Android Proguard bỏ qua jar bên ngoài

Tôi đã cố gắng sử dụng Proguard trong dự án Android của mình, tôi thiết lập Proguard bằng cách sử dụng dòng lệnh 'android update project/path/to/project' và tệp proguard.cfg được tạo trong thư mục gốc của dự án. (Trong Eclipse của tôi với Android 2.3 sdk, khi tạo một dự án mới, tệp proguard.cfg không được tạo tự động vì vậy tôi phải thêm nó theo cách thủ công bằng cách sử dụng dòng lệnh).Android Proguard bỏ qua jar bên ngoài

Khi tôi xuất dự án, tôi đã nhận các lỗi sau đây

Những thông báo lỗi chỉ với bốn lọ bên ngoài được sử dụng trong dự án của tôi

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

đây là tệp proguard.cfg của tôi

Tôi đã thử một số giải pháp được tìm thấy trên web bằng cách thêm tùy chọn '-libraryjars', ví dụ:

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

nhưng nó sẽ không giúp đỡ.

Bất kỳ giải pháp nào?

Lọ thư viện của bạn tham khảo thêm các lọ thư viện (Mortbay, SLF4J, Apache Commons Logging, Log4j, ...) Thêm các lọ này với tùy chọn '-libraryjars' bổ sung sẽ giải quyết được vấn đề.

Nếu bạn hoàn toàn chắc chắn rằng mã của bạn không sử dụng các thư viện này, bạn có thể chỉ định '-giảm giá trị' hoặc '-duyển đổi', ví dụ:

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

Xin chào Eric, thanx cho giải pháp. Tôi đã thêm thư viện -larsjars vào thư viện mà bạn đã chỉ ra: các thông báo cảnh báo biến mất nhưng khi tôi chạy ứng dụng bị đóng, từ các thông điệp tường trình tôi tìm thấy 'ngoại lệ classnotfound' trên twitter4j –

thử thêm lớp gây ra "ClassNotFoundException" để các tùy chọn "giữ" '-keep public class com.example.Foo {public protected *; } ' –

bạn sẽ sử dụng đường dẫn nào trong tùy chọn -libraryjars? Tôi không thể hình dung ra điều đó. – cottonBallPaws
