AndroidプロジェクトでProguardを使用しようとしましたが、コマンドライン「androidupdateproject / path / to / project」を使用してProguardをセットアップし、ファイルproguard.cfgがプロジェクトのルートディレクトリに作成されました。（Android 2.3 SDKを使用するEclipseでは、新しいプロジェクトを作成するときに、proguard.cfgファイルが自動的に作成されないため、コマンドラインを使用して手動で追加する必要があります）。

プロジェクトをエクスポートすると、次のエラーが発生しました

これらのエラーメッセージは、私のプロジェクトで使用されている4つの外部jarを示しています

（.classpath）

<classpathentry kind="lib" path="/Users/lorensiuswlt/Android/android-sdk-mac_x86/libs/Twitter/signpost-commonshttp4-1.2.1.1.jar"/>
        <classpathentry kind="lib" path="/Users/lorensiuswlt/Android/android-sdk-mac_x86/libs/Twitter/signpost-core-1.2.1.1.jar"/>
        <classpathentry kind="lib" path="/Users/lorensiuswlt/Android/android-sdk-mac_x86/libs/Twitter/signpost-jetty6-1.2.1.1.jar"/>
        <classpathentry kind="lib" path="/Users/lorensiuswlt/Android/android-sdk-mac_x86/libs/Twitter/twitter4j-core-2.1.6.jar"/>

これが私のproguard.cfgファイルです

-dontskipnonpubliclibraryclasses

'-libraryjars'オプションを追加して、Webで見つかったいくつかの解決策を試しました。例：

-libraryjars /Users/lorensiuswlt/Android/android-sdk-mac_x86/libs/Twitter/twitter4j-core-2.1.6.jar

しかし、それは役に立ちません。

解決策はありますか？

ライブラリ jar は、さらに多くのライブラリ jar (Mortbay、SLF4J、Apache Commons Logging、Log4j など) を参照しています。これらの jar に追加の「-libraryjars」オプションを追加すると、問題が解決するはずです。

コードでこれらのライブラリを使用していないことが確実な場合は、'-ignorewarnings' または '-dontwarn' を指定できます。

-dontwarn org.mortbay.**
-dontwarn org.slf4j.**
-dontwarn org.apache.log4j.**
-dontwarn org.apache.commons.logging.**
-dontwarn org.apache.commons.codec.binary.**
