以下是我的proguard-project.txt文件，取自here

-injars      libs
-outjars     bin/classes-processed.jar

    public void set*(...);
}

-keepclasseswithmembers class * {

   public void *(android.view.MenuItem);
}

-keepclassmembers class * implements android.os.Parcelable {
    static ** CREATOR;
}

-keepclassmembers class **.R$* {
    public static <fields>;
}

-keepclassmembers class * {
    @android.webkit.JavascriptInterface <methods>;
}

我在project.properties文件中取消注释了这一行

proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

我的libs目录包含所需的库

我不明白为什么我会收到这些错误？

Answer 1

我可以看到你有Gson和protobuf的问题。 为了使用带有proguard的Gson，在proguard-project.txt文件中包含了填充行：

# Gson uses generic type information stored in a class file when working with fields. Proguard
# removes such information by default, so configure it to keep all of it.
-keepattributes Signature

# For using GSON @Expose annotation
-keepattributes *Annotation*

# Gson specific classes
-keep class sun.misc.Unsafe { *; }
#-keep class com.google.gson.stream.** { *; }

# Application classes that will be serialized/deserialized over Gson
-keep class com.google.gson.examples.android.model.** { *; }

可以找到整个示例here

为了解决protobuf错误，请尝试：

 -keep class com.google.protobuf.** { *; }
