implementation 'com.aliassadi:power-preference-lib:1.4.1'

Getting started

Initialize the library in your Application.onCreate() method:

PowerPreference.init(this);

To accsess preference file there is two option:

1. Default file.

Preference preference = PowerPreference.getDefaultFile();

2. Specefic file.

Preference preference = PowerPreference.getFileByName("preferenceName");

Save Data - Asynchronous(PUT)

To write data to preference file asynchronous.

1. Insert single value

PowerPreference.getDefaultFile().putString("key",value);

2. Insert multiple values

PowerPreference.getDefaultFile()
        .putString("key", value)
        .putObject("key", value)
              .
              .
        .putMap("key", value);

Put will asynchronously save the preferences without holding the current thread.

The library support the default implementation of shared preference such as putBoolean() and putString().

Note:

You can write any type of data Integer, Long, Float, Double, String, ArrayList, Map, Object

Save Data - Synchronous(SET)

To write data to preference file synchronous.

Set will synchronously save the preference while holding the current thread until done and returning a success flag.

boolean result = PowerPreference.getDefaultFile().setString("key",value);

You can also call set with the type such as setBoolean() and setObject().

Read Data

To retrieve values from a preference file, call methods such as getInt() and getString(),

1. String

String value = PowerPreference.getDefaultFile().getString("key", defaultValue);

2. Object

Object value = PowerPreference.getDefaultFile().getObject("key", Object.class, defaultValue);

3. Array

ArrayList<Object> value = PowerPreference.getDefaultFile().getObject("key", Object[].class, defaultValue);

4. Map

HashMap<String, Object> value = PowerPreference.getDefaultFile().getMap("key", HashMap.class, String.class, Object.class);

Note:

You can getting a value with out pass a defaultValue the library well return a default from the list if the key not exist.

String value = PowerPreference.getDefaultFile().getString("key");

If the key dosn't exist the library will return an empty string.

Type	Default
Integer, Long, Float, Double	0
String	""
Object	null

You also can choose a default value for each key in you preference file by seDefaults() method see the defaults section for more.

Clear Data

1. Clear data from specefic file

PowerPreference.getDefaultFile().clear();

2. Clear data from all files

PowerPreference.getAllData()

Remove Data

PowerPreference.getDefaultFile().remove("key");

Get Data

1. Get all data for a specefic file

Map<String, ?> data = PowerPreference.getDefaultFile().getData();

2. Get all data for all files in the app.

List<PreferenceFile> data = PowerPreference.getAllData()

Default Values

Set Default value to be used when reading from shared preference, You can use a different defaults value for every preference file.

There is two option using:

1. XML

<?xml version="1.0" encoding="utf-8"?>
<defaultMap>
    <entry>
        <key>key</key>
        <value>true</value>
    </entry>

    <entry>
        <key>key</key>
        <value>Hello World!</value>
    </entry>
    
    <entry>
        <key>key</key>
        <value>5</value>
    </entry>
    
    //...etc
    
</defaultMap>

PowerPreference.getDefaultFile().setDefaults(R.xml.preferences_defaults)

2. HashMap

Map<String, Object> defaults = new HashMap<>();
defaults.put("key", true);
defaults.put("key", "Hello World!");
defaults.put("key", 123);
defaults.put("key", 111L);
defaults.put("key", 1.1f);
defaults.put("key", 1.111d);
defaults.put("key", new Object());

PowerPreference.getDefaultFile().setDefaults(hashMap);

Preference Debbuger

By preference debugger you can show all the preference in all the file in your app simply by calling.

PowerPreference.showDebugScreen();
