Facebook-sdk-for-unity: AppCompat library increases dex count significantly

Created on 27 Nov 2016 · 12Comments · Source: facebook/facebook-sdk-for-unity

From my last calculations it increases it by about 12k, which is pretty bad. Is there a way to only ship this with the required styles. These are the required styles:

 <style name="com_facebook_activity_theme" parent="@style/Theme.AppCompat.NoActionBar">
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowNoTitle">true</item>
    </style>
    <style name="com_facebook_auth_dialog" parent="@style/Theme.AppCompat.Dialog">
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsFloating">true</item>
    </style>

I am having the same issue, I downgrade to 7.8 until I find a solution for this issue

Multi-Dex is not a good option according to Unity Official

From what i've seen, it's the Android support library that adds a lot to the method count.
Is there any option to analyze the APIs that are needed by the FB SDK and create a process that will generate a "stripped down" version of those libraries ?

The core FB android SDK requires these libraries. On normal Android Apps this is not an issue due to the support for multi dex and proguard.

Well, there is a huge amount of Unity games using the Facebook SDK, and Unity is not a "normal Android App".
Please fix this issue!

I also had a problem with 7.9.4, in my case it increased ref count from 46k to 86k, which is really strange, then I tried 7.8.0, and ref count only increased from 46k to 52k.

Change @style/Theme.AppCompat.NoActionBar into @style/Theme.Light.ActionBar
and @style/Theme. AppCompat.Dialog into @style/Theme.Dialog

Why was this closed? It's still an issue.

Still an issue. I'm trying desperately to minimize the ref count, but this library is simply too big...

@swiese Unity does not support multidex (without some rather extravagant workarounds). I may be mistaken, but isn't the entire purpose of a dedicated Unity SDK because it is different?

For anyone else that stumbles across this issue and needs a solution:

It's unfortunate that we are trapped between two dev teams that are both unwilling to help users.
