How to disable Crashlytics Answers?

问题:

Disabling Crashlytics error reporting is relatively straight forward.. I'd also like to disable Answers for debug builds. However,

new Crashlytics.Builder().answers(null);

doesn't work since apparently answers can't be null and

new Crashlytics.Builder().answers(new CustomAnswers());

with CustomAnswers being my class extending Answers gets me a NPE when calling Answers.getInstance(). But that approach is cumbersome to begin with compared to simply calling some enable() method.

Any ideas?

On a side note, I really hope Fabric is going to update and improve their docs soon.

回答1:

on my app we do it the old fashioned way:

if (!IS_DEBUG) {
   Fabric.with(this, new Crashlytics());
}

works fine.

Of course you can initialise with whichever custom parameters you need.

edit:

to get the debug boolean is just a matter of using gradle to your favour:

src/
   main/ // your app code
   debug/
       AppSettings.Java:
            public static final boolean IS_DEBUG = true;
   release/
       AppSettings.Java:
            public static final boolean IS_DEBUG = false;

edit:

I would advise against using BuildConfig.DEBUG, see this article: http://www.digipom.com/be-careful-with-buildconfig-debug/

For the time being, I solved the problem the old Java way:

Extend Answers using a sort-of singleton:

public class CustomAnswers extends Answers {

    private static CustomAnswers instance;

    private boolean mEnabled;

    private CustomAnswers(boolean enabled) {
        super();
        mEnabled = enabled;
    }

    public static synchronized void init(boolean enabled) {
        if (instance == null) {
            instance = new CustomAnswers(enabled);
        }
    }

    public static synchronized CustomAnswers get() {
        return instance;
    }

    @Override
    public void logSignUp(SignUpEvent event) {
        if (mEnabled) {
            super.logSignUp(event);
        }
    }

    // (...)
}

Initialize Crashlytics with Answers implementation:

boolean isDebug = DebugHelper.isDebugVersion(this);
CustomAnswers.init(!isDebug);
CrashlyticsCore crashlyticsCore =
        new CrashlyticsCore.Builder().disabled(isDebug).build();
Fabric.with(this, new Crashlytics.Builder()
        .core(crashlyticsCore).answers(CustomAnswers.get()).build());

Use Answers implementation for events:

CustomAnswers.get().logInvite(new InviteEvent());

This will disable events being logged.

Note that, as described in my first post, Answers.getInstance() will return null and not your CustomAnswers instance in that case.

Try this code

 CrashlyticsCore core = new CrashlyticsCore.Builder().disabled(BuildConfig.DEBUG).build();
Fabric.with(this, new Crashlytics.Builder().core(core).build());

or

Fabric.with(this, new Crashlytics.Builder().core(new CrashlyticsCore.Builder().disabled(BuildConfig.DEBUG).build()).build());
