Location request timed out on android emulator with React
I'm building my first android app with react-native. What I want to do is display my current location . But it doesn't seem to work on my emulator . Instead I get a "Location request timed out" error in the console. Here is a sample of code from my idex.android.js file:
initGeoloc() {
navigator.geolocation.getCurrentPosition(
(position) => {
console.log(JSON.stringify(position));
}
);
}
render() {
this.initGeoloc();
... some more code and the view
The code is very simple so I don't think the error comes from here. I added these permission in my AndroidManifest.xml file (ACCESS_FINE_LOCATION, ACCESS_COARSE_LOCATION):
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.myapp">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<application
android:allowBackup="true"
android:label="@string/app_name"
android:icon="@mipmap/ic_launcher"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
<uses-library android:name="com.google.android.maps" />
<meta-data android:name="com.google.android.geo.API_KEY" android:value="mykey"/>
</application>
I don't see anything wrong here either, so I think the problem comes from the Android emulator. I use Android Virtual Device Manager to create a Nexus 5, Google APIs (Google Inc.) - API Level 23 virtual device. The geolocation is activated on the device but I did not see any geolocation tool in the developper tools or configuration. So probably the error comes from here. The virtual device does'nt return any location.
How can I fix this ?
设置为enableHighAccuracy false，问题就会解决
navigator.geolocation.getCurrentPosition((position) => {
console.log(position);
}, error => console.error(error), { enableHighAccuracy: false, timeout: 20000, maximumAge: 1000 });
This question is answered in this thread. How to emulate GPS location in the Android Emulator? Sorry for the duplicate. I fixed my problem using telnet.
