Black Screen after obfuscating with proguard

Hi,
In my debug version Unity Ads works without problems. Also in my release version with proguard deactivated. But when I use proguard to obfuscate the code the screen turns black after call show().

I copied all proguard settings to the end of my proguard-settings.txt. (see attachment)
No error is thrown. Debug output looks normal. In the attachment you can find the debug ouput from unityAds.

Do you have any clue what I can change?

Best Regards
Wolfgang

 

With black screen I mean the black gradient, which shows up before the "buffer video" - message appears.

 

I seem to be experiencing a similar problem, I do have some debug output though.

I'm using signed apks exported from Eclipse. Our app is mainly native code, with Java code for interfaces to cloud save, advertising SDKs etc. With proguard disabled, I see an ad and all seems fine.
However, with proguard enabled - and all the entries from unity-ads/proguard-project.txt copied into my proguard-project.txt - when I try to display an interstitial, I see a black screen.

At the black screen; the back key does not back out of it. The home key takes us home, but switching back to our app takes us back to the black screen.

Here's the relevant parts of the adb tty:

[first there's some tty from our native code handling APP_CMD_PAUSE, APP_CMD_LOST_FOCUS, APP_CMD_TERM_WINDOW]

I/ActivityManager( 552): Displayed com.<redacted>/com.unity3d.ads.android.view.UnityAdsFullscreenActivity: +554ms
I/WindowManager( 552): Screen frozen for +555ms due to Window{ded877 u0 com.<redacted>/com.unity3d.ads.android.view.UnityAdsFullscreenActivity}

[here there's some tty from our native code handling APP_CMD_SAVE_STATE, APP_CMD_STOP
and FlurryAgent reporting end of our session]

At this point, we're at the black screen.

 

Actually, the screen is not totally black, its graduated from black at one end to grey at the other.

The above tty was from Nexus 4 running Android 5.0.1
On A Samsung S3 running Android 4.3, relevant tty is rather different. Extracted from the Sammy's spammy tty:

[just prior to tty from our native code handling APP_CMD_LOST_FOCUS]

V/webkit (15195): BrowserFrame constructor: this=Handler (android.webkit.BrowserFrame) {42654bd0}

D/webcore (15195): CORE loadUrl: called
D/webkit (15195): Firewall not null
D/webkit (15195): euler: isUrlBlocked = false

[then, a little after tty from our native code handling APP_CMD_SAVE_STATE, APP_CMD_STOP
and FlurryAgent reporting end of our session]

D/WebView (15195): loadUrlImpl: called

Epilogue - thanks, but as we can't release un-obfuscated code, we did not implement Unity Ads for this reason.

 

Hi! Something similar is happening to me when I try to implement UnityAds in an Android Game (OpenGL, MOAI Framework): when I try to show the video, the screen turns black and I can't go back.

This is de debug output at the start of the app:

And the output when I show the VideoAd:

I added all the "proguard-project.txt" to my proguard file, but it doesn't seem to work...

Thank you!
