title: Branch.io links do not work on open alpha release
body: <p>I set up some deep linking to my android application mostly following <a href="https://github.com/BranchMetrics/android-branch-deep-linking" rel="nofollow noreferrer" title="Branch.io github doccumentation">Branch.io's github documentation</a> and the links work fine during development, however they do not work with the open alpha version of the app downloaded from google play. Clicking on a link will still open the desired activity within the app, however it seems like the metadata from Branch is being lost so I cannot populate the activity with the data from the link.</p>
  
  <p>I retrieve the link in the activity with code like this</p>
  
  <pre><code>Branch branch = Branch.getInstance(getApplicationContext());
  branch.initSession((referringParams, error) -&gt; {
          if (error == null) {
              //disect the params and populate the activity
          }
          else {
              Timber.e("Branch errored with " + error.getMessage());
          }
      }, intent.getData(), this);
  </code></pre>
  
  <p>And the android manifest has branch set up like this (with the correct keys)</p>
  
  <pre><code>&lt;meta-data
          android:name="io.branch.sdk.TestMode"
          android:value="false"/&gt;
  
   &lt;meta-data
          android:name="io.branch.sdk.BranchKey"
          android:value="key_live_XXXX"/&gt;
  
   &lt;meta-data
          android:name="io.branch.sdk.BranchKey.test"
          android:value="key_test_XXXX"/&gt;
  </code></pre>
  
  <p>Has anyone else dealt with a problem like this with the link metadata not working on a release build but works on other builds? </p>
  
  <p>Additionally there is also an iOS version of the app that shares a Branch account and has the same problem so I'm assuming it's a configuration problem with Branch</p>
