SASS - Important Notes

Sass files beginning with an underscore are called partials and won't be compiled to CSS, but they can be imported into other sass stylesheets.

@SerializedName and @Expose annotations

The  @SerializedName  annotation is needed for Gson to map the JSON keys with our fields. In keeping with Java's camelCase naming convention for class member properties, it is not recommended to use underscores to separate words in a variable.  @SerializedName  helps translate between the two. @SerializedName ( "quota_remaining" ) @Expose private Integer quotaRemaining; In the example above, we are telling Gson that our JSON key  quota_remaining  should be mapped to the Java field  quotaRemaining .  If both of these values were the same, i.e. if our JSON key was  quotaRemaining  just like the Java field, then there would be no need for the  @SerializedName  annotation on the field because Gson would map them automatically. The  @Expose  annotation indicates that this member should be exposed for JSON serialization or deserialization.
