内容介绍
# unity-webview unity-webview is a plugin for Unity 5 that overlays WebView components on Unity view. It works on Android, iOS, Unity Web Player, and Mac (Windows is not supported for now). unity-webview is derived from keijiro-san's https://github.com/keijiro/unity-webview-integration . ## Sample Project It is placed under `sample/`. You can open it and import the plugin as below: 1. Open `sample/Assets/Sample.unity`. 2. Open `dist/unity-webview.unitypackage` and import all files. It might be easier to extract `dist/unity-webview.zip` instead if you've imported unity-webview before. ## Common Notes ### UnityWebViewPostprocessBuild.cs `Assets/Plugins/Editor/UnityWebViewPostprocessBuild.cs` contains code for Android/iOS build, which may cause errors if you haven't installed components for these platforms. As discussed in https://github.com/gree/unity-webview/pull/397#issuecomment-464631894, I intentionally don't utilize `UNITY_IOS` and/or `UNITY_ANDROID`. If you haven't installed Android/iOS components, please comment out adequate parts in the script. ## Platform Specific Notes ### Mac (Editor) #### Auto Graphics API/Metal Editor Support The current implementation reiles on several OpenGL APIs so you need to disable "Auto graphics API" and specify OpenGLCore as below. ![auto-graphics-api-setting-for-mac.png](doc/img/auto-graphics-api-setting-for-mac.png) If you work only in (recent) Unity Editor, you may just disable "Metal Editor Support" (cf. https://github.com/gree/unity-webview/issues/383 ). ![metal-editor-support-setting-for-mac.png](doc/img/metal-editor-support-setting-for-mac.png) #### App Transport Security Since Unity 5.3.0, Unity.app is built with ATS (App Transport Security) enabled and non-secured connection (HTTP) is not permitted. If you want to open `http://foo/bar.html` with this plugin on Unity Mac Editor, you need to open `/Applications/Unity5.3.4p3/Unity.app/Contents/Info.plist` with a text editor and add the following, ```diff --- Info.plist~ 2016-04-11 18:29:25.000000000 +0900 +++ Info.plist 2016-04-15 16:17:28.000000000 +0900 @@ -57,5 +57,10 @@ <string>EditorApplicationPrincipalClass</string> <key>UnityBuildNumber</key> <string>b902ad490cea</string> + <key>NSAppTransportSecurity</key> + <dict> + <key>NSAllowsArbitraryLoads</key> + <true/> + </dict> </dict> </plist> ``` or invoke the following from your terminal, ```bash /usr/libexec/PlistBuddy -c "Add NSAppTransportSecurity:NSAllowsArbitraryLoads bool true" /Applications/Unity/Unity.app/Contents/Info.plist ``` ##### References * https://github.com/gree/unity-webview/issues/64 * https://onevcat.zendesk.com/hc/en-us/articles/215527307-I-cannot-open-the-web-page-in-Unity-Editor- #### WebViewSeparated.bundle WebViewSeparated.bundle is a variation of WebView.bundle. It is based on https://github.com/gree/unity-webview/pull/161 . As noted in the pull-request, it shows a separate window and allows a developer to utilize the Safari debugger. For enabling it, please define `WEBVIEW_SEPARATED`. ### iOS #### enableWKWebView The implementation now supports WKWebView but it is disabled by default. For enabling it, please set enableWKWebView as below: ```csharp webViewObject = (new GameObject("WebViewObject")).AddComponent<WebViewObject>(); webViewObject.Init( ... enableWKWebView: true); ``` (cf. https://github.com/gree/unity-webview/blob/de9a25c0ab0622b15c15ecbc0c7cd85858aa7745/sample/Assets/Scripts/SampleWebView.cs#L94) This flag have no effect on platforms without WKWebView (such as iOS7 and Android) and should always be set true for iOS9 or later (see the next section). #### WKWebView only implementation for iOS9 or later Apple recently sends the following warning for an app submission, > ITMS-90809: Deprecated API Usage - Apple will stop accepting submissions of apps that use > UIWebView APIs . See https://developer.apple.com/documentation/uikit/uiwebview for more > information. so the current implementation for iOS has two