How to disable Firebase Crash Reporting when the app is running on debug?

Question

I have successfully implemented Firebase Crash Reporting, but I need to disable the service when the app is running undo the \'debug\' Build Variant, in order to avoid non-r

Answer 1

Inspired by this related answer and others here, I came up with this handy solution.

Using Timber for logging, I created different implementations of a Tree subclass for debug and release builds. In debug, it defers to DebugTree which writes to logcat. In release, it forwards exceptions and high-priority logs to Firebase, dropping the rest.

build.gradle

dependencies {
  ...
  compile 'com.jakewharton.timber:timber:4.3.0'
  releaseCompile 'com.google.firebase:firebase-crash:9.0.2'
}

src/debug/java/[package]/ForestFire.java

import timber.log.Timber;

public class ForestFire extends Timber.DebugTree {}

src/release/java/[package]/ForestFire.java

import android.util.Log;
import com.google.firebase.crash.FirebaseCrash;
import timber.log.Timber;

public class ForestFire extends Timber.Tree {
  @Override
  protected void log(int priority, String tag, String message, Throwable t) {
    if (Log.WARN <= priority) {
      FirebaseCrash.log(message);
      if (t != null) {
        FirebaseCrash.report(t);
      }
    }
  }
}

App startup

Timber.plant(new ForestFire());
