Hello how are you? I have a REST service that returns a list of pests with their respective images , tree for each plague , and when many images have memory problems in android.

I have configured the mapping as follows .

<classMappingDescriptor className="mobile.model.ExpertPlagaView" persisted="false">
      <crudServiceClass className="mobile.model.service.ExpertPlagaViewService" autoIncrementPrimaryKey="true" localPersistenceManager="oracle.ateam.sample.mobile.v2.persistence.manager.DBPersistenceManager" remotePersistenceManager="oracle.ateam.sample.mobile.v2.persistence.manager.RestJSONPersistenceManager" remoteReadInBackground="false" remoteWriteInBackground="true"
                        showWebServiceInvocationErrors="false" autoQuery="true" enableOfflineTransactions="true"/>
      <table name="EXPERT_PLAGA_VIEW">
         <primaryKeyColumn name="PLAGA_ENFERMEDAD_CULTIVO_ID"/>
      </table>
      <attributeMappings>
         <directMapping attributeName="actividadId" payloadAttributeName="actividadId" columnName="ACTIVIDAD_ID" columnDataType="NUMERIC" required="false" persisted="false" javaType="java.math.BigDecimal" keyAttribute="false"/>
         <directMapping attributeName="empresaId" payloadAttributeName="empresaId" columnName="EMPRESA_ID" columnDataType="NUMERIC" required="false" persisted="false" javaType="java.math.BigDecimal" keyAttribute="false"/>
         <directMapping attributeName="imagen" payloadAttributeName="imagen" columnName="IMAGEN"
                        columnDataType="VARCHAR2" required="false" persisted="false" javaType="java.lang.String" keyAttribute="false"/>
         <directMapping attributeName="imagen2" payloadAttributeName="imagen2" columnName="IMAGEN2"
                        columnDataType="VARCHAR2" required="false" persisted="false" javaType="java.lang.String" keyAttribute="false"/>
         <directMapping attributeName="imagen3" payloadAttributeName="imagen3" columnName="IMAGEN3"
                        columnDataType="VARCHAR2" required="false" persisted="false" javaType="java.lang.String" keyAttribute="false"/>
         <directMapping attributeName="nombreCientifico" payloadAttributeName="nombreCientifico" columnName="NOMBRE_CIENTIFICO" columnDataType="VARCHAR" required="false" persisted="false" javaType="java.lang.String" keyAttribute="false"/>
         <directMapping attributeName="nombreVulgar" payloadAttributeName="nombreVulgar" columnName="NOMBRE_VULGAR" columnDataType="VARCHAR" required="false" persisted="false" javaType="java.lang.String" keyAttribute="false"/>
         <directMapping attributeName="plagaEnfermedadCultivoId" payloadAttributeName="plagaEnfermedadCultivoId" columnName="PLAGA_ENFERMEDAD_CULTIVO_ID" columnDataType="NUMERIC" required="true" persisted="false" javaType="java.math.BigDecimal" keyAttribute="true"/>
         <directMapping attributeName="plagaMalezaEnfermedadId" payloadAttributeName="plagaMalezaEnfermedadId" columnName="PLAGA_MALEZA_ENFERMEDAD_ID" columnDataType="NUMERIC" required="false" persisted="false" javaType="java.math.BigDecimal" keyAttribute="false"/>
      </attributeMappings>
      
      
      <methods>
         <findAllMethod uri="/query/ExpertPlagaView.findAll" connectionName="Mobile" requestType="GET" secured="false" sendDataObjectAsPayload="false"
                        deleteLocalRows="false" payloadElementName="root">
            <headerParameter name="Content-Type" value="application/json"/>
         </findAllMethod>
      </methods>
   </classMappingDescriptor>

Entity:

public class ExpertPlagaView extends Entity {


    private BigDecimal actividadId;
    private BigDecimal empresaId;
    private String imagen;
    private String imagen2;
    private String imagen3;
    private String nombreCientifico;
    private String nombreVulgar;
    private BigDecimal plagaEnfermedadCultivoId;
    private BigDecimal plagaMalezaEnfermedadId;

On android device i have this error: java.lang.outofmemoryerror java heap space
