title: ActivityNotFoundException: No Activity found to handle Intent sospicious behaviour
body: <p>I have an app in production and in the last 24 hrs I received something like 50 crashes from a single user (3-4 per hour).</p>
  
  <p>Fabric marks the device type as "sdk" and the OS version is always 4.1.1.</p>
  
  <p>This is the stacktrace:</p>
  
  <pre><code>Fatal Exception: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=market://details?id=com.google.android.gms&amp;pcampaignid=gcore_8487000--- flg=0x80000 pkg=com.android.vending }

  <p>There is no sign of my package name, looks like the app is trying to open an internal intent of which I have no control over.</p>
  
  <p>Could that be an user/bot without Google Play Store? </p>
