android-将数据保存到firebase用字母键保存

Question

my data is saved to firebase this way:

a: "Tom"
b: "26"
...

I know that in order to save it with the correct keys ("mName" instead of "a", "mAge" instead of "b" and so on) I have to add the next lines to my proguard according to the documentation https://firebase.google.com/docs/database/android/start/#proguard

# Add this global rule
-keepattributes Signature

# This rule will properly ProGuard all the model classes in
# the package com.yourcompany.models. Modify to fit the structure
# of your app.
-keepclassmembers class com.yourcompany.models.** {
 *;
}

my questions is:

1. Assuming that my package name is com.testing , should the added lines look like these?

   -keepattributes Signature

   -keepclassmembers class com.testing.models.** { *; }

OR the second line should be without the "models"? like this:

-keepclassmembers class com.testing.** {

2. Moreover, if I have only 1 global class named Data that I save to firebase, can I just keep these class members specifically? or I must act as shown above..

Answer 1

yes, it will look like this

-keepattributes Signature

-keepclassmembers class com.testing.models.** { *; }

If you have only one model class called Data, add the following lines instead

-keepattributes Signature

-keep class com.testing.models.Data { *; }
