I am trying to implement google-admob mediation and currently working on Integrating InMobi ads. I followed all the steps as per https://developers.google.com/admob/unity/mediation/inmobi .I was able to create the Account ID and Placement ID in the inMobi website . I successfully was able to configure AdMob ad unit in my admob account.
The problem is in the 3rd step of the process which is "Import the InMobi SDK and adapter". I extracted the latest version of Google Mobile Ads mediation plugin for InMobi from this link https://developers.google.com/admob/unity/mediation/inmobi#inmobi-unity-mediation-plugin-changelog .
But while performing this step Assets > Play Services Resolver > Android Resolver > Force Resolve , I am getting the following "Android Dependencies , Resolution failed" error. I am attaching the screen shot and the log file below. I tried to change the version of the InMobi Unity Mediation Plugin some 5 times,but all the time it keeps failing. I changed to stack trace to full and understand but still can't really figure out what to do.
For inMobi ad mediation for unity there is no video on youtube also. Please help me to figure out the solution for this problem.
