Android提供了一套很方便的進行資源（語言）國際化機制，為了更好地支持多語言，很多工程的翻譯往往會放到類似crowdin這樣的平臺上。資源是全了，但是還是會有一些問題。
哪些問題
以下使用一些語言進行舉例。其中values為工程默認的資源。
1.某語言的資源和某語言限定區域的資源之間。如values-fr-rCA存在于values-fr相同的字符串，這種表現最為嚴重。
2.某語言的資源和默認的資源之間。values-fr存在與values相同的字符串，可能原因是由于values-fr存在未翻譯字符串導致
為什么要去重
潔癖，容不下半點冗余。
解決思路
1.如果values-fr-rCA存在于values-fr相同的字符串，去除values-fr-rCA中的重復字符串，保留values-fr。這樣可以保證在values-fr-rCA下也可以正確讀取到資源。
2.如果values-fr存在與values相同的字符串。如去除values-fr中得重復字符串，保留values的條目。
