Build Android Arsenal

libphonenumber-kotlin

Kotlin Multiplatform port of MichaelRocks/libphonenumber-android

Why?

Ported to Kotlin Multiplatform to be used in common code for Android and iOS, macOS, and web!

Check out the Compose Multiplatform sample

Screen.Recording.2023-07-27.at.2.13.10.PM.mov

Note:

While the sample apps run on all targets, this project is experimental and is a work in progress. Only the JVM target has all tests passing, native and js have failing tests that need to be addressed.

Any help/PRs are appreciated!

TODO: Update the rest of the readme.

Google's libphonenumber is a great library but it has to major flaws when used on Android:

  1. It adds about 7k methods to a final dex. Not anymore, since 7.7.0.
  2. Internally the library uses Class.getResourceAsStream() method, which is very slow on Android.

The goal of this library is to fix these two issues.

Setup

Gradle:

repositories {
    mavenCentral()
    // For snapshots
    maven("https://s01.oss.sonatype.org/content/repositories/snapshots/")
}

dependencies {
    implementation("io.github.luca992.libphonenumber-kotlin:libphonenumber:0.1.1")
}

For DexGuard users

If your project is obfuscated with DexGuard you may need to add the following line to the DexGuard configuration:

-keepresourcefiles assets/io/michaelrocks/libphonenumber/android/**

API differences

This library is not fully compatible with the original libphonenumber.

  1. Every libphonenumber class is repackaged to io.michaelrocks.libphonenumber.android.
  2. PhoneNumberUtil doesn't contain a getInstance() method so you have to create an instance of this class with one of PhoneNumberUtil.createInstance() methods and store it somewhere.
  3. PhoneNumberUtil now has a createInstance(Context) method, which is a default way to obtain an instance of this class on Android.
