Pass Breadcrumbs Between Unity and Android - UnityAsALibrary

[thinkocapo]

What problem could Sentry solve that it doesn't?

Customer uses Unity As A Library. We think 'scope observer' is not getting set.

'Scene' logs are shown but not the unity logger Unity=> logs from the unity layer.

There are logs captured by the UnitySDK and say unity.logger Unity=> and user says these are the logs he wants captured on the sentry.android.native SDK event.

UNITY-159 Pass Breadcrumbs Between Unity and Android

[bitsandfoxes]

During Init, when running on Android and with native-support enabled we configure the Android SDK at runtime

sentry-unity/src/Sentry.Unity.Android/SentryNativeAndroid.cs

Line 72 in 0130165

options.ScopeObserver = new AndroidJavaScopeObserver(options, SentryJava);

and add the Android ScopeObserver

sentry-unity/src/Sentry.Unity.Android/AndroidJavaScopeObserver.cs

Lines 19 to 20 in 0130165

	public override void AddBreadcrumbImpl(Breadcrumb breadcrumb) =>
	_sentryJava.AddBreadcrumb(breadcrumb);

that need to pass the breadcrumbs from the C# layer to native.

The current recommendation is to disable native support in UaaL scenarios which effectively prevents this.
We need to look into keeping native support enabled and let the Unity SDK "discover" if there is an instance of the Android SDK available in the surrounding app.
