Por favor, ayuda a corregir estos errores. Debido a estos errores / advertencias, la compilación está finalizando.

Nota: El directorio de Android se está creando incluso después de estos errores. Pero creo que la biblioteca no se compila correctamente debido a los errores anteriores.

Avísame si necesitas algo más. Por favor ayuda.
