Question

当我运行应用程序时，它会发送消息，遗憾的是loca已停止并关闭应用程序

Java编码

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

    }



}

AND LOGCAT

Answer 1

您需要请求FINE_LOCATION权限，就像例外情况一样。

Answer 2

你的logcat清楚地说了

引起：java.lang.SecurityException：＆＃34; gps＆＃34;位置提供者需要ACCESS_FINE_LOCATION权限。 05-14 01：20：39.230： E / AndroidRuntime（1177）：

您需要在permission文件

中添加以下manifest.xml

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

Answer 3

日志说明了一切：

 location provider requires ACCESS_FINE_LOCATION permission.

在AndroidManifest.xml中添加此权限，您的应用程序将正常运行。

基于位置的Android应用程序错误
