Question

我能够导出Unity3d android项目并在android studio中导入它，但我如何将多个unity3d项目导入android studio？我尝试将其作为模块导入但不起作用。

每个unity3d项目都依赖于unity-classes.jar文件，因此当我导入多个项目时会抛出错误

错误：任务执行失败：app：transformNative_libsWithMergeJniLibsForDebug'。 com.android.build.api.transform.TransformException：com.android.builder.packaging.DuplicateFileException：在APK lib / armeabi-v7a / libmain.so
中复制的重复文件

我在这里解决了这个问题。

首先你必须将团结和你的场景导出为android并检查谷歌开发。之后，你打开任何android项目。

1.File - ＆gt; new-＆gt;导入模块......然后选择你的团结项目。
2.打开团结项目的gradle（ex.build.gradle（Module：unity））并删除“apply plugin：...”和applicationId
而你在顶部添加“apply plugin：'com.android.library'”
3.您可以转到文件 - >项目结构，在模块中选择您的应用程序。然后在依赖项中，按下+ - ＆gt;模块依赖和
你选择你的团结项目。

4.在java UnityActivity中，您将活动扩展为Fragment，然后添加此代码。

public class UnityActivity extends Fragment {
    protected UnityPlayer mUnityPlayer; // don't change the name of this variable; referenced from native code
     private static final String ARG_SECTION_NUMBER = "section_number";
 public static UnityActivity newInstance(int sectionNumber) {
     UnityActivity fragment = new UnityActivity();
     Bundle args = new Bundle();
     args.putInt(ARG_SECTION_NUMBER, sectionNumber);
     fragment.setArguments(args);
     return fragment;
 }
 public View onCreateView(LayoutInflater inflater, ViewGroup container,
                          Bundle savedInstanceState)
 {
     getActivity().getWindow().takeSurface(null);
     getActivity().setTheme(android.R.style.Theme_NoTitleBar_Fullscreen);
     getActivity().getWindow().setFormat(PixelFormat.RGB_565);
     mUnityPlayer = new UnityPlayer(getActivity());
     if (mUnityPlayer.getSettings ().getBoolean ("hide_status_bar", true)) {
         getActivity().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);
     mUnityPlayer.windowFocusChanged(true);
     mUnityPlayer.setX((float)-5);
     View playerView = mUnityPlayer.getView();
     return playerView;
 }
 // Quit Unity
 @Override public void onDestroy ()
 {
     mUnityPlayer.quit();
     super.onDestroy();
 }
 // Pause Unity
 @Override public void onPause()
 {
     super.onPause();
     mUnityPlayer.pause();
 }
 // Resume Unity
 @Override public void onResume()
 {
     super.onResume();
     mUnityPlayer.resume();
 }
 // This ensures the layout will be correct.
 @Override public void onConfigurationChanged(Configuration newConfig)
 {
     super.onConfigurationChanged(newConfig);
     mUnityPlayer.configurationChanged(newConfig);
 }
 // Notify Unity of the focus change.
 public void onWindowFocusChanged(boolean hasFocus)
 {
     super.getActivity().onWindowFocusChanged(hasFocus);
     mUnityPlayer.windowFocusChanged(hasFocus);
 }
 // For some reason the multiple keyevent type is not supported by the ndk.
 // Force event injection by overriding dispatchKeyEvent().
 public boolean dispatchKeyEvent(KeyEvent event)
 {
     if (event.getAction() == KeyEvent.ACTION_MULTIPLE)
         return mUnityPlayer.injectEvent(event);
     return super.getActivity().dispatchKeyEvent(event);
 }
 // Pass any events not handled by (unfocused) views straight to UnityPlayer
 public boolean onKeyUp(int keyCode, KeyEvent event)     { return mUnityPlayer.injectEvent(event); }
 public boolean onKeyDown(int keyCode, KeyEvent event)   { return mUnityPlayer.injectEvent(event); }
 public boolean onTouchEvent(MotionEvent event)          { return mUnityPlayer.injectEvent(event); }
 /*API12*/ public boolean onGenericMotionEvent(MotionEvent event)  { return mUnityPlayer.injectEvent(event); }
    }

当我尝试将两个Unity项目作为两个库导入Android Studio时，我遇到了完全相同的问题。你有两个解决方案：

在你的应用程序的graddle.build中添加：

android {
    ...

    packagingOptions {
        pickFirst 'lib/armeabi-v7a/libmain.so'
        pickFirst 'lib/armeabi-v7a/libmono.so'
        pickFirst 'lib/armeabi-v7a/libunity.so'
        pickFirst 'lib/x86/libmain.so'
        pickFirst 'lib/x86/libmain.so'
        pickFirst 'lib/x86/libmain.so'
    }

    ...
}

或者转到项目窗口 - ＆gt; Android - ＆gt;在您的一个Unity项目下找到文件夹 jniLibs 并删除文件夹 armeabi-v7 和 x86 。
