Hessenschau-App is crashing with latest release

after upgrading vi F-Droid to latest release the Hessenschau App crashes instantly. Verified on two devices. microG selfcheck is ok. logcat.txt

@mar-v-in I really like MicroG and want to give something "back" and therefore try to help with fixing those bugs… I installed emulator (from https://github.com/microg/android_packages_apps_GmsCore/wiki/Development-Tools) and built master of play-services-core. Now I can reproduce the Hessenschau-app crash.

As always, starting with helping in an unkown project is the hardest… Can you give me some rough hints, what I can do? After I have some experience, I can also put those info in the wiki.

According to logcat there are two crashes:

2020-10-25 11:36:47.516 4941-4941/de.hr.hessenschau E/FirebaseInstanceId: Failed to start service while in background: java.lang.IllegalStateException: Not allowed to start service Intent { act=com.google.firebase.INSTANCE_ID_EVENT pkg=de.hr.hessenschau cmp=de.hr.hessenschau/com.google.firebase.iid.FirebaseInstanceIdService (has extras) }: app is in background uid UidRecord{291254a u0a113 SVC  idle change:idle|uncached procs:1 seq(0,0,0)}

This seems to be the first/real crash: It cannot start the intent correctly. FirebaseInstanceId seems to be within in com.google.firebase.firebase-iid, but I cannot find any reference within microG for this?

After enabling SafetyNet, device regiseration, cloud messaging, I reinstalled Hessenschau and now get:

I find com.google.android.gms.common.internal in play-services-basement, but as the above stacktrace is obfuscated, I do not know where/if I can add a breakpoint to those classes.

Do you have an hint for this?

This is then the following up crash, which shows that the crash api is not implemented/working. Having a microG module for logging might help for easier debugging…?

more verbose logcat gives me above error.

Returning 1 in this case, leads me to:

I added some debug output:

com.google.android.gms D/RegisterRequest: Key: gmp_app_id with valued 1:878511340774:android:127798a550a15c81

        at android.os.BaseBundle.getString(BaseBundle.java:1163)

So it seems that indeed the value is 6 (integer), which leads to this crash.

When I add a cast in RegisterRequest.java: extraParams (L:124):

Object object = extraBundle.get(key);

                if (object instanceof String) {
                    extraParam(key, extraBundle.getString(key));
                } 
                if (object instanceof Integer) {
                    extraParam(key, String.valueOf(extraBundle.getInt(key)));
                }

I do not see any crash, I can hunt down, but only:

@tobiasKaminsky

Not every exception logged actually leads to a crash. For example, you can freely ignore all those Bundle: Attempt to cast generated internal exception. The exception that leads to the crash is always marked as FATAL EXCEPTION.
Returning any version > 0 in dynamite loader can cause apps to try loading code from microG package and if the corresponding code is not there, they're more likely to crash then if the version was set to 0. Thus changing the version alone most likely won't improve anything.

To solve this issue, one has to find out what is the reason for GoogleApiHandler to throw this IllegalStateException: A fatal developer error has occurred. Check the logs for further information.. The error message itself is not helpful at all in debugging, but there probably is a good reason for it to be thrown.

@mar-v-in thank you for your valuable feedback to understand the internal handling of microG!

Do you have an idea how to debug this? As far as I can see GoogleApiHandler is related to Firebase, but not directly debugable… E.g. I cannot set a breakpoint in Android Studio, nor I can add debug code to calling apk, as it is closed source…

Interesting, when I add a breakpoint to BaseService.java:47 and just keep debugger breaking at this point, I can use the app without problems.

E.g. I cannot set a breakpoint in Android Studio, nor I can add debug code to calling apk, as it is closed source…

I searched a lot on the internet to find out how I can try to debug this…but I still have no clue. If you have any tip, this would be awesome!

there is a new version of the Hessenschau app (1.9.1). Now the app is still crashing, but when you restart two or three times it is running without problems - until the next complete restart. Other apps of the same developer (Radio Station) are working without problems. Not shure if this is really a microG or more an application bug...

tested on two devices, seems this bug is fixed with the latest release v0.2.15.204713.

Thanks for the great work!

microg / GmsCore

Hessenschau-App is crashing with latest release #1244
