下面是我的proguard-project.txt文件，取自

我的libs目录包含所需的库

我不明白为什么会出现这些错误？

我可以看出您在Gson和protobuf方面存在问题。 要将Gson与proguard一起使用，请在proguard-project.txt文件中包含填充行：

# 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.** { *; }

整个例子都可以找到

要修复protobuf错误，请尝试：

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

我已经放置了示例文件，但仍然收到警告。请尝试取消注释-keep class com.google.gson.stream.*{；}并更改特定于项目的模型类名称：更改此->-keep class com.google.gson.examples.android.model.*{；}

# 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.** { *; }

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