Android - Crashlytics, run code during crash

问题

I had a bad crash case that was caused due to some Asyncs doing stuff in improper order in a SQLite and thing blew up. It took me some time to debug all that and access to the internal db would have helped immensely. I know how to access that internal db on a dev device but in case something goes wrong I would like to be able to get an instance of that db no matter the device. For error reporting I am using Crashlytics.

The question is: Is there a way to have Crashlytics run a piece of code (method, etc) during the crash collection/reporting? (For example, get db copy and email it, or something)

Couldn't find something in the documentation.

回答1:

It is possible to get control prior to Crashlytics logging a crash. You essentially have to create your own uncaught exception handler and call Crashlytics' handler from there. Something like this in your Application class:

private UncaughtExceptionHandler originalUncaughtHandler;

@Override
public void onCreate() {
    // initialize Fabric with Crashlytics

    originalUncaughtHandler = Thread.getDefaultUncaughtExceptionHandler();
    Thread.setDefaultUncaughtExceptionHandler(this);

    // do the rest of your oncreate stuff
}

@Override
public void uncaughtException(Thread thread, Throwable ex) {
    // do your work to add data to Crashlytics log

    originalUncaughtHandler.uncaughtException(thread, ex);
}

No you can't. You can however set certain values before initiating Crashlytics. Like adding values to parameters so as to identify user. Like adding email id of user before creating a crashlytics session.

As @basu-singh said, you can add context to the crash, see https://docs.fabric.io/android/crashlytics/enhanced-reports.html

Or you can use your own UncaughtExceptionHandler, and then call Crashlytics. Though your code needs to be extra safe !
