While ParseLoginUI loading spinner is working activity is visible at background

Question

For my project, I am using ParseLoginUI with a dispatcher as shown here: https://github.com/ParsePlatform/ParseUI-Android/tree/master/ParseLoginSampleWithDispatchActivity

Answer 1

I found the solution. That dummy activity which starts unnecessarily is belong to Facebook. Which in our AndroidManifest.xml Facebook's LoginActivity looks like this:

<activity android:name="com.facebook.LoginActivity">

Add NoDisplay as Theme to it, so it doesn't show up on screen:

<activity android:name="com.facebook.LoginActivity"
          android:theme="@android:style/Theme.NoDisplay">

Answer 2

With update of new facebook sdk it is now works like this

<activity android:name="com.facebook.FacebookActivity"
        android:theme="@android:style/Theme.NoDisplay"
        tools:replace="android:theme"
        />
