Failed to fetch the following dependencies: com.google.android.gms:play-services-ads:19.0.0 - unity3d

I am using Unity 2019.3.6f1 and Google Mobile Ads Unity Plugin v5.0.1. I have imported the plugin to my Unity editor. When I try to resolve, error message appear and ask to look at console. Message at console "Failed to fetch the following dependencies: com.google.android.gms:play-services-ads:19.0.0". This is my third time making game using unity but first time happen to me. Hope anyone can give me idea what is happening and how to fix this.

"Can you confirm that you have the externs.cpp file in Assets/Plugins/Android (included in the Google Mobile Ads Unity package) and that it is checked for inclusion in Android builds, as per below?"
Answer taken from Issue in v5.0.1. See this.

I'm getting an error in the Unity Editor saying that I have multiple plugins. How can I fix this?

So, I have decided to use Agora for my multiplayer voice chat feature in my FPS Game. I have been getting this error recently in the Unity Editor saying that there are multiple plugins as seen in the screenshot provided. How can I get rid of this error?
The Error I'm Getting
Try removing it through the package manager, then reinstall agora through package manager.
It seems somehow the existing agora is not properly imported & the only way was to remove the other package from the package manager. That way the existing package remains untouched and unity will stop complaining about duplicate plugins.

How can I fix the WebGL build error in unity?

I made a game project in unity. And I want to build this to WebGL. But when it build, it shows error like
I searched the solution, and everyone say "delete using UnityEditor". So I did that, but it has error when I delete that in Photon script.
How can I my game build in Webgl with not delete using UnityEditor. Or How can I fix the error another solution ? Thank you for your anything helps.
I found the cause. I use Photon voice chat, but it doesn’t support WebGL. Remove that asset and project build work well.

Vuforia & Unity: Build UWP Successfully but No Live Camera Feed (Black Screen)

Unity Version: Unity 2019.3.9f1
Vuforia Version: 9.0.12
The app works fine in unity editor, it builds and runs successfully without error but no camera feed (black screen). Can't seem to find up to date solutions online.
Updated the Vuforia version to 9.2.7 does not seem to solve the problem.
I don't think to check the "Vuforia Augmented Reality Supported" under the "XR Settings" is an option, because it's able to deprecate. Also Checking the "Windows Mixed Reality" plug-in under XR Plug-in Management didn't solve the problem.
I already checked the "InternetClient" and "WebCam" in the publish setting for UWP.
Do I need to change anything in ARCamera's "Open Vuforia Engine configuration"? Some solutions mention disabling the Vuforia play mode will help, but I can't seem to find the option anywhere.
Anyone encountered the same issue and find a solution? Thanks.
I don't have a current solution, but would like to share my experience working with vuforia, UWP.
I found that there are varying breaking versions of unity and vuforia's SDK.
The latest version may not necessarily work I had to trial and error before I found a compatible version, so you might want to try that out. perhaps a older version of either unity/vuforia in reference with https://library.vuforia.com/platform-support/supported-versions.html
And yeah, definitely run your "hello world" tests on the sample projects first.
Best of luck, it's a great SDK ,once you get it to work.

Vuforia on Flutter says "engine init error"

Here iam working with Unity+Vuforia and Flutter
While i play and build the unity app in the unity with vuforia, it works fine
But after i export it to my flutter project using this method, when i press the button from my app to open the unity scene, it says : error screenshot
Any suggestions?
Regards, Slim
The package is corrupted, you can see the many problems in the issues section. Unity runs better on flutter using this package. You can see a full integration example we created in this repo.

Chartboost test scene not working in unity

I made an app for android with unity3d, and want to include chartboost into it. I imported the plugin for unity, and added an app as well as a campaign on chartboost. I also made sure that the signature and app name were put into the strings.xml file. When I tried running the demo scene, the buttons appeared, but when I tried to click them, nothing happens, not even a message in the console. What am I doing wrong?
Thanks for the help in advance!

As far as I know, chartboost does not work in the editor. You will need to build to a device and use logcat to see the log messages. However their unity plugin seems to be in need of some fixing- in the meantime, email them at support#chartboost.com and they should send you a workaround .jar file that will get the ads showing in the demo.
See my answer to This Question for details about why the ads aren't showing up using the newest Chartboost unity plugin.
I think their plugin is broken because my other apps DO show ads, and i did nothing different except using their latest plugin, which also for me does not work.
