java.lang.SecurityException“gps”位置提供程序需要ACCESS_FINE_LOCATION权限

Question

所以这是我的MyLocationListener类

package com.example.gpslocater;

import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.os.Bundle;
import android.widget.TextView;
import android.widget.Toast;

public class MyLocationListener implements LocationListener {

        public TextView mLocationTextView;
    Context mContent;
    public MyLocationListener(Context context) {
        mContent = context;
    }
    @Override
    public void onLocationChanged(Location location) {

        location.getLatitude();
        location.getLongitude();

        String Text = "My current location is :" + 
        "Latitude = " + location.getLatitude() +
        " Longitude = " + location.getLongitude();
        //figure out a way to make it display through a text view
        mLocationTextView.setText(Text);
    }

    @Override
    public void onProviderDisabled(String provider) {
        Toast.makeText(mContent, "Gps Disabled", Toast.LENGTH_SHORT).show();

    }

    @Override
    public void onProviderEnabled(String provider) {
        Toast.makeText(mContent, "Gps Enabled", Toast.LENGTH_SHORT);


    }

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

    }

}

这是我的GPS活动课程

public class GPSActivity extends Activity {
    private Button mGPSButton;
    private TextView mLatitudeTextView;
    private TextView mLongitudeTextView;
    private LocationManager mLocationManager;
    private LocationListener mLocationListener;

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

        mLocationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
        mLocationListener = new MyLocationListener(null);
        mGPSButton = (Button)findViewById(R.id.press_button);
        mGPSButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, mLocationListener);
            }
        });
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.g, menu);
        return true;
    }

}

现在，当我运行它时，它可以正常工作但按下按钮后程序停止响应会出现很多错误消息

有一条错误消息说java.lang.SecurityException“gps”位置提供程序需要ACCESS_FINE_LOCATION权限，我是否必须添加，如果是这样，我在哪里添加它？我认为这是我的程序崩溃的原因。

Answer 1

从提供的logcat有意义。 在清单中添加此内容

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

Answer 2

您必须将以下权限添加到Android清单：

<强>的AndroidManifest.xml

...

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

...

您还可以使用Eclipse的权限编辑器。

Answer 3

在清单文件中添加以下权限

 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>// missing in manifest file

Answer 4

把它放在你的清单中..权限

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

Answer 5

你是否正确需要使用许可

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