向android studio導入多個unity3d項目？

Question

我能夠導出Unity3d的android項目，並在android studio中導入它，但我如何將多個unity3d項目導入到android studio？ 我試圖導入它作爲一個模塊，但沒有奏效。

每unity3d項目依賴於統一，classes.jar文件，所以當我導入多個項目，它拋出錯誤

Error:Execution failed for task :app:transformNative_libsWithMergeJniLibsForDebug'. com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK lib/armeabi-v7a/libmain.so

Answer 1

在這裏，我是如何解決這個。

首先，您必須將android和您的場景導出爲android並檢查Google開發。之後，你打開任何Android項目。

• 1.文件 - >新建 - >導入模塊...並選擇你的團結項目。

• 2.Open您的統一項目的gradle這個（ex.build.gradle（模塊：團結）），並刪除「應用插件：......」和的applicationID
  ，而是你加在上面「申請插件：「com.android.library」」

• 3.You去文件 - >項目結構和模塊，你的依賴性選擇app.Then，按下+ - >模塊依賴和
  您選擇你的團結工程。

• 4.在java UnityActivity中，將活動擴展爲Fragment，並添加此代碼。

  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); } 
      }

我得到了完全相同的問題，當我試圖導入兩項單位工程爲兩個庫到Android工作室。有兩種解決方法：

1. 在graddle.build你應用程式來添加：

   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' 
       } 
   
       ... 
   } 
   

2. 還是去項目窗口 - > Android的 - >在你的團結項目的一個定位文件夾jniLibs並刪除文件夾armeabi-v7和x86。
