Report Custom events to Crashlytics without actually killing the process.

CrashReporting

public class CrashReporting {

  public static class GenericReportingException extends Exception {
      public GenericReportingException(){}
  
      public GenericReportingException(String str){
        super(str);
      }
  }

  /**

    if(exception == null) return;
    
    Thread.getDefaultUncaughtExceptionHandler().uncaughtException(Thread.currentThread(), exception);
  }
}

MyApp.java

public class MyApp extends Application {
  @Override
  public void onCreate() {
    super.onCreate();
    //Must init in this order
    installCrashHandler();
    startCrashlytics();
  }
  
  /**
   * initialized Crashlytics with this Application Object Context
   **/   
  private void startCrashlytics() {
    Crashlytics.start(getApplicationContext());
  }
  
  /**
   * installed a custom Crash Handler that will not actually crash the app using a GenericReportingException object
   **/
  private void installCrashHandler() {
    private void installCrashHandler(){
    //The real UncaughtExceptionHandler
    final Thread.UncaughtExceptionHandler realExceptionHandler = Thread.getDefaultUncaughtExceptionHandler();
    
    Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
      @Override
      public void uncaughtException(Thread thread, Throwable ex) {
        if(ex instanceof CrashReporting.GenericReportingException) {
          //Starting this again because it is unregistered on the completion of Crashlytics UncaughtExceptionHandler
          startCrashlytics();
          return;
        }
        
        realExceptionHandler.uncaughtException(thread, ex);
      }
    }
  }
}

I am not able to get method Crashlytics.start(this);
I guess this one is deprecated in latest build.
I am using Crashlytics - 2.5.1
