Please, look this code!

Awesome addition!
Few suggestions:

• currently not working with boolean (.readBoolean() and .writeBoolean() doesn't exist into Parcel, you must use .writeByte((byte) (myBoolean ? 1 : 0)); and myBoolean = in.readByte() != 0;)
• It could be a good idea to separate this PR into two: one for Json and one for Parcelable.
• You made some changes on the coding style, this could prevent the greendao author to merge it as is.

To fix boolean parcelable issue, replace:

<#list entity.properties as property>
${property.propertyName} = in.read${property.parcelableTypeInEntity}();
</#list>    

By

<#list entity.properties as property>
<#if property.parcelableTypeInEntity == "Boolean">
${property.propertyName} = in.readByte() != 0;
<#else>
${property.propertyName} = in.read${property.parcelableTypeInEntity}();
</#if>
</#list>

And

<#list entity.properties as property>
dest.write${property.parcelableTypeInEntity}(${property.propertyName});
</#list>

By

<#list entity.properties as property>
<#if property.parcelableTypeInEntity == "Boolean">
dest.writeByte((byte) (${property.propertyName} ? 1 : 0));
<#else>
dest.write${property.parcelableTypeInEntity}(${property.propertyName});
</#if>
</#list>
