一.在高德官網下載需要對應的SDK  http://lbs.amap.com/api/android-location-sdk

    通過SHA1值獲取對應的key值    

   a.SHA1值得獲取:  1.在cmd中定位到 .android

     2.輸入keytool -list -v -keystore debug.keystore   口令是:android   

二.匯入下載的高德sdk  和classes  jar檔案放在lib檔案下

      並點選右鍵新增依賴

三.編寫主函式

public class MainActivity extends UnityPlayerActivity

{
    //宣告mLocationClient物件
    public AMapLocationClient mLocationClient = null;
    public AMapLocationClientOption mLocationOption = null;
    private String LocationInfo;
    private String ErrorInfo="";

    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
    }
    //獲取定位資訊
    public String[] GetInfo()
    {
        String[] a=new String[2];
        a[0]=this.LocationInfo;
        a[1]=this.ErrorInfo;
        startLocation();

        return a;
    }

    protected void onStart()
    {
        super.onStart();
    }

    private void startLocation()
    {
        this.mLocationClient = new AMapLocationClient(getApplicationContext());
        //回撥監聽
        this.mLocationClient.setLocationListener(this.mLocationListener);
        //初始化定位引數
        this.mLocationOption = new AMapLocationClientOption();

        this.mLocationOption.setLocationMode(AMapLocationClientOption.AMapLocationMode.Hight_Accuracy);
        this.mLocationOption.setInterval(1000L);
        this.mLocationOption.setHttpTimeOut(10000l);
        this.mLocationOption.setNeedAddress(true);
        this.mLocationClient.setLocationOption(this.mLocationOption);
        this.mLocationClient.startLocation();
    }

    public AMapLocationListener mLocationListener = new AMapLocationListener() {
        @Override
        public void onLocationChanged(AMapLocation location) {

            if (location != null) {
                if (location.getErrorCode() == 0) {
                    StringBuffer sb = new StringBuffer(256);
                    SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
                    Date date = new Date(location.getTime());
                    String time=df.format(date);
                    sb.append("時間: " + time);
                    sb.append("\n緯度：" + location.getLatitude());
                    sb.append("\n經度：" + location.getLongitude());
                    sb.append("\n精度：" + location.getAccuracy());
                    sb.append("\n地址：" + location.getAddress());
                    sb.append("\n國家資訊：" + location.getCountry());
                    sb.append("\n省資訊：" + location.getProvince());
                    sb.append("\n城市資訊：" + location.getCity());
                    sb.append("\n城區資訊：" + location.getDistrict());
                    sb.append("\n街道資訊：" + location.getStreet());
                    sb.append("\n街道門牌號資訊：" + location.getStreetNum());
                    sb.append("\n城市編碼：" + location.getCityCode());
                    sb.append("\n地區編碼：" + location.getAdCode());
                    LocationInfo = sb.toString();
                }else {
                    StringBuffer errorinfo = new StringBuffer(256);
                    errorinfo.append("錯誤程式碼:"+location.getErrorCode());
                    errorinfo.append("\n"+location.getErrorInfo());
                    ErrorInfo=errorinfo.toString();
                }
            }
        }
    };
 

四.將模組打包成aar格式供unity互動

      修改 build.gradle檔案

  第一步:將apply plugin: 'com.android.appcation'修改為

apply plugin: 'com.android.library'

第二部:刪除  applicationId "com.test.sdk1"   

第三步:在AndroidMainfest檔案中修改

android:theme="@android:style/Theme.NoTitleBar">  新增

<meta-data android:name="unityplayer.UnityActivity"android
 
:value="true"/> 

第四步:在AndroidManifest.xml的application標籤中配置Key：

<meta-data android:name="com.amap.api.v2.apikey" android:value="您的Key"></meta-data>

             在application標籤中宣告service元件：

<service android:name="com.amap.api.location.APSService"></service>          

          在AndroidManifest.xml中配置許可權:
 

<!--用於進行網路定位-->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
<!--用於訪問GPS定位-->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
<!--獲取運營商資訊，用於支援提供運營商資訊相關的介面-->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
<!--用於訪問wifi網路資訊，wifi資訊會用於進行網路定位-->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
<!--這個許可權用於獲取wifi的獲取許可權，wifi資訊會用來進行網路定位-->
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
<!--用於訪問網路，網路定位需要上網-->
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<!--用於讀取手機當前的狀態-->
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
<!--寫入擴充套件儲存，向擴充套件卡寫入資料，用於寫入快取定位資料-->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
<!--用於申請呼叫A-GPS模組-->
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS"></uses-permission>
<!--用於申請獲取藍芽資訊進行室內定位-->
<uses-permission android:name="android.permission.BLUETOOTH"></uses-permission>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"></uses-permission>

五.unity中訪問android

  將打包出來的aar檔案和AndroidMainifest檔案放在Plugins/Android資料夾下

 此時就可以編寫c#程式碼了

public class Test : MonoBehaviour
{

    public Text content;
    public Button button;
    AndroidJavaClass jc;
    AndroidJavaObject jo;
    void Start()
    {
        content.text = "654321";
        OnStart();

    }
    public void GetLocation()
    {
        string[] a;
        OnStart();
        a = jo.Call<string[]>("GetInfo");
        content.text = a[0];
        if (a[1] != "")
        {
            content.text = a[1];
        }
    }
    void OnStart()
    {
        jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
    }

   unity呼叫android中的一些函式

這樣就簡單的實現高德的定位功能啦!
