Firebase Crashlytics 崩溃报告仅在应用程序在预发布测试中运行时出现

Question

I have followed and triple-verified all of the setup steps for adding firebase & crashlytics to my app here: https://firebase.google.com/docs/android/setup?hl=en and here: https://firebase.google.com/docs/crashlytics/get-started?authuser=0&platform=android , verified that the google-services.json is correct (actually re-downloaded it for comparison, and it works for Firebase messaging). Enabled Analytics sharing. Crashlytics enabled for my app on Firebase console. Some json reports do get logged as uploaded at runtime (not crashes) with a 204 result, but on startup, the app gets an error "E/FirebaseCrashlytics: Settings request failed. java.io.FileNotFoundException: https://firebase-settings.crashlytics.com/spi/v2/platforms/android/gmp/(snip)&build_version=99&display_version=2022.08.31.99 blah blah blah" and then when I click on my "TEST CRASH" button, I get another error " E/FirebaseCrashlytics: Cannot send reports. Timed out while fetching settings.".

The thing is, the crash reports DO appear for crashes that occur during the Google Play Pre-Release testing upon upload to Google Play (closed testing), including for the "CRASH TEST" button, and then I get crash-free users, logs, stack trace, the whole thing. Because this part is working, it would appear that my setup is correct.

I have Proton VPN installed on the device, but have disabled it during testing. It does not seem to matter.

NOTE: I cannot get the crash to upload whether the app was subsequently downloaded (beta) from Google Play or whether I compiled it, debug or release, in order to run it with Android Studio with USB debugging to the same device (but I have to uninstall one to install the other, and only the downloaded one has the option to "Report" the crash -- I don't know if the crash would ever be uploaded if I don't choose Report, but I have never seen a reported crash, in the Play Console, Firebase, or anywhere else.)

Does anyone know how I can get crashes to be reported to Crashlytics outside of Pre-release testing? Are there any prerequisites like "app has to have been uploaded with the same version" or "no VPN allowed" or "'Report' must be selected in popup dialog on device after the crash" or "display version string must not contain spaces" or anything else? (From some things I have read even on the docs, it appeared I should be able to be testing a local build and get crash reports.)

I am using the latest "Chipmunk" Studio. I just updated to the latest firebase BOM.

From my project-level build.gradle:

            // TODO remove in production

    private void addTestCrashButtonForCrashlytics() {
        Button crashButton = new Button(this);
        crashButton.setText("Test Crash");
        crashButton.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                throw new RuntimeException("Test Crash"); // Force a crash
            }
        });

My thanks in advance for anyone who can help me figure this out.

Answer 1

Son of a..., After DAYS on this problem, I just found the answer - the issue is, actually. that the display version had spaces in it, So, in the module level build.gradle: I had a descriptive versionName which explains in Google Play the latest summary of changes:

        versionName "2022.08.31.99 Blah, blah blah"

, which looked suspicious in the error "E/FirebaseCrashlytics: Settings request failed. java.io.FileNotFoundException: https://firebase-settings.crashlytics.com/spi/v2/platforms/android/gmp/(snip)&build_version=99&display_version=2022.08.31.99 blah blah blah", since URLs can't have spaces - so I tried changing it to just:

        versionName "2022.08.31.99"

I recompiled it and ran it over USB on the phone, tapped the test crash button and got a crash report almost immediately. Backed it out, the problem occurs, put it back, it's working! Hope this helps someone else!

By the way, this was working using a local debug build running over USB. Furthermore, it does not have to match an uploaded version in Google Play - I subsequently incremented it and it still reported a crash. It does seem to have an issue over VPN (it might be the particular server, or maybe just not allowed on VPN.) These were crashes that automatically uploaded to Crashlytics - I did not have to choose "Report" on a popup, and actually, could not because they were local builds, which as I mentioned earlier, don't give that option.
