Unity-Android的配置、集成、导出[Mac]

1.mac下安装配置Android SDK

[1]安装java jdk:http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
[2]sdk安装详见：http://www.cnblogs.com/yjmyzz/p/4219829.html
[3]安装android studio IDE

2.集成Android第三方sdk或使用原生功能并导出apk

[1]添加unity的class.jar文件，详见：http://www.narkii.com/club/thread-320335-1.html
[2]unity-classes Add To Library
[3]Android Studio 打Jar包见：http://blog.csdn.net/ta893115871/article/details/46955791/
[4]Jar包生成目录:

./mylibrary/build/intermediates/bundles/debug/classes.jar

[5]保存图片至android相册
java代码：

 // 保存照片至相册
    public static void savePng(final String fileName)
    {
        context = mainActivity.getApplicationContext();

        mainActivity.runOnUiThread(new Runnable() {
            public void run() {

                Bitmap bitmap = BitmapFactory.decodeFile(Environment
                        .getExternalStorageDirectory()
                        + "/Android/data/com.ztgame.snake/files/"
                        + fileName
                        + ".png");

                File file = new File(Environment.getExternalStorageDirectory()
                        + "/DCIM/Camera", fileName + ".jpg");

                FileOutputStream fos = null;
                try {
                    fos = new FileOutputStream(file);
                } catch (FileNotFoundException e) {
                    // TODO Auto-generated catch block
                    Log.w("cat", e.toString());
                }
                bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);

                try {
                    fos.flush();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    Log.w("cat", e.toString());
                }
                try {
                    fos.close();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    Log.w("cat", e.toString());
                }
                bitmap.recycle();//扫描保存的图片
                context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://" +Environment.getExternalStorageDirectory()
                        + "/DCIM/Camera/"+fileName + ".jpg")));

                Toast.makeText(context, "照片已保存到相册", Toast.LENGTH_SHORT).show();

            }
        });
    }

c#部分：

//先保存至本地目录
string name = "name";
string writePath = Application.persistentDataPath + "/" + name + ".png";
File.WriteAllBytes(writePath, b);
//调用原生代码复制到相册
AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
jo.CallStatic("savePng", name);

[6]将文本复制到剪贴板
java部分:

    // 向剪贴板中添加文本
    public static void copyTextToClipboard(final String str) throws Exception {
        context = mainActivity.getApplicationContext();
        if (Looper.myLooper() == null){
            Looper.prepare();
        }
        clipboard = (ClipboardManager) context.getSystemService(Activity.CLIPBOARD_SERVICE);

        ClipData textCd = ClipData.newPlainText("data", str);
        clipboard.setPrimaryClip(textCd);
        mainActivity.runOnUiThread(new Runnable() {
            public void run() {
                Toast.makeText(context, "链接已复制到剪贴板", Toast.LENGTH_SHORT).show();
            }
        });

    }

c#部分：

AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
jo.CallStatic("copyTextToClipboard", input);

[7]安装AndroidPlayer扩展即可导出

3.特别注意

[1]Android工程包名要和unity设置中保持一致
[2]如果横竖屏不能在unity设置中满足需求，可以在代码中强制调整
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
