Android provides many ways of storing data of an application. One of these ways is called Shared Preferences. Shared Preferences allow you to save and retrieve data in the form of key, value pair.
Here I share a simple custom SharedPreferences.kt class that can be used for every Android application if needed.
import android.content.Context
import android.content.SharedPreferences
import com.securepreferences.SecurePreferences
/**

class SharedPreference(val context: Context) {
private val PREFS_NAME = "your_app_preference_name"
private val sharedPref: SharedPreferences =
context.getSharedPreferences(PREFS_NAME, Context.MODE_PRIVATE)
fun save(KEY_NAME: String, text: String) {
val editor: SharedPreferences.Editor = sharedPref.edit()
editor.putString(KEY_NAME, text)
editor.commit()
}
fun save(KEY_NAME: String, value: Int) {
val editor: SharedPreferences.Editor = sharedPref.edit()
editor.putInt(KEY_NAME, value)
editor.commit()
}
fun save(KEY_NAME: String, status: Boolean) {
val editor: SharedPreferences.Editor = sharedPref.edit()
editor.putBoolean(KEY_NAME, status)
editor.commit()
}
fun getValueString(KEY_NAME: String): String? {
return sharedPref.getString(KEY_NAME, null)
}
fun getValueInt(KEY_NAME: String): Int {
return sharedPref.getInt(KEY_NAME, 0)
}
fun getValueBoolien(KEY_NAME: String, defaultValue: Boolean): Boolean {
return sharedPref.getBoolean(KEY_NAME, defaultValue)
}
fun clearSharedPreference() {
val editor: SharedPreferences.Editor = sharedPref.edit()
//sharedPref = PreferenceManager.getDefaultSharedPreferences(context);
editor.clear()
editor.commit()
}
fun removeValue(KEY_NAME: String) {
val editor: SharedPreferences.Editor = sharedPref.edit()
editor.remove(KEY_NAME)
editor.commit()
}
}You can find the Github repo for this class here
