title: Firebase App Distribution for Android from gradle with groups totalling more than 200 users
body: <p>I just migrated my Android app from <code>Fabric Beta</code> to <code>Firebase App Distribution</code>. My <code>Fabric</code> group <code>android</code> had <code>395</code> people in it, and <code>Firebase</code> only allows a maximum of <code>200</code> people in a group, so I split my <code>Firebase</code> groups into <code>android-1</code> and <code>android-2</code>.</p>
  
  <p>Here is my gradle definition:</p>
  
  <pre><code>firebaseAppDistribution {
    releaseNotes="Alpha"
    groups="android-1, android-2, qa"
  }
  </code></pre>
  
  <p>However, when I try to run my gradle task, I get the following error:</p>
  
  <pre><code>Execution failed for task ':app:appDistributionUploadRelease'.
  &gt; App Distribution halted because it had a problem adding testers/groups: [400] Request contains an invalid argument.
  </code></pre>
  
  <p>If I change <code>groups</code> to:</p>
  
  <pre><code>firebaseAppDistribution {
    releaseNotes="Alpha"
    groups="android-1, qa"
  }
  </code></pre>
  
  <p>or:</p>
  
  <pre><code>firebaseAppDistribution {
    releaseNotes="Alpha"
    groups="android-2, qa"
  }
  </code></pre>
  
  <p>everything works fine.</p>
  
  <p>I suspect that firebase just doesn't want to send more than <code>200</code> emails at a time when there's a new update.
  Does anyone have an idea how to work around this?</p>
  
  <p>Also, I'm trying to find the github project for this, so I can file an issue, but nothing is coming up.</p>
