project.properties で「proguard.config=${sdk.dir}/tools/proguard...」をコメントアウトして proguard を無効にしている場合、私のアプリはデバッグ中、および署名付き apk にエクスポートするときにも正常に動作します。

ただし、その行のコメントを外すと、たくさんの警告が表示され、proguard は apk を作成しません。次の行を proguard-project.txt に追加することで、警告を抑制することができます

-dontwarn com.sun.mail.imap.protocol.**
-dontwarn org.apache.harmony.awt.**
-dontwarn javax.activation.**

apk は作成されますが、電話では実行されません。興味深いことに、これらの行を削除して「-dontshrink」を使用すると、引き続きこれらのエラーが発生します。そうすれば問題は解決すると思っていました。

http://developer.android.com/tools/help/proguard.htmlで、構成にいくつかの -keep 行が欠落している可能性があることがわかりましたが、これらが何であるかは明らかではありません。誰でも手がかりを提供できますか？

デフォルトの proguard.cfg ファイルは一般的なケースに対応しようとしますが、ClassNotFoundException などの例外が発生する可能性があります。これは、アプリケーションが呼び出すクラス全体を ProGuard が取り除くときに発生します。

proguard.cfg ファイルに -keep 行を追加することで、ProGuard がコードを削除する際のエラーを修正できます。例えば：

-公開クラスを維持する

少し遅いかもしれませんが、同様の問題の解決策を探していると、ライブラリ jar にいくつかのクラスを保持するようにproguardに指示する必要があることがわかりました。Warning: ...および と記載されているログを参照してくださいcan't find referenced class ...。

したがって、あなたの場合は次のようになります。

-keep class javax.security.** { *; }
-keep class java.beans.** { *; }
-keep class java.awt.** { *; }

と

-libraryjars libs/XYZ.jar

/libsそれらのクラスを含むすべてのjarに対して。
