Android obfuscation compilation, the use of gson-2.2.2.jar reflection parsing json data, ClassCastException error, gson parsing json
In my code, I use the following methods:

public synchronized <T> T parseJson(String json, Class<T> classOfT) throws Exception{                T target = null;        Gson gson = new Gson();        target = gson.fromJson(json, classOfT);        return target;    }

The following method is used in my Activity:

String addModel = JsonParse. getJsonParse (). parseJson (jsonString, AddModel. class );
// Here, AddModel is a self-written model class.
// JsonString is a local file, which exists in Json format.
 

After compilation, the following error occurs: shortMsg: java. lang. ClassCastException.
LongMsg: java. lang. ClassCastException: com. google. gson. internal. StringMap
StackTrace: java. lang. ClassCastException: com. google. gson. internal. StringMap

At dalvik. system. nativeStart. main (Native Method) is a solution that uses Gson reflection to parse json strings. After obfuscation, the member variables of the Model change, resulting in the member variable name not matching the json string: in proguard. in the cfg file, we first declare that we should not confuse the corresponding Model class, for example, AddModel:

-keep public class com.android.chebaob.model.AddModel{    *;}

In addition, add the following content at the end of the proguard. cfg file:

##---------------Begin: proguard configuration for Gson  ----------# 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.** { *; }##---------------End: proguard configuration for Gson  ----------

 

This will solve the problem.
