Better SharedPreferences wrapper, like SwiftyUserDefaults
KPreferences is a Kotlin wrapper for Android SharedPreferences, to make it simpler and safer (avoiding null problems at compile time thanks to Kotlin)
val stringPrefs = KStringKey("name", "def")
val str = prefs[stringPrefs] // This is a string
val intPrefs = KIntKey("name", 1)
val int = prefs[stringPrefs] // This is an integerval stringPrefs = KStringKey("name", "def")
prefs[stringPrefs] = "foo" // Calls SharedPreferences.Editor#apply() immediately
prefs.edit {
this[stringPrefs] = "bar"
} // Calls SharedPreferences.Editor#apply() after block executedval stringPrefs = KStringKey("name", "def")
if (stringPrefs in prefs) {
// Check if SharedPreferences contains this key
}
if ("keyString" in prefs) {
// Check if SharedPreferences contains this key
}val nullableStringPrefs = KNullableStringKey("name", null)
val str = prefs[nullableStringPrefs] // This is a nullable stringclass KDateKey(key: String, def: Date) : KSimpleKey<Date>(key, def) {
