我不能在android中使用locationServices.getLastLocation

Question

我正在尝试在我的安卓应用程序中获取最后一个位置。这是通过我的应用程序中的mapbox的帮助来完成的。但是我无法导入"import com.mapbox.mapboxsdk.location.LocationServices;">

apply plugin: 'com.android.application'

依赖关系 { 编译组： 'com.mapbox.mapboxsdk'， 名称： 'mapbox-android-navigation'， 版本： '0.1.0'

compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'
compile('com.mapbox.mapboxsdk:mapbox-android-sdk:3.2.0@aar') {
    transitive = true
}
compile ('com.mapbox.mapboxsdk:mapbox-android-directions:1.0.0@aar'){
    transitive=true
}
compile 'com.google.android.gms:play-services:10.2.1'
compile 'com.squareup.retrofit2:retrofit:2.2.0'
compile 'com.squareup.retrofit2:converter-gson:2.2.0'
compile ('com.mapbox.mapboxsdk:mapbox-android-sdk:5.0.2@aar'){
    transitive=true
}
compile ('com.mapbox.mapboxsdk:mapbox-android-services:2.1.0@aar'){
    transitive=true
}
compile('com.mapbox.mapboxsdk:mapbox-android-sdk:4.0.0@aar') {
    transitive = true
}

}

我使用以下代码来获取应用程序中的最后一个位置：

public static Location getLastKnownLocation(Context context) {
    try {
        LocationManager mLocationManager = (LocationManager) context.getSystemService(LOCATION_SERVICE);
        List<String> providers = mLocationManager.getProviders(true);
        Location bestLocation = null;
        for (String provider : providers) {
            Location l = mLocationManager.getLastKnownLocation(provider);
            if (l == null) {
                continue;
            }
            if (bestLocation == null || l.getAccuracy() < bestLocation.getAccuracy()) {
                // Found best last known location: %s", l);
                bestLocation = l;
            }
        }
        return bestLocation;
    } catch (SecurityException e) {
        e.printStackTrace();
        return null;
    }
}

这段代码仍然需要改进：最好请求权限而不是捕获安全异常：查看此堆栈溢出线程

不要忘记在清单上添加所需的权限：

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