Splash Screen only shows for a fraction of a second (Android)

[Mison]

In one of my apps the Splash Screen shows for only part of a second (other app works fine).

- YouTube

Settings: should last for 3 seconds.

The splash screen works in your other apps but not this one? What is different about this one, are you using a different graphics API, android version or linear light?
Try turning the overlay opacity down.

Well, it works in my testing project which was derived from this one before (by deleting almost everything), so the settings are probably same. But the problem might be that I use some third party SDKs in this one, so the android manifest is probably different (I don’t know where I can find the merged one used in the build). One of them is Facebook, but I think the problematic one could be Crashlytics by Fabric.io as it wraps the activity by its own.

Mechanics of Unity Crash Handling
Crashlytics for Unity support is, effectively, a wrapper around the existing Android and iOS crash handlers. The plugin installs a C# exception handler, which forwards caught exceptions to logged exception methods in the native SDK via C#/Objective-C/Java interoperability.

For Android projects, the plugin modifies AndroidManifest.xml, replacing the existing launcher activity with its own. The launcher activity contains aFabric.with(context, new Crashlytics()) statement, which is necessary to instantiate Fabric. During the build process, a post-build script for Android will submit a build event to the backend.

oh that does sound like the culprit. We have tried to prevent the splash screen from jumping due to long loading but still not enough it seems. I suspect fabric is blocking Unity for a few seconds whilst it loads which is going to be difficult to fix. I’ll try and recreate the issue and see what I can do.
