QuickUtils

This repository offers a set of random useful classes to deal with repetitive tasks in the Android Framework. Intended to help you getting your Android applications off the ground quickly, by offering ready-to-use components and utility classes that wrap a lot of the boilerplate that’s involved when writing Android apps.

Main features

• REST - Simple REST requests and automatic parse
• Cache Magic - Easily serialize and cache your objects to disk using key/value pairs
• Async Image Loader - Image downloading and caching

Installation

Including in your project via Gradle:

dependencies {
    compile 'com.cesarferreira.quickutils:library:2.+'
}

Usage

Init the library in your Application class

public class SampleApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        QuickUtils.init(this);
    }
}

REST

Simple REST requests and automatic parse

Gson Entity

public class Tweet {
    @SerializedName("title")
    public String title;
    @SerializedName("amount_of_retweets")
    public long retweetsTotal;
}

The Request

 QuickUtils.rest.connect()
            .GET() // POST() // PUT()
            .load("https://path/to/the/tweets")
            .as(new TypeToken<List<Tweet>>() {})
            .withCallback(callback);

Post with Header and Body params

Header requestHeader = new Header.Builder()
                .add("Authorization", "Bearer Jhahdau2819ajsbdkasdkasdkashjdkahs")
                .build();

Body requestBody = new Body.Builder()
            .add("email", "john.doe@gmail.com")
            .build();

QuickUtils.rest.connect()
            .POST(requestHeader, requestBody)
            .load(url)
            .as(new TypeToken<List<Person>>() {})
            .withCallback(callback);

Cache magic!

Easily serialize and cache your objects to disk using key/value pairs.

Save

sync

QuickUtils.cacheMagic.save("somePerson", new Person("john doe"));

async

QuickUtils.cacheMagic.save("somePerson", new Person("john doe"), new SaveToCacheCallback() {(...)});

Read

sync

QuickUtils.cacheMagic.read("somePerson", null);

async

QuickUtils.cacheMagic.readAsync("somePerson", new TypeToken<Person>() {}, new ReadFromCacheCallback<Person>() {(...)});

Delete

QuickUtils.cacheMagic.delete("somePerson"); // deleteAsync also works

Erases ALL the key/values that are stored

QuickUtils.cacheMagic.deleteAll();

Exists

Check if a key/value exists

boolean personExists = QuickUtils.cacheMagic.existsKey("somePerson");

Async Image Loader

Image downloading and caching

// Simple
QuickUtils.imageCache.load(IMAGE_URL, imageView);

// or more complete
QuickUtils.imageCache.load(IMAGE_URL, imageView, R.drawable.dummy, R.drawable.error);

Using the util methods

All you need to do is to specify the category and the method you want to use.

QuickUtils.__category__.__method__

E.g.

// Log something
QuickUtils.log.e("this is an error");
// Make the smartphone vibrate for the amount of time you want
QuickUtils.system.vibrate(1000);
// Convert pounds to KG
QuickUtils.math.poundsToKg(weight);
// Does that file exists?
QuickUtils.sdcard.exists(someFile);
// Encode a string
QuickUtils.security.encodeBase64(someString);
// Save data
QuickUtils.prefs.save(key, value);
// Retrieve saved data
QuickUtils.prefs.getString(key, defaultValue);
QuickUtils.prefs.getInt(key, defaultValue);
// Remove saved data
QuickUtils.prefs.remove(key);
//  Etc. (hundreds more methods)
