Deprecate InstallReferrerReceiver in favor of Google Play install referrer

New features

• Referrer details are now fetched from Google Play since INSTALL_REFERRER message is no longer supported by Google. If you have the following lines, please remove them from your AndroidManifest.xml:

Remove:

<receiver
  android:name="com.mixpanel.android.mpmetrics.InstallReferrerReceiver"
  android:exported="true">
  <intent-filter>
    <action android:name="com.android.vending.INSTALL_REFERRER" />
  </intent-filter>
</receiver>

You now need to use a new Google dependency to be able to track your referrer details. Update your build.gradle file and add the following dependency:

Add:

dependencies {
        implementation 'com.android.installreferrer:installreferrer:1.1'
        ...
}

As before, Mixpanel referrer track will inspect the referrer and not only set a new property referrer but will also look for the following keys and set them as event properties separately (if available): utm_source, utm_medium, utm_term, utm_content and utm_campaign.

Fixes

• ConcurrentModificationException using super properties (#658)
• Track session lengths as a numbers and not strings.
• In-app notification NullPointerException.
• Capture exception when writing on SQLite and restore state.
• Do not allow null values as distinct_id.
