Unity高德LBS

1、準備

高德開發者頁面註冊產品 

1.1 http://www.cnblogs.com/U-tansuo/archive/2013/04/25/unity3d_android_sign.html

 

1.2填寫應用應用信息

 

 

1.3下載Android 定位SDK 

http://lbs.amap.com/api/android-location-sdk/locationsummary

解壓獲得 AMap_Location_V3.6.1_20171012.jar

 

二．新建Eclipse項目

2.1首先新建一個Android工程，在最小SDK版本里選4.0以上，否則在Unity打包的時候會報錯。

 

2.2導入AMap_Location_V3.6.1_20171012.jar和Unity提供的JAR庫classes.jar

位置：

D:\Program Files\Unity17103\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\il2cpp\Development\Classes

2.5Eclipse選中咱們的工程文件夾，能夠先點擊工具欄的Project->clean，再Project->Build Project。而後右鍵Export，選導出爲JAR文件導出jar包

 

2.6Unity部分

將安卓工程的文件拷貝到Unity工程的Plugins->Android文件夾裏。沒有這個目錄的話須要本身建立一個。文件夾目錄以下，把咱們剛剛導出的JAR文件放在的bin文件夾中，另外還須要把咱們的安卓工程目錄裏把libs文件夾和res文件夾以及AndroidManifest文件拷貝進去，注意拷貝完要把libs文件夾裏面的classes.jar文件刪掉，否則文件會衝突

   

 

 

2.7代碼GetLocationInfo.CS

 

using UnityEngine;
using UnityEngine.UI;

public class GetLocationInfo : MonoBehaviour {
    public Text text;
    // Use this for initialization
    void Start()
    {
        InvokeRepeating("StartLocation", 1, 5);
    }

    public void StartLocation()
    {
        AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
        text.text = jo.Call<string>("GetInfo");
    }
}

2.9Unity打包配置

 

 

三根據返回錯誤代碼判斷錯誤