variations (Assets/Plugins/iOS/WebView.mm and Assets/Plugins/iOS/WebViewWithUIWebView.mm), in which new one (Assets/Plugins/iOS/WebView.mm) utilizes only WKWebView if iOS deployment target is iOS9 or later. Please modify `#if __IPHONE_OS_VERSION_MIN_REQUIRED < __IPHONE_9_0` in those files if you need to change this behavior. (Note: WKWebView is available since iOS8 but was largely changed in iOS9, so we use `___IPHONE_9_0` instead of `__IPHONE_8_0`) ### Android #### hardwareAccelerated The main activity should have `android:hardwareAccelerated="true"`, otherwise a webview won't run smoothly. Depending on unity versions, we need to set it as below (basically this will be done by post-process build scripts). ##### Unity 2018.1 or newer Based on the technique discussed in https://forum.unity.com/threads/android-hardwareaccelerated-is-forced-false-in-all-activities.532786/ and https://github.com/Over17/UnityAndroidManifestCallback, `Assets/Plugins/Editor/UnityWebViewPostprocessBuild.cs` edit the manifest to set `android:hardwareAccelerated="true"`. Please note this works with the `gradle` (not `internal`) build setting. ##### Unity 2017.x - 2018.0 Unity forcibly set `android:hardwareAccelerated="false"` regardless of its setting in `Plugins/Android/AndroidManifest.xml`, as discussed in https://github.com/gree/unity-webview/issues/382 (see also https://github.com/gree/unity-webview/issues/342 and https://forum.unity.com/threads/android-hardwareaccelerated-is-forced-false-in-all-activities.532786/ ), and there is no solution for automatically correcting this setting. Please export the project and manually correct `AndroidManifest.xml`. ##### Unity 5.x or older After the initial build, `Assets/Plugins/Editor/UnityWebViewPostprocessBuild.cs` will copy `Temp/StatingArea/AndroidManifest-main.xml` to `Assets/Plugins/Android/AndroidManifest.xml`, edit the latter to add `android:hardwareAccelerated="true"` to `<activity android:name="com.unity3d.player.UnityPlayerActivity" ...`. Then you need to build the app again to reflect this change. *NOTE: Unity 5.6.1p4 or newer (including 2017 1.0) seems to fix the following issue (cf. https://github.com/gree/unity-webview/pull/212#issuecomment-314952793)* For Unity 5.6.0 and 5.6.1 (except 5.6.1p4), you also need to modify `android:name` from `com.unity3d.player.UnityPlayerActivity` to `net.gree.unitywebview.CUnityPlayerActivity`. This custom activity implementation will adjust Unity's SurfaceView z order. Please refer `plugins/Android/src/net/gree/unitywebview/CUnityPlayerActivity.java` and `plugins/Android/src/net/gree/unitywebview/CUnityPlayer.java` if you already have your own activity implementation. #### Camera/Audio Permission/Feature For allowing camera access (`navigator.mediaDevices.getUserMedia({ video:true })`), please define `UNITYWEBVIEW_ANDROID_ENABLE_CAMERA` so that `Assets/Plugins/Editor/UnityWebViewPostprocessBuild.cs` adds the followings to `AndroidManifest.xml`. ```xml <uses-permission android:name="android.permission.CAMERA" / rel='nofollow' onclick='return false;'> <uses-feature android:name="android.hardware.camera" /> ``` For allowing microphone access (`navigator.mediaDevices.getUserMedia({ audio:true })`), please define `UNITYWEBVIEW_ANDROID_ENABLE_MICROPHONE` so that `Assets/Plugins/Editor/UnityWebViewPostprocessBuild.cs` adds the followings to `AndroidManifest.xml`. ```xml <uses-permission android:name="android.permission.MICROPHONE" /> <uses-feature android:name="android.hardware.microphone" /> ``` Details for each Unity version are the same as for hardwareAccelerated. Please also note that it is necessary to request permissions at runtime for Android API 23 or later as below: ```diff diff --git a/sample/Assets/Scripts/SampleWebView.cs b/sample/Assets/Scripts/SampleWebView.cs index a62c1ca..a5efe9f 100644 --- a/sample/Assets/Scripts/SampleWebView.cs +++ b/sample/Assets/Scripts/SampleWebView.cs @@ -24,6 +24,9 @@ using UnityEngine; using
