Hiragana Converter （ひらがな変換）

Summary

This is an Android app that uses gooラボ's API (Japanese Hiragana Conversion API) to convert Japanese strings, including kanji and alphabets, into hiragana/katakana.

Conversion example

-	text
Before	漢字とWORDを含む日本語文字列
After（Hiragana）	かんじと わーどを ふくむ にほんごもじれつ
After（Katakana）	カンジト ワードヲ フクム ニホンゴモジレツ

How to perform API communication within the app

1. Get your API key below.
   https://labs.goo.ne.jp/apiusage/

2. Add the following to the bottom of local.properties
apiKey=<API key obtained in 1.> （Example： apiKey=011222333333abcd）

Note

Mock flavor is provided, so if you want to simulate API communication using Mock, you can test it by setting a meaningless value (such as "AAA") in apiKey.
