An encrypted alternative to SharedPreferences. It's based on secure Room/SQlite and uses sqlcipher
You need an enum which implements ConfigKey to access values, eg.
public enum MyConfigKeys implements ConfigKey {
KEY_OBJECT_A, // your key A
KEY_STRING_B; // your key B ... and so on
}and init it with your secret
class MyApplication : Application() {
override fun onCreate() {
super.onCreate()
DbPreferences.init(this, "your secret")
}
...
}// get it
TestClass testClass = new DbPreferences().get(MyConfigKeys.KEY_OBJECT_A, TestClass.class);
// or save
new DbPreferences().put(MyConfigKeys.KEY_OBJECT_A, testClassToStore);// get
val testClass = DbPreferences().get<TestClass>(MyConfigKeys.KEY_OBJECT_A, TestClass::class.java)
//or save
DbPreferences().put(MyConfigKeys.KEY_OBJECT_A, testClassToStore)Handle a list
//save
DbPreferences().put(MyConfigKeys.KEY_LIST, listSource)
// get
val listType = object : TypeToken<ArrayList<TestClass>>() {
}.type
var myList: ArrayList<TestClass>? = DbPreferences().get(MyConfigKeys.KEY_LIST, listType)That's it !
