位置基於Android的應用程序錯誤

當我運行程序的時候，給消息不幸的是LOCA已停止和關閉應用程序位置基於Android的應用程序錯誤

Java編碼

package com.example.loca; 

import android.location.Location; 
import android.location.LocationListener; 
import android.location.LocationManager; 
import android.os.Bundle; 
import android.app.Activity; 
import android.content.Context; 
import android.view.Menu; 
import android.widget.TextView; 
import android.widget.Toast; 

public class MainActivity extends Activity implements LocationListener { 

    protected LocationManager locationManager; 
    protected LocationListener locationListener; 
    protected Context context; 

    TextView txtLat; 
    String lat, place1, currentlocation, btn_text; 
    String provider; 
    protected String latitude,longitude; 
    protected boolean gps_enabled,network_enabled; 



    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 


     locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 
     locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this); 

     Toast.makeText(getApplicationContext(), currentlocation , Toast.LENGTH_LONG).show(); 




    } 



    @Override 
    public void onLocationChanged(Location location) { 

     Toast.makeText(getApplicationContext(), currentlocation , Toast.LENGTH_LONG).show(); 
     // TODO Auto-generated method stub 

    } 



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

    } 



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

    } 



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

    } 



}

和logcat的是

您需要請求FINE_LOCATION權限，就像例外說的那樣。

你logcat中明確表示

產生的原因：java.lang.SecurityException異常：「GPS」的位置信息提供需要ACCESS_FINE_LOCATION許可。 1月5日至14日：20：39.230： E/AndroidRuntime（1177）：

您需要在您的manifest.xml文件

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

日誌添加下面permission說，這一切：

location provider requires ACCESS_FINE_LOCATION permission.

在AndroidManifest.xml中添加此權限，您的應用將正常工作。
