android – 呼叫需要用户拒绝的权限

我试图使一个应用程序每五分钟后发送一个用户的位置更新.我想我的代码工作正常,但是我收到一个关于应用程序正在使用的权限的错误.我确信我已经在清单文件中添加了权限.有人可以告诉我有什么问题吗？这是我的代码

MainActivity.java

LocationManager locationManager ;
String provider;

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

    // Getting LocationManager object
    locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);

    // Creating an empty criteria object
    Criteria criteria = new Criteria();

    // Getting the name of the provider that meets the criteria
    provider = locationManager.getBestProvider(criteria,false);

    if(provider!=null && !provider.equals("")){

        // Get the location from the given provider
        Location location = locationManager.getLastKnownLocation(provider);
        locationManager.requestLocationUpdates(provider,5*60*1000,this);

        if(location!=null)
            onLocationChanged(location);
        else
            Toast.makeText(getBaseContext(),"Location can't be retrieved",Toast.LENGTH_SHORT).show();

    }else{
        Toast.makeText(getBaseContext(),"No Provider Found",Toast.LENGTH_SHORT).show();
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main,menu);
    return true;
}

@Override
public void onLocationChanged(Location location) {
    // Getting reference to TextView tv_longitude
    TextView tvLongitude = (TextView)findViewById(R.id.tv_longitude);

    // Getting reference to TextView tv_latitude
    TextView tvLatitude = (TextView)findViewById(R.id.tv_latitude);

    // Setting Current Longitude
    tvLongitude.setText("Longitude:" + location.getLongitude());

    // Setting Current Latitude
    tvLatitude.setText("Latitude:" + location.getLatitude() );
}

@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
}

}

我收到一个错误,因为呼叫需要许可,用户可能会拒绝这些行 –

Location location = locationManager.getLastKnownLocation(provider);
        locationManager.requestLocationUpdates(provider,this);

我的AndroidManifest就是这样

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

<application
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/title_activity_main" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

解决方法

你使用哪个SDK？
如果您使用棉花糖,则需要检查用户是否已经为每个位置呼叫授予权限.

看看Here.

你应该这样做：

if ( ContextCompat.checkSelfPermission( this,android.Manifest.permission.ACCESS_COARSE_LOCATION ) != PackageManager.PERMISSION_GRANTED ) {

            ActivityCompat.requestPermissions( this,new String[] {  android.Manifest.permission.ACCESS_COARSE_LOCATION  },LocationService.MY_PERMISSION_ACCESS_COURSE_LOCATION );
        }

如果你没有它,请求许可.
