unity3d调用安卓java

一、unity3d调用java

unity里面想要获取安卓设备的唯一ID，必须通过原生的java接口来获取。

首先创建一个安卓库文件工程，里面新建一个java类，并从UnityPlayerMainActivity类派生，如下代码所示：

public class AndroidPlugin extends UnityPlayerMainActivity
    {
        private   static String unitygameobjectName = "_main"; //Unity 中对应挂脚本对象的名称
        private static AndroidPlugin thisActivity=null;
        public final static int FILECHOOSER_RESULTCODE = 19238467;     
        protected static ValueCallback<Uri> _uploadMessages;
        protected static ValueCallback<Uri[]> _uploadCallback;
        protected static String _cameraPhotoPath;
        protected static final String LOG_TAG = "AndroidPlugin";
        private static final String TAG = "AndroidPlugin";
        private int _textureId = 0;
        private SurfaceTexture _surfaceTexture;
        private IjkMediaPlayer player = null;
        private Texture2DExt mTexture2DExt;
        private Texture2D mUnityTexture;
        private FBO mFBO;
        private float[] mMVPMatrix = new float[16];
    
        private MyPluginCallbackListener _listener;
    
        public static Activity getUnityActivity_()
        {
            return thisActivity;//UnityPlayer.currentActivity;
        }
    
        @Override
        public void onCreate(Bundle savedInstanceState)
        {
            thisActivity = this;
            super.onCreate(savedInstanceState);  
        }
    
     public static String getAndroidUUID()
        {
            String deviceID = "androiduuid";
            if (ContextCompat.checkSelfPermission(thisActivity, android.Manifest.permission.READ_PHONE_STATE) != 0)
            {
                ActivityCompat.requestPermissions(thisActivity, new String[] {Manifest.permission.READ_PHONE_STATE}, 9999);
            }
            else
            {
                TelephonyManager tm = (TelephonyManager)getUnityActivity_().getSystemService(Context.TELEPHONY_SERVICE);
                deviceID = tm.getDeviceId();
            }
    
            Log.d("androiduuid", "androiduuid is:" + deviceID);
            return deviceID;
        }
    ｝

AndroidPlugin类里面添加需要调用的接口，比如：getAndroidUUID，将此类编译成一个jar库文件，复制到Plugins\\Android\\libs目录下。

c\#需要添加以下相关的代码：

void Awake()
        {
    #if UNITY_STANDALONE_WIN || UNITY_EDITOR
    
    #elif UNITY_ANDROID
            //   unityClassObj = new AndroidJavaClass(UNTIFY_CLASS);
            AndroidJavaClassObj = new AndroidJavaClass(JAVA_CLASS);
            AndroidJavaObj = AndroidJavaClassObj.CallStatic<AndroidJavaObject>("getUnityActivity_");
    #endif
         }
    
     public string GetDeviceID()
        {
            if (Application.platform != RuntimePlatform.OSXEditor && Application.platform != RuntimePlatform.WindowsEditor)
            {
                try
                {
    #if UNITY_ANDROID
                    //AndroidJavaObject curA = unityClassObj.GetStatic<AndroidJavaObject>("currentActivity");    
                    string aID = SystemInfo.deviceUniqueIdentifier;
                    if (AndroidJavaObj != null)
                        aID = AndroidJavaObj.CallStatic<string>("getAndroidUUID");
                    return "ANDROID-" + aID;
    #elif UNITY_IPHONE
            string iID = GetIphoneADID();
            return "IOS-"+iID;
    #endif
                }
                catch (System.Exception e)
                {
                    Debug.Log(e);
                }
                return SystemInfo.deviceUniqueIdentifier;
            }
            return SystemInfo.deviceUniqueIdentifier;
        }
