1.隐藏虚拟键盘,即Navigation/System Bar.

原文:Hiding the navigation/system bar in Android

protected void onCreate(Bundle paramBundle){    requestWindowFeature(1);    super.onCreate(paramBundle);    getWindow().takeSurface(null);    setTheme(16973831);    getWindow().setFormat(4);    this.mUnityPlayer = new UnityPlayer(this);    if (this.mUnityPlayer.getSettings().getBoolean("hide_status_bar", true))    {        getWindow().setFlags(1024, 1024);    }    setContentView(this.mUnityPlayer);    this.mUnityPlayer.requestFocus();}

另外一种解决方案(之前使用的这种)

private int currentApiVersion;// 丢入OnCreate中用来隐藏虚拟按键private void HideNavigationBar(){    // This work only for android 4.4+    if (currentApiVersion >= Build.VERSION_CODES.KITKAT)    {        currentApiVersion = android.os.Build.VERSION.SDK_INT;        final int flags = View.SYSTEM_UI_FLAG_LAYOUT_STABLE |                           View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION |                           View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN |                           View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |                           View.SYSTEM_UI_FLAG_FULLSCREEN |                           View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;        getWindow().getDecorView().setSystemUiVisibility(flags);        // Code below is to handle presses of Volume up or Volume down.        // Without this, after pressing volume buttons, the navigation bar        // will        // show up and won't hide        final View decorView = getWindow().getDecorView();        decorView.setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener()        {            @Override            public void onSystemUiVisibilityChange(int visibility)            {                if ((visibility & View.SYSTEM_UI_FLAG_FULLSCREEN) == 0)                {                    decorView.setSystemUiVisibility(flags);                }            }        });    }}// @SuppressLint("NewApi")// @Overridepublic void onWindowFocusChanged(boolean hasFocus){    super.onWindowFocusChanged(hasFocus);    if(currentApiVersion >= Build.VERSION_CODES.KITKAT && hasFocus)    {        getWindow().getDecorView().setSystemUiVisibility(        View.SYSTEM_UI_FLAG_LAYOUT_STABLE       |        View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION  |        View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN   |        View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |         View.SYSTEM_UI_FLAG_FULLSCREEN  |         View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);    }}

2. Unsupported major.minor version 52.0.

出现这个问题的原因貌似是因为我更新了一下AndroidStudio….然后jdk出现了错误.
根据Google以及百度的答案是因为Jdk不匹配,所以解决方案是更新Jdk.

3.Unity用dll加载慢.

在dll的属性中加上
[assembly: UnityEngine.UnityAPICompatibilityVersion(“5.4.0f3”)]

4.获取某个方法执行时间.

using UnityEngine;using System.Collections;using System.Diagnostics;public class NewBehaviourScript : MonoBehaviour {    void Start ()     {        float t = Time.time;        TestMethod();        UnityEngine.Debug.Log(string.Format("total: {0} ms",Time.time - t));        Stopwatch sw = new Stopwatch();        sw.Start();        TestMethod();        sw.Stop();        UnityEngine.Debug.Log(string.Format("total: {0} ms",sw.ElapsedMilliseconds));        Profiler.BeginSample("TestMethod");        TestMethod();        Profiler.EndSample();    }    void TestMethod()    {        for(int i =0; i < 10000000; i++)        {        }    }}
