Alternative fix for Unity 5.6 that does not require the setZOrderOnTop fix.

[nostek]

Creates a PopupWindow with 'layout' as child, instead of adding it to the activity.
This makes the Android version not require the setZOrderOnTop fix.

This is how Google Admob on Unity fixed it.

Tested on Android 6.0.1

Thank you very much. Unfortunately, the software keyboard seems not to be activated even if a text field is focused. Is it possible to solve this issue?

[nostek]

Ah, did not test for that.
I'll see if I can fix it when I'm back from holiday.

Apologies for not testing it thoroughly before making a pull request.

I just tested on the new Unity 2017 1.0 and the web view displays perfectly with the default unity android:name activity: com.unity3d.player.UnityPlayerActivity.

[KojiNakamaru]

@antoniohof Thanks for the information. Though I haven't tried yet, Unity 5.6.1p4 also seems to fix the issue (and thus it might be reflected in 2017 1.0):

(916119) - Android: Fixed a regression where Banner Ads are invisible, but still clickable.

I'll later add some note to README.md.

PopupWindow seems to not be working with keyboard input, so we can discard this.

I have a question, when I open a webView in game,then I touch "home" and return game back, will game be waked up with webview(if I leave android:name activity: com.unity3d.player.UnityPlayerActivity in unity 5.6.5)?

[KojiNakamaru]

The issue discussed here was only found in 5.6.0 and 5.6.1, so it should not affect 5.6.5. Therefore a web view should be shown up again when the game be waked up in the situation you describe.

I use Unity 2017.4.11f1 and build sample project to Android device with release build, but the webview is
total blank, and if build with development build, it will show content correctly.

Is this a Bug? Or I did something wrong? Thanks.

[KojiNakamaru]

I've confirmed the sample app built by Unity 2017.4.11f1 with release build works without any issue. You might install an incomplete apk as the first build for Android should have failed to adjust AndroidManifest.xml, as below:

[sky2005zx]

Thanks !! I Delete AndroidManifest and build again, and it work.

But there is another problem, my website has an autoplay html 5 video, it show in IOS, but in android, it is total black screen (But it show the play state and can heard the sound of video)

How to fix it ? Thx

(Sorry for my poor English)

[KojiNakamaru]

Hmm, did you rebuild the app, as designated in the screenshot above? For video display, https://github.com/gree/unity-webview/tree/4cc849f6920547dd1f7946cc81aa5143b89354eb#hardwareaccelerated is normally required.

[boboshu]

same when playing h5 video it is black screen on android . ios is ok.but when set hardwareaccelerated true. android is ok. I tested Uniwebview3 addons, when the hardwareaccelerated is false android, it is not black screen. my unity version is unity2017.4.17f
