Question

我尝试使用Google地图API开发Android地图应用程序。

使用Google API在多个emulatet Android设备（2.1; 2.3.3; 4.0.3）上进行测试。

问题是logcat将此抛给我：

以下是代码：

package map.test.activity;

import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;

import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;

public class MapTestActivity extends MapActivity {

    private MapController mapController;
    private MapView mapView;
    private LocationManager locationManager;

    public void onCreate(Bundle bundle) {
        super.onCreate(bundle);
        setContentView(R.layout.main); // bind the layout to the activity

        mapView = (MapView) findViewById(R.id.mapview);
        mapView.setBuiltInZoomControls(true);
        mapController = mapView.getController();
        mapController.setZoom(10); // Zoom 1 is world view
        locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
                        0, new GeoUpdateHandler());
    } //public void 

    @Override
    protected boolean isRouteDisplayed() {
        return false;
    }// protected boolean

    public class GeoUpdateHandler implements LocationListener {

            public void onLocationChanged(Location location) {
                    int lat = (int) (location.getLatitude() * 1E6);
                    int lng = (int) (location.getLongitude() * 1E6);
                    GeoPoint point = new GeoPoint(lat, lng);
                    mapController.animateTo(point);
            }

            public void onProviderDisabled(String provider) {
                // TODO Auto-generated method stub

            }

            public void onProviderEnabled(String provider) {
                // TODO Auto-generated method stub

            }

            public void onStatusChanged(String provider, int status,
                    Bundle extras) {
                // TODO Auto-generated method stub

            }
    }

} //public class MapTestActivity

和Manifest：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="map.test.activity" android:versionCode="1"
    android:versionName="1.0">

    <uses-permission android:name="android.permission.INTERNET"></uses-permission>
    <uses-permission android:name="android.permission.ACCES_COARSE_LOCATION"></uses-permission>
    <uses-permission android:name="android.permission.ACCES_FINE_LOCATION"></uses-permission>

    <uses-sdk android:minSdkVersion="10" /> 

    <application android:icon="@drawable/ic_launcher" android:label="@string/app_name">
        <activity android:name=".MapTestActivity" android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <uses-library android:required="true" android:name="com.google.android.maps" />
    </application>
</manifest>

我已经尝试转移权限的位置并将编译器设置为JAVA 1.6（并将@Override添加到最后三个公共空间）。它可能是非常明显的东西，但我刚开始用Java开发。

Answer 1

你拼错了

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

应该是

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

Answer 2

确保uses-permission元素不在application元素中。我不小心将它粘贴在那里，Android Studio并没有告诉你这是一个问题。一旦我把它移出，就解决了这个问题。

示例：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.android.someapp.app" >

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

  <application ...>

...

Answer 3

我收到了与您相同的错误消息，但在我的情况下，原来是因为我只使用了

permission

而不是

uses-permission

希望这可以节省一个下午的调试时间; - ）

Answer 4

你做的很蠢。您不得从"@Override方法的上一行中删除OnCreate()“。添加该行并尝试重新运行您的代码。

java.lang.SecurityException：Provider gps需要ACCESS_FINE_LOCATION权限
