Add to your project:

dependencies {
    ...
    implementation 'com.github.coletz:sharedprefdao:0.1.1'
    kapt 'com.github.coletz:sharedprefdao:0.1.1'
    ...
}

Don't forget to apply plugin: 'kotlin-kapt' and add maven { url "https://jitpack.io" } to your repositories

Usage:

  1. Annotate an interface with @SharedPrefDao
  2. Add var for each key you want in your Dao
  3. Set default values for your entries with @get:DefaultValue("myDefaultValue")
  4. In order to set an empty string as default value, use EMPTY_STRING constant;
@SharedPrefDao(name = AppConfig.SHARED_PREF_NAME)
interface SettingsDao {

    @get:DefaultValue("5")
    var volume: Int?
    @get:DefaultValue("PlayerOne")
    var username: String?

sharedprefdao's Issues

Avoid using String as "defaultValue" type

right now we are using String for defaultValue type, so we have "true" or "false" for boolean value or "1", "0.0" etc. for numeric values.
We should use Any type or implement multiple properties like defaultBoolean, defaultInt, defaultDouble etc. in order to improve type safety and avoid possible issue (like misspelling or confusion between dot and comma for decimal numbers)

Handle List objects

Handle also list objects (at least List, would be nice to handle also primitives and even better of serializable objects).
To save/extract a list of string it is enough to add a separator (which should be customizable);
This has bad performances, but can be pretty handy for short lists
