java缺少FusedLocationClient所需的权限

Question

我正在开发一个应用程序，从手机上获取GPS位置。我已经在XML中添加了ACCESS\u COURSE\u LOCATION的权限，但它仍然表示我需要该权限，即使该权限已经存在于XML中

这是我的密码：

import 安卓.os.Bundle;
import 安卓.support.v7.app.AppCompatActivity;
import 安卓.location.Location;

import com.google.安卓.gms.location.FusedLocationProviderClient;
import com.google.安卓.gms.location.LocationServices;
import com.google.安卓.gms.tasks.OnSuccessListener;


public final class MainActivity extends AppCompatActivity {
    public static final String TAG = "Kindness";

    private FusedLocationProviderClient mFusedLocationClient;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mFusedLocationClient = LocationServices.getFusedLocationProviderClient(
                this);

        mFusedLocationClient.getLastLocation().addOnSuccessListener(this,
                new OnSuccessListener<Location>() {
                    @Override
                    public void onSuccess(Location location) {
                        if (location != null) {

                        }
                    }
                });
    }


}

下面是XML：

<?xml version="1.0" encoding="utf-8"?>
<manifest
    xmlns:安卓="http://schemas.安卓.com/apk/res/安卓"
    package="edu.byui.cit.kindness">

    <uses-permission 安卓:name="安卓.permisison.ACCESS_COARSE_LOCATION"/>
    <uses-permission 安卓:name="安卓.permission.INTERNET"/>

    <application
        安卓:allowBackup="true"
        安卓:icon="@mipmap/ic_launcher"
        安卓:label="@string/appName"
        安卓:roundIcon="@mipmap/ic_launcher_round"
        安卓:supportsRtl="true"
        安卓:theme="@style/AppTheme">
        <activity 安卓:name="edu.byui.cit.kindness.MainActivity">
            <intent-filter>
                <action 安卓:name="安卓.intent.action.MAIN"/>

                <category 安卓:name="安卓.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>

</manifest>

这可能是因为位置权限are considered "dangerous" permissions by Android，并且当应用程序的目标SDK为23或更大时，您需要在运行时请求“危险”权限。仅仅将它们添加到清单中是不起作用的

ActivityCompat.requestPermissions(this,
                arrayOf(Manifest.permission.ACCESS_COARSE_LOCATION),
                REQUEST_CODE);
