could work? It does seem weird to me that I don't have any trouble on the real device

Thanks to all

Answer 1

设置为enableHighAccuracy false，问题就解决了

{enableHighAccuracy: false, timeout: 10000, maximumAge: 0}

Answer 2

更改位置设置后，您应该在设备中重新启动。
