When I do the tests with apk-debug the data is stored with its correct key in FirebaseDatabase, as it was stipulated in the model.
But when I generate the apk-release, the data is saved but with different keys.
In the attached image frame in green, as they are, the data is left with the apk-debug and in red, as it is, when I generate the app in apk-release.
Do you know why this occurs? and What should I modify to solve it?
Thanks in advance to everyone
You must configure ProGuard to maintain the names of the properties of your models.
According to the Firebase documentation you must add this configuration to your proguard-rules.pro file:
# 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.** {
*;
}
(where com.yourcompany.models.** is the package your models are in)
