Unity调用安卓

unity调android 本人目前发现android主activity必须继承UnityPlayerActivity，unity才能通过   

AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");

AndroidJavaObject   jo = jc.GetStatic<AndroidJavaObject>("currentActivity");  jo.call("函数名")

或者

AndroidJavaClass jc = new AndroidJavaClass("包名+.主Activity");

jc.CallStatic("函数名")；

unity调Android（一）中unity没法调用android 本文主要解决调用问题：

实现思路是通过activity切换调用的方式。受益于 雨凇momo教程 。让主activity继承UnityPlayerActivity，然后在主activity里通过 

Intent intent = new Intent(mContext,"子activity"+.class);
                    intent.putExtra("Activity", "Activity");
                    this.startActivity(intent);

以下主要实现代码：

public class SDKDemo extends UnityPlayerActivity{
    
    Context mContext=null;
    JoyActivity joyActivity;
    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);
        mContext=this;
        Intent intent = new Intent(mContext,JoyActivity.class);
        intent.putExtra("JoyActivity", "JoyActivity");        this.startActivity(intent); 
    }    
    public void nativeInit() {
        Log.e("nativeInit","nativeInit Enter");
        joyActivity=new JoyActivity();
        joyActivity.nativeInit();
        Log.e("nativeInit","nativeInit End");
    }public class JoyActivity extends Activity {

        UnityPlayer unityPlayer;    // UnityPlayer.init() should be called before attaching the view to a layout. 
    // UnityPlayer.quit() should be the last thing called; it will terminate the process and not return.
    protected void onCreate (Bundle savedInstanceState)
    {        super.onCreate(savedInstanceState);
        
    
        setTheme(android.R.style.Theme_NoTitleBar_Fullscreen);
        
        requestWindowFeature(Window.FEATURE_NO_TITLE);

        mUnityPlayer = new UnityPlayer(this);        if (mUnityPlayer.getSettings ().getBoolean ("hide_status_bar", true))
            getWindow ().setFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN,

                           WindowManager.LayoutParams.FLAG_FULLSCREEN);        int glesMode = mUnityPlayer.getSettings().getInt("gles_mode", 1);        boolean trueColor8888 = false;
        mUnityPlayer.init(glesMode, trueColor8888);
        View playerView = mUnityPlayer.getView();
        setContentView(playerView);
        playerView.requestFocus();    
    }

以上代码 也可以参考 unity调android(一)中的方式    public void nativeInit () {
        Log.e("nativeInit", "##########################");
    }

unity代码：void Start () 
    {
        jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
                jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
        jo.Call("nativeInit");
    }
