Question

我正在努力获取一款可从手机获取GPS定位的应用。我已经为ACCESS_COURSE_LOCATION添加了XML的权限，但它仍然说我需要权限，即使权限已经在XML中。

这是我的代码：

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

import com.google.android.gms.location.FusedLocationProviderClient;
import com.google.android.gms.location.LocationServices;
import com.google.android.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) {

                        }
                    }
                });
    }


}

这是XML：

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

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

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

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

</manifest>

这可能是因为位置权限are considered "dangerous" permissions by Android，当您的应用程序的目标SDK为23或更高时，您需要在运行时请求“危险”权限。只是将它们添加到清单中是行不通的。

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

缺少FusedLocationClient所需的权限
