Xamarin形式的java.exe「退出，代碼爲1（ProGuard的）

Question

我有問題，與我ProGuard的形式Xamarin的項目，我有以下錯誤：的java.exe」，代碼1

和多個警告退出如：okio.Okio：找不到引用的類java.nio.file.Path

我已經嘗試了許多解決方案，例如：

• 下載最新版本的Proguard的，並且在替換它規格c文件夾。
• 設置我的Java最大堆大小達到1G
• 創建我自己的proguard.cfg並設置生成操作ProguardConfiguration

這些解決方案都在工作，我已經嘗試過多種清潔和建設，以及。 但有一件事很奇怪，我可以在我的鏈接設置爲「無」而不是「僅限SDK組件」時構建我的項目。當啓用ProGuard並將我的鏈接設置爲SDK組件時，它不起作用，是否正常？

這是我的輸出構建的例子：

這些都是我的警告：

我應該怎麼辦？我不知道如何解決這個問題..

Answer 1

發佈您的警告error.Also在您的progaurd.pro文件中添加一些行。

-keep class org.apache.http.** { *; } 
-dontnote org.apache.http.** 
-dontwarn org.apache.http.** 
-dontwarn android.net.* 

Answer 2

嘗試升級JDK

https://bugzilla.xamarin.com/show_bug.cgi?id=44187

Xamarin穩定15.2是不是穩定的，因爲它應該:)

Answer 3

我用Square.Picasso庫我Xamarin.Android項目沒有問題並使用鏈接設置到SDK和用戶組合。

我ProGuard的配置文件中包含的：

-dontwarn org.codehaus.** 
-dontwarn java.nio.file.** 
-dontwarn com.square.** 
-dontwarn okio.** 
-keep public class android.support.v7.widget.FitWindowsLinearLayout 
-keep public class android.support.design.widget.AppBarLayout 

你說，你在你的Android SDK有最新的ProGuard版本，所以它應該工作！
