Android port of Google's libphonenumber.

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.

Gradle:

repositories {
  mavenCentral()
}
dependencies {
  implementation 'io.michaelrocks:libphonenumber-android:9.0.5'
}

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/**

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.
