要使用的 Android 位置管理器权限

Question

我的android项目中有以下代码:

locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
Criteria criteria = new Criteria();
bestProvider = locationManager.getBestProvider(criteria, false);
Location currentLocation = locationManager.getLastKnownLocation(bestProvider);
location = currentLocation.getLatitude() + " " + currentLocation.getLongitude();
MyLocation.setText(location);

我收到一个 provider == null 错误。我需要使用什么权限？

我的 android list 文件是:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.DuckTag"
  android:versionCode="1"
  android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".DuckTagActivity"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

</application>
</manifest>

谢谢

Answer 1

这是您需要添加到 list 文件中的内容

基于 GPS 的位置

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

---

基于网络的位置

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

以前的发贴者是错误的，如果你想同时使用两者，那么只需要ACCESS_FINE_LOCATION，详见此处:http://developer.android.com/guide/topics/location/obtaining-user-location.html

Note: If you are using both NETWORK_PROVIDER and GPS_PROVIDER, then you need to request only the ACCESS_FINE_LOCATION permission, because it includes permission for both providers. (Permission for ACCESS_COARSE_LOCATION includes permission only for NETWORK_PROVIDER.
