由于某些.jar依赖性，无法使用ProGuard编译应用的发行版本

标签： android android-gradle dependencies proguard zebra-printers

我最近将Zebra Scanner SDK添加到了我的Android应用中（通过ZSDK_ANDROID_API.jar依赖项）。进行调试编译（不使用ProGuard）可以正常工作。但是，当我使用ProGuard进行发行版编译时，出现以下错误：

我尝试将-keep class com.zebra.sdk.** { *; }添加到我的proguard-rules.pro文件中，但这也不起作用。

这是我的应用程序的Gradle文件：

您应该在Java编译器部分中解决警告。 对我来说，这有助于将其添加到我的ProGuard配置文件中：

-dontwarn org.apache.**
-dontwarn uk.co.westhawk.**
-dontwarn au.com.bytecode.**
-dontwarn com.zebra.**
-dontwarn com.fasterxml.**

-keep class org.apache.** { *; }
-keep interface org.apache.** { *; }
-keep class uk.co.westhawk.** { *; }
-keep interface uk.co.westhawk.** { *; }
-keep class au.com.bytecode.** { *; }
-keep interface au.com.bytecode.** { *; }
-keep class com.zebra.** { *; }
-keep interface com.zebra.** { *; }
-keep class com.fasterxml.** { *; }
-keep interface com.fasterxml.** { *; }

我在Visual Studio 15.9.18中有一个Xamarin.Android应用程序构建。这是我最小的proguard.cfg文件，以使发布版本有效：

-dontwarn mono.com.symbol.emdk.**
-dontwarn com.symbol.emdk.**

-keep class mono.com.symbol.emdk.** { *; }
-keep interface mono.com.symbol.emdk.** { *; }
-keep class com.symbol.emdk.** { *; }
-keep interface com.symbol.emdk.** { *; }

注意事项1：如果仅将文本文件添加到VS中的项目中，它将创建一个开头为BOM (byte order mark)的文件。生成时，您会收到一条有用的描述性错误消息，如error MSB6006: "java.exe" exited with code 1。解决方案是确保您的proguard.cfg是不带BOM的纯文本文件。这就是为什么我们不能拥有美好的事物。

注意事项2：仅将proguard.txt文件添加到项目中是不够的。记住，您必须右键单击该文件，然后将“属性”->“构建操作”设置为ProguardConfiguration。

注意事项3：我的特定应用仅使用Zebra EMDK的条形码扫描仪位。如果您正在使用其他东西，请使用YMMV。

注意事项4：请记住，在Xamarin + VS中，Proguard使用的是obj\Release\proguard\proguard_xamarin.cfg中的proguard.cfg plus 默认配置。有关详细信息，请参见the official docco。
