B4i Library Firebase Crashlytics

Biswajit · May 11, 2020

This is a wrapper of Firebase Crashlytics library for B4i. I made this for @Jack Cole and he gave me permission to post this in forum to help other users.

iFirebaseCrashlytics

Author: @Biswajit
Version: 2

Crashlytics
- Events:
  - HasUnsentReports
- Functions:
  - checkForUnsentReports
    Check for unsent reports
    You must set setCrashlyticsCollectionEnabled to false in order to use hasUnsentReports
    If there is any unsent report the EventName_HasUnsentReports event will be raised
  - deleteUnsentReports
    Delete unsent reports
  - didCrashDuringPreviousExecution As Boolean
    Detect when a crash happens during your app's last run.
  - Initialize (EventName As String)
    Turn off automatic collection by adding a new key to your project
    #PlistExtra: <key>FirebaseCrashlyticsCollectionEnabled</key><false/>
    Initializes the library inside the Application_Start function.
    You should initialize FirebaseAnalytics before initializing this library.
  - isCrashlyticsCollectionEnabled As Boolean
    Check if automatically report collection is enabled or not
  - Log (msg As String)
    Add custom log messages
    NOTE: To avoid slowing down your app, Crashlytics limits logs to 64kB and deletes older log entries when a session's logs go over that limit.
  - sendUnsentReports
    Send unsent reports
  - setCrashlyticsCollectionEnabled (enable As Boolean)
    Enable collection for select users by calling the Crashlytics data collection override at runtime. The override value persists across launches of your app so Crashlytics can automatically collect reports. To opt out of automatic crash reporting, pass false as the override value. When set to false, the new value does not apply until the next run of the app
  - SetUserID (ID As String)
    Set user identifiers
  - TestCrash
    Cause a Test Crash

Installation:

Download the latest libraries from here.
Download the attached Zip file.
Copy the .a and .h file to the local build server's Libs folder.
Then copy the XML file to the B4i library folder.
Copy the upload-symbols file to FirebaseCrashlytics.framework folder of your local build server.

Usage:

Follow firebase integration tutorial from here,
After initializing the firebase analytic library initialize this crashlytics library.
You have to build the project in Release Mode. Otherwise, the builder will not generate the dSYM which is needed for the library to work.

Enable opt-in reporting

B4X:

#PlistExtra: <key>FirebaseCrashlyticsCollectionEnabled</key><false/>

After building the project (Not possible from hosted builder):

Don't run the app after building. Open Terminal App.
Type, cd /path/to/your/project/directory
In my case, it is /Volumes/ExtendedSSD/B4iBuildServer/UploadedProjects/a888heh
Paste this following code to upload dSYM file to google server and hit enter,
../../Libs/FirebaseCrashlytics.framework/upload-symbols -gsp ./GoogleService-Info.plist -p ios ./Payload
Now run the app.
For testing the crash call FirebaseCrashlytics.TestCrash.
It may take few minutes to reflect on the firebase dashboard

Update 1.01: Added simulator support.
Update 2.0:

Based on the new SDK.
Added option to check if any crash happens during the last run.
Added option to check if there are any unsent crash reports.
Added option to manually send unsent crash reports.
Added option to delete unsent crash reports.
Added option to check if automatic report collection is enabled or not
Added option to toggle automatic report collection
Added option to send custom log to crashlytics

Great work with all these libraries !!!

marcick · May 12, 2020

Can already be tested with hosted builder ?

Erel · May 12, 2020

I've uploaded the Mac files.

I don't know how to include this line, Is it the path to GoogleService-Info?, What is this -p ios./Payload?.

I use hosted builder

Its not possible to upload dSYM from hosted builder

It's a pity because it detects the error very well, but it doesn't give information about it

Biswajit · May 14, 2020

Sorry I didn't understand.

angel_ · May 15, 2020

I was testing and Crashlytics detects the error, but it request to upload the dSYM

That is what this following code does,

Without dSYM its not possible to show the actual error message.

Hello,

Thanks for sharing this library! I've included & updated the required libraries but I'm getting the below error when I run either release or debug mode:

My active libs are on the right. Any ideas?

I've added simulator support. Download the library again and replace the files in your Libs folder.

andyr00d · May 17, 2020

Thank you but I'm still getting the same error. To confirm, I've updated the XML iFirebaseCrashlytics file you uploaded in the internal libraries, and I've placed the other files (.framework, .a & .h files) into the buildserver libs directory on my local mac, still getting (running your attached example.b4i solution):

B4X:

ld: warning: Could not find or use auto-linked framework 'FBLPromises'
Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_iFirebaseCrashlytics", referenced from:
      objc-class-ref in b4i_main.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)


Error: ** BUILD FAILED **


The following build commands failed:
    Ld /Users/andrew/Documents/B4iBuildServer/UploadedProjects/<user id>/Payload/B4i\ Example.app/B4i\ Example normal x86_64
(1 failure)

Biswajit · May 17, 2020

Maybe I've uploaded the previous version again. I've tested in simulator this time. Please download again. And remember to clear the project before running.

andyr00d · May 17, 2020

Confirmed that it works now, thank you

An update: it was working well for a while but after submitting some new builds and running the command to upload the DSYMs, it's now saying that they are missing. Couple of questions... Does the provision profile need to be the store/release one? I'm assuming that the DSYMs need to be uploaded after each build, but what if a slight amount of code was updated, then the app was re-build (keeping the same #Version) - will those generated DSYMs still be valid? I'm trying many different ways but can't get past the "Upload missing required dSYMs" - any ideas?

No. It can be anything.

For each and every build you have to submit that dSYM file. It doesn't matter if you changed a small amount of code or huge amount of code.

Did you upload the dSYM file after release build using the command line code posted above?

So what if I created a new build, uploaded to the App store and forgot to upload the DSYMs, and already modified some code and compiled a new debug build... can the previous (app store) version's DSYMs still be found? so the newly created build's DSYM's wouldn't be compatible and an entirely new build needs to be created for the App store?

Biswajit · Jun 15, 2020

You need xcode to download the dSYM file from app store. (Possible only if you uploaded the app using xcode)

Add your account to xcode from preference.
Goto Window > Organiser > Archives
Select your app from app list at the left side
Select version
Click on download debug symbols button

andyr00d · Jun 15, 2020

Actually I tried that already, but in archives only my original build version is showing (1.0), not the 1.07 which I uploaded to the App Store but I guess I can try it again with the DSYM from Xcode
