Ngoài ra tôi đang sử dụng googlemap V2 trong ứng dụng của tôi

Answer 1

tôi nhận này sau khi cập nhật thư viện hỗ trợ Android để rev.18. Đã sửa lỗi bằng cách thêm:

-dontwarn android.support.v4.** 

vào tệp cấu hình ProGuard.

Answer 2

Như được chỉ dẫn bởi liên kết đến ProGuard Troubleshooting page trong nhật ký bảng điều khiển của bạn, bạn nên thay đổi mục tiêu trong project.properties thành mục tiêu chứa các lớp bị thiếu. Trong trường hợp này: "android-18" hoặc có thể "Google Inc.:Google APIs: 18".

Bạn vẫn có thể chỉ định một minSdkVersion khác trong AndroidManifest.xml.

Bạn nên không chỉ định bất kỳ tùy chọn -libraryjars nào, vì quá trình xây dựng Android đã chỉ định các tùy chọn đó cho bạn - bạn sẽ chỉ thấy cảnh báo về các lớp trùng lặp ngay bây giờ. Trong thực tế, quá trình xây dựng Android chỉ định hầu hết các tùy chọn khác cho bạn.

Answer 3

(tôi sử dụng Motodev Studio 4.1 và lần đầu tiên cho phép Proguard trong menu "Motodev")

Phương pháp một: Thêm dòng đầu tiên để tập proguard.cfg của bạn trực tiếp, có lẽ dòng thứ hai là cần thiết. .

-dontwarn android.support.v4 **

-dontskipnonpubliclibraryclassmembers

Một cách khác: theo các hướng dẫn Proguard-project.txt để loại bỏ "#" trước $ {} trong sdk.dir project.properties, sau đó thêm hai dòng trên trong Proguard-project.txt
