我Proguard的條目的

建立警告

Error:warning: Ignoring InnerClasses attribute for an anonymous inner class 
Error:(c.a.a.g.b) that doesn't come with an 
Error:associated EnclosingMethod attribute. This class was probably produced by a 
Error:compiler that did not target the modern .class file format. The recommended 
Error:solution is to recompile the class from source, using an up-to-date compiler 
Error:and without specifying any "-target" type options. The consequence of ignoring 
Error:this warning is that reflective operations on this class will incorrectly 
Error:indicate that it is *not* an inner class. 

Answer 1

很難給出非常準確的答案，因爲你不顯示的代碼。

我假設你有地方這樣的代碼：

public class MyData {  
    private String id ; 
    private String email ;  
} 

然後：

MyData myData = ... ; 
databaseReference.push().setValue(myData); 

的問題是，邁德特被混淆。有2個可能的解決方案，那麼：

無論是防止邁德特混淆：

-keepnames class com.example.MyData 
-keepclassmembers class com.example.MyData {*;} 

或者有過什麼被送到火力一個更精細的控制：

public class MyData { 

    private String id ; 
    private String email ; 

    public Map<String, Object> toMap() { 
     Map<String, Object> map = new HashMap<>(); 
     map.put("id", id); 
     map.put("email", email); 
     return map ; 
    } 
} 

然後：

MyData myData = ... ; 
databaseReference.push().setValue(myData.toMap()); 

如果MyData被混淆，此解決方案應該工作。

希望這可以幫助你。
