混得当前的位置空对三星Galaxy Android的大？

问题描述

我尝试运行我对三星Galaxy大，但它的应用没有显示我的当前位置。

 的LocationManager =（的LocationManager）getSystemService（Context.LOCATION_SERVICE）;    //创建一个标准的对象来检索提供商
    标准标准=新标准（）;    //获得最佳供应商的名称
    字符串提供商= locationManager.getBestProvider（标准，真正的）;    的System.out.println（提供者=＆gt;中+供应商）;    //获取当前位置
    地点= locationManager.getLastKnownLocation（供应商）;
    的System.out.println（所在地+位置）;
 

但始终这行返回NULL locationManager.getLastKnownLocation（供应商）; ，但这个程序正常工作在其他手机一样的索尼和LG电子

我有尝试这么多的链接，但还是同样的问题。

getLastKnownLocation()始终返回null，所有的提供者DummyLocationProvider

Android LocationManager.getLastKnownLocation（）返回null

Network供应商和供应商GPS返回空值

检查this答案，简称

要编程启动您的当前位置运行以下code你打电话之前应用 getLastKnownLocation

  YO​​UR_APPLICATION_CONTEXT.getLocationManager（）。requestLocationUpdates（
LocationManager.NETWORK_PROVIDER，0，0，新LocationListener的（）{
    @覆盖
    公共无效onStatusChanged（字符串提供商，INT地位，捆绑演员）{
    }
    @覆盖
    公共无效onProviderEnabled（字符串提供商）{
    }
    @覆盖
    公共无效onProviderDisabled（字符串提供商）{
    }
    @覆盖
    公共无效onLocationChanged（决赛地点）{
    }
}）;
 

固定GPSTracker问题的一些建议可能是，将其设置为1分钟1米

 私有静态最后长MIN_DISTANCE_CHANGE_FOR_UPDATES = 1;
私有静态最后长MIN_TIME_BW_UPDATES = 1000 * 60;
 

I'm try to run my app on Samsung Galaxy Grand but its not showing my current location.

    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

    // Creating a criteria object to retrieve provider
    Criteria criteria = new Criteria();

    // Getting the name of the best provider
    String provider = locationManager.getBestProvider(criteria, true);

    System.out.println("provider => " + provider);

    // Getting Current Location
    Location location = locationManager.getLastKnownLocation(provider);
    System.out.println("location  " + location);

but always this line return null locationManager.getLastKnownLocation(provider); but this app works fine in other phones like sony and lg.

i have try so many link but still same problem.

getLastKnownLocation() always returning null, all providers are DummyLocationProvider

Android LocationManager.getLastKnownLocation() returns null

Network provider and GPS provider returning null values

permission

<permission
    android:name="xx.xxx.xxx.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />

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

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


<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true" />

解决方案

Check this for the answer, for short

To programmatically kick start your app for "current location" run the following code before you call getLastKnownLocation

YOUR_APPLICATION_CONTEXT.getLocationManager().requestLocationUpdates(
LocationManager.NETWORK_PROVIDER, 0, 0, new LocationListener() {
    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {
    }
    @Override
    public void onProviderEnabled(String provider) {
    }
    @Override
    public void onProviderDisabled(String provider) {
    }
    @Override
    public void onLocationChanged(final Location location) {
    }
});

Some recommendations for fixing GPSTracker issues may be, to set it as 1 min 1 meter

private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 1;
private static final long MIN_TIME_BW_UPDATES = 1000 * 60 ;
