Android counter part of the RSFlags iOS library

Lightweight android library for getting flag image for any country

This entire library is only 175 kb. Can you believe that?

Simple, no nonsense, lightweight library for getting flag icon for any country from the two character country code

How this differs from other libraries?

There are plenty of open source libraries available for getting the flag icon. But they all include separate image or vector files for each country (there are more than 250 flags in the world) hence become bulky.

Unlike all the other libraries, this one includes only ONE sprite image which consists of all the icons of all the flags. And the icons are sliced from the sprite image when requested.

Demo

Usage

Simple Use

FlagDrawableProvider flagProvider = new Flags.Builder(context)
											 .build();
BitmapDrawable usFlag = flagProvider.forCountry("US")

That is all

Supply your own source image

By default, the flags library uses a 94 kb sprite image with flag icons with size of 32 x 22.

In some cases, this may not be suitable for you. So you can supply your own sprite image with a higher resolution for cases like that.

This is how you supply your source image. Make sure you also give the correct height and width of flag tiles.

FlagDrawableProvider largeFlagProvider = new Flags.Builder(this)
                .setSourceImage(getImageFromAssetsFile(this, "flags_sprite_big.png"))
                .setTileWidth(320)
                .setTileHeight(220)
                .build();

How to include

As a dependency

1. Add the JitPack repository to your build file Add it in your root build.gradle at the end of repositories:

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

2. Add the dependency

dependencies {
  implementation 'com.github.jsramraj:flags:$version'
}

Just replace the $version with the appropriate version number, for e.g v1.0

Direct include

If, for some reason, you are not okay with adding a entire library, you can still use this by just adding two files into your project.

• Give this library a star
• Drag the sprite image that consists of all the flag icons into your project's asset folder
• Add the Flags class to your project

That is all!!! you are good to go.

Want high res icons?

This library is created to occupy very minimum space. So each flag size is only 32x22. If you want a higher resolution image, all you have to do is give a higher resolution image to this library.

You can use my another tool flag-sprite-creator to create higher resolution sprite image. Find our more about the tool here. The tool is deployed in heroku, you can find it here
