El campo de valor de Cadena # no está presente en las versiones de Android> = 6.0
Estoy creando una aplicación como Uber, pero me he encontrado con un problema después de que recibí un error de repente y la aplicación se bloqueó. Probé muchas formas para evitar este error, pero no funcionó. Todas las respuestas a las preguntas similares que pude encontrar en Stackoverflow fueron que este problema se debe aFirebaseDatabase.getInstance().setPersistenceEnabled(true) y tuve que eliminar este código de línea ya que este es un error con Firebase que aún no se ha resuelto. Pero esto no resolvió mi problema, ya que no tenía ese código. Es por eso que pensé que esta es una pregunta que no está en stackoverflow y formulé la pregunta. Este es mi código Java
