Android release app inserting wrong value in Firebase database

I have model class for storing value in Firebase database which is working fine for debug app but when I run in Release mode or generate release .apk wrong values are posted in my Firebase database (actual json is not posted).

     b: "[email protected]"

    -dontwarn sun.misc.Unsafe
    -dontwarn android.databinding.**
    -keep class android.databinding.** { *; }

Build Warnings 

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.

Difficult to give a very precise answer because you don't show the code.

I assume that you have somewhere code like this :

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

And then:

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

The problem is that the MyData gets obfuscated. There are 2 possible solutions then :

Either prevent obfuscation on MyData :

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

Or have a finer control over what is sent to firebase :

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 ;
    }
}

And then:

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

This solution should work event if MyData is obfuscated.

Hope this helps you.
