Intermittent Android SDK crashing when Intercom is experiencing downtime.

Question

The Intercom servers went down on June 6 causing multiple crashes of our app. The advice from Intercom at the time was to upgrade to 12.4.1, which we did and this solved the issue until today, when the server went down again (as per intercomstatus.com) and our app had multiple crashes.  The crashes being caused when the intercom log event is triggered in our app. Intercom.client().logEventPlease advise on the solution.  Our crashlytics shows the following crash data :ErrorStringExtractor.kt line 8io.intercom.android.sdk.api.ErrorStringExtractorKt.extractErrorString Fatal Exception: com.google.gson.JsonSyntaxException: Expected a com.google.gson.JsonObject but was com.google.gson.JsonPrimitive       at com.google.gson.internal.bind.TypeAdapters$33$1.read(TypeAdapters.java:869)       at com.google.gson.Gson.fromJson(Gson.java:963)       at com.google.gson.Gson.fromJson(Gson.java:928)       at com.google.gson.Gson.fromJson(Gson.java:877)       at com.google.gson.Gson.fromJson(Gson.java:848)       at io.intercom.android.sdk.api.ErrorStringExtractorKt.extractErrorString(ErrorStringExtractor.kt:8)       at io.intercom.android.sdk.api.Api$1.onError(Api.java:225)       at io.intercom.android.sdk.api.BaseCallback.handleError(BaseCallback.java:43)       at io.intercom.android.sdk.api.BaseCallback.onResponse(BaseCallback.java:28)       at retrofit2.DefaultCallAdapterFactory$ExecutorCallbackCall$1.lambda$onResponse$0(DefaultCallAdapterFactory.java:89)       at retrofit2.DefaultCallAdapterFactory$ExecutorCallbackCall$1.$r8$lambda$hVGjmafRi6VitDIrPNdoFizVAdk(DefaultCallAdapterFactory.java)       at retrofit2.DefaultCallAdapterFactory$ExecutorCallbackCall$1$$InternalSyntheticLambda$0$daf5173ad73a9dc0e8131143f299c222e2ca4cddd7cb10b2d0a6e331a0602ae1$0.run(DefaultCallAdapterFactory.java:6)       at android.os.Handler.handleCallback(Handler.java:938)       at android.os.Handler.dispatchMessage(Handler.java:99)       at android.os.Looper.loop(Looper.java:264)       at android.app.ActivityThread.main(ActivityThread.java:8312)       at java.lang.reflect.Method.invoke(Method.java)       at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:632)       at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1049)

Hey @mike c​, &#128075; thanks for reaching out! I'm one of the Support Engineers here @ Intercom! &#128077;Thanks for sharing these details, it is really helpful. The root cause here was our Android SDK not gracefully handling a specific kind of failure for an Intercom API call, resulting in a crash.While you were encouraged to upgrade to version "12.4.1", I will ask if it's possible for you to upgrade to the latest version "12.4.2". I can confirm the latest version of the Android SDK (12.4.2) has been made robust against these failures. I hope this clarifies, please let me know if you have any questions.
