Power Preference

A Powerful library to control and simplify the usage of shared preference in Android.

Download

Step 1. Add the JitPack repository to your build file

allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
    }
}

Step 2. Add the dependency

implementation 'com.github.AliAsadi:PowerPreference:2.1.1'

Getting started

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

PowerPreference.init(this);

Access the Preference File

There are two ways to access the preference file:

1. Default File

This is the default file provided by the library.

Preference preference = PowerPreference.getDefaultFile();

2. Custom File

When you choose a file name, a new file with that name will be created.

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

Save Data

The library can store data in two ways. asynchronously and synchronously.

Also, The library can store any type of data.

Integer, Long, Float, Double, String, ArrayList, Map, Object are all valid data types.

Asynchronous

To write data to a preference file asynchronously, use methods that begin with the put prefix.

The thread you're working on will not be blocked.

• Insert single value

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

• Insert multiple values

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

Synchronous

To write data to a preference file synchronous, use methods that begin with the set prefix.

Until the save operation's result is received, the thread you're working on will be blocked.

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

Set can also be called with other types, such as setBoolean() and setObject().

Read Data

To retrieve data from a preference file, use methods that begin with the get prefix.

1. String

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

2. Object

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

3. Array

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

4. Map

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

Note:

If you don't specify a default value when calling get and the key you're looking for doesn't exist, the library will return default value from the list below.

For Example:

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

If you call get string without specifying a default value and the key does not exist, the library will return an empty string as a default value.

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.

Remove Data

• Synchronous

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

• Asynchronous

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

Clear Data

1. Clear data from specefic file

• Synchronous

PowerPreference.getDefaultFile().clear();

• Asynchronous

PowerPreference.getDefaultFile().clearAsync();

2. Clear data from all files

• Synchronous

PowerPreference.clearAllData();

• Asynchronous

PowerPreference.clearAllDataAsync();

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

Using the preference debugger, you can easily see and edit all of your app's preferences data.

PowerPreference.showDebugScreen();
