OpenCSVを組み込んだところ、コンパイルは通るものの以下のようなエラーが発生するようになった。
使用しているAndroid Studioのバージョンは、2.2.3です。
目次
原因
インナークラスのorg.apache.commons.collectionsの中で何かが起きているようで、再コンパイルを求められているようです。
そんなことは難しいので、これに反応しているProGuardを無効してしまいましょう。

appのbuild.gradle内にあるbuildTypesのdebugとreleaseのminifyEnabledをtrueに変更します。
buildTypes {
debug
{
minifyEnabled true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
release
{
minifyEnabled true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}これで、proguard-rules.proに記述したProGuardの設定が有効になります。
次にproguard-rules.proへインナークラスに関するエラーが発生しないように設定します。
-keepattributes InnerClassesコンパイルし直して、エラーが発生しないか確認します。
OpenCSVの場合、これだけでは収まりませんでした。
発生している箇所をProGuardに追加設定します。
-dontwarn com.opencsv.bean.*
-dontwarn org.apache.commons.*
-dontwarn org.apache.commons.beanutils.*
-dontwarn org.apache.commons.collections.*
-dontwarn org.apache.commons.beanutils.locale.*私の環境では、これでエラーが発生しなくなりました。
以上、インナークラスが原因でProGuardからエラーが発生する場合の対処法についてでした。
