Je crée une application comme Uber, mais j'ai rencontré un problème après une erreur soudaine et l'application est tombée en panne. J'ai essayé de nombreuses manières pour surmonter cette erreur, mais cela n'a pas fonctionné. Toutes les réponses aux questions similaires que j'ai pu trouver sur Stackoverflow étaient que ce problème était dû à FirebaseDatabase.getInstance().setPersistenceEnabled(true) et que je devais supprimer ce code de ligne car il s'agit d'un bogue avec Firebase qui n'a pas encore été résolu. Mais cela n'a pas résolu mon problème car je n'avais pas de tel code. C'est pourquoi j'ai pensé que c'était une question qui n'était pas sur stackoverflow et j'ai posé la question. Ceci est mon code Java

Vous pouvez ajouter la ligne suivante dans AndroidManifest.xml: 

<uses-library Android:name="org.Apache.http.legacy" Android:required="false"/>

J'ai eu un problème similaire, qui a été résolu en l'exécutant dans un émulateur avec Google Play activé et mis à jour. En gros, créez un nouveau périphérique virtuel doté de Google Play (pas uniquement de Google API).

Voir Cette question pour plus de détails.

Utilisez com.firebase:geofire-Android:2.1.1. Peut-être que c'est un problème de version. Cela a résolu le problème pour moi.
