// Example of using DataStore in Android with a simple preferences implementation
// 1. Adding dependencies in build.gradle
dependencies {
implementation "androidx.datastore:datastore-preferences:1.0.0"
}
// 2. Creating DataStore instance
private val dataStore: DataStore = context.createDataStore(name = "settings")
// 3. Storing data
suspend fun saveUserName(name: String) {
dataStore.edit { preferences ->
preferences[stringPreferencesKey("user_name")] = name
}
}
// 4. Retrieving data
val userNameFlow: Flow = dataStore.data
.map { preferences ->
preferences[stringPreferencesKey("user_name")] ?: "No name"
}
// 5. Collecting data (In a Coroutine)
lifecycleScope.launch {
userNameFlow.collect { userName ->
// Use the retrieved user name
Log.d("UserName", userName)
}
}
