We strongly recommend that you perform a backup before importing UniWebView to your project. If you are using any version control systemopen in new window (like Git or SVN), it should be definitely safe to continue.

Unity Asset Store

If you purchased UniWebView from Unity Asset Storeopen in new window, open the Asset Store window from Window → Asset Store or Window → Package Manager. You could find UniWebView 5 there under My Assets, then click "Import".

UniWebView Store

Besides of Unity Asset Store, we also have our own storeopen in new window. After purchasing from our store, you could download the uniwebview_x_y_z.unitypackage (x_y_z in the file name indicates the package version). Open your project in which you want to use UniWebView, then double-click the downloaded file to import it.

Importing Package

Unity will prompt you with a window to confirm the importing files. Just click "Import" to add all files to your project.

The minimum deploy target of UniWebView is from iOS 9.0 and Android 5.0 (API Level 21). If you are still using an older deploy target for you Unity project, you may have some issues when exporting the project to the final product. Please make sure to update the Target minimum iOS Version and Minimum API Level in the player settings.

Restarting Unity

Restart the Unity app to give it a chance to load the UniWebView bundle for macOS Editor support. Remember to switch your build target in Player Setting to either iOS or Android, since UniWebView only works on these two platforms. Otherwise, UniWebView gives a warning, saying the platform is not supported yet.

Optional Steps

After importing UniWebView, you can open the Unity Preferences panel (Unity → Preferences) to configure some necessary permissions. In most cases, there is no need to adjust them and your project should build and run well. If your project can build without issues on both iOS and Android, you can skip these steps below and check the next chapter.

If you have any errors when building, you can use this panel to customize how UniWebView should adjust some behaviors or dependencies installation.

UniWebView uses a post-build script to modify the gradle project and "AndroidManifest.xml" file for the exported Android project.

Android Manifest

Settings in this section will be used to adjust the final AndroidManifest.xml file of the exported project.

Uses Cleartext Traffic

Set usesCleartextTraffic flag to true in the "AndroidManifest.xml". From Android 9.0, all plain HTTP traffic is forbidden by default.

If you need to display plain HTTP content in the web view, turn it on.

Write External Storage

Add WRITE_EXTERNAL_STORAGE permission to the "AndroidManifest.xml". It enables storing an image from the web page to the Download folder on the device.

If you need to download and save any files to disk, turn it on.

Access Fine Location

Add ACCESS_FINE_LOCATION permission to the "AndroidManifest.xml". It enables the web view to use the location information. To get the location actually, you also need to call LocationService.Startopen in new window before you open a web page.

If you need to use location APIs on the web, turn it on.

Gradle Build

You can use settings in this section to modify the build.gradle behavior when exporting the project. By default, UniWebView will add all dependencies it needs. However, if you are using another package manager or some embedded libraries, a duplication might happen when exporting to Android APK file. In this case, you can try to disable a certain option below to let UniWebView use the existing package instead.

Adds Kotlin

Whether Kotlin runtime should be added to the project. UniWebView for Android is written in Kotlin and you need the runtime in your project to run the code. It is on by default.

If any other packages of your project is already adding this, you can opt-out this option to skip adding Kotlin to the project.

Adds Android Browser

Whether the androidx.browser packageopen in new window should be added to the project. UniWebView uses some features in that package. It is on by default.

If any other packages of your project is already adding this, you can opt-out this option to skip adding the browser package to the project.

Enable Jetifier

Jetifieropen in new window migrates your support-library-dependent libraries to compatible with AndroidX. UniWebView requires androidx.browser package, which is only available as an AndroidX package. Making it on can allow to keep using AndroidX support libraries (if there are). It makes your project cleaner.

If you have to use a legacy support library and it cannot be migrated for some reason, disable this setting.

Auth Callbacks

This is set of OAuth 2.0 settings. You need to set the OAuth 2.0 callback URLs you want to support in this section. See the OAuth 2.0 guide for more information.
